 CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 
 
 By JOHN P. FJNLEY, First Lieutenant, Ninth U. S. Infantry. 
 
 INTRODUCTION. 
 
 In the preparation of this monograph exhaustive investigation and discussion are not 
 attempted, although an effort has been made, within the time at the disposal of the writer, to 
 examine all information immediately available at the central office of the Weather Bureau. The 
 analysis of the data has largely been made with the view of throwing some light upon the funda- 
 mental causes of the occurrence of drought on the Northern Plains. 
 
 The subject is an important one and worthy of prolonged study. In the preparation of a more 
 extended report, methods of observation should be carefully examined, results made comparable 
 with greater precision, and due weight given to all variations from an accepted standard of com- 
 parison and verification. The data have been selected, arranged, and analyzed to broadly cover 
 the field of investigation, and suggest lines of comparative study and research to those who may 
 desire to pursue the subject specially, in certain directions. 
 
 Methods of treatment are explained and all the data employed in analysis and discussion are 
 given in some one, of three forms, viz: tabulations, diagrams, and charts. The opportunity is 
 thus afforded to any student of making other, more varied, and more exhaustive applications of 
 1 lit- fundamental values, as circumstances may suggest. A more complete analysis of the data 
 would have been interesting and valuable, especially abnormal peculiarities in precipitation, tem- 
 perature, and barometric pressure, on which some of the most iinportant.climatic features depend. 
 However, the work submitted Pn this direction will, it is hoped, offer the means of extending 
 research in various lines of climatic investigation with profit. 
 
 In the preparation of the base for all temperature and precipitation charts employed, only 
 such places appear as have been stations of observation for a mouth or more, from 1857 to 1891, 
 inclusive. Therefore every station upon the maps has some meteorological value attached to it, 
 the data from which appear in the tables wherever a satisfactory monthly value could be obtained. 
 Jn a few cases such values could not be secured, and consequently the tabulated list of stations 
 will not exactly coincide with the face of the charts. The base map is of particular value in show- 
 ing the distribution of points of observation over the territory under investigation, and to this 
 extent marking the weight to be given to certain sections as compared with the whole Brea. While 
 South Dakota has the greatest number of stations, their distribution is not altogether as satis- 
 factory as over North Dakota. The construction of two lines of railroads entirely across Forth 
 Dakota, from west to east, one over the southern and the other over the northern portion of the 
 State, has proved of great benefit in the establishment of weather reporting stations. 
 
 In South Dakota the lines of railway communication are confined to that portion of the State 
 east of the Missouri, except a short line running into the Black Hills from northwestern Nebraska. 
 The Sioux Indian Reservation has for many years interfered with the development of South Dakota 
 west of the Missouri, but the barrier is being gradually removed, and projected lines of communi- 
 cation will, before long, open up a vast country the climatology of which is as yet practically 
 unknown. If railroads are the pioneers of civilization and material prosperity, they are certainly 
 the means of acquiring those benefits in no small degree, through the opportunities afforded for

 the establishment of reliable meteorological statistics, upon which to construct climatologicnl 
 values of the utmost importance to agricultural and commercial interests. 
 
 On the whole, tins monograph will present to the public the most complete, comprehensive, 
 and accurate collection of meteorological and climatological data ever published for the Dakotas. 
 In this connection it is important to note that the records include the year 1891, thus securing a 
 large amount of additional information, the accomplishment of which has entailed much labor. 
 Data are furnished from stations in the region adjacent to and immediately surrounding the 
 Dakotas, and comparisons are made with records from selected stations at more distant points, in 
 order that differences in climatic effect may be instructively observed. Certain agricultural values 
 are also presented in tabular form from careful computations made by Mr. J. R. Dodge, the 
 Statistician of the Department of Agriculture. These records offer means of useful comparison 
 with climatological data. 
 
 The scope of the data collected in this report will afford opportunity for valuable study in 
 connection with the subject of irrigation, and in other directions, which in the brief discussion 
 submitted can not receive more than a passing , notice. It is intended that the value of this 
 monograph shall rest upon an accurate presentation of all available records, and also upon a 
 truthful and somewhat extended analysis of the data. The methods of examination and classifi- 
 cation are believed to be simple and practical, and it is expected that the information furnished 
 will be within reach of the agricultural and commercial classes. The actual records are submitted, 
 generally in detail and at their face value. If the method of treatment in any case does not appear 
 to meet the expectations or fancy of the casual reader, or the careful student, the opportunity is 
 afforded of applying his own ideas to the original values. In the discussion, effort is made to avoid 
 masking the truth by any tendency toward exaggeration or concealment. 
 
 Elaborate and involved methods of reasoning are not resulted to in support of preconceived 
 or doubtful theories. Deductions are given in brief form and reference is made to the source of 
 information with directness. Unfair comparisons have not been designed and undue advantage 
 is not purposely given to any one section over another. Under such circumstances no unjustifi- 
 able expectations can be aroused in the interest of any agricultural or commercial developments. 
 Endeavor has been made to present the actual records and all that pertains to them in such a 
 manner that each section of the two States represented will stand on its own resources and be 
 judged accordingly. Indications will be set against certain records, but the reader will be able to 
 measure the accuracy and usefulness of the application. 
 
 
 
 PHYSICAL FEATURES. 
 
 The region under discussion in this report embraces over 150,000 square miles, an area about 
 five times as great as the whole of New England. Its northern limit is 49 north latitude, wliiHi 
 parallel forms the boundary between the United States and the. Dominion of Canada west of the 
 ninety-fifth meridian. Its southern limit is marked by the forty-third parallel of north lati tin le 
 :iiid its eastern and western limits by the meridians of 90 20' and 104 west from Greenwich. 
 Its extreme length from north to south is about 430 miles and the width from east to west is 
 about 350 miles. The entire region is divided into two irregular portions by the course of the 
 Missouri, from northwest to southeast, and much the larger part of the two States is drained by 
 this great, river, which has a length within their boundaries of about 1,300 miles, when its tortuous 
 course is entirely considered. The Red River of the North forms the dividing line between North 
 Dakota and Minnesota and has a very devious course of about (500 miles before entering into Lake 
 Winnipeg, Manitoba, The valley of this river embraces an area of about 23,00(1 square miles, 
 about 8,000 of which are in North Dakota. The soil of this valley is very fertile and is said to 
 make the "finest wheat land in the world." 
 
 The river systems of the Dakotas are very extensive and of considerable value to the agricul- 
 tural and commercial interests of the States. Within the valley of the James, or Dakota River, 
 the greatest artesian wells in the world have been found, the possibilities of which for the purposes 
 of irrigation are enormous. The extraordinary supply of motive power along the rapid descent 
 of the Big Sioux River furnishes opportunities for manufacturing and other industries of great 
 commercial value. The two Dakotas are estimated to have a water surface of about J,. r .OO square

 miles (about oiie one-hundredth of the entire territory), considering the rivers and the large num- 
 ber of small lakes, the latter being practically confined to the country east of the Missouri and 
 predominating in South Dakota. The largest, Devils Lake, about 400 square miles, lies in north- 
 east North Dakota. 
 
 The general contour of the whole territory is a vast undulating plain, sloping gradually from 
 west to east. The accompanying profile sketch shows approximately the characteristic contour 
 features of the two States. 
 
 There are two mountain regions in the territory, one in north-central North Dakota, called 
 the Turtle Mountain, covering an area of about 800 square miles and having an altitude varying 
 from 1,000 to about 1,500 feet above sea level. The other region, known as the Black Hills, lies in 
 southeast South Dakota, and embraces an area of about 3,500 square miles, with an elevation 
 varying from 3,000 to nearly 10,000 feet above sea level. In northeast South Dakota is an elevated 
 plateau or range of hills, known as Coteau des Prairies, which reach a maximum elevation of 
 about 2,000 feet above sea level. A similar range, but of larger extent, called the Coteau du Mis- 
 souri, extends along the river of that name, the banks of which, near the central portion of the 
 territory, are about 1,500 feet above sea level. In some places these hills have a width of 45 miles 
 and their general trend is from northwest to southeast, for a distance of several hundred miles. 
 
 They form very nearly the western limit of the area adapted to agricultural purposes in both 
 States, though the opportunity afforded for grazing has a considerably greater limit to the westward. 
 In the report of the United States Northern Boundary Commission, Capt. Twining states that: 
 
 The surface of the Coteau consists of an irregular collection of pointed hillocks, growing more and more 
 irregular in design anil contour until they are merged in the Bad Lands. These Bad Lauds, or ' mauvaises terres," 
 as they are termed by tin; lialf-li reeds, set at defiance all rules of topography, as well as all adequate description. 
 Lacking even the continuous lines of drainage on which the eye may rest and which give form and system to an 
 ordinary terrain, they stretch in an endless and tiresome succession of arid and treeless hills and ridges, a tumult- 
 uous expanse of baked mud. 
 
 The surface of the whole lerritory is greatly varied, but, with the exception of the Black Hills, 
 an outlying range of the Rocky Mountains, there are no important summits in the two Dakotas. 
 A very considerable portion of the country is composed of irregular plateaus of moderate eleva- 
 tion, scattered over which are numerous isolated buttes (peaks) having an elevation above the 
 plains of from 500 to 1,500 feet. 
 
 The topographical and ' geological surveys of the Dakotas are yet far too incomplete to fur- 
 nish data upon which to base more than a very general and rather imperfect description of 
 their physical characteristics. It is evident from the limited information now obtainable that 
 marked local peculiarities abound in spite of what appears to be a general sameness of surface. 
 Under such circumstances corresponding vagaries of climatic condition maybe expected which 
 can only be, satisfactorily known by the most extensive and thorough system of meteorological 
 observations, and by an accurate hydrographic survey of the two States. 
 
 The only considerable areas of forest are to be found in the two mountain regions above 
 described. In the Black Hills there is estimated to be about 1,500 square miles of wooded 
 area. Along the river botlomsand about the lakes are occasionally heavy growths of timber. 
 TLe U. S. Geological Survey in 1889 estimated the approximate area, in square miles, of timber 
 land in North Dakota (river bottoms) as 200; in South Dakota, 2,800 square miles, only 400 of 
 which embraced merchantable timber. The cultivation of forest trees began in both Dakotas 
 in 1884, in accordance with the observance of Arbor Day, and very satisfactory results have 
 followed this enterprise. 
 
 METEOROLOGICAL 1{ F,< '< )Rt>S. 
 
 Meteorological observations in the Dakotas do not cover the vast area in a satisfactory manner, 
 
 but this statement need not create surprise if the undeveloped condition of the country is fully 
 
 realized and its pecularities of topography are understood. Most of the work accomplished has 
 
 naturally been confined to the territory east of the Missouri and principally in South Dakota.

10 CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTA8. 
 
 It is progressing quite rapidly with the march of civilization westward and the opening of new 
 lines of railway communication. 
 
 To the Medical Department of the Army must be accorded the credit of being the meteoro- 
 logical pioneers throughout the region of the great Northwest. The medical officers, at the 
 various military posts established in the Dakotas, began observations of temperature, rainfall, 
 wind direction, and state of weather in 1854, the first station being opened at Fort Pierre, 
 S. Dak., in January of that year. The next post was at Fort Randall, S. Dak., the observations 
 beginning in November, 1856. At other posts meteorological records began as follows: Fort 
 Abercrombie, N. Dak., February, 1859 ; Yankton Indian Agency, S. Dak., November, 1859; Fort 
 Berthold and Fort Buford, N. Dak., September, 1866; Fort Stevenson, N. Dak., August, 18G7; 
 Fort Totten, N. Dak., August, 1869. This distribution of stations of observation excluded south- 
 west Dakota, where meteorological records did not commence until 1878, by the establishment of 
 a Signal Service station at Deadwood in January of that year, followed in July, 1879, by observa- 
 tions at Fort .Meade, in the Black Hills, a short distance east of Dcadwood. Altogether seven 
 stations have, been established in the Black Hills for various periods of time since. January, 1878, 
 four of which are now in operation. 
 
 Following the initiatory work of the Medical Department of the Army came that of the 
 voluntary observer, through the instrumentality of the Smithsonian Institution. The first station 
 so established was at Yankton, S. Dak., in January, 1860; the next at Mouth Cherry, S. Dak., 
 April, 1861. Other early stations opened as follows: Bon Homme, S. Dak., .A I arch, 1872; Fargo, 
 N. Dak., December, 1872; Morriston, S. Dak., February, 1875; Webster, S. Dak.! June, 1.SS2; 
 Richardton, N. Dak., February, 1884. Voluntary observers began their work at places convenient 
 to established lines of communication, but yet they were well advanced to the outposts of civil- 
 ization, and their work manifests a very creditable appreciation of the practical value of clima- 
 fological data. 
 
 The Signal Service Bureau was established by Congress in the early part of 1870 and in 
 November of that year a number of regular stations of observation were opened. This Bureau 
 entered Dakota in 1872, establishing its first station at Fort Sully, S. Dak., on May 7 of that 
 \ear. The next at Pembina, N. Dak., November 1, 1872; Yankton, S. Dak., April], 1873; Mismarck, 
 N. Dak., September, 15, 1874; Fort Buford, N. Dak., February, 1879. 
 
 From January, 1854, to December, 1891, meterological observations have been taken at, 50 
 stations in North Dakota and 75 stations in South Dakota, a total of" 125 stations in both .States. 
 
 The length of records at these stations has varied from a month at a few points to 10 years at 
 Fort Vates and Fort Rice, N. Dak., and at Deadwood and Webster, S. Dak.; about 11 years at 
 Huron, S. Dak.; 18 years at Fort Meade, S. Dak.; 15 years at Fort Stevenson, N. Dak.; 17 years 
 at Mismarck and Fort Abercrombie, N. Dak. ; 18 years at Fort Abraham Lincoln, N. Dak.: 19. years 
 at Vankton, S. Dak.; 20 years at Fort Sissetou, S. Dak., and Fort Pembina, N. Dak.; 21 years 
 at Fort Totten. N. Dak.; 23 years at Fort Sully. S. Dak.; 20 years at Fort Buford, N. Dak.: and 
 :;."> years at Fort Randall, S. Dak. It will be seen that the average period over which observa- 
 tions have been taken is very nearly the same in both States, being about 18 years in North 
 Dakota and about 19 years in South Dakota. The maximum record of ::."> years occurs in extreme 
 southeastern South Dakota. The next highest, 26 years, occurs in extreme northwestern North 
 Dakota a rather singular comparison between the two States. 
 
 The hours of observation have been most varied at Signal Service stations. From November 1 , 
 1870, to December 31, 1884, observations were made at the following hours daily, Washington 
 time: 7, 7:35, and 11 a. m.; 12 noon; 3, 3:35, 4:35, 7, 11, and 11 :35 p. m. On January 1, 1885, time 
 was changed to the seventy-fifth meridian, eight minutes faster than Washington time. From 
 that date to June 30, 1888, the hours of observation were 7 and 11 a. m.; 3, 7, 10, and 11 "p. in. On 
 July 1, isss. the hours were changed and reduced to 8 a. m. and 8 p. m. Those now mentioned 
 formed the telegraphic series of observations. Observations at local time were taken at 7 a. m., 
 u and 9 p. m., from November 1, 1870, to July 1, 1881. 
 
 At voluntary stations the observations of temperature, wind direction, wind force (estimated), 
 and cloudiness have been generally taken at 7 a. in., 2 and 9 p. m., local time. At some stations 
 
CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 11 
 
 the hours were shortened to two of the same name, usually 8 a. m. and 8 p. m., or 9 a. m. and 9 p. 
 m. The amount of precipitation was observed once daily, unless abnormally heavy, at the most 
 convenient hour. 
 
 At military posts the hours of observation were changed from 7 a. m., 2 and 9 p. m., in the 
 autumn of 1888, to 8 a. m. and 8 p. m., or to any two hours of the same name from 7 a. m. to 9 a. m., 
 inclusive. At both voluntary and at military-post hospital stations observations have always been 
 taken at local time. The mean temperature from three observations has been determined by 
 taking one-fourth of the sum of the 7 a. m., 2 p. m., and twice the 9 p. m. The mean from 
 two observations of the same name has been obtained by taking one-half of their sum. These 
 rules apply to the local and two-hour observations of the same name at Signal Service and 
 Weather Bureau stations. 
 
 The means of pressure, temperature, humidity, aad-dew-point, computed from the synchronous 
 tridaily telegraphic observations, taken at Signal Service stations, at 7:35 a. m., 4:35 and 11:35 
 p. m., or 7 a. m., 3 and 11 p. m., or 7 a. m., 3 and 10 p. m., have been obtained by taking one-third 
 of the sum of the three observations. Precipitation was measured three times daily from Novem- 
 ber 1, 1870, to June 30, 1888, and thereafter twice daily at the telegraphic observations. At Cana- 
 dian stations the hours of observation have been the same, with corresponding changes, as the 
 tri-daily and twice-daily telegraphic observations at Signal Service and Weather Bureau stations. 
 
 From what lias preceded it will be seen that the records of temperature and precipitation given 
 in Appendices Nos. 4 and 40 combine the work of three classes of observers, the most accurate 
 and systematic of which have been those of the Signal Service and Weather Bureau. The 
 observations vary, not only as to character of work performed, but as to methods pursued and as 
 to quality of instruments employed. Such results have been combined in monthly and annual 
 averages at those stations where it was necessary to do so in order to secure a continuous record 
 of the maximum period for which observations had been taken. This method gives less satisfactory 
 results for precipitation than for temperature. In order that comparison may be made with more 
 uniform observations^ and perhaps more accurate and acceptable computations, in the case or 
 temperature, three sets of monthly and annual temperature normals for different periods, of eight, 
 nine, and ten years each, prepared exclusively from Signal Service and Weather Bureau obser- 
 vations, are furnished in Appendices Nos. 42, 43, and 44. The results from combined records are 
 expected to vary, because of different causes, there being present in the determinations varying 
 hours of observation, different periods of time, quality of .work, and quality and kind of instru- 
 ments employed. From a cursory examination it would seem that the longest record gives, gen- 
 erally, the best result in spite of the want of uniform methods of work. Comparison made with 
 the standard normal values shows the pronounced effect from warm and cold periods, of few 
 years' duration, or even one season, as occurred in the abnormally warm winter in 1891. 
 
 In the case of precipitation two sources of error appear in the records from voluntary observers 
 and military-post hospitals, but greater in the former than in the latter, viz: (1) imperfect 
 measurement of snowfall and its reduction to rain; (2) defective apparatus for the measurement of 
 rainfall and want of care in measuring and recording the amount collected in the gauge. The Signal 
 Service and Weather Bureau records are more uniform and more accurate in these respects than 
 those obtained from other sources. The degree of this accuracy can only be spoken of in a general 
 way and will doubtless vary v.ith every station, being more at some and less at others. But, 
 aside from such a result, it must be conceded that the influence of locality and topography demand 
 the most careful consideration in applying any correction for supposed erroneous methods of work 
 in the measurement of precipitation. It is well known that the distribution of rainfall is subject 
 to many and sometimes seemingly inexplicable variations, due to the conditions of exposure of 
 the collecting apparatus and to the peculiarities of local topography. This fact being conceded, it 
 becomes necessary to increase the number of stations of observation, as far as possible, and 
 accept all records, even though each and every one can not be subjected to the same standard 
 of criticism. In spite of the fact that other things may not be equal, the longer the record of pre- 
 cipitation the more satisfactory the monthly and average values become. In the case of isolated 
 records showing abnormal variations the data must become of considerable value. 
 
12 CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 
 
 In accordance with these views the precipitation records in Appendix No. 4 have been 
 combined from all sources at each station, in order to secure the maximum continuity of obser- 
 vations. The precipitations and temperature records in Appendices Nos. 4 and 40 have been 
 employed as the basis of construction of all charts of these elements, also diagrams, and in the 
 preparation of supplemental tables in extending the analysis of meteorological data. 
 
 PRECIPITATION. 
 
 An accurate knowledge of the rainfall of any considerable region of country is indispensable to 
 a satisfactory estimate of its productiveness. The fundamental source of material prosperity and 
 commercial supremacy in any country lies in the products of the soil, the development of which 
 depends upon the amount and distribution of atmospheric precipitation, direct, or through the 
 instrumentality of irrigation. It is the most important element for discussion in this monograph, 
 aside from evaporation, and also the most difficult for thorough treatment. The immense area 
 embraced by the Dakotas, the limited number of stations of observation, and the lack of uniform 
 and continuous methods of work at all places render the data submitted inadequate for a satis- 
 factory representation of the rainfall, especially west of the Missouri River. 
 
 Precipitation has received consideration in the preparation of twenty-nine charts, forty-two 
 diagrams, and nineteen tabulations, published in this monograph. The fundamental data for 
 classification and analytical study have been obtained from the records published in Appendix 
 No. 4. The cartographical representation of the monthly and annual average values has been 
 prepared without the usual employment of isometric lines. The thirteen charts here referred to 
 will be found in Appendices Nos. 27 to 39, inclusive. Recourse has been had to this rather 
 novel and perhaps doubtful method of representation because of the rather remarkable differ- 
 ences in isohyetal values, the small number of stations from which normal values could be 
 obtained, and the large scale of the charts. It is believed, however, that the plan adopted will 
 better serve to convey the truth than the employment of uncertain methods, of perhaps more 
 graphic illustration. The values for each station are entered in very large figures, to aid the eye 
 in locating them quickly and in making comparisons with surrounding stations. Peculiarities 
 are thus prominently set forth, and with a degree of accuracy that prohibits criticism and pre- 
 vents an unfair distribution of theoretical curves. Isolated stations are not neglected, and large 
 areas are not given a shading of supposititious value. By the methods pursued due weight is 
 given to stations of long and short records and consideration had for the influence, of local topog- 
 raphy. The charts have entered upon them monthly and annual values of from three to thirty- 
 five years, and in the extremes, on the average, from five to seventeen years, obtained from a 
 total of forty stations. The agreement between the longest records is, on the whole, better than 
 between the long and short ones, as might be expected; yet this disagreement is much less marked 
 from April to September, inclusive, than during the remainder of t lie \ ea r, from October to March, 
 inclusive. 
 
 The hyetography of the Dakotas presents peculiar features of local divergence that seem 
 inexplicable from topographical influences alone. From a general view of the face of the country 
 one would expect to find a remarkable uniformity of precipitation expressed in the monthly aver- 
 age values of three years or more, and especially in the annual values. While the precipitation 
 records are a. little more complete and of somewhat greater length than those of mean tempera 
 ture, yet the corresponding increase in value is extremely small because of the much greater 
 length required for precipitation records in order to secure satisfactory normal values. The. 
 advisability of charting three-year records of rainfall may be questioned; yet those of ten year's 
 and over, aggregating twenty stations, were not sufficient in number, when properly distributed, 
 to cover the territory. Moreover, considerable differences were found among the long records, 
 and in some cases they were greater than those found to exist bet ween the long and short records, 
 where reasonable comparison could be made. However, the averages show that the differences 
 between the short records in North Dakota in the winter months (dry season) are about 65 per cent 
 greater than those existing between the long records, the mean difference being about one-third 
 of an inch. On the contrary, in South Dakota, the differences between I he long reci >rds are about 
 10 per cent greater than between the short records, the mean difference being about one-tenth

 of an inch. For the summer months (wet season) the average. differences are about 45 per cent 
 greater for the short records in North Dakota, the mean difference being about seven-tenths of 
 an inch. In South Dakota the average differences for the short records are about 35 per cent 
 greater, the mean difference being about four-tenths of an inch. 
 
 Considering the long records by themselves the average differences in South Dakota during I he 
 \vinler months (dry season) are about 70 per cent greater than exist in North Dakota, the mean 
 difference being about four-tenths of an inch. During the summer months (wet season) the 
 average differences in South Dakota are about 55 per cent greater than in North Dakota, the 
 mean difference being about 1.2 inches. 
 
 Considering the short records in similar periods it is found that the average differences in 
 South Dakota during the winter months (dry season) are about 35 per cent greater than those in 
 North Dakota, the mean difference being about half an inch. In the summer months (dry season) 
 the average differences in North Dakota are about 30 per cent greater than in South Dakota, the 
 mean difference being about 1.3 inches. 
 
 From these comparisons it is evident that the short records show considerable uniformity 
 although the observations were made for quite widely different years. It is important to state, 
 however, that most of the short records are confined to the period between 1887 and 1891. There is 
 also developed such a relation to the long records as to warrant the belief that the distribution of 
 rainfall over the Dakotas is subject to rather marked local peculiarities, which can only be fully 
 appreciated by largely extending the present system of rainfall observers. If the greater vari- 
 ations in rainfall in South Dakota, as disclosed by the records, are due in part to the greater 
 number of stations and the larger area covered, it is simply additional evidence in support of the 
 existence of decided local features. In this connection it is deemed advisable to invite particular 
 attention to the records at Kichardton, N. Dak., and Webster, S. Dak., the former covering a 
 period of nearly five years and the latter about ten years. The precipitation at both stations ap- 
 pears excessive and much at variance with surrounding points. It was first assumed that errors 
 were made in measuring and reducing the snowfall, but throughout the year the excess is main- 
 tained at both stations, although somewhat greater in winter than in summer. There has been 
 no change in observers and both have reported to the Weather Bureau that their observations 
 were properly made and recorded from standard instruments. These instruments were furnished 
 to the observers by the Signal-Service Bureau. Peculiarities are also manifested in the records 
 from Alexandria, Olivet, and Parkston, S. Dak., and also at Fort Seward, N. Dak. At the large 
 majority of voluntary stations in both Dakotas standard Weather Bureau instruments have been 
 employed, which fact seems to justify the expectation of fairly reliable observations, as the in- 
 struments so furnished carry with them specially prepared instructions as to their use. 
 
 Perhaps the most unsatisfactory work in rainfall observation arises from broken and incomplete 
 records, seriously interfering with the determination of reliable monthly and annual normal 
 values. The results met with in this respect have certainly been very unfortunate, and it is hoped 
 that in succeeding years the great importance of accurate and complete precipitation records may 
 be more fully appreciated by all classes of observers. 
 
 It is not to be assumed, however, that the rainfall records at Weather Bureau stations, whether 
 long or short, give a correct knowledge of the distribution of precipitation over any region simply 
 because of their greater accuracy. These regular stations are necessarily few in number in any 
 State and are not always located to the best advantage for representing the distribution of rainfall. 
 Moreover, their small number essentially prohibits such a result. The efforts of voluntary observ- 
 ers must be relied upon to support the work of the regular stations, which can never be considered 
 more than a nucleus of standard value around which the former may be gathered for comparative 
 study and the development of distinctive features. The records from regular stations are indis- 
 pensable to the study and forecasting of daily weather changes because the daily observations 
 are concentrated at suitable points for immediate consideration, through the aid of the electric 
 telegraph. 
 
 A further study of charts and tables reveals some important features, as follows: 
 
 1. The month of least precipitation is November, followed next in order by January. 
 
 2. The month of greatest precipitation is June, followed next in order by May or July. 
 
14 CERTAIN CLIMATIC FEATURES OP THE TWO DAKOTAS. 
 
 3. Precipitation increases from an average of about one-tialf inch in November to nearly 4 
 inches in June, the increase in South Dakota being about 5 per cent, greater than in North Dakota. 
 
 4. The mean annual precipitation in North Dakota varies from about 13 inches at Fort Buford 
 to about 26 inches at Richardton and 20 inches at Fort Pembina; the average for the whole State, 
 computed from 14 stations, being about 17 inches. 
 
 5. The mean annual precipitation in South Dakota varies from a>bout 17 inches at Fort Sully to 
 over 28 inches at Deadwood and over 38 inches at Webster; the average for the whole State, com- 
 puted from 21 stations, being about 22 inches. 
 
 6. Aside from the rather doubtful record at Webster, S. Dak., the region of greatest precipit a- 
 t ion, considering both States, is found in the Black Hills. This applies not only to the snowfall o! 
 winter, but to the rainfall of spring and summer. In this connection it is important to bear in 
 mind that the Black Hills are the heaviest wooded region in either State. 
 
 7. The mean annual precipitation of the Red River Valley varies from about 15 inches at Fort 
 Kice, N. Dak., to 23 inches at Winnipeg, Manitoba, and 24 inches at Moorhead, Minn.; the average 
 computed from 6 long-record stations being about 20 inches. 
 
 8. The mean annual precipitation of extreme eastern South Dakota varies from about 16 
 inches at Brookings to about 22 inches at Fort Sisseton and 38 inches at Webster; the average 
 being about 25 inches. 
 
 9. The mean annual precipitation of the James River Valley varies from 15 inches at Fort 
 Sewanl, N. Dak., to about 26 inches at Olivet and Yankton and 27 inches at Morriston, S. Dak. 
 The average; computed from 8 stations is about 22 inches, the portion in North Dakota giving an 
 average of over 16 inches, while that in South Dakota rises to over 25 inches. 
 
 10. The mean annual precipitation of the Missouri River Valley varies from about 13 inches 
 at Fort Buford to over 20 inches at Fort Randall, the average for the whole valley, computed from 
 
 stations, being 17 inches. The portion in North Dakota has an average, of 16 inches and that 
 in South I )akota over 18 inches. 
 
 11. The monthly and annual average precipitation from selected stations given in Appendix 
 No. 6 furnishes interesting and valuable comparisons with surrounding territory, having both 
 greater and less rainfall than occurs within the Dakotas. It is evident that the region of least, 
 rainfall between the forty- first and fifty-fifth parallels and west of the ninetieth meridian (annual 
 average about 9 to 13 inches) lies in northern Wyoming and eastern Montana. The Dakotas lie 
 to the eastward of this arid region and make the nearest approach to it in northwestern North 
 Dakota. 
 
 12. In Appendix No. 7 will be found the monthly and annual amounts and averages of snow- 
 fall at certain stations in I lie Dakolas. The records are not altogether satisfactory, owing to the 
 imperfect manner in which I lie measurements of unmelted snow have been made and the uncertainty 
 in separating this element from rainfall. Prior to 1885, at Signal Service stations, the snowfall was 
 not recorded separately and without reduction. The exceedingly small amount of snow is one of 
 
 1 lie. most, striking features of the tabulation and reveals one of the unfavorable points in the clima- 
 tology of the Dakotas. The Black Hills show the largest amount of snowfall, as was also thecase 
 with rainfall. The records appear to show that the snowfall is heaviest in South Dakota and 
 least in North Dakota. It is also generally heavy in the Red River Valley and in extreme east- 
 ern South Dakota. As to the months of heaviest fall the maximum is reached in February in 
 North Dakota and in March in South Dakota. 
 
 13. Considering the distribution of snow over that portii f the United States and Canada 
 
 where it usually falls, the Dakotas lie within the region of the minimum amount (annual average, 
 1 to 2 feet), which includes Wyoming and eastern Montana. The regions of maximum amount 
 (annual average 10 to 30 feet) are the Sierra Nevada Mountains in northeastern California and the 
 I 'rovince of Quebec in Canada. 
 
 14. The amount of unmelted snow on the ground at the end of month, as shown in Appendix 
 No. 8, discloses the fact that the snowfall of the Dakotas disappears quite rapidly. But as the 
 low temperatures of the snowfall season would preclude much melting it is perhaps fair to assume 
 that the high winds of winter are largely responsible for the disappearance. Moreover, the vast 
 plains in both States afford great advantage to the sweeping high winds in removing the snow. 
 
CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 
 
 15 
 
 The snowfall disappears most rapidly in the interior of both States, and least rapidly in the Black 
 Hills and in the Bed River Valley. 
 
 15. In Appendices Nos. 15 ;md 16 are tabulated the occurrences of excessive precipitation in 
 both Dakotas. Monthly amounts equaling or exceeding 10 inches have occurred only twice in North 
 Dakota and but eight times in South Dakota since 1871. The, heaviest monthly rainfall in either 
 State. (14.05 inches) was reported from Webster, S. Dak., in June, 1884. The heaviest in North 
 Dakota (10.93 inches) was reported from Fort Abraham Lincoln in June, 1890. The largest 24-hour 
 rainfall in cither State (8 inches) was reported from Morriston, S. Dak., on July 22 and 23, 1878. 
 The largest 2-1-hour rainfall in North Dakota (5.10 inches) was reported from Fort Totten, on 
 August '2~> and 20, 1880. The greatest rainfall in less than two hours in either State (4.84 inches) 
 was reported from Webster, S. Dak., on July 2, 1881, as occurring in one hour and forty-five min- 
 utes. The greatest rainfall iu less than two hours in North Dakota (4 inches) was reported from 
 Steele on June 14, 1891, as occurring in one hour and twenty minutes. It is evident from these 
 records that the Dakotas are not liable to severe loss from flood, although the contour of the 
 country is such, in some localities, as to drain off both the extreme and also the average excessive 
 precipitation with detriment to the land, and with liability to damage other property to a degree 
 that deserves to lie guarded against. 
 
 1C). A fundamental consideration of any periodical distribution of precipitation in the Dakotas 
 is impracticable without correlative!}' discussing the distribution of atmospheric pressure over these 
 States and the immediately adjacent region. In order that this important relation may be appre- 
 ciated as far as the purposes of this monograph will permit, a graphic presentation has been 
 made by the preparation of monthly charts of areas of low barometric pressure (see Appendices 
 Nos. 137 to 1 IS, inclusive) and by the use of diagrams to show the comparative curves of monthly 
 deviations from normal values (see Appendices No. !>!) to 138, inclusive). 
 
 17. The charts of tracks of centers of low pressure show that the Dakotas lie in the path of all 
 barometric depressions moving' eastward over the country from the Pacific Ocean. The black 
 lines represent the direction of progressive movement of the low centers by connecting the plotted 
 points designating those centers, at certain times each twentv-four hours. 
 
 IS. The distribution of precipitation over the continent between the fortieth and fifty-fifth 
 parallels north latitude, shows that the areas of low pressure drop the maximum amount of their 
 moisture, west of the one hundred and twentieth meridian, and that from there eastward the rain- 
 fall diminishes rapidly to a minimum between the one hundred and fifth and one hundred and 
 tenth meridians, and thence increases again to a second maximum between the ninetieth and 
 seventy-fifth meridians, but south of the fort ieth parallel. The source of the first maximum is 
 found in the moisture gathered by cyclonic circulation from the warm waters of the Japan cur- 
 rent in the North Pacific. The source of the second maximum is obtained in a similar manner 
 from the Gulf and Gulf Stream. The probable cause of the minimum average annual precipi- 
 tation between the one hundred and fifth and one hundred and tenth meridians is found in the 
 fact of the great distance of this district from the two regions of maximum moisture supply to the 
 continent of North America, viz: the Japan current and the Gulf and Gulf stream. 
 
 19. The major portion of the Dakotas appears to lie too far west and north of the path of 
 northward air movement and the moisture supply from the Gulf. The bulk of the supply, under 
 the influence of cyclonic circulation, tending northward is deposited east of the one hundredth 
 meridian and south of the forty-third parallel. 
 
 20. The low-pressure areas are nearly drained of their moisture at the very coast line on the 
 Pacific, and during the remainder of the journey to the great continental valley of the Mississippi 
 no source of moisture supply can be drawn upon, except the snow beds of the great mountain sys- 
 tems between the one hundred and twentieth and one hundredth meridians, which in any event 
 could furnish but a limited and uncertain amount. In this connection it is well to state that a 
 significant relation seems to exist between the snowfall of the most elevated mountain ranges and 
 the rainfall of summer, over the, Northern plains. A deficiency in snowfall appears to correspond 
 with a deficiency iu rainfall, and vice versa. In order to illustrate the importance of this matter 
 from a practical standpoint typical charts of barometric pressure have been prepared to show the 
 conditions under which a deficiency of snowfall occurs in the Rocky Mountain and Sierra Nevada 
 
16 CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 
 
 regions, and also in a similar manner to show the distribution of mean atmospheric pressure under 
 which an excess of snowfall occurs over the same regions. These charts have been prepared from a 
 consideration of all the monthly values of mean barometric pressure since 1872 as published by the 
 Signal Service. The ideal character of the charts is explained on pages 17 and IS with those sub- 
 mitted on the occurrence of variations in rainfall. An examination of the typical chart for defici- 
 ency of snowfall reveals the fact that the mountain regions west of the one hundred and second 
 meridian are under the influence of a preponderance of cold, dry air of high density. Such a pre- 
 vailing characteristic in the distribution of mean atmospheric pressure indicates that a majority 
 of all low-pressure areas have been diverted away from the region under the control of this High, 
 and that they will continue to be so diverted until a decided change occurs in the mean pressure. 
 When the Lows are thus prevented from passing over the mountain regions in question the distri 
 hution of precipitation is, of course, very materially modified and reduced to a minimum. A notable 
 example under this type chart is found in January, 1889, and reference to the deficiency in snow- 
 fall is made in the Monthly Weather Review as follows : 
 
 While in some portions of the country (viz, northern New York and the northern portion of the Upper Lake 
 region) the monthly snowfalls have been heavy, and have prohahly equaled or exceeded the January average, 
 as a whole the snowfalls of January, like those of the two preceding months, have hern unusually small. There 
 can be no doubt that the winter snowfall to the close of January over much oi' tin- country, particularly the (in 
 tral and southern portions, i the smallest that has occurred for a number of years. 
 
 In the following month (February, 1889) precipitation remained considerably below the normal 
 in the Plateau and Pacific coast regions. In March, 1889, the Monthly Weather Review state* as 
 follows : 
 
 To the northward of the fortieth parallel the line indicating the snow limit over the western part of the coun- 
 try curves southeastward over the Plateau region of the Rocky Mountains, forming an enlongated area, within which 
 no snow was reported, extending from Washiugton and the northeastern part of Oregon to western ( 'olnrado. 
 
 It is well known that the summer of 1889 was a remarkably dry one in the I >a kolas. By ref- 
 erence to Appendix No. 14 it will be seen that the total deficiency in precipitation over the Dakotas 
 for 1889 was over 65 inches (about 7,500 tons of water to the acre) computed from the records of 
 nineteen stations. 
 
 21. The following typical chart showing the conditions under which excess of snowfall occurs 
 over the Rocky Mountain and Sierra Nevada regions discloses a distribution of mean monthly atmos- 
 pheric pressure, directly opposite to that displayed on the typical chart for deficiency of snowfall. 
 The conditions for excess of snowfall indicate that the areas of low barometric pressure from the 
 Pacific ocean have passed eastward directly over the mountain regions, and that they will continue 
 to do so until a decided change has been effected in the mean pressure over those regions. An im- 
 portant example under this head is found in February, 1891. The Monthly Weather Review for 
 that month records the occurrence of unusual snowfalls in the southern and western portions of 
 the United States. Snow fell as far south as Meridian, Miss., for the first time in three years. 
 It reached a depth of 120 inches at Cisco, Cal., and 104 inches at Alta, Utah. An unusually heavy 
 snowstorm prevailed in the middle Missouri Valley and the extreme Northwest, seriously inter- 
 rupting railroad traffic and causing the death of large numbers of cattle on the ranges. Precipi- 
 tation was in excess of the normal as follows: Northeast slope of the Rocky Mountains, 130 per 
 cent; Northern plateau, 129 per cent; Middle plateau, 108 per cent; Southern plateau, 219 per cent; 
 Middle Pacific coast, 250 per cent. In March, 1891, the Monthly Weather Review reports excess of 
 precipitation as follows : Northeast slope of the Rocky Mountains, 270 percent; Middle Eastern 
 slope, 253 per cent; Middle plateau, 208 per cent; Southeast slope, 140 per cent. The summer of 
 1891 in the Dakotas was marked by a notable excess of precipitation. By reference to Appendix 
 No. 14 it will be seen that the total excess, as computed from sixteen long-record stations, amounts 
 to over 40 inches (about 4,600 tons of water to the acre). The reports of the U. S. Department of 
 Agriculture show that the year 1891 was an extremely favorable one for crop production generally 
 throughout the Dakotas, or at least for that portion of them east of the Missouri River. 
 
 It is believed that from a study, of the distribution of mean atmospheric pressure depicted 
 on these typical charts information can be obtained which \\ill permit of some, long range fore- 
 casting as to the probable occurrence of excesses and deficiencies in precipitation over the North- 
 ern plains.

CEKTAIN CLIMATIO FEATUKES OF THE TWO DAKOTAS. 17 
 
 22. An examination of storm-track charts of the Dakotas for a long series of years reveals 
 monthly and annual fluctuations from the average path of easterly movement which bear impor- 
 tant relation to the distribution of both precipitation and temperature. These deviations arc only 
 in two directions, viz, north and south. The former corresponds to warm, dry weather and the 
 latter to cold, wet weather. Illustrations of these results are given in Appendices Nos. 21 to 26, 
 inclusive, and in Nos. 58 to 01. inclusive. 
 
 2.'!. The study of the storm-track charts in relation to the wet and dry seasons furnishes very 
 interesting and valuable comparisons. The amount of precipitation over any area depends not 
 so much upon the number of storm centers passing over it as upon the rate of progressive velocity 
 of those centers. The number of low-pressure areas as shown in Appendix No. 143 is greatest 
 during autumn and winter and least during spring and summer. The following monthly average 
 progressive velocities, in miles per hour, of the centers of both low and high-pressure areas, 
 computed from records for five years (1887 to 1S!U), show that the lowest velocities occur during 
 the season of greatest precipitation.

 This amounts to saying that the more slowly a storm center moves the more moisture it will 
 deposit upon the earth if the supply remains practically constant. The distribution of mean atmos- 
 pheric pressure over the interior of continents during the summer season is favorable to the 
 sluggish movement of all large disturbances. 
 
 24. A comparison of the storm-track charts for the various months discloses a remarkable 
 change in the curvature of the paths of low pressure areas across the Dakotas. During the dry 
 season the deviations from a direct east and west line are very small, showing rapid progressive 
 movement. But in the wet season (April to August inclusive) convolutions become extremely 
 frequent, so that the five-year chart record for the month of June (month of greatest rainfall) 
 becomes a labyrinth of winding lines. 
 
 25. A further application of the relation of barometric pressure to the occurrence and distri- 
 bution of precipitation is shown in the preparation of the following typical dry and wet weather 
 charts. They are termed "ideal" because their composite structure is not the result of the reduc- 
 tion of actual mean values for a large number of months, but rather the reduction- of isometric 
 lines; the former method is preferable because more accurate,and would have been followed in this 
 report but for the large amount of labor involved. It seems reasonable, however, to assume that 
 the charts will be found suggestive in t heir present form, to a degree .that may give practical results 
 in long range forecast ing. If, for example, the mean barometric pressure for April or May should 
 disclose a wet weather type, an excess of precipitation may reasonably be ex peeled for the next 
 month or two. Under favorable, conditions for its existence it would appear to take that long for 
 the type and its effect to disappear. An examination of the wet-weather type chart reveals the 
 existence of a sort, of barometric trough of low pressure embracing the Kocky Mountain region 
 and extending from British America, to Mexico. During the prevalence of such a distribution of 
 mean atmospheric pressure the areas of low barometer from the Pacific are found to pass eastward 
 over the Dakotas, and at a much lower latitude than in the event of a period of dry weather, I he 
 condition of the atmosphere as to moisture and density being most favorable to a. prevailing south- 
 erly air movement. It is generally found that lows tend to move in the direction of greatest, mois- 
 ture and towards the region where the existing atmospheric circulation most readily conforms to 
 the requirements of the passing storm center. In wet weather the lows trend southward but in 
 dry weather their deviation from the average course, is decidedly northward. An example of wet- 
 weal her deviation is shown in Appendices Nos. 25 and 20, where the. total excess of precipitation 
 as compared with normal values for many years, amounted to 82.87 inches (about 9,400 tons of 
 water to the acre), computed from the records of fifteen stations. 
 
 20. The dry-weather type chart shows a disposition of mean atmospheric pressure north of the 
 fortieth parallel which has been found to be decidedly unfavorable to the development of low- 
 pressure areas. Such a condition of atmospheric pressure not only aflects the latitude of theeast- 
 S. Ex. 157 3 
 
18 CKHTAIN CLIMATIC- FEATURES OF THE TWO DAKOTAS. 
 
 erly movement of lows from the Pacific, but it tends to materially redu.ro the number of such dis- 
 turbances and to increase their progressive velocity, all of which are agencies in the reduction of 
 precipitation over the Dakotas. Examples of dry-weather periods are given in Appendices Nos. 
 L'l to 24, inclusive. During one of these periods the deficiency of precipitation, as compared with 
 normal values for many years, shows a total loss of 72.93 inches (about 8, .">()() tons of water to the 
 acre) over the Dakotas, computed from the records of twenty stations. Another dry period shows 
 a total deficiency of 5(1.05 inches (about 5,700 tons of water to the acre) computed from the records 
 of fourteen stations. 
 
 27. If the employment of these typical charts can be depended upon, the foreknowledge to be 
 obtained from their study is of such a character that, even when expressed with a moderate degree 
 of certainty, and properly distributed to the public, will prove of considerable value to agricultural 
 and commercial interests. The success or failure of the most valuable crops, fruits, vegetables, or 
 cereals very often depends upon the occurrence of a few days of abnormal weather changes, and 
 especially so at the critical period of growth. Accurately prepared composite type charts, for 
 various sections of the country, subjected to revision in order to take advantage of every confirma- 
 tory occurrence, should be made the subject of careful study by the forecast officials of the Weather 
 Bureau. The wet and dry weather type charts submitted relate especially to the wet season in 
 the Dakotas. Similar types but not so strongly marked will exhibit the conditions which give rise 
 to corresponding changes in precipitation during the remainder of the year. This explanation 
 will apply to the type charts concerning snowfall and also temperature. 
 
 DROUGHT. 
 
 Liability to a marked deficiency in rainfall over any region is a matter of the utmost practical 
 value to both. agricultural and commercial interests. Damage from excess of precipitation is not, 
 so great and can be more easily provided against. The limits of agriculture and horticulture are 
 determined by the dry season for any region. In discussing the distribution of precipitation over 
 large, areas of country Dr. Hellman has made known the fact that in Spain marked differences in 
 social and agricultural conditions have appeared between sections where the rainfall is in excess 
 and where, it is deficient. The differences are of such a degree that they appear to control the 
 character and mode of life of the inhabitants. 
 
 In the discussion of this question it is of the utmost importance to have exhaustive experiments 
 and observations made to ascertain what, degree of dryness the various food forms of plant life will 
 submit to without destruction, and what amount of moisture will secure the best results in the full 
 development of each variety. The scope of work to be assigned to the Agricultural Experiment 
 Stations might profit ably embrace investigation of this character. The field is a broad and rather 
 difficult one for it includes the whole subject of atmospheric pressure, evaporation, and condensa- 
 tion, in which meteorology must have the cooperation of botany, chemistry, and geology to satis- 
 factorily contend with the problems involved. 
 
 In the limited investigation made in this monograph research has been confined to such meteoro- 
 logical data as could be made most readily available from the records of the Weather Bureau. 
 The method of treatment has been gradually developed by .suggestions arising from a study of the 
 fundamental data embraced in the tabulations, charts, and diagrams. 
 
 References to various authorities on climatic changes and the distribution of precipitation 
 developed the fact that, as a meteorological condition, drought has apparently been considered 
 only as a variation of the occurrence of rainfall, to such a degree as to injure vegetation. It would 
 appear that drought, in the full meteorological sense of that term, has never been defined. In the 
 New Century Dictionary the following definition appears: "Want of rain or of moisture; such a 
 continuance of dry weather as injuriously affects vegetation." This is true as far as it goes, but 
 the definition falls considerably short of completeness and does not touch the source of the essen- 
 tial atmospheric conditions involved in the occurrence of drought. 
 
 Drought as it has been studied in this report, and as the results of the investigation seem to 
 show, has a closer relation to evaporation than to precipitation, and is more dependent upon the 
 distribution of atmospheric pressure than upon the variation of any other meteorological element. 
 Drought may therefore be brielly defined as that state of the weather over any region, within and

 about which the distribution of atmospheric pressure is most favorable, for the occurrence of Hie, 
 minimum amount of precipitation and the maximum degree of evaporation; a strong- component 
 being wind force, the result of which is to cause injury to both animal and plant life by the devel- 
 opment of a high degree of aridity. 
 
 The actual precipitation of a district might be entirely adequate for its industrial needs were 
 it not for the influence of abnormal evaporation. To discuss the nature and extent of this 
 influence involves a consideration of all the elements which enter into the process of evaporation 
 and which retard or accelerate it. Evaporation from land areas, both cultivated and uncul- 
 tivated, as well as from bodies of water, is here referred to. The elements may be briefly 
 enumerated as follows: Temperature of the air, force of the wind; direction of the wind, accord- 
 ing to the humidity of the locality from whence it blows; atmospheric pressure, aridity of the air, 
 degree of cloudiness, character and extent of vegetation, proximity and extent of forests, char- 
 acter of .surface soil, temperature and humidity of soil, character of subsoil, area and depth of 
 water forming the evaporating surface, radiation, of surrounding bodies; dryuess, stillness and 
 density of the, air over the evaporating surface. 
 
 Prof. Russell says that 
 
 The amount of evaporation depends principally on the dryness of the air and the velocity of the wind blowing 
 
 over Hie, evaporating surface. The, measure, of the dryness of the air is the difference in vapor tension correspond- 
 ing l.o Hie temperature of the air and that corresponding to the, temperature of the dew point. 
 
 As to the values given in Appendix No. 83, Eussell states that they only 
 
 Represent possibilities of evaporation and not actual evaporation over the whole surface of the country. If a 
 set of figures were prepared from the various parts of the country which would represent the opportunities of 
 evaporation, which depend on the relative amount of land and water surface, and on the wetness or dryness of soil, 
 and the amount and character of vegetation, the product of the two sets of figures would be the absolute evaporation. 
 
 Stelling determines evaporation from a combination of yalues which express the amount of 
 vapor in the air corresponding to the temperature of the evaporating surface, the amouftt of vapor 
 indicated by the dew point of the air at the time, and lastly the vapor tension for the existing' 
 wind velocity. To obtain the depth of evaporation by this method would involve the preparation 
 of constants based upon carefiil computations from records for many years. 
 
 Maj. Powell says that 
 
 Kvaporatiou from standing bodies of water will vary from .">!> to Xl> inches per annum, depending upon exposure 
 to winds and upon altitude. The higher the altitude the less the evaporation ; I lie greater the exposure, to wind the 
 greater the evaporation. A large' stream may come from the mountains of Colorado which may lie lost before it 
 rear he- the ( 'olorado Kansas line, and no water whatever pass beyond that line. Out, into the sands on either side 
 the water may run for miles and is rapidly evaporated. What is not lost by evaporation disappears by infiltration. 
 
 In further lest imony on this subject before the Senate Committee 011 Irrigation and Kecla 
 mat ion of Arid Lands, Powell says that 
 
 From waters flowing from irrigated land about, 30 per cent is evaporated. Growing plants evaporate 300 times 
 their own weight of growth annually. \Vhatev er I he crop may lie. whet her corn, grass, or wheat, that grows in one 
 year, it will evaporate :MKI limes its own weight of water. If, then, a crop is raised on a field which is irrigated 
 and a farmer is careless to such an extent thai the field is covered not only with the corn or other crop he desires to 
 raise, but also with a dense growth of weeds, the evaporation from that surface will be enormous. Hut if his field 
 of corn is well cultivated, and if speedily after each irrigation he turns, with a harrow or raking tool, the ground 
 bet ween I he rows, so as to have the ground mulched with a thin surface of soil, the evaporation is at a minimum. 
 
 ('apt. Diilton. of the IJ. S. (Jeological Survey, says: 
 
 Hie e\lcul of evaporation is always in proportion to the surface, other filings being equal. \Ve consider that 
 evaporation depends on three <|nantities: The first is the f einperal urc of the water: the second is the absolute 
 humidity of the air. There, is still a, third, the, rate at which the wind is blowing, the wind factor being really the 
 most important .ni.l the most difficult to handle. 
 
 Tate established by careful experiments the following laws of evaporation in 1862: (1) Other 
 things being the same the r.ite of evaporation is nearly proportional to the difference of the, tem- 
 perature indicated by the \vet and dry bulb thermometers, (li) Other things being the same 
 the augmentation of evaporation, due to air in motion, is nearly proportional to the velocity of the 
 
20 CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 
 
 wind. (3) Other things being the same the evaporation is nearly inversely proportional to the 
 pressure of (he atmosphere. 
 
 Observations show that one third of the water falling in the Seine is taken by that river to 
 the sea. the balance passing oil' by evaporation and percolation. A measure of flic exfeni of 
 evaporation over any region is indirectly given by the flowing waters of rivers and all other 
 streams, which represent substantially the amount by which the precipitation exceeds the evapo- 
 ration, less a small amount permanently lost by infiltration. 
 
 Irrigation will diminish the inflow to lakes, ponds, and rivers, but increase the active area of 
 evaporation. 
 
 Clarence King found an observed evaporation of one-half inch per day in the (Ireat liasin 
 during the dryest period of the year. Anstead gives the same rate of evaporation for the lied 
 Sea during the summer. 
 
 Prof. Russell found the observed evaporation at Keeler, CaL, for the year ending .June .">0, 
 1888, to be 100.6 inches; Fort Grant, Ariz., 101.12 inches; Yu ma, Ariz., i)5.7 inches, and Fort 
 Davis, Tex., 96.4 inches. Bergland gives the annual evaporation at Cumana, Vcne/ncla, as 130 
 inches, and the Dead Sea, 96. Moncrief reports the annual evaporation at Madrid as 05 inches, 
 which corresponds very closely with the rate of evaporation in the California valleys. 
 
 The total precipitation of any region is carried away by evaporation, surface and underground 
 drainage, and underground storage, and the only means of regaining it, except from the clouds, 
 is by the development of an artesian supply and thus increase the total amount of water available 
 for irrigation. 
 
 From what has already preceded we find that the relation of drought to evaporation is most 
 intimate and important. So strong is the agency of evaporation in this respect that we, might, 
 conceive of a region where the prevailing climatic conditions were such as to make the occurrence 
 of drought entirely independent of rainfall. That is, no matter how great the. precipitation, oppor 
 t unities for evaporation would dispose of all the water on the surface not lost by infiltration. It 
 can not be said that any portion of the United States (a region where the average annual rainfall 
 varies from less than 1! inches to over 100) is absolutely free from the occurrence of such a deli 
 ciency iii rainfall and such an excess of evaporation as to result in injury to vegetation and 
 animal life. The same may be said of British India, where the average annual rainfall varies from 
 about 10 inches to 500, but where the density of population is many times greater than in the 
 United States. 
 
 Where the average annual rainfall is over 40 inches there are times when irrigation becomes 
 necessary, especially under abnormal conditions of evaporation. 
 
 Moncrief, in his work on irrigation in southern Europe, cites cases of the employment of 
 irrigation where the annual rainfall was about 40 inches. Similar cases may be found in the 
 United States when systems of irrigation become better understood and more readily applied, 
 and their advantages fully appreciated in the protection of crops. Where the annual rainfall 
 equals or exceeds 40 inches the average cloudiness is Sufficiently high to place a decided check 
 upon evaporation, and therefore a large amount of moisture is saved to the soil and vegetation. 
 By reference to Appendix No. 83 it will be seen that evaporation in the Dakotas is least in the, 
 lied River Valley and is greatest in the Missouri Valley. The values of average cloudiness given 
 in Appendix No. s."> show that the largest region of high percentage embraces the Red River Val- 
 ley and eastern South Dakota. Another very important point to be noted in this connection is 
 the fact that the greatest average cloudiness in the Red River Valley and in eastern South 
 Dakota occurs during the spring and autumn, when crops need most protection from evaporation 
 and plenty of sunshine during the wet and growing season. 
 
 Many cases can be cited of remarkable evaporation under the influence of peculiar winds. 
 
 liefening to the occasional "hot northers" of the California valleys, Abbot Kinney says: 
 
 Orchards planted along the edge of the Sierras, and also the cultivated area planted up to and during 1880, 
 suffered a great deal from the hot, dry, desert winds. I have seen the bark of the trees and the fruit frequently 
 excoriated by the sand carried by the wind, so that the tree and fruit gave the appearance of having been subjected, 
 on the windward side to asand blast. The hot desert winds have been undoubtedly lessened in force iu our valleys, 
 and so also have what we call trade winds. 
 
CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 21 
 
 The Chinook winds of the Northern Plateau and Saskatchewan Valley are attended with 
 remarkable excesses of temperature and evaporation. During the, prevalenceof these winds, which 
 occur most frequently in winder and spring:, the thermograph records at wea..ier bureau stations 
 show almost a vertical ascent of the pen tracing to the extent of from 40 to 50. Reports show 
 that an increase of 70 to 80 in six to eight hours is not, unusual. At Fort Assinaboine, Mont., 
 during the prevalence of a remarkable Chinook wind on January 19, 1892, the thermograph 
 record exhibited a rise in temperature of about 42 in fifteen minutes, and of about 49 in less than 
 three hours. The Fovhn of Switzerland is a hot, dry wind, peculiar to the mountains and val- 
 leys of that country, and during its prevalence remarkable rises in temperature, take, place, 
 attended with an astonishing rate of evaporation. The southeast trade which descends the west- 
 ern slopes of the Andes from the pampas of Brazil, becomes such a dry wind over Peru that 1'res- 
 cott says the ancient Peruvians preserved their dead by exposing the bodies to its action. The 
 northwest anti-trade of New Zealand becomes a hot, dry wind when it crosses the mountains, and 
 its evaporating power is very great. The southeast trade on ilie African coast, and in Sicily, 
 called the Sirocco, is attended with very high temperatures and causes great injury to vegetation 
 by evaporation. Scott says that the Tlarmattan of the west coast of Africa is a hot, east wind, 
 which coming off the desert brings with it clouds of reddish dust which cover the sails and decks 
 of ships far out in the, Atlantic. In Egypt the hot winds from the desert known as the Khamsin, 
 or "fifty," from the idea that it blows for that number of days, causes much damage to ve^eta 
 tion by an excess of evaporal ion. The Zouda, the northeast trade of Argentine Republic, and 
 called the Sirocco of South America, prevails during the months of July, August, and September, 
 generally beginning about 8 a. m., and continuing until sundown, during which time "the heat, 
 is almost suffocating and the air is a cloud of dust," says Mr. E. L. Baker, United States consul, 
 I.nenos Ayres. The Zonda, however, is always followed by a south wind, which at once causes 
 a sudden fall of the temperature, and reestablishes the atmospheric equilibrium. 
 
 .M. Perez, United States consul, Cadi/, Spain, says: 
 
 An si^fiit wliidi considerably modifies the damp character of the climate of northern S]tnin is the peculiar 
 south wind of Ilial. region. It acts like an enormous sponge to absorb the humidity, and us a natural stove where 
 botli Hit- air and the soil are speedily dried up. The atmosphere acquires then such transparency that scarcely any 
 gradual lines or shadows of varying distances on the horizon are perceived. It is peculiar to the south wind that 
 immediately it ceases to blow it is generally followed with rain and that while it is blowing on the coast rain will 
 most likely be falling on the elevated plateau of Old Castile. The winds which prevail longest in the year come 
 from the west-northwest, succeeding the periods from the south. 
 
 The dry, hot southerly winds of the Dakotas, which we will call Hot Southers, are attended 
 with extreme heat and a high degree of evaporation, the extent of which has never been 
 accurately measured. The destructive effect upon vegetation, however, is well known. The 
 occurrence of the Hot Souther is mostly con lined to late summer and autumn, except when abnor- 
 mal deficiencies in precipitation occur earlier in the year. It is important to note, in connection 
 with the occurrence of these high-power evaporating winds, that they result from peculiarities in 
 the distribution of atmospheric pressure, modified to a certain extent by both general and local 
 topography. 
 
 A marked deficiency in precipitation over the Dakotas in any month arises whenever the 
 number of low-pressure areas become greatly reduced, or when the majority of them pass eastward 
 north of the forty eighth parallel. The latter condition operates most frequently as the determin- 
 ing cause, and thereby develops a preponderance of southerly winds attended with excessive 
 dryness and high temperatures. Atmospheric circulation in low-pressure areas moves toward 
 the place of least pressure, and vice versa in the case of high-pressure areas. The air drawn north- 
 ward over the Dakotas in low-pressure areas starts with the moisture of the Gulf and adjacent 
 regions to the north, but precipitates the, vapor over the intervening country, getting rid of the 
 water but retaining the heat and obtaining more of the latter as the currents progress northward 
 over the hot plains of Kansas and Nebraska. In the case of high-pressure areas, when the lows 
 pass eastward south of the forty-fifth parallel, they, the highs, start southward with the cold and 
 dryness of the interior of British America and give the Dakotas the benefit of "first choice," the 
 intensity of the disturbances becoming ameliorated as they progress to lower latitudes. 
 
22 CUllTAIX CLIMATIC FEATURES OF THE TWO DAKOTAS. 
 
 Under such distribution of atmospheric pressure the Dakotas are frequently subjected to 
 extremes <>f cold, heat, and aridity, according to the latitude and velocity of the progressive 
 movement of the disturbances. As these conditions of occurrence depend upon fundamental and 
 general changes in the atmosphere over extended regions of country, and as it is generally 
 accepted that permanent climatic changes are not taking place, it must be conceded that the pre- 
 vailing characteristics of atmospheric pressure over the Dakotas, as shown by the records in this 
 monograph will continue in the future as they have occurred in the past. 
 
 The conditions under which abnormal cold weather, warm weather, dry weather, and wet 
 we.ii her are developed in the Dakotas are shown in Appendices Nos. 21 to 2(5, inclusive, ami in 58 
 to (51, inclusive. 
 
 As to protection from the deleterious influences of evaporation, Prof. Fernow says: 
 
 Summer and winter drought, viz. rapid evaporation, is the bane of the farmer mi Hie plains, ami this is due 
 to the continuous dry winds, which can be checked by rationally disposed timber belts. Another merely mechanical 
 influence which needs no argument or discussion with the observer of natural phenomena, is lhat which the forest 
 cover oil the mountain sides exerts in retarding the melting of the snow anil the drainage of the water, thus prolong- 
 ing tlie period during which the same may be made available. Complaints that the snows do not lie as long into I he 
 summer as they used to, before the forest cover was removed, may be heard all along the eastern Colorado slop,-, 
 where irrigation has been practiced in the most rational manner and the water flow the best observed. 
 
 Absence of precipitation does not always mean drought, especially when the soil is moist and 
 evaporation is retarded by cloudiness and unfavorable wind conditions. Therefore the maximum 
 period without rainfall, as a measure of the intensity of the drought must be considered accord- 
 ingly. In Appendix No. 82 are presented data from a long series of years expressing the drought 
 period as measured by the total absence of rain, for the longest consecutive period, also by that 
 absence plus the time during which there were but "traces" of precipitation, which could have 
 little or no effect upon vegetation. A comparison of the records from North Dakota and South 
 Dakota show that the former is subject to the longest average consecutive period without rain, 
 about 23 days, the extremes varying from 22 days (September to May, inclusive, 1874, 1884, 1890) 
 in the lied River Valley to 45 days (January and February, 1877) in the James River Valley, and 
 54 days (Aiigust to October, inclusive, 1883) in the southeastern portion of the Missouri Valley, to 
 59 days (January to March, inclusive, 1877) in the northwestern portion. In South Dakota the 
 average consecutive period without rain is about 19 days, the extremes varying from 19 days 
 (September to November, inclusive, 1885, 1891) in the Black Hills, to 31, days (( )ctobcr to 1 (ecember. 
 inclusive, 1887, 1888) in the James River Valley, and 45 days (November to March, inclusive, 1804, 
 1887) in the Missouri Valley. Considering the greatest consecutive period without rain, including 
 "traces," the average for North Dakota is about 32 days, the extremes varying from :.".> days 
 (November to January, inclusive, 1885, 1889, 1890) in the Red River Valley to 54 days (February 
 and March, 1880) in the James River Valley, to 113 days (January to April, inclusive, 1880) in the 
 Missouri Valley. In South Dakota the average period without rain, including "traces," is about 
 27 days, the extremes varying from 24 days (January, 1879) in the Black Hills, to.'W days (November 
 and December, 1888) in the James River Valley, to 61 days (October to December, inclusive, 1804, 
 1875, 1880) in the southern portion of the Missouri Valley, and 67 days (February to April, inclu- 
 sive, 1887) in the northern portion. 
 
 The maximum periods without rain are almost entirely confined to autumn, winter, and spring 
 in both Dakotas, and appear to be most frequent from September to December, inclusive, during 
 which latter period the average path of areas of low pressure (storm centers) is north of 1 lie forty- 
 seventh parallel, as will be seen by a reference to Appendices Nos. 155 to 158. inclusive; another 
 striking confirmation of the relation of precipitation and evaporation to the distribution of atmos- 
 pheric pressure. 
 
 A further illustration of this important relation is shown diagrammatically in Appendices 
 Nos. 99 to 138, inclusive, where both the actual and the reduced barometric pressure have 
 been considered, to compare principally, the corresponding effects of the extremes of heat and 
 cold, and the deficiencies and excesses of precipitation. The fluctuations appear to be nearly 
 identical, although perhaps slightly the greatest in reduced pressure, and most marked in both 
 during periods of extremes of drought and excesses of precipitation^the latter being attended with 
 
CERTAIN CLIMATIC FEATURES OP THE TWO DAKOTA S. 23 
 
 the greatest variations. Prof. Hazen has shown from a study of the observations at the summit 
 and base of Mount Washington, for the months of January, February, and March, during a period 
 of sixteen years. 1871 to 1886, inclusive, that the fluctuations of both pressure and temperature are 
 almost exactly identical. ".Occasionally the change in temperature at the summit has preceded 
 that, in pressure to such an extent as to cause the pressure phases to lag behind at the summit." 
 
 In Appendices No. 80 and 81 will be found the normal values of dry periods, excluding "traces" 
 of rain, and including them. These data are computed from a combination of the long and short 
 periods, during a long series of years. Comparing these values with those for cloudiness and 
 sunshine given in Appendices 85 and 86, it will be observed that the normal dry-period values 
 (August to December, inclusive) reach their maximum during the maximum period of sunshine and 
 the minimum period of cloudiness; another confirmation of the influence of barometric pressure on 
 these conditions. Tate says that when the temperature of the evaporating surface is higher than 
 that of the surrounding air the resulting ascensional current of vapor will facilitate the process of 
 evaporation only during continued sunshine. In the case of heavy cloudiness the temperature 
 of the evaporating surface is lower than that of the surrounding air, resulting in little or no 
 ascensional current of vapor and a retardation of evaporation. 
 
 Comparing the normal values of sunshine, cloudiness, and dry periods with the average hourly 
 velocity of the wind (see Appendix No. 87) we find the maximum value of the force occurring 
 from September to April inclusive. The highest of the average maximum -wind velocities (see 
 Appendix No. 90) occur also from September to April inclusive. 
 
 Secular change in precipitation, as shown in Appendix No. 14, appears to afford some evidence 
 of a regular recurrence of eleven-year periods of excess and deficiency in the Dakotas. Perhaps 
 failure to satisfactorily establish such periods may be due, in a measure, to broken records and 
 want of a longer period of continuous observations. Considering the whole territory together, we 
 find an eleven-year period of excess from 1875 to 1885 inclusive, which is also fairly well marked 
 at some of the stations of longest record. If the records at Fort Randall, S. Dak., were complete 
 for the years 1864, 18(>.", isoo, they might show an eleven-year period of deficiency in precipitation, 
 ending with 1874 and immediately preceding the eleven-year period of excess, just referred to. 
 During these missing years there was a rather marked deficiency of rainfall, especially in 18C6, at 
 Fort Abercrombie, N. Dak.; but this would hardly justify the assumption of a deficiency at Fort 
 Randall, particularly as in 1807 and continually thereafter to include 1870, a marked excess in 
 rainfall was reported from Fort Abercrombie, during which time marked deficiencies prevailed at 
 Fort Randall. The records at Fort Randall, which are complete from 1857 to 1891 inclusive 
 (except 1804 to 1866 inclusive) show a twelve-year period of excess (except a deficiency in 1884) 
 from 187.") to 1886 inclusive. 
 
 The combined records for both Dakotas show a thirteen-year period of deficiency (except an 
 excess in 1872) from 1862 to 1874 inclusive. A twenty-year continuous record at Fort Totten, N. 
 Dak., shows an eleven year period of excess (except deficiencies in 1884 and 18S6) from 1S77 to 
 1887 inclusive. A twenty-three-year continuous record at Fort Sully, S. Dak., shows an eleven 
 year deficiency (except excesses in 1883 and 1885) from 1880 to 1891 inclusive. An eighteen-year 
 continuous record at Yankton, S. Dak., shows a thirteen-year period of excess (except deficiencies 
 in 1879, 1880, 1882, and 1884) from 1875 to 1887 inclusive. A twenty-one-year record at Fort 
 Buford, N. Dak., shows a thirteen-year period of excess (except deficiencies in 1882, 1883, 1884, 
 1886, and 1889) from 1879 to 1891 inclusive. A seventeen-year continuous record at Bismarck, N. 
 Dak., shows an eleven-year period of deficiency (except excesses in 1882, 1884, and 1891) from 1881 
 to 1891 inclusive. A fifteen-year record at Fort Abraham Lincoln, N. Dak., and a sixteen-year 
 record at Fort Pembina, N. Dak., are too much broken to be considered independently. The same 
 may be said of a twelve-year record at Fort Sisseton, S. Dak. The six-year record at Fort Rice, 
 N. Dak., has not been used in computing the mean annual deviations for obvious reasons. 
 
 Blauford sought to establish the occurrence of an eleven-year cycle in the Caruatic rainfall of 
 India, from 1864 to 1885 inclusive, through the intervention of harmonic analysis to secure greater 
 precision in the character of the periodical fluctuations than appeared on the face of the records, 
 
24 CERTAIN CLIMATIC! FEATURES OF THE TWO DAKOTAS. 
 
 but without success. General Straehey. in criticism of this method (Nature, July 21. 1887), set 
 forth the statement that 
 
 Such ;i scries of calculated values has no physical signification whatever. The greater or less degree of differ- 
 ence between the observed and calculated quantities only indicates how far the sums of the terms of the harmonic 
 series employed coincide with the series of observed quantities, which the calculated series was designed to repre- 
 sent. The mean variation of the series of observed values, from the mean of all of them, will, of course, lie greater than 
 the mean variation of those observed values from a scries deliberately calculated so as to correspond with them, such 
 as that obtained by aid of the harmonic scries. 
 
 Mr. Elan ford shortly after admitted the correctness of the above criticism. 
 
 Considering all of the annual deviations of precipitation lor 1891 collectively, as shown in 
 Appendix No. 14, for each State, the data would appear to indicate that North Dakota is entering' 
 upon a period of excess, beginning with that year. The same, can be said of South Dakota, but 
 to a less degree, the excess for 1891 being about four-fifths less than in the case of 'North Dakota. 
 On the contrary, during the period of thirty-one consecutive years from 1JSC1 to 1891, for North 
 Dakota, and during a period of thirty-two years from 1857 to 1891 inclusive. (18G4, 1865, and 1866 
 missing) for South Dakota, the former shows an absolute excess about one-third less than appears 
 for the latter. In other words, South Dakota seems to show the greatest tendency to a period of 
 excess from and after 1891. 
 
 The mean annual deviation of precipitation for the Dakotas is about 22 per cent, for North 
 Dakota about 23 per cent, and for South Dakota about 21 per cent. Blanford has shown that in 
 British India severe droughts occur in regions where the mean annual rainfall is less than 50 inches 
 with a mean annual deviation of more than 12 per cent. The ravages of drought in any region 
 must depend very largely upon the density of population. Therefore drought in India or China 
 becomes severe with a much larger rainfall and a much smaller variability in precipitation than 
 in any portion of the United States. It must be admitted, however, that with a mean annual rain- 
 fall of about 20 inches and a mean annual deviation of about 22 per cent the conditions appear 
 to be favorable for the frequent occurrence of drought in the Dakotas, being most marked in 
 North Dakota and in the central and northwestern portions of both States. The least mean 
 annual deviations are found in the Black Hills and in the Red River valley. 
 
 Capt. Wheeler, in his report upon the U.'S. Geographical surveys west of the one hundredth 
 meridian, says that 
 
 While farming without irrigation may doubtless "be safely carried on where the rainfall exceeds 20 inches, 
 yet for the whole interior basin, and indeed for much of the western mountain legion, especially that part south of 
 the fortieth parallel, and particularly not including the more humid northwest, crops may be at least doubled from 
 its use and ordinarily the soil be fertilized from silt deposited. A rainfall of from 12 to 14 inches, properly distrib- 
 uted, would produce cereal crops without irrigation, while in the case of a much greater precipitation, recurring 
 irregularly, it would be requisite. As a rule irrigation implies that the increased production results from a lesser 
 area than that whereupon the necessary amount of rain utilized actually falls. 
 
 A study of secular changes as shown in Appendix No. 14, and of the general distribution of 
 precipitation as exhibited in the various charts, diagrams, and tabulations of this monograph, 
 seem to warrant the belief that no important climatic change has taken place in the Dakotas 
 during the past forty years, or is likely to occur in as many years to come. Local a?id temporary 
 changes, effected through the employment of systems of irrigation and reforestation, are not con- 
 sidered in the above statement because independent of it. 
 
 Mr. C. W. Hall, of Dickey County, N. Dak., testified in 1889, before the Senate Committee 
 on Irrigation and Reclamation of Arid Lauds, as follows: 
 
 This is the driest year we have had for eight years. My acquaintance with this part of the country commenced 
 in August, 1881. In that year the condition of the country was very much the same with regard to drvness that it 
 now is. The Cottonwoo/1 was dried up and only some of the lakes remained full. In 1881 and in 1X82 there was an 
 immense fall of snow, and the next spring the country was full of water and the crops were the. liesl that were ever 
 known in that section. But since that time the country has dried up. At times the whole country will get wet 
 through and then it will gradually dry up. 
 
 Mr. L. R. Casey, of Jamestown, N. Dak., testified as follows: 
 
 Farming in Dakota was begun in 1875 by a few venturesome parties in the Re'd River Valley, but it was 1878 
 before confidence was established in Dakota sufficient to induce emigration to North Dakota. In ten years, from 1877 
 to 1887, the population of Dakota as a whole increased from less than 100,000 to (something over 000,000. Of that pop- 
 
CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 2f> 
 
 ulation North Dakota in 1877 had not more than 20,000. In 1887 it had about two-fifths of the -whole. The basis of 
 that large emigration to North Dakota was the great success of cropping lands, and the emigration to the country 
 was almost entirely east of the one hundredth meridian. That success continued until 1883. During that summer 
 the precipitation was deficient. For the year it was about as usual, but while in other years there had been good 
 rains in June or July, that season it was not so. And in every year when there has been such lack of rain, crops 
 have not been so good. In the year 1886 there had been scarcely any rainfall in the first part of the season in North 
 Dakota. The crops were languishing and discouragement began to come over the people. On the 3d day of July 
 there was a copious rain, lasting fifteen or twenty minutes in the James River Valley and for three hours in the Red 
 Hi ver Valley. The farms in the Red River Valley that had been cropped eleven years without rest, the reports show, 
 g-ve larger crops that season than ever before, and it all turned on that great rain of the 3d day of July. 
 
 Mr. A. W. Burt, of Huron, S. Dak., testified as follows: 
 
 I first went to Dakota in the fall of 1881, and moved there to live in the spring of 1882. At that time there was 
 little or no settlement in that conutry. During the winter of 1880 and 1881 there was in that country what might 
 In- 1'iillcd an abnormal snowfall. That snow melted and filled all the lake-beds and low places with water. During 
 tin- summer of 1882 we had frequent and heavy rains. That season, what little crops there wen: became fully matured 
 ami were good. The vegetables of every description grew to mammoth size. We were all well satisfied that the 
 soil of Dakota was very fertile. In 1883 it was a drier season; still we had plenty of moisture on the surface, and 
 good crops. The summer of 1884 came, and it was <lrier still, and since that time it has continued to grow drier until 
 the supply of water obtained iu 1881 and 1882 became exhausted. The soil of Dakota is black and from 1C to 20 
 inches deep. Underneath this, esperiallv in the central portion of the Territory, lies a bed of red clay, hard and 
 almost impe.rvious to water. When the water falls upon the, surface it penetrates to this subsoil and is held there, so 
 tliat when the rains are over vegetation may draw from this supply. The only thing is to get the water into the 
 ground. We of Dakota dislike to have our country referred to as an arid country. We have always insisted that 
 we had one of the grandest countries in the world, yet to-day, while still clinging to that belief, we must admit that 
 the farming of that country is substantially reduced to a question of luck. 
 
 As to the occurrence of permanent changes in climate, Prof. Upton lias shown from a study 
 of long meteorological records in Xew England that great fluctuations occur in different years, 
 with some indications of periodicity, but no progressive change. The universal popular belief that 
 the climate is changing can only be explained by the short and defective memories of people who 
 recall a few seasons only and who exaggerate the frequency of some special event; by the fact that, 
 the fluctuations are large and often in the same direction for several successive years, or by the 
 difference between the impressions of the child and the adult. 
 
 Mr. Gannett has compared the observations from twenty-six stations, covering periods of from 
 six to twenty-six years, for the western and northern plains, and found some show of an apparent 
 tot al increase of GO inches of rainfall, or a mean of 0.40 inch per year. Other series of observations 
 were compared, of from ten to forty years, in the Central States and in New England, in con- 
 uectiou with the influence of forest areas, and it was found that any difference in the amount of 
 rainfall, as affected by the forests, was too slight to be of material importance. 
 
 Schott has shown, in Smithsonian Contributions to Knowledge, Atmospheric Temperature, 
 and Atmospheric Precipitation, that 
 
 There is nothing in the meteorological curves to countenance the idea of any permanent change iu the climate 
 having taken place, or being about to take place, in the last, ninety years of thermouietric records, the mean 
 temperatures showing no indication whatever of a sustained rise or fall. The same conclusion has been reached in 
 the discussion of the secular change in rainfall, which appears also to have remained permanent in amount as well 
 as iu annual distribution. 
 
 While there appears no important change in the amount of precipitation over the Dakotas, 
 from an examination of the longest record, yet the inhabitants of both States report from various 
 sections evidences of a gradual diminution in the amount of rainfall, by the drying up of lakes, 
 ponds, rivers, and the failure of crops. 
 
 Mr. W. N. Potter, of Lamoure, X. Dak., testified before the Senate Committee on Irrigation 
 and Reclamation of Arid Lands, 1889, as follows: 
 
 Six years ago sloughs nearly impassable by teams were scattered in a majority of the townships, but they are 
 now all dry. The Twin alkali lakes, 3 miles from the town of Lamoure, nearly 2 miles north and south and 
 from 10 to 12 feet deep now one is dry and the other nearly so. Cottonwood Lake, 1 mile long and one-half mile 
 wide, 9 miles southwest of Lamoure, is now a shallow pond 6 feet lower than it was live years ago. This is about 
 all the surface water except the'james River in the entire 1,152 square miles of the county. The James River has 
 been only a shadow of its former self most of the time during the present season. The disappearance of these pomls

 has been gradual, more or less from year to year, in ilie face of the generally received theory that cultivation of the 
 land increases rainfall. Probably the cultivation of the surface, has one eii'ect, viz, to arrest the, falling water before 
 it reaches the water courses. At the. same time it is evident that the supply has diminished and that our farmers 
 have been suffering more and more from year to year. What is true of Lamourc (loiintyin these respects is also 
 true of nearly all the present occupied portion of -the two Dakotas. 
 
 These evidences as to the disappearance of shallow bodies of water and the drying up of the 
 ground are not necessarily indicative of the actual falling off in the amount of rainfall over a vast 
 region like the Dakotas. To develop a permanent deficiency in rainfall would require some catas- 
 trophic change iu the atmosphere itself rather than in the surface of the country. If there is 
 really an eleven-year cycle of precipitation in the Dakotas, a continued deficiency for such a period 
 of lime would undoubtedly result in diminishing the amount of surface water very considerably. 
 But as a marked deficiency in rainfall means an excess of sunshine and warm winds, the strongest 
 influence in the disappearance of the surface wafer is evaporation. 
 
 If the amount of rainfall has not essentially varied during a long series of years, then th" dis- 
 appearance of moisture from the soil and of water from the surface must be due to some modifica- 
 tion of that land surface which accelerates evaporation. It is not improbable that the cultivation 
 of the soil in the Dakotas has hastened evaporation, and it maybe that the disappearance of 
 the moisture has been largely influenced by the character of the soil, which is a black loam that 
 very readily absorbs the heat. Before cultivation, the, hard prairie sod sheds the rain like a 
 duck's back," the water running oft' rapidly and gathering in the nearest depressions, keeping the 
 ponds, lakes, and rivers well supplied. With the advance of the conditions of civilization, extend- 
 ing farther and farther westward the limits of agriculture, decided and permanent modifications 
 have been made of the sin lace, of the country, which have increased the opportunity of the soil to 
 absorb the rainfall and at the same time to give it off gradually to the atmosphere through the 
 process of evaporation. Tlfcsc changes have taken place most decidedly where, the primitive con- 
 ditions of the country have been most completely modified by changes incident to settlement. 
 
 Prof. Fernow says: 
 
 It can no longer be doubted that while, the destruction of forests was the chief agency, yet the pastoral huhil nf 
 the people of western Asia and other oriental countries, once so fertile but now so barren, was one importiinl factor 
 in producing the present dry and barren condition of those countries. Xo country in the interior of a continent, 
 unless supplied with numerous lakes, or numerous and permanent rivers, can remain permanently fertile and pro- 
 ductive if given up largely to pasturage of sheep, gouts, and cattle, without cultivation. The rapid destruction of 
 mountain forests and pasturing their slopes and bordering plains will most certainly have a tendency to render that 
 portion of onr country mure dry and barren. 
 
 Mr. Tate says that 
 
 The rate of evaporation from different substances mainly depends upon the roughness or inequalities of their 
 surfaces. Evaporation is must rapid from the roughest or most uneven surfaces. In fact, the best radiators of beat 
 arc the best vaporizers of moisture. 
 
 The loss of moisture would appear to be greatest from water in commotion than when the 
 surface is quiet; from cultivated land than from unbroken sod; from soil frequently cultivated 
 I han from that occasionally so; from bodies of water exposed to the winds than when protected 
 by forests. 
 
 Capt. Twining, as chief astronomer of the Northern Boundary Survey, 1872 to 1876, states in 
 his report that 
 
 The streams between the valley of the Red River and the Rocky Mountains, excepting only the mountain tor- 
 rents llo wing to the north into the How River and thence into the Saskatchewan, are merely prairie, streams, to which 
 the name "river'' is only given by sufferance. Many of them are most insignificant of rivulets, which, during the 
 melting of snows in the early spring may carry a reasonable volume of water, but in the summer consist, for the 
 most part, of a series of pools, more or less stagnant, and with no appreciable current. The Mouse River and the 
 Milk River are the most considerable of those along the northern boundary, and may be taken as a type of all the 
 prairie, streams of Dakota and Montana. Tints, the Mouse River, though having a length of a,s much as 400 miles, 
 and draining the eastern slope of the Coteau of the Missouri, from north of Woody Mountain to the bend of the 
 .Missouri below Fort Stevenson, yet carries an insignificant volume, of water, being reduced to almost nothing during 
 August ami September. In like manner, the Milk River, rising near tin- Rocky Mountains, ceases to flow during the 
 month of August. As these rivers are not fed by springs, the lack of rain and the rapid evaporation reduces the 
 volume of their flow in proportion to the distance from their sources. 
 
CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 27 
 
 Prairie tires are, without doubt, a considerable detriment to the agricultural development of 
 the Dakotas because of augmenting the influences of evaporation. They appear to occur most 
 frequently in autumn when the atmospheric conditions are most favorable for the loss of mois- 
 ture from the soil, and to the occurrence of drought. Capt. Twiniug refers to these tires in Sep- 
 tember, 187:5, as follows: 
 
 The prairie tires, which for some days had been buruing brightly in every direction, had swept every vestige of 
 grass from these plains, except ill the immediate vicini-ty of the ponds, leaving the ground covered willi a light film 
 of ashes. Our march from this point was most distressing, owing to this cause. A strong east wind raised the dust 
 and ashes in clouds, filling the eyes, nose, and mouth with an irritating alkali which bit and smarted with undying 
 zeal. We reached Fort Totteii on the 20th of October. 
 
 The Monthly Weather Review of September, 1890, refers to prairie and forest fires as follows: 
 
 In the region about Etta Mine, southwest South Dakota, and Bismarck, prairie and forest fires caused wide- 
 spread damage. 
 
 Iii September, 1891, as follows: 
 
 On the 17th and 18th extensive prairie fires were reported in parts of North Dakota, near Rapid City, S. 
 Dak., and in the northern portion of South Dakota. 
 
 The lapse of time and the many changes consequent upon advancing civilization seem to hnve 
 little effect upon this element of danger to the agricultural interests of a vast territory.

 Surrtiilii-i; 1XS6. The following extracts are from a report prepared by the observer, Signal Service, St. Paul, 
 Minn., on the' drought which has prevailed throughout the Northwest during I lie past summer and autumn: 
 
 " The severe drought which has prevailed over the western portion of the country during the summer of 1886 has 
 left its devastating effects on the Upper Mississippi Valley and the Northwest. Its influence was mostly felt in 
 northwestern Minnesota and northeastern Dakota, being most severe and longest in the latter section. Other areas 
 which suffered for shorter periods were northern Iowa, western Wisconsin, southeastern Minnesota, southwestern 
 Dakota, and eastern Montana. 
 
 " This paper will treat mainly on its effects in Minnesota and Dakota. 
 
 " In these States the usual copious rainfall of May was lessened so considerably that the drought literally began 
 to be appreciable in that month. The temperature was abnormally high, with a deficiency in rainfall of nearly 1 
 inch. 
 
 "In the month of June the temperature was about normal, while the precipitation was nearly H inches below 
 the average in Minnesota, and about 2 inches below in Dakota. 
 
 "In July the rainfall continued In-low the average, with the greatest deficiency occurring in eastern Min- 
 nesota and southern Dakota. At Dulutu, Minn., the deficiency was 2.42 inches; La Crosse, Wis., 3.08 inches; 
 Huron, Dak, 3.26 inches; and Yaukton, Dak., 3.28 inches. The temperature in Dakota was decidedly above 
 the normal, at Huron being f>-.-l above, and Bismarck 6 above. In Minnesota it was also above the normal, with 
 the mean temperature of the State 7 C .2, while the average of the minimum temperatures was 50-.5. The tempera- 
 ture was phenomoually high during nearly the entire month, While at Sherbnrne and .Spring Valley the maximum 
 temperature was respectively 107 and 104, which is about the greatest heat ever observed in this State. 
 
 " In August there was an excess of over 2 inches oi' rainfall in the southeastern portion of Dakota, while in 
 northern Dakota and Minnesota the rainfall was below the average: the deficiency being 3.1 inches at St. Vin- 
 cent and 2.5 inches at Moorhead. The temperature continued above the average with the maximum above 100 
 north to St. Vincent, where it rose as high as 103.2. 
 
 September in eastern Minnesota brought an excess of rainfall, while there was a deficiency in western Minnesota 
 and northern Dakota. The temperature, was markedly below the normal at Dnlutli, while it was slightly above in 
 southeastern Dakota. 
 
 "In October the rainfall was slightly below the average, while the temperature was decidedly above. For Min- 
 nesota the mean temperature was 8. 7 above the mean of the corresponding month of 1S85. The greatest depart- 
 ures from the normal were 8 above at Dnluth, 6 above at Moorhead, St. Vincent, St. Paul, and Vankton, and 5 
 above at Huron. 
 
 "Pastures became burned and brown early in the season and caught lire readily from sparks of passing trains. 
 Those crops which yielded fairly well were favored with early rains and were past danger when the dry season be-

 gan. Tin" effect on iiewiv seeded grass fields has been unusually severe, in many ruses rendering the seeding of 
 t-arlv spring worthless. Tree seeds in northern Dakota have become very scarce and are in great demand. 
 
 "Sloughs, lakes, and rivei-s, which had the appearance of having been in existence for ages, have become dry, 
 leaving the alluvial soii found in their bottoms to be baked by the burning sun, thus causing it to be cracked over 
 an inch wide and many inches deep in Nome, localities. Regions where there was but a thin layer of soil upon a 
 gravel or stone bottom suffered far more from the drought than those favored by ground of clay formation. 
 
 "Prairie fires were much more frequent and did greater damage than in previous years. The removing of the 
 grass covering from the earth by these tires exposed its surface to the direct rays of the sun, thus allowing undue 
 absorption of the moisture from the soil and leaving it in a dry condition. In localities well favored with forests 
 the tli'eets of the drought were largely modified and showers were generally more frequent, thus showing the great 
 necessity of protecting those woodlands which so materially assist in moderating droughts and floods. Rain was 
 also more frequent near large bodies of water and along large streams. 
 
 "During the fall of 1885 and winter of 1885 and 1886 the fall of snow and rain was very light, and was followed 
 by a summer marked by a decided deficiency of precipitation, which had the effect of drying sloughs, hikes, and 
 rivers to an almost unprecedented extent, causing the ground in many localities to be as dry as dust to the, depth of 
 8 or 9 feet. This, together with the lack of water all through the West and Northwest, could supply the at- 
 mosphere with but little moisture to be precipitated. The universally high temperatures which prevailed added 
 very materially to the injurious effects of the dry weather. 
 
 " Were it not for the great number of lakes found in this region, there being 7,000 to 10,000 alone iu Minnesota, 
 with an average of S'20 acres and upward, and the forests and woodlands which cover one-third -of the Stale, tin-re 
 is no doubt but that the damage would have been far greater. 
 
 "In some localities there seems to be a period of increase and decrease in the ai mt of water in lakes and 
 
 rivers, while in other localities there seems to be a yearly decrease in the amount of water. 
 
 "In Minnesota the drought began in May and ended in August, ami September in the, central and southern poi 
 lions, while in the .northern it continued quite severe until November 1. In length it ranged from forty-one da_\s 
 in the southeastern portion of the State to over five mouths in the northern portion. 
 
 ******** # * * * 
 
 " In Dakota the drought began generally during the latter portion of June and was still existing November 1. 
 It seemed more severe in the western portion of the State; Wells and Stark counties reported the rainfall to be far 
 below the average since July, 1S85. The State has also suffered severely from prairie tires, which devastated vast. 
 tracts of land; in the northern portion of the State forest fires have done, irreparable damage. In some portions of 
 the State trees planted several years ago are in a flourishing condition, showing that t imber can b grown ami \\ill 
 prove valuable both as a commercial article and as an assistant preventive of drought."

 General remarks on drought of past six months: The very serious drought which prevailed from May to Sep- 
 tember in Michigan, Wisconsin, Iowa, Ohio, Indiana, Illinois, Kentucky, and Missouri was slightly ameliorated in 
 northern Wisconsin during October, but the condition of affairs at the end of the month was still serious, as appears 
 from extracts elsewhere. The commencement of this drought was in April last, during which month less than .">() 
 per cent of the average precipitation fell in southern Michigan and Wisconsin, northern Illinois, the southwestern 
 part of Iowa, and the northwestern part of Missouri. 
 
 During May a precipitation slightly above the average' fell over a holt of country about 60 miles wide, extending 
 from Cincinnati, Ohio, and Frankfort, Ky., westward to Indiana, and Illinois, including the immediate valley of the 
 Missouri River as far as Jefferson City; elsewhere in the States previously named Hie precipitation was largely 
 delicient, especially in Iowa, Illinois, and the northern half of Michigan, where the percentage ranged from 20 to .".(I 
 of the average rainfall. 
 
 In June the area over which less than half the usual rain fell comprised Iowa, Illinois, southern Wisconsin, 
 southwestern Michigan, and northwestern Indiana. Throughout the section named only from one-tenth to one-fifth 
 of the usual rainfall for June occurred in many places. 
 
CEKTAIN (JLIMATIC FEAT[TRES OF THE TWO DAKOTAS. 29 
 
 During July a slight excess of rainfall fell over the northern half of the lower peninsula of Michigan and cen- 
 tral Wisconsin, but throughout the rest of the drought-stric.ken States, the precipitation generally ranged from r>0 
 to 80 per eent of the average, except in Ohio, southern Indiana, southeastern Illinois, the western parts of Iowa, and 
 Missouri, where the amount of rain in some cases was only from !.""> to :!0 per cent of the mean. 
 
 During August slight excesses fell in western Iowa, western Wisconsin, and tin- northern part of Illinois; 
 throughout the rest of the drought district the rainfall was generally from one half to three-fourths of the average, 
 but in the greater part of Michigan, as well as in the, southern part of Illinois, the amount was less than one-half 
 the mean. 
 
 In September the greater part of Iowa, Wisconsin, and northern Illinois, and the extreme southern part of 
 Michigan was relieved by rainfall slightly in excess of the average, but the remaining States still suffered from a 
 deficiency for the month, which in the northern part of Michigan ranged from one-sixth to one-half the usual amount. 
 
 The condition of a Hairs has improved materially in Wisconsin during October, where a slight excess of precipi- 
 tation has fallen. In Michigan, Iowa, the greater part of Illinois, and Indiana the drought is aggravated, as the 
 
 precipitation has only been from ".-third to three-fourths of the usual amount, while in the valley of the Ohio and 
 
 of the Mississippi, from Cairo to (Jnincy, the amount of rainfall has been exceedingly small, not averaging more 
 than 20 per eent for that district and ranging from 10 to SO per cent. 
 
 During the six months from May to October, inclusive, the rainfall has been largely deficient over Minnesota, 
 Wisconsin, Michigan, Iowa. Missouri, Indiana, Illinois, Kentucky, and parts of Minnesota and Dakota, and eastern 
 Nebraska and southeastern Kansas. Less than one-half the usual amount of rainfall during these mouths has fallen 
 in central Ohio and at certain points on the immediate, banks of the Ohio River, from Louisville lo ( 'airo. inclusive. 
 Similar local deficiencies, averaging more than 50 per cent, occurred near Springfield, 111., Webster, Dak., and La 
 crosse. Wis. Less than three-fourths of the average amount of rain has fallen during these live months from Mich- 
 igan, Ohio, and Kentucky westward to include Missouri and Iowa. 
 
 Unless an excess of ra.infa.ll occurs during November these Stales must sutler, owing to the small amount, of 
 water which fell during the first of the season, as streams and wells must fail and the ground itself bo in such a dry 
 condition as to interfere more or less materially with the winter wheat or the early spring crops.

 The. following .statement relative to "the great drought," from 1SS7 to 1891 over the western 
 and northern plains, is extracted from the Sioux City Journal, Sioux City, Imv;i, December, 18!) 1 : 
 
 It may now be said that the great drought, which for several years afflicted the interior of the continent, a, large 
 portion of the Rocky Mountain region as well as the whole Mississippi Valley, has been broken. The extent and 
 severity of the great drought have not been generally understood. 
 
 The drought began as early as 1887 and was not generally chocked till the winter of 1890 and 1891. It reached 
 its climax in the season of 1890, when the wheat crop of the United States was cut down almost 100,000,000 bushels 
 below the preceding year, which latter itself had been greatly shortened by drought; the corn crop, 600,000,000 
 bushels; the oat crop, 230,000,000 bushels, and other great crops, like hay, potatoes, etc., in similar degree. 
 
;}< ) CERTAIN CLIMATIC FEATUEES OF THE TWO DAKOTAS. 
 
 Tin 1 drought was felt through all these years, in varying degrees of severity, from the Gulf const northward over 
 :ill tin- States bordering the Mississippi and Missouri rivers far into the British Possessions. It shortened crops in 
 Illinois and Iowa materially, and it was more severe in Kentucky, Tennessee, and especially in Arkansas and large 
 portions of Missouri. 
 
 But tin-. tierce brunt of the drought fell upon that vast strip of plain country which lies west of the ninety-sev- 
 enth meridian of longitude, including the western two-thirds of North Dakota, South Dakota, Nebraska, Kansas, 
 Indian Territory, New Mexico, and the major portion of Jthe great Stale of Texas. Throughout this region the 
 drought was general, although much more severe in one locality than in another. In extensive areas crops were 
 total failures, and even in other areas which are exclusively devoted to grazing grass was almost burned up and 
 water disappeared. In many places where the Government surveys have marked the mean derings of extensive lakes 
 or marshes, as in some localities in South Dakota, and where such had been known to exist up to 1887, the water 
 tolally disappeared. 
 
 It was the greatest drought which the record of half a century in that region gives any intimation of. There has 
 been nothing comparable with it. Its results were far-reaching. They were the more serious because for a- period 
 of several years prior to 18S7 immigration had been pouring into the region west of the ninety-seventh meridian. 
 Nearly all the settlers were poor, the majority very poor. They had come in quest of Government land, in most cases 
 with barely means more than to effect a settlement. They were borrowers. For a period of several years loan com- 
 panies sold an immense number yf loans on these settlements to people living in all the States to the East, and very 
 largely to people living in New England. The loans went into improvements, into farm machinery, and into other 
 means for cultivating the land. 
 
 Under such circumstances, even if there had not been others to aggravate the situation, a drought extending 
 over a series of years could not fail to be disastrous. Year after year in some localities the settlers suffered total 
 loss of crops and were deprived not only of the means of repaying the money they had borrowed, but even of sub- 
 sistence. At length some became so discouraged as to abandon their settlements. Those who had loaned mone\ to 
 the settlers suffered with them, often neither principal nor interest being paid. It was not understood in the Kasl 
 that an extraordinary drought was in progress, and the country got a hard name, which attached not only to the 
 st ricken districts, but also to regions whore the effect was not so severely felt. Capital .eased to move towards t ho 
 settlers and began to be withdrawn to the extent possible. 
 
 In Missouri, Illihois, and Iowa, and in similar communities, whore for the most part the drought was not so 
 severe, the people, by their longer establish men t and aerunmlat ions, were incomparably bet (IT prepared to end in v 
 it. There were some regions, of course, which were more fortunate than the country -generally. The one which 
 suffered least in the United States was a comparatively narrow belt on both sides of the Missouri River in north- 
 western Missouri and extending north along the boundary between Iowa and Nebraska, gradually broadening to its 
 greatest width, which included the northeastern counties of Nebraska and a number of counties of Dakota and 
 northwestern Iowa, the central point of which is Sioux City. Drought, indeed, shortened crops even here, but the 
 peculiarity of the. soil, the great depth of the line, spongy, friable soil, free from stratilied rocks, greatly modified 
 the injurious ellccls, so that nowhere else in all those years was there so high an average yield as here. 
 
 Outside, of southwestern Texas and extensive portions of New Mexico, this ex t .ra ordinary drought was broken in 
 the winter of 1S!IO-'91. There were copious rains, followed by a heavy, general snowfall, which melted awa\ grad 
 nally late in the spring, Frequent rain showers occurred all through the season, tilling up the old marsh and lake 
 beds. The result was the prodigious crops of every kind which the whole interior of the continent, the legion west 
 as well as the region cast of the ninety-seventh meridian, produced in 1S!H. 
 
 Heavy rains last fall and early in the winter, have not onl\ again saturated the earth throughout the \\Yst. and 
 made absolutely sure a crop this year, hut have also shown that the last vestige of the drought period has disappeared 
 and the West has entered upon a cycle of abundant moisture.

 In the presentation of monthly means and extremes of temperature broken records of a month 
 or mote are given, in addition to those of long and continuous periods of observation. The latter, 
 of course, are, the mote valuable, but within a region of such vast extent as that embraced by the

 dent value to fairly determine a single monthly mean or extreme. In publications of this character 
 it lias usually been the policy to neglect temperature and precipitation values where the records at 
 any station fell short of a complete year. The thirteen charts of monthly and average temperatures 
 have been prepared without the usual employment of isometric lines. The reason for this, as set 
 forth under precipitation (see page 12), regarding the monthly and annual charts of rainfall, will 
 apply in the case of temperature. 
 
 Temperature data are submitted from selected stations (see Appendix No. 41) from regions sur- 
 rounding the Dakotas. especially to the north and south. Comparisons under such conditions 
 serve to disclose some of the peculiarities of climatology characteristic of the Northern Plains. 
 From a study of the distribution of average temperature in the Dakotas, as shown upon the monthly 
 charts, and from an investigation of the distinctive features of thermometrie conditions as exhib- 
 ited by the various tabulations, the follow ing are suuie. of the conclusions and statements which 
 may be otl'ered: 
 
 1. The higher average temperature of (South Dakota, due to latitude and independent of 
 elevation. 
 
 2. The high average temperature of the Black Hills in winter and the low average of summer, 
 as compared with the remainder of South Dakota. This mountain region is protected by heavy 
 forests from the high and dry. cold winds which sweep the more exposed portions of the territory. 
 These differences apply also to the maximum and minimum temperatures, and to the ranges, 
 monthly, annual, and mean annual. 
 
 3. The average, monthly temperature of North Dakota, computed from fifteen stations, ranges 
 from 3" in January to 7(P in .Inly, the extremes varying from 3 at Kichardton and Fort I'embina 
 (St. Vincent, across the river, (>) in January to 71 at Fort Stevenson and 75 at Fort Rice in 
 July. The Red River Valley is both the warmest region in summer and the coldest in winter 
 in North Dakota. The James Kiver Valley comes next, followed by the Missouri Valley. 
 
 4. The average, monthly temperature in South Dakota, computed from eighteen stations, 
 ranges from i:> in January to 72 in July, the extremes varying from 3 at Fort Sisseton and 4 
 at Webster in January to 75' ! a' Fort Sully and 70 at Fort Randall and Vermillion in July. The 
 coldest portion of South Dakota is found in the extreme nort heast and the warmest in the Mis- 
 souri Valley. The extreme eastern portion of the State is colder in winter and spring than in the 
 Black Hills, but much warmer in the summer. The James River Valley is, next after the Missouri 
 Valley, the wannest portion of South Dakota. 
 
 5. North and South Dakota approach within about 1' of each other during t lie summer, but 
 diverge to the extent of 4 to IIP in autumn and winter. North Dakota being colder. In the dry 
 season, October to March, inclusive, they diverge about 7, and in the wet. season, April to Sep 
 tember, inclusive, they are about equal. Considering the dry season to include Sept ember to March, 
 inclusive, the divergence is still 7 "', but in the wet season, April to August, inclusive, they change 
 from equality to a difference of 2. Narrowing down the dry season to tour months, November to 
 February, inclusive, the divergence is still about 7. Extending the wet season to eight months, 
 April to March, inclusive, the divergence increases to about 4. Comparing the wet lest period of 
 the year, May to August, inclusive, the divergence remains steady at about 2. It is then evident 
 that the mean temperature of the dry season is controlled by the four winter months (Novem- 
 ber to February, inclusive), the driest period of the year, and that the mean temperature of the wet 
 season is controlled by the four summer months (May to August, inclusive), the wettest period of 
 the year. (See Appendices Nos. .">, 40, 41, and 54 to 57 inclusive.) 
 
 (i. The mean annual range of temperature in North Dakota varies from 132 at Bismarck to 
 141 at Fort Buford. The extremes vary from IKJo at Fort Buford to 151 at Fort Yates and Fort 
 I'embina, and 154 at Fort Buford. In South Dakota the mean annual range of temperature 
 varies from 116 at Deadwood and 119 at Yankton to 132 at Fort Sully, and 13S nt Webster. 
 
 The extremes vary from lo:-r at Fort Randall and 10<i afc Deadw 1 to 1 4.V at Fort Randall, and 
 
 14(i at Webster. The annual ranges of temperature are greatest in North Dakota, reaching a 
 maximum in the Red River Valley and in the extreme northwest portion. The least ranges are in 
 the Black Hills and the Missouri Valley of South Dakota. Compared with adjacent regions it is 
 found that the district of maximum annual range embraces northeastern Montana and the Saskat-

 c,hcwan Valley. The largest ranges are reported from Poplar River, Mont., 159, Medicine Hat, 
 British America, 158; and Fort Assumiboine, Mont., 157. (See Appendix No. 47.) 
 
 7. The mean monthly range of temperature in North Dakota varies from 47 at Fort Totten in 
 July to 80 at Fort Buford in January. In South Dakota^ the range varies from 45 at Yankton 
 and 47 at Dead wood, in July, to 83 at Webster and 86 at Fort Meade, in February. The 
 monthly ranges during winter are considerably the highest in South Dakota and occur later in the 
 season. (See Appendix No. .48.) 
 
 8. The mean daily temperature ranges are quite uniform in both States and throughout the 
 year. The least ranges are found in the Black Hills with a mean annual of 21, and the extremes 
 varying from 18 in December and 19 in April to 23 in January. Generally the highest daily 
 ranges occur in both States from July to October inclusive, and vary from 20 to 29, the highest 
 being in northwest North Dakota and the lowest in the Black Hills. (See Appendix No. 49.) 
 
 9. The maximum daily ranges of temperature vary in North Dakota from 30 at Bismarck, in 
 .1 nly, to 57 at the same station in January, and 55 at Fort Buford in February. In South Dakota 
 i hev vary from 25 at Deadwood in March and 27 at Yankton in June to 54 at Huron, in De- 
 cember, and 55 at Deadwood in January. (See Appendix No. 50.) 
 
 10. The minimum daily ranges in North Dakota vary from 1 at Bismarck in December and 
 at Fort Buford in May to 18 at Bismarck in June and 21 at Fort Yates in August. In South 
 Dakota they vary from 1 at Fort Sully in December to 13 at Deadwood in June and 17 at 
 Huron in the same month. (See Appendix No. 51.) 
 
 11. The mean daily variability of temperature (the change which takes place in the daily mean 
 temperature from one day to another, independent of increase or diminution of temperature, and 
 the. best test of equability) varies, on the average, in both States from 4 during June to August 
 inclusive, to 9 in January and February. The extremes vary from 4 in the Missouri Valley, ,) line 
 to August, inclusive, to 10 in the Red River Valley hi January and February. (See Appendix 
 No. 53.) 
 
 12. The extreme maximum temperatures in North Dakota range from 101 at Fort Feinbina 
 in August, 1S86, to 110 at Fort Rice in July, 1871, and at Fort Abraham Lincoln in August, 187<i. 
 In South Dakota they range from 101 at Brookings in July, 1888, to 112 at Fort Randall in July, 
 1ST I, Forest City, August, 1891, and Smithville, August, 1881, to 114 at Fort Sully in July, 1S71. 
 In both States, the maximum temperatures rise above 100 from June to September, inclusive, 
 occurring most frequently in South Dakota and in the central portion of that State. The lowest 
 extreme, maximum temperatures are found in the Red River Valley and in the Black Hills. (See 
 Appendix No. (55.) 
 
 13. The extreme, minimum temperatures in North Dakota range from 34 n at Furl Kice. in 
 December, 1871, to 51 at Fort Peinbina in January, 1888, and 51 ! 'at Fort Stevenson in De- 
 cember, 1879, and 55 at the same station in January, 1SS1. In South Dakota Micy range from 
 32 at Deadwood in February, 1883, to 44 at Fort Randall in January, 1875, at Webster 
 in January, 1887, and 45 at Fort Sisseton in December, isso. In both States the minimum 
 temperatures fall below zero from November to March, inclusive. In North Dakota the months 
 of October and April arc included in this record of low temperatures, especially in the Red River 
 Valley. Fort Peinbina, N. Dak., and St. Vincent, Minn., just across the river, are the only 
 stations where the annual minimum temperature falls below zero, the. lowest record being 4 at 
 Fort, Peinbina in 1875 and 1887, and at St. Vincent in 1887. (See Appendix No. (5(5.) 
 
 14. The time of occurrence of first killing frost in North Dakota ranges from August, I 
 (Napoleon, 1890) to September 30 (Fort Buford and Fort Totten, 1884). The t hue of occurrence, of 
 last, killing frost ranges from March 17 (Steele, 1890) to June 24 (Fort Totten, 1887). (See Ap- 
 pendix No. 63.) 
 
 15. The time of occurrence of first killing frost in South Dakota ranges from August 22 (St. 
 Lawrence, Webster, and Woousockct, 181)0) to October 21 (Yankton, 1884). The time of occur- 
 rence of last killing frost ranges from April 7 (Fort Sully, 1888) to June 22 (Huron,* 1885). 
 (See Appendix No. 64.) 
 
 16. The coldest weather prevails in North Dakota and throughout the territory east of the 
 Missouri, the, lowest, average temperatures being reported from the Red River Valley. In summer 
 the Missouri Valley receives the maximum amount of heat.

CERTAIN CLIMATIC FEATURES OF THE TWO DAKOTAS. 33 
 
 17. From an examination of the distribution of temperature over the Northern plains, 
 Manitoba, and Hudson Bay Territory, it is evident that eastern North Dakota lies within the 
 southwest quadrant of the area of maximum cold in the interior of the, continent, and that with 
 northeastern Montana and northwestern Minnesota it forms the region of greatest cold in the 
 United States. 
 
 IS. The marked increase in temperature west of the one hundred and eighth meridian, even as 
 far north as the fifty-fifth parallel, shows the influence of the high northerly path of warm low- 
 pressure areas from the Pacific. These disturbances rapidly diminish in intensity as they pro- 
 gress eastward, reaching the maximum effect in this particular, from loss.of heat and moisture, at 
 about the one hundredth meridian, when they begin to develop renewed energy through the influ- 
 ence of these elements brought by the southerly winds from the Gulf. 
 
 111. The Dakotas, Minnesota, and Montana lie within the region- over which the most pro- 
 nounced areas of high pressure descend from the interior of British America. These highs appear 
 to produce their maximum effect, from the cold, dry air of the upper atmosphere, over the region 
 from Hudson Bay south westward to northern Montana, northern Dakota, and northern Minnesota, 
 and thence eastward north of the forty-seventh parallel. 
 
 20. North Dakota and northeast South Dakota are subjected to the coldest winds, and those 
 of the highest velocity, which tend to remove the snow from exposed and cultivated lands and 
 deprive them of the protection afforded by such a covering. 
 
 21. The distribution of temperature is governed very largely by the distribution of atmos- 
 pheric pressure. Abnormal periods of heat and cold depend broadly upon the average latitude of 
 areas of low barometric pressure in transit over the Dakotas. These facts are graphically set fort h 
 in Appendices Nos. !W to 138, inclusive, and in Nos. 147 to 158, inclusive. The cumulative effect of 
 warm and cold periods, under the influence of the distribution of atmospheric pressure, is graph- 
 ically shown in Appendices Nos. 58 to(il, inclusive. The warm periods for the months of January, 
 1S8!, 1S91, and I'Ybruary, 1880, show a total excess of temperature of over 400. During these 
 months the average latitude of areas of low pressure was considerably north of the forty-ninth 
 parallel, thus bringing over the Dakotas, by means of cyclonic circulation, the warmer air of the 
 Gulf and Mississippi Valley. A corresponding effect from the cold periods is shown for the months 
 of January, iSSIJ. 1S87, and February, 1887, when the total deficiency of temperature amounted 
 to over 400. During these periods the average latitude of areas of low pressure was south of the 
 forty seventh parallel, which had the effect of carrying over the Dakotas, from British America, 
 an abnormal quantity of cold, dry air by means of anti cyclonic circulation. A comparison of the 
 attendant conditions of these warm and cold periods brings to view a remarkable compensating 
 effect iii the annual distribution of temperature and disposes of the theory of permanent climatic 
 changes. 
 
 22. The relation established between the distribution of temperature and tlrat of barometric 
 pressure in the development and progressive movement, of low-pressure areas, as shown by the 
 charts and tables for warm and cold periods (Appendices Nos. .~>S to <>1, inclusive), may be applied 
 to the demonstration of the causes giving rise to the occurrence of any abnormally warm or cold 
 month of tin 1 year. 
 
 23. As to the more remote but yet more important causes, because forming the basis of fore 
 knowledge as to the probable occurrence 1 of warm and cold periods, the study of mean monthly 
 barometric pressure would seem to justify the preparation of the accompanying ideal typical 
 chart. An explanation of the construction of these charts is furnished under the head of "Pre 
 cipitation" (see page 12), where, similar ones are submitted in connection with the forecasting of dry 
 and wet periods. 
 
 A distribution of average barometric pressure, giving rise to the formation of a pronounced 
 HIGH over the Plateau and Rocky Mountain regions, will generally result in diverting the major- 
 ity of the paths of all low-pressure areas to the northward of the forty-seventh parallel and 
 result in carrying over the Dakotas the much warmer air of lower latitudes, giving rise to abnor- 
 mally warm weather. If, on the contrary, the barometric pressure remains abnormally high over 
 Manitoba and Hudson Hay Territory the low-pressure areas are diverted southward below the 
 forty fourth parallel, and the attendant system of atmospheric circulation gives rise to a prepon- 
 S. Ex. 157 5 
 
34 CERTAIN GLJMAT1O FEATUKES OF THE TWO DAKOTAS. 
 
 derance of cold air over Hie Dakotas, with abnormally low temperatures. If, for example, 1 he 
 mean isobars of November develop the warm-weather type, abnormally high temperatures (usu- 
 ally warm days in periods of 2 to 5) may be reasonably expected in December and January fol- 
 lowing. If the type chart appears in January, then the warm periods may be expected in Febru- 
 ary and March. A similar explanation applies to the occurrence of cold-weather types. 
 
 24. The general direction of low-pressure areas over the Dakotas and adjacent regions to the 
 north and south, as illustrated on the Monthly Storm Track Charts, Appendices Nos. 147 to l.">x, 
 inclusive, explain the occasion for the continued alternation of warm and cold periods and the 
 occurrence of extraordinary extremes of temperature. The direction of progressive movement is so 
 nearly due east and west that atmospheric circulation over the Dakotas is practically confined to 
 either northerly or southerly winds. Under such circumstances the tendency to extremes of tem- 
 perature is very strong all <i must result in a peculiar effect upon the industrial interests of the two 
 States. It is hopeless to expect any radical change in the atmosphere itself, but the surface of the, 
 << iinitry in relation thereto, may be modified by cultivation, irrigation, and the growth of forests so 
 :is to diminish the effect of abnormal and destructive weather changes. In the protection of eon 
 siderable areas of land it would appear advisable to plant the trees in comparatively narrow strips, 
 extending east and west. They would not only diminish evaporation from the soil over the pro 
 tected area, and thus lessen the range of temperature, but by interrupting the course of the winds 
 destroy their effect in developing and maintaining extremes of temperature and abnormal evap- 
 oration. 
 
 2.~>. The annual distribution of temperature over the Dakotas, as shown by the records fora 
 long scries of years, a tabulation of which appears in Appendix No. 56, develops no well-estal> 
 lislied cycle, perhaps because the records are not sufficiently extensive and uniform as to the 
 length of the period of observation. From an examination of the annual sums there appears some 
 evidence of the existence of two and three-year cycles of temperature changes, the latter being 
 practically confined to excess of temperature (warm periods) and the former to deficiency of tern 
 perature (cold periods). This results in an apparent increase in temperature in North Dakota of 
 about 2 in the past 30 years, while in South Dakota during the past 33 years the records appear 
 to show a deficiency of about 1. If the records were satisfactory in all respects we might say 
 that the Dakotas have been gradually growing warmer since about 1860, North Dakota taking 
 the lead. The tabulation appears to indicate that the alternation of warm and cold periods is so 
 evenly balanced and of such short duration that all tendency to permanent excesses or deficien- 
 cies is prevented. There is also developed the important fact that the yearly departures are often 
 very sharp and considerable, illustrating one of the characteristic features of the climatology of 
 the Dakotas. 
 
 It is necessary that the climatology of every State, or larger areas having uniform elimat ic con 
 ditious, should be thoroughly investigated and discussed before satisfactory comparisons in impor- 
 tant details, affecting animal and plant life, can be made in a comparative study of the whole 
 country. 
 
 CONCLUSION. 
 
 In a brief summarization of final deductive results the following are submitted as some of 
 the lessons which may be drawn from this investigation: 
 
 1. The Dakotas must resort to an extensive system of irrigation. 
 
 2. Forests must be preserved and extensive reforestation adopted. 
 
 3. Increase the number of rainfall stations and make the reports accurate and continuous. 
 
 4. If there are great local variations in rainfall they should be carefully investigated. 
 
 5. Increase the area covered with vegetation. 
 
 (i. Pursue some method in cultivating the soil whereby the snowfall may be prevented from 
 drifting away under the influence of the winds. Plowing shallow ditches every few rods or the, 
 growing of hedges every few hundred yards might accomplish the object sought. 
 
 7. The distribution of temperature and precipitation in the Black Hills furnishes an instruc- 
 tive lesson as to the. influence of forests on climate. 
 
CERTAIN (JLIMATIC FEATURES OF THE TWO DAKOTAS. 35 
 
 8. The distribution of precipitation throughout the year, while favorable, in a measure, to 
 agricultural interests, is too small in the aggregate to prevent the occurrence of severe droughts, 
 especially in North Dakota and the central portion of South Dakota. 
 
 9. The snowfall is too light and the winds are too heavy to secure from this form of precipita- 
 tion much, if any, protection to crops. 
 
 10. The precipitation of spring and summer compares favorably with the moist regions of the 
 Central .Mississippi and Ohio valleys, but the precipitation of autumn and winter shows a pro- 
 nounced deficiency, which makes the average of these seasons less than in the arid regions of the 
 Middle Plateau. 
 
 11. The geographical position of the Dakotas is such, relative to the path of atmospheric 
 disturbances between the Pacific and the Atlantic^ near the forty-ninth parallel, that no impor- 
 tant permanent change can reasonably be expected in the amount and distribution of their pre- 
 cipitation. 
 
 12. The withering effect of the hot, dry southerly winds may be obviated, in a measure, by 
 spraying plants and trees with water and irrigating the soil beneath them. 
 
 13. The Dakotas lie within what is called the "subhumid region," a mean condition between 
 the arid and moist regions of the country, where agriculture can hardly be conducted without 
 years of drought succeeding years of prosperity, and where irrigation from artesian wells and 
 storage reservoirs must be resorted to in order to tide over the unpropitious seasons. 
 
 14. A careful hydrographic survey of the Dakotas should be made in order to obtain reliable 
 and exhaustive information on the subject of evaporation, in connection with the supply and dis- 
 tribution of precipitation, and the establishment of a satisfactory system of irrigation. 
 
 15. Every feasible means of checking evaporation must be adopted. Wind-breaks of trees or 
 hedges may be employed to this end. Becquerel has ascertained that a hedge 6 feet in height 
 will afford protection to the surrounding soil a distance of 70 feet. Experiments have shown that 
 a narrow belt of trees, every 300 to 1,000 feet, according to the character of the soil and the kind 
 of vegetation, will offer protection from the drying effect of winds. 
 
 16. The meteorological and physical features of the Dakotas are such that under the influence 
 of settlement and the consequent development of agriculture changes are effected which tend to 
 the rapid dissipation of the moderate rainfall, through absorption and evaporation. Irrigation 
 and reforestation are the only remedies. 
 
 17. The creation of lakes, ponds, and rivers in the Dakotas, with the expectation of thereby 
 increasing the amount of local evaporation, and that a corresponding increase in precipitation will 
 follow over the same region, is hardly justified by the meteorological records. Precipitation over 
 the Dakotas is not the result of local influences. It has been shown that the controlling influence 
 in precipitation comes from a vast system of cyclonic circulation or atmospheric eddies passing 
 across the country near the forty-ninth parallel, absorbing moisture from the waters of the Pacific, 
 the snowbeds of the Rockies and Sierra Nevadas, and the warm waters of the Gulf. 
 
 18. Prairie fires should be prevented, as they increase evaporation by setting up convection 
 currents in the atmosphere and augmenting the drying effect of the usual winds. 
 
 19. Both Dakotas need a greater variety of wind currents. The abnormal excess of northerly 
 and southerly winds is productive of destructive extremes in temperature and evaporation. 
 
 20. As the population of the two States increase the deleterious effect from deficiency in pre- 
 cipitation and high evaporation must become more severe unless overcome by the employment of 
 irrigation. Mr. J. J. Gushing, of Ashton, S. Dak., testified before the Senate Committee on Irri- 
 gation in 1889 as follows: 
 
 In Dakota Territory the best calculation for the last two years places the loss at $25,000,000 a year from the fail- 
 ure of its water supply. 
 
 21 The occurrence of drought in the Dakotas bears such a close relation to the distribution 
 of atmospheric pressure over the north-central portion of the United States that it becomes an 
 inevitable result unless obviated through the intervention of artificial influences.

APPENDIX No. 2. 
 
 Chronological list of stations in North Dakota, South Dakota, Nebraska, Iowa, and Minnesota, with 
 reference to location and to character and extent of meteorological observations. 
 
 The names are arranged alphabetically without regard to geographical position. The latitude and longitude 
 have been taken from the latest standard maps. In the ease of broken records the extent of the missing portions 
 can be ascertained by reference to the tabulated data elsewhere in this report. The elevations above sea level have 
 been taken from the Dictionary of Altitudes, U. S. Geological Survey, and from the Weather Bureau reports.
