OFFICE SURVEY N. AND N. W. LAKES,
Detroit, October 20, 1860.
COL. J. J. º ical Eng?
8 A. O'OOO!!!"OMO/62C ng?neers,
Corps Topograph wº. D. C. :
SIR :—
I have the honor to submit herewith “A Report upon the
progress during the past year, of the Survey of the Northern and
Northwestern Lakes,” and have attached thereto “An estimate of
the amount required to be appropriated, for the continuance of the
Survey, during the fiscal year beginning July 1, 1861.” The last
annual report was dated Oct. 7, 1859, and was written at the close
of the field operations of that year, reporting the same to date. By
the 20th of November, the last party, under the charge of Lieut. O. M.
Poe, Top. Eng’rs, returned from the North end of Lake Huron, Lieut.
Poe having succeeded in effecting the connection between the survey
of Lake Huron, and the previous one of the Straits of Mackinac.
The energy and tenacity of purpose exhibited by Lieut. Poe in thus
remaining to so late a period on this exposed coast, and his success-
ful accomplishment of a greatly desired object, merit, as they have
received, my most sincere thanks.
Early in November, the work of computation and projection of
the data obtained in the field was commenced, and uninterruptedly
continued till the month of May, 1860. The amount of work exe-
cuted during this period by each party, as also the operations of
that branch of the Survey including the reduction for engraving,
publication and distribution of the published charts, will be first
briefly recapitulated. An account will then be given of the field
operations of the current season, and finally the estimate, and the
reasons explanatory of the same, will be submitted.
OFFICE WORK.

Projection of Off-shore Hydrography. The deep soundings off
the coast of Lake Huron from Cockburn's Island to Saginaw Bay,
and from Forrestville to Cape Ipperwash, were º by Assts.
J. A. Potter and O. N. Chaffee, on 5 sheets, containing 1,807 square
inches of hydrography. These gentlemen also drew 3 charts for field
4
use, and made 35 tracings of shore line maps, comprising 750 miles
º: COaSt.
e-lène Topography and Hydrography. Assts. W. H. Heardin
and W. T. ôj ected #. %, field-work on 4 .
on a scale of TH+ws, 2 of the North shore of Lake Huron, comprising
parts of Drummond's and Cockburn's Islands, and 2 of the South-
West coast of the same lake, from above Lexington to the head of the
St. Clair River. These 4 sheets included 1,801 square inches of
minute topography and hydrography; their projection involving the
computation of several hundred triangles, in computing which Mr.
Hearding expresses his indebtedness to Asst. E. B. Wright. The
sheets of the lower end of Lake Huron, included the towns of Lex-
ington and Port Huron, besides numerous villages, and extended
Over a comparatively well settled country, the topographical features
of which, such as towns, roads, fields, &c., are all minutely laid down
by Asst. Hearding, with his characteristic accuracy and finish.
Assts. G. W. Lamson and E. B. Wright projected the season's field
work in Lake Superior, comprising the harbor of Marquette and ad-
jacent coast, together with Grand Island and the Eastern and West-
ern approaches, on 5 sheets, two on a scale of gºw, and 3 on a scale
of TH+ n, containing in all 2,635 Square inches of minute topography
and hydrography. On the completion of his office duties, Asst.
Lamson resigned his position on the Survey, being compelled to this
step by the demands of private affairs. The length of Asst. Lam-
son’s services, he having been connected with the Survey for over 9
years, and their value, due to his energy, capacity, and experience,
authorize me to notice his separation from the work, and to express
my sense of the loss to the Survey produced by his withdrawal.
Assts. H. C. Penny and H. Gillman projected their field work,
including that portion of the coast of Lake Huron between Presqu'ile
and Hammond’s Bay, and from the head of the St. Clair river to
Cape Ipperwash, on 6 sheets, on a scale of TE-TV, comprising 2,300
square inches of minute topography and hydrography. The sheets
from the St. Clair river to cape Ipperwash show a well settled coun-
try, with several villages, including much detailed work, to exhibit
the topographical features of the ground, all of which are carefully
and accurately projected by Assts, Penny and Gillman.
Geodetic Computations. Lieut. O. M. Poe, Top. Eng’rs, reduced the
angles and computed the sides of the triangulation from Thunder
Bay to Presqu’ile, also the azimuths and length of the astronomical
bases from Presqu'ile to Hammond's Bay. By these computations,
the telegraphical longitude of Detroit is carried to the Straits of
Mackinac triangulation, through the west coast of Lake Huron, by
means of geodetic and astronomical observations. The result proved
that both the longitudes dependent on the Sand Point meridian, in
Saginaw Bay, and those of the Straits of Mackinac, dependent on
the meridian of Round Island, were subject to a correction, which
Lieut. Poe has applied, and in his report, hereto attached, marked
Appendix I, he gives a table of Geographical positions, from Detroit
5
through Lake Huron and the Straits of Mackinac to the Beaver Is-
lands in Lake Michigan, showing the latitudes and longitudes of the
most important points, corrected to date. Lieut. W. P. Smith, Top.
Eng’rs, computed the geodetic positions of the points, in the triangu-
lation of the South end of Lake Huron, and the necessary data for
their correct projection on the charts.
Astronomical Computations. The observations made for the lon-
gitudes of the Fort Gratiot station and of Forrestville, together with
those made for the latitude of Wahley’s Station, Lake Huron, were
severally computed by Assts. Jas. Carr and E. P. Austin. The ob-
servations for the latitudes of the stations at Presqu'ile and Sand
Bluffs, Lake Huron, were likewise computed by Lieut. O. M. Poe, Top.
Eng’rs. The results of these computations are embodied in the report
of Lieut. Poe, herewith attached, marked App. 1.
Reduction of Meteorological Observations. As soon as the with-
drawal of the parties from the field permitted, Lieuts. W. P. Smith
and R. F. Beckham, Top. Eng’rs, were assigned to the duty of
reducing the numerous meteorological observations made at the
several ia. Survey Stations. These gentlemen were unremittingly
occupied in this work during the winter, and the result of their
labors is contained in the report of Lt. Smith, hereto annexed, marked
App’x 2. In his report, Lieut. Smith gives numerous tables, showing
the daily means of the pressure, total and gaseous ; the mean daily
temperature, elasticity, and humidity of the atmosphere ; the daily
resultant of the force and direction of the wind ; the mean degree of
cloudiness for each day, together with the amount of rain and snow,
all for each station to include the month of December, 1859. These
reductions were all made in accordance with the formula and tables
prepared under the direction of the Smithsonian Institution, by Prof.
Guyot, with the exception of the winds. Much difficulty was encoun-
tered in reducing the observations made on the force and direction of
the wind. After consulting Kaemptz, Drew, and other accepted me-
teorological authorities, and conferring with several distinguished me-
teorologists, it was found no uniform system existed for the treatment
of observations on the wind; the general plan being confined to
giving the direction and intensities of the prevailing winds. Un-
doubtedly the simplest plan would have been, to have tabulated the
actual observations, made four times daily. Not wishing, however,
thus to burden the tables, the treatment was adopted as described
in Lt. Smith's report, consisting in the effort to obtain a daily force
and direction which would produce on the mass of the atmosphere
in 24 hours the same proportional effect as was produced by the
winds actually observed. This method may be open to criticism ; it
was adopted, as stated above, for want of a more satisfactory method.
In time, when more data is accumulated, it is proposed to prepare
diagrams, showing the proportionate prevalence of the different
Winds, during the several months and seasons on each of the lakes.
It is also designed, when sufficient data will justify it, to prepare
diagrams, illustrating all the meteorological phenomena observed,
6
and eventually to discuss the results thus obtained in connection
with the laws of atmospheric changes, of storms, of climate, and all
other kindred subjects connected with meteorology. For this pur-
pose, as the services of Lieut. Smith were required in the field, this
branch of the Survey has been assigned to Asst. J. M. Bigelow, who
will henceforth devote his whole attention, under my immediate
direction, to the reduction and discussion of these observations. The
tables attached to this report are but the commencement of what it
is hoped the future will furnish, and are now submitted to show the
progress of the work, and as an evidence of the character of its pros-
ecution. When these observations were commenced, having in
view the fluctuations of the water-level, in connection with which
the system was established, the hours of observation were fixed at 6
and 9 A.M., 3 and 6 P. M. Having ascertained from experience
that the fluctuations were so slight from day to day as to permit a
reduction in the number of daily observations, on the 1st of June
last the hours were changed to 7 A. M., 2 and 9 P. M., being the
same hours as those adopted by the Smithsonian Institution ; the
mean of which approximated the nearest to the mean of hourly
observations. In order to ascertain what correction was required
to reduce the mean of the four observations to the true daily mean,
I directed the observer at Thunder Bay Island, Lake Huron, to make
hourly observations on five days in each month ; these days being
separated by equal intervals; these hourly observations to commence
in January, and continue throughout the year, as the correction
would probably vary for each month. The table in Appendix 2,
contains the reduction of some of these hourly observations, and
affords satisfactory evidence that there is not likely to be any cor-
rection of material value to be applied. It will be seen from this
table, that the mean for the hours selected for the Lake Survey obser-
vations, viz.: 6 and 9 A.M. and 3 and 6 P.M., differ from the mean
of the hourly observations during the month of February, 1860, as
follows :
Bar. Dry bulb. Wet bulb.
Daily mean of hourly observations, 29.278 15°.3 14°.5
66 “ by L. Survey observ's, 29.278 15°.2 14°.4
Differences, 0.000 +0.1 +0.1
The above quantities are so small as to fairly fall within the limits
of the errors of observation. I have to express my Satisfaction at the
readiness with which J. J. Malden, Esq., the observer at Thunder
Bay Island, responded to my call for the additional observations.
So great was his anxiety to do all in his power to advance the cause,
that for several months he made hourly observations, day and night,
with all the meteorological instruments under his charge; the reduc-
tion and discussion of which, it is believed, will prove of great value
in determining the hourly fluctuations of the atmospheric phenom-
ena in the Lake region. Thunder Bay Island was selected, from its
being nearly the geographical centre of the Lake Survey Stations,
7
and also because reliance could be placed on the zeal and accuracy
of the observer.
Reduction of Water-level Observations. This branch of the Survey
has been greatly retarded, from the difficulty of finding time, and
assistance to make the necessary computations and drawings. Each
of the assistants, on returning from the field, has full occupation with
the office-work immediately connected with his summer's work; and
it is only at intervals that one can be spared to attend to any extra
or miscellaneous duty. The assignment of an assistant also is only
temporary, involving changes and consequent loss of time, as each
has to become familiar with the subject, and the labors of his prede-
cessor. At the commencement of the winter, the duty of making
these reductions was assigned to Assts. D. F. Henry and A. C. Lam-
son. Early in the spring the exigencies of the service required the
transfer of Asst. Henry to other duties. The hiatus in the progress of
the work thus produced, continued till late in the summer, when I
was able to assign Asst. J. M. Bigelow permanently to this duty,
as well as to the meteorological department of the Survey as previ-
ously stated. These remarks are made in excuse for my inability
to present such a report upon the fluctuations of the level of the
lakes as might have been done with more constant and permanent
assistance in the rednctions and drawings. Asst. Henry's labors
during the winter resulted in drawing 3 sheets of daily oscillations;
5 sheets of the mean level of the lakes eliminating the influence of
winds; and 1 sheet of monthly levels for 10 years, from 1851 to
1860, including each of the lakes and the Detroit river. In addition
to these drawings, and the computations on which they were based,
Assts. Henry and Lamson prepared tables of the relative levels of
the zeros of each of the stations, of the maxima and minima of the
daily winds, and of the monthly means of the different stations on
each lake. Upon Asst. Bigelow taking charge, the work left unfin-
ished by Asst. Henry was continued to include the month of August,
1860, the curves being drawn by Asst. C. P. Rabaut, and the com-
putations made by computers J. and H. Clague.
In submitting the results of the above described labors, I deem it
proper to mention that these computations and drawings were not
completed when the period arrived for making this report, so that
it has been utterly out of my power, for want of the data and time,
to give these results the attention and the careful study which the
subject demands, and that I now submit them to show the progress
of the work, briefly relating the process by which they were derived,
and glancing at some of the principal facts exhibited by them.
The stations at which observations have been made are, in Lake
Ontario, Sacket's Harbor, Charlotte, and Fort Niagara; in Lake Erie,
Buffalo, Erie, Cleveland, and Monroe pier; in Lake Huron, Pt. aux
Barques, Ottawa Pt., Thunder Bay Island, and Presqu’ile; in Lake
Michigan, Grand Haven, Michigan City, and Milwaukee; in Lake
Superior, Sault St. Mary, Marquette, Ontonagon, and Superior City.
The Water gauge, placed at each of the stations, consists of a
8
double box, in which is a metallic float with a graduated rod. The
point from which the rod was read, or the gange Zero, was in every
instance referred by spirit-level to some permanent mark in the wi-
cinity. The readings were made each day, at 6 and 9 A.M., 3 and
6 P. M., the force and direction of the wind being observed at the
Same time.
In reducing these observations the first point was to endeavor to
obtain the relative level of the different zeros, and, if possible, to
refer all the observations to a common plane of reference. To effect
this object, the calm months of the year, June, J uly, and August,
Were selected for comparing the readings of the several gauges; and
the high water of the year 1838, the maximum level which the lakes
have reached since authentic records have been made, was selected
as the plane of reference, there being two stations, Cleveland and
Milwaukee, where this high-water had been observed and could be
directly referred to. The comparisons of the different zeros with
each other, and their reference to the high water of 1838, are con-
tained in Appendix 2, Table A.
On inspecting this table it will be seen that during the months of
June, July, and August, the readings of the Cleveland and Monroe
gauges, when grouped in series of 10 days to eliminate the winds,
show a comparative quiescence in the level of Lake Erie, and give
a very uniform difference, the mean of which, 1.29 feet, is assumed
as the quantity which the zero of Cleveland is above that of Monroe.
The zero of Cleveland being, by the observations of Col. C. H. Whit-
tlesey, 2.92 feet above the high water mark of 1838 at that place,
the zero of Monroe is assumed to be above that plane the difference,
or 1.63 feet. This assumption is, of course, based on the theory that
in calm weather the surface of the lake is of one level.
In like manner the gauges of Buffalo and Erie are compared with
Cleveland, and through it, referred to the high water of 1838.
In Lake Michigan, the observations of J. A. Lapham, Esq., at
Milwaukee, enable the zero of the gauge at that place to be referred
directly to the high water of 1838, and it is found to be exactly 1
foot above. Through the Milwaukee zero, the gauges at Grand
Haven and Michigan City are referred to the common place of re-
ference. To determine the relations of the zeros in Lakes Huron
and Superior to the high waters of 1838, in the absence of direct
comparisons with that place, it has been necessary to assume that
the high water of 1838 bore the same relation to the stage of 1859,
in those lakes, as it was known to have borne in Lakes Erie and
Michigan. This hypothesis is known not to be strictly accurate, but
the errors arising from its assumption will be eliminated by con-
tinuing the comparisons from year to year, and taking the resulting
mean. Comparing the zeros of Cleveland and Milwaukee, through
Thunder Bay Island zero, we obtain the quantity by which the zero
of Milwaukee should be above the high water of 1838 as 1.19 feet;
varying only 0.19 foot from the quantity given above as, direct
measurement; an accordance resulting doubtless more from the fav-
9
orable circumstances under which the comparison was made, than
from any accuracy of the theory on which it was based. It serves,
however, to give confidence to the only method that can be adopted
for reducing all these observations to one plane, and thus harmoniz-
ing them.
%. effort was made to obtain the relative level of Lakes Erie and
Michigan, through the surveys of the Rail Roads connecting them ;
but owing to the want of care in preserving field notes and plats,
no accurate and connected levels could be obtained. It is possible,
therefore, that the plan adopted does not give the absolute relation
of the zeros in one lake with those of another; it does not, however,
affect the relations of the zeros in the same lake; the fluctuations are
still the same; they are only referred to an imaginary plane of refer-
ence, which, for the purposes of reduction in each lake, is as good as
any other assumed plane, and may probably be used as a positive
comparison with the other lakes. After referring all the gauges to
the plane of the high water of 1838, all the observations were re-
duced to this plane. To eliminate the effect of the winds, the means
of the 4 daily observations were grouped in series of 10 days, and
the means of these 10 day means taken as the mean for the month;
the mean of the monthly means at each station was taken as the mean
for that month in the lake. -
Table B, Appendix 3, contains all these quantities, and, in addition,
the maxima, minima, and range, at each station, both from the daily
records and the 10 day means, thus showing the fluctuations, when
Subjected to the winds, and when, the winds being eliminated, the
range is due to the supply and discharge.
Table C, Appendix 3, is a condensation of Table B, and contains
the mean level of each lake for each month, with the intermediate
rise and fall, from September, 1859, to August, 1860. To illustrate
more fully the fluctuations due to the supply and discharge, without
reference to the winds, a sheet of profiles projected from the 10 day
means at each station, from September, 1859, to August, 1860, has
been prepared, and is herewith attached, marked sheet No. 1.
A careful examination of these tables and curves, will give an ac-
curate idea of the fluctuations in each lake, and also exhibit the ex-
tremes to which they are raised or depressed when under the
influence of winds and storms. Thus Table B shews, that during
the month of September, 1859, the mean level of Lake Superior, re-
ferred to the high water of 1838, was as follows: at Superior, 1.11
feet below; at Ontonagon, 1.19 feet below; at Marquette, 1.13 feet
below; and Sault St. Mary, 1.22 feet below; giving a mean for the
Whole lake of 1.16 feet below, which is the quantity found in Table
C. Also, in Table B we find during the month of November, 1859,
that the ranges due to winds in Lake Erie amounted to 5.59 feet at
Monroe; 1.65 feet at Cleveland; 2.75 feet at Erie; and 6.20 feet at
Buffalo. Whereas, the ranges at these places, when the winds are elim-
inated, were, Monroe, 0.42 feet; Cleveland, 0.21; Erie, 0.43; and
Buffalo, 0.87; indicating not only the greater effect of storms at the
2
10
extremities of the lake, but also, that the fluctuations due to the
Supply and discharge are slightly greater at the foot than the head
of the lake.
By examining Table C we ascertain the annual fluctuations in
each lake, with the rise and fall, as follows:

H. W. of 1859. L. W. of 1860. Fall | H. W. of 1860. Rise
Month. feet. Month. feet. in feet. | Month. feet. in feet.
Lake Superior,. ----|| Aug. 1.08 Feb'y 2.79 1-71 || Aug., 2.00 0.79
Lake Michigan,..... Aug., 1-09 || Jan'y, 2.18 1-09 || July, 1.59 0.59
Lake Huron,.......|| July, 0.70 || March, 1.93 1-23 July, 1.54 0.39
Lake Erie, --------- July, 0.62 Feb'y, 2.21 1.59 || May, 0.95 1.26
Lake Ontario, -----. July, 0.58 | Feb’y, 2.63 2.05 || July, 1.96 0.67
The above figures represent quantities below the H. W. of 1838.
From this it appears the high water of 1860 did not reach to the
high water of 1859, by the following quantities:
uperior, 0.92 feet; Michigan, 0.5 feet; Huron, 0.84 feet; Erie,
0.33 feet; Ontario, 1.3 feet; that during the high water of 1859,
Ontario was the highest of all the lakes, and Superior and Michigan
the lowest, that during the low water of 1860, Lake Huron was the
highest, Superior and Ontario being the lowest, and in the high
water of 1860, Lake Erie was the highest, Superior and Ontario be-
ing again the lowest ; that during the period of observation, the
greatest fall, 2.05 feet, was in Lake Ontario from July, 1859, to Feb-
ruary, 1860; and the greatest rise in Lake Erie, being 1.26 feet, from
February to May, 1860.
In order to shew the effects of winds and storms on the lakes, a
sheet of profiles has been prepared and is herewith attached, marked
No. 2, on which are projected the curves of the daily records, reduced
to the common plane of reference at all the stations during the
month of October, 1859, that being the most tempestuous month ob-
served. The wind waves are here rendered very manifest. The
greatest storm of the month was on the 18th, to illustrate the effect
of which more fully, Table D, Appendix 3, has been prepared, in
which are tabulated the daily records of the force and direction
of the wind at each station on this day. By inspecting the profiles,
it will be seen all the lakes were simultaneously affected by this
storm—its greatest effect being in Lake Erie, depressing the Waters
at Monroe and Cleveland, and elevating them at Erie and Buffalo.
On examining Table D, it will be seen the wind at Monroe was
from the W.S.W., or directly offshore, depressing the waters to their
minimum—while at Erie it was from the N.W., or directly on shore,
producing the maximum rise, as is shown in the profile. At Buffalo
the wind was from the west, a direction which was along the Canada
shore, and consequently producing but a slight elevation of the
11
water. In like manner in Lake Ontario we find this westerly storm
elevating the water at Sacket's Harbor and Charlotte, and depressing
it at Niagara. The effect is very sensible in the depression of the
Detroit River. In Lake Huron, the stations being all on the west
coast, the effect of the storm is to depress them all. In Lake Michi-
gan we find Grand Haven and Michigan City raised, while at Mil-
waukee the water is lowered. Finally, in Lake Superior, Sault St
Mary is raised and Superior lowered, while the effect is compara-
tively slight at Ontonagon and Marquette.
The data for the tables and sketches, thus far referred to, were all
obtained from the observations made on the Survey, and embody the
results of the first year's observations since the system was establish-
ed. Having courteously been furnished, by several other observers,
with data extending over a considerable period of time in some of
the lakes, I have deemed it of interest to compile from those obser-
vations, that could be connected with the observations of the Survey,
a series of profiles of each of the lakes and the Detroit River, ex-
tending from 1851 to 1860, or ten years. These profiles, reduced in
each lake to the high water of 1838, are projected in the accom-
panying sheet, No. 3. For the data of these profiles I have to
express my indebtedness, in Lake Ontario, to Prof. Dewey of
Rochester; in Lake Erie, to Messrs. C. H. Whittlesey and B. Stanard,
of Cleveland; in the Detroit River, to Jacob Houghton, Esq., Engi-
neer Det. Water Works; in Lake Michigan, to J. A. Lapham, Esq.,
of Milwaukee, and Brev. Lieut. Col. J. D. Graham, Top. Eng’rs, at
Chicago; and for copies of numerous observations made at Buffalo
and other points, by agents of the Bureau of Top. Engineers, to
Capt. J. C. Woodruff, Top. Eng’rs, Assistant to the Bureau.
An inspection of these profiles shews a remarkable parallelism in
the curves, proving that within small limits of time and quantity,
the lakes may be considered as rising and falling together. The
greatest fluctuation in all the lakes during the whole ten years
is in Lake Ontario, where, between the low water of 1857 and the
high water of 1858, there was a range of 4.5 feet. The observations
of Prof. Dewey, extending as far back as 1846, shews this to be the
maximum range during the whole period. Col. Whittlesey states
the extreme range of Lake Erie, as observed, to be 5.25 feet, and
Mr. Lapham's observations at Milwaukee, give for the extreme range
of Lake Michigan 5.5 feet. These facts are of the highest impor-
tance in the projection of works of harbor and river improvement,
as the estimated cost of dredging out channels, constructing sub-
marine foundations for light-houses, piers, &c., should all be based
on the lakes' being subjected to the ranges given above; for it is ob-
vious that to obtain a certain depth in a channel by dredging, the
amount of work to be executed, and its consequent cost, will vary
materially, according as the work is done in a high or low stage of
Water,
There has not yet been time, since the observations of the Survey
were commenced, for any general results to be deduced beyond what
12
are perhaps now well known. In fact, these observations and their
examination being as yet confined to the mere record of the daily
fluctuations, the developments produced by them are such as might
be expected from the drainage of a large section of country through
extensive basins connected by narrow straits, that is to say, it is seen,
First—That the lakes are sensibly and rapidly affected by winds
and storms, depressing the water on the side from whence the wind
blows, and raising it on the opposite side. -
Secondly—That independent of the wind fluctuations, the lakes
are subjected to changes of level, due to the relative proportions of
their supply and discharges; the supply arising from rains and drain-
age of the water-sheds, the discharges arising from evaporation and
the flow through their outlets.
Thirdly—That as a general rule these last fluctuations occur an-
nually, there being a high and low stage each year, the former in
summer, the latter in winter ; and that within small limits of time
these annual changes are very nearly simultaneous.
Fourthly—That these annual fluctuations, both the high and low
stages, vary in degree from year to year, they being the effects of
variable causes, and that the extreme range, as yet reported between
the highest and lowest waters, has amounted to 5.5 feet,_in other
words, the above phenomena are those of a great river flowing
through extensive reservoirs, which receive and absorb the freshets,
and thus modify, both in degree and time of occurrence, the Ordi-
nary fluctuations.
In concluding this branch of this report, I have to express my ex-
treme regret, that owing to want of time and means, no examination
and reduction of the records of the self-registering gauges has been
practicable; and that in consequence their discussion, with a view of
ascertaining the existence of reported phenomena, must necessarily
be postponed to another year. I have stated, in a previous part of
this report, the difficulties that have been encountered in effecting
the reduction of the data now submitted, and that I had been com-
pelled to assign an assistant permanently to this duty. By his aid,
together with such assistance as from time to time can be given by
others, I trust to be able to have reduced and discussed the interest-
ing records of the self-registering gauges; at the same time it is not
impossible, if additional means should not be furnished, that the in-
creased expenditures of the extra force required for this work may
prevent its being continued, and reference is therefore made to the
subject, that it may serve as an additional argument in favor of the
appropriation of the whole amount of the estimate which is pre-
sented in connection with this report.
Reduction for Engraving, Publication, and Distribution of Charts.
The charts reduced from the detailed sheets, for engraving and
publication, in the office of the Survey, since October 1, 1859, have
been as follows:

Four charts, tracings of each lake in the above chart, were made
by Asst. Rabaut. Asst. J. Barney, in addition to the two charts re-
ported above, has nearly completed the chart of the south end of
Lake Huron, scale Hºrºw.
The charts engraved and published since the date of the last re-
port are two in number, viz.:
Ontonagon Harbor, Lake Superior, scale stºry, published in 1860.
Saginaw Bay and part of Lake Huron, scale Tºwn, published in
1860.
Making in all nineteen published charts now distributed by the
Survey. i. charts that are now being reduced, or the data for their
reduction in the office, are as follows: -
South end of Lake Huron.
Grand Island and approaches, Lake Superior.
N. E. coast of Lake Michigan, including the Fox and Manitou
Islands, Grand and Little Traverse Bays,
Harbors of refuge at Northport, Little Traverse and South Mani-
tou, Lake Michigan.
To recapitulate, nineteen charts have been published to date, four
are now in the hands of the engraver, and six are either being re-
duced, or the data for their reduction in the office.
The demand for the published charts continues undiminished.
Although charts are issued both at the office in Detroit and at the
agency in Buffalo, and are not duplicated to vessels recorded in the
office registers as having once received them, yet it is with extreme
difficulty they can be printed fast enough to supply the demand.
The annexed table, Appendix 4, gives the monthly issue at both
places of distribution for each month during the past year, and the
table below shows the gross amount issued to Oct. 1, 1860, so far
as the same can be gathered from the records of the survey,

FIELD WORK IN 186O.
The foregoing part of this report refers to the work of the Survey
during the period the assistants are employed in the office; the ope-
rations of the different parties in the field, with the result of their
labors, will now be given.
In the last Annual Report it was stated, that in accordance with the
implied wishes of Congress, as inferred from the phraseology of the
law making appropriations for the Survey, the whole force of the Sur-
vey would the next season be placed on Lake Superior; and such was
fully the design up to the period when it was necessary to make ar-
rangements for taking the field. These arrangements require several
months, being the organization and equipment of parties, the assign-
ment of the work to different parties, and what consumes the most
time, the preparation of field-plots and sketches from the most reliable
authority to facilitate the laying out and execution of the work to
the best advantage. It is, therefore, quite necessary that the scene of
operations should be selected and these arrangments commenced as
early as March, each year. When this period arrived, it was found
the State of Michigan had begun extensive repairs and alterations to
the St. Mary’s River canal, the time of completing which was a
matter of great uncertainty. The contractors, to whom the State had
entrusted the work, expressed their confident ability to complete
the repairs by the opening of navigation. On the other hand, per-
sons experienced in such matters, in view of the condition of the
work at the period referred to, early in March, were equally as con-
fident the canal would not be open by the month of May, and some
placed the date of opening as late as July. Having endeavored to
obtain reliable information, resulting in the most contradictory state-
ments, only proving that the opening of the canal was a matter of
great uncertainty, I deemed it my duty to report all the facts of the
case to the Bureau of Topographical Engineers, and to recommend
that another field should be selected, as any delay in the opening of
the canal would proportionately delay the Survey, by preventing the
vessels and boats from entering the lake, and taking advantage of
the early part of the season. I accordingly recommended the ex-
tension of the previous survey of the Beaver Islands in the north
end of Lake Michigan, to include the Fox and Manitou Islands,
Grand and Little Traverse Bays; a portion of the lake region of the
greatest importance, as it is the highway connecting Buffalo and
Chicago, and as much frequented by vessels as any other part of the
lakes.
The Bureau of Topographical Engineers approving of the recom-
mendation, the organization and assignment of parties was made
with a view to executing the above survey, and completing that of
Lake Huron, which was not quite finished at the close of last season.
The parties placed in the field were in number and position as
follows: three shore-line topography and hydrography in Lake
15
Michigan; two triangulation parties in Lake Michigan, and one in
Lake Huron; two astronomical and one magnetic party operating
in both lakes, Michigan and Huron; and one offshore hydrographi-
cal party in each lake. e
In reporting the work of these parties, frequent reference will be
made to Appendix No. 6, containing the abstract of the work of
each, and to the sketch accompanying this report, marked No. 4, on
which is projected the field occupied.
Shore-line Topography and Hydrography—Early in May Asst.
W. H. Hearding, aided by Messrs. W. T. Casgrain and Jos. String-
ham, constituting a topographical party, was placed on the east
coast of Lake Michigan, near Middle village. Asst. Hearding was
directed to commence his survey at the point where the survey of
1855 terminated, and extend his work, carrying his soundings to
the limits of four fathoms in depth and half a mile in distance, till
he should connect with one of the other parties. This junction was
effected by the 1st inst., Asst. Hearding having in the mean time, as
will be seen by his report, traced 104 miles of shore-line, including
67 square miles of minute hydrography, and 30 Square miles of de-
tailed topography. This work includes Little Traverse Bay, and the
excellent harbor of refuge in it, the data for a chart of which is thus
obtained. Asst. Hearding's work also includes the whole of the east
coast of Grand Traverse Bay, he connecting with Asst. D. F. Henry,
at Deepwater Pt., in the Eastern arm of that bay.
Another topographical party under the charge of Asst. H. C.
Penny, with Messrs. H. Gillman and G. E. Swinscoe, for assistants,
was placed at Point aux Becs-sgies, on the east coast of Lake Mich-
igan, with orders to work in a northerly direction, under similar
instructions to those given Asst. Hearding, in regard to the limits
of the hydrography. Asst. Penny accomplished the task assigned
him by the 3d inst., connecting with Asst. D. F. Henry, near Tra-
verse City; having surveyed, according to his report, 108 miles of
shore line, including 65 square miles of minute hydrography, and
50 square miles of topography. Asst. Penny’s work includes the
whole of the west coast of Grand Traverse Bay, and the shore of
Lake Michigan, from the foot of this bay to Point aux Becs-sgies,
containing the harbor of refuge at Northport, a place of growing
importance, and several other settlements on the coast, already fre-
quented by steamers, and the approaches to which, when made
known, will prove of great value.
The third topographical party placed in the field was assigned to
Asst. D. F. Henry, with Messrs. E. B. Wright and A. M. Adams,
for assistants. Asst. Henry was directed to commence his work at
the South Manitou Island, to survey both the Manitous and Foxes,
on completing which, he was to commence at Deepwater Point,
in the Eastern arm of Grand Traverse Bay, and extend his work
around Mission Point till he effected a junction in the western arm,
with Asst. Penny. The duty assigned Asst. Henry, was successfully
accomplished by the 3d inst., he then connecting with Asst. Penny
16
at Traverse City. During the season, Asst. Henry reports having
Surveyed 91 miles of shoreline, including 513 square miles of minute
hydrography, and 50 square miles of topography. The surveys of
Asst. Henry furnish the data for a chart of the harbor of South
Manitou, a place of refuge of constant resort by vessels during storm
Weather; they also make known the approaches to the Fox Islands,
and their availability in affording anchorage and shelter in storms;
knowledge of the greatest value to navigators, as at present there is
but little known about them. -
It will be seen from the foregoing, that from the middle of May to
the 3d inst., a period of 44 months, the three topographical parties
accomplished the survey of 303 miles of shore, covering 183 square
miles of hydrography, and 130 square miles of topography, an
amount of work never exceeded in the annals of the survey, due in a
great measure to the favorable character of the weather in the early
part of the season, but principally to the energy and zeal of the
chiefs and assistants of parties, who, knowing my desire to accom-
plish this work during the season, left no exertions unspared to at-
tain the desired result. It is due to these gentlemen that I should
express my satisfaction, and return them my thanks, for their efforts
to respond to my wishes.
Triangulation—Primary and Secondary. 2d Lieut. J. L. Kirby
Smith, Top. Eng’rs, to whom was assigned the duty of carrying on
the primary triangulation, was occupied during the month of May
in completing the triangulation of the lower end of Lake Huron.
Towards the close of May, Lieut. Smith, with Asst. A. N. Lee, and a
party on the schooner Coquette, was sent to the North end of Lake
Michigan. Lieut. Smith was furnished with an outline chart of the
field, having projected on it a scheme of triangles, by which the
triangulation resting on the measured base in the Straits of Mack-
inac could be extended so as to cover the field to be occupied this
season. Lieut. Smith was instructed to make the necessary recon-
noissances for the selection of proper sites, to erect the stations, and
occupy as many of them as practicable during the season. . Inspect-
ing the work late in August, and finding Lieut. Smith had been so
fully occupied with reconnoissances and building stations, he would
not be able to occupy all, I assigned another party, under charge of
Asst. Jas. Carr, to ensure the observation of all the required angles.
From the reports of Lieut. Smith and Asst. Carr, it will be seen
that 20 stations have been occupied with over 1,500 pointings of the
theodolite, and the triangulation completed from the base “Hat
Island–Pt. aux Chenes” (see sketch No. 4,) extending to Pt. aux Becs-
sgies and including Grand Traverse Bay. The connection with the
base “Gull—High Island,” had not been effected; but it is hoped it
may be before the season closes; if not, it will be accomplished early
next season, as it will be requisite before extending the triangulation
from the Fox and Manitou Islands, across to Green Bay, the prac-
ticability of which is rendered highly probable from observations
made this season.
17
A secondary triangulation connected with the primary will be
extended over the lower part of Grand Traverse Bay, by Lieut. Smith.
This triangulation will connect with another of the East arm of the bay
by Asst. Hearding, and resting on a base of 8,000 feet, measured by
Asst. Hearding, at the head of the East arm, with the wooden rod
apparatus. At the junction of the two arms, Asst. Hearding's
triangulation was taken up by Asst. Henry, and extended up the
West arm of the bay to Traverse City.
A secondary triangulation around Cove Island, Lake Huron, to
obtain the position of the islands at the entrance of the Georgian
Bay, was executed in August, by Asst. Jas. Carr. These, several
systems of triangulation cover in all about 1,800 square miles.
‘shore Hydrography. The assistants assigned to this duty were
2d Lieut. W. Proctor Smith, on the steamer Search, in Lake Huron,
and Asst. J. A. Potter, with the aid of Messrs. O. N. Chaffee, A.
Lamson and H. Neill, on the steamer Surveyor, in Lake Michigan.
Asst. Potter was instructed to commence on the East coast of Lake
Michigan, near Middle Village, and extend the hydrography of the
shore parties, to a point 9 miles from the coast. The early part of
the season proving very favorable, Asst. Potter has been enabled to
carry the deep soundings 9 miles out, along the coast from Middle
Village to Pt. aux Becs-sgies, to extend them this distance around the
Manitou Islands, and finally to sound out minutely both Little and
Grand Traverse Bays. This extensive hydrography amounted, on the
30th ult, the date of Asst. Potter's report, to 2,260 miles of lines
Sounded, covering 1,200 square miles of water; and this amount is
exclusive of the work executed in Grand Traverse Bay, which has
been accomplished since the 30th ult. In addition to this very cred-
itable amount of work, Asst. Potter was employed for over 6 weeks
assisting the triangulation party, building stations and cutting out .
lines of sight, and the steamer under his charge has run some 3,000
miles on general duty, moving parties, procuring supplies, &c., af.
fording very satisfactory evidence of the efficiency of the vessel.
2d Lieut. W. P. Smith, Top. Eng’rs, with Asst. J. S. Meade, on the
steamer Search, has, during the past season, completed in the most
satisfactory manner the off-shore hydrography of Lake Huron, by
running a series of lines of soundings at an average distance
apart of 10 miles, in an east and west direction, and extending the
whole length of the lake, from the St. Clair to the St. Mary's river.
These lines, by their projection, will furnish an accurate representa-
tion of the form of the bottom of this lake, and will, it is believed,
develop some highly interesting facts. In connection with these
soundings, Lt. Smith made observations on the character of the bot-
tom, and on the temperature of the water at different depths, at va-
rious and numerous points. In the execution of this duty, minute
examinations, were made, in search of reported shoals, in the vicinity
of Thunder Bay Island, without, however, finding the shoal ground
where reported. ... Having, however, on inspecting the Soundings,
perceived indications leading to the belief that the shoal ground
3
18
might possibly lay further South than was reported, Lt. Smith was
sent early in this month to continue his explorations in search of the
same, with what result is not yet known. Up to the 30th of Septem-
ber Lieut. Smith reports having run in Lake Huron 2,383 miles of
lines of soundings. In addition to the above hydrographical duty,
Lieut. Smith was employed on the steamer Search in transporting
the chronometers, for determining the differences of latitude between
Goderich and Cove Island, and Cove Island and Mackinac. During
the month of September, the hydrographical party on the steamer
Search was under my immediate direction, and consisted of 2d Lieuts.
W. P. Smith and R. F. Beckham, Top. Eng’rs, and Asst. J. S. Meade,
the operations being confined to the hydrography around the Fox
Islands. The boisterous character of the month, together with the
diversion of the steamer to attend to the triangulation and other
miscellaneous duties, so retarded the work around these islands that
it was impossible to complete it this season. Lieut. Smith's report
states, that in addition to the hydrographical duty reported as exe-
cuted on the steamer Search, this vessel has run on other duties this
Season over 10,500 miles, proving, in connection with the work re-
ported of the steamer Surveyor, the value of this class of vessels
in conducting the operations of the Survey, and the true economy of
their employment, in view of the time gained and the amount of
work accomplished by them.
Astronomical Observations. Two astronomical parties were placed
in the field this year : one under the charge of 1st Lieut. O. M. Poe,
Top. Eng’rs, assisted by 2d Lieut. R. F. Beckham, Top. Eng’rs; another
under the charge of Asst. James Carr, aided by Asst. E. P. Austin.
Both parties were placed in Lake Huron, where the latitudes and
longitudes of several points on the Eastern coast were required, for the
incorporation into the chart of this lake of the most reliable surveys
of such portions as were not included in our surveys. At the same
time, desiring to obtain the longitude of some point of the Mackinac
triangulation with all the accuracy attainable, it was determined to
transfer the longitude of Detroit to Goderich on the East coast, by tele-
graph, and from thence, by transfer of chronometers, through Cove
Island at the entrance-of the Georgian Bay, to the Straits of Mack-
inac. Upon application, permission was most courteously granted to
use the lines between Detroit and Goderich, by H. P. Dwight, Esq.,
the Supt. of the Montreal Telegraph Co., no charge being made for
their use during the hours of observations; and my thanks are due to
Mr. Dwight for his liberality in affording all the facilities required
for the work. Early in March, Lieuts. Poe and Beckham were
sent to Goderich, and Assts. Carr and Austin assigned to the Obser-
vatory of the Survey at this place. Each station was furnished with
a sidereal clock and chronograph, and all necessary telegraphic ap-
paratus for the exchange of observations and free communication.
The method of operations was similar to that described in the last
annual report as employed between Detroit and Hudson, and is
therefore not here repeated. The report of Lieut. Poe, who had the
19
immediate direction of operations, will be found in Appendix 1. and
is referred to for the details and the results. He reports, that owing
to the length of the line between Detroit and Goderich, and the weak-
ness of the Goderich battery, it was at times difficult to work be-
tween the two observatories; the results are nevertheless extremely
satisfactory, affording evidence of the high value to be attached to
this method of determining differences of longitude. Lieut. Poe ac-
knowledges his indebtedness to the citizens of Goderich for facilities
afforded, and he speaks particularly of the obligations he was placed
under by Mr. Cameron, the Mayor of the place, who secured him
suitable ground for the observatory, and extended towards him nu-
merous official courtesies.
An examination of Lieut. Poe's report will show that signals were
exchanged on 4 nights, during which time there were 99 star signals,
exchanged, 11 comparisons of local time through the clock beats, and
103 arbitrary signals, and that the greatest difference between the re-
sults of either of these methods amounts 0°.043 of time. In addition
to determining the longitude, Lieut. Poe observed at Goderich with
the Zenith telescope for the latitude of his station.
Upon completing the observations for the longitude of Goderich,
Assts. Carr and Austin were tranferred from Detroit to Cove Island,
at the entrance to the Georgian Bay, in Lake Huron ; the latitude
and longitude of which was accurately determined, the former by
observations with the zenith telescope, the latter by comparisons of
the local time through the exchange of chronometers with Lieut. Poe,
at Goderich. In this operation, each observer having his clock accu-
rately rated by frequent observations, the chronometers of the Survey,
which by the liberality of the Department now amount to 12, after
being compared with the clock of one station, are carefully trans-
ported in one of the steamers of the Survey to the other station,
where a comparison being immediately made with the clock, the
chronometers are at Once sent back to the first station, and continue
thus to be carried from one station to the other, till a sufficient num-
ber of comparisons have been obtained. According to Lieut. Poe's
report, the chronometers were sent 6 times from Goderich to Cove
Island and returned, making 12 comparisons in which each chro-
nometer gave a difference of longitude. The mean of these results is
believed to be quite near the true result, and the observations, not-
withstanding some of the trips were made in rough weather, accord
remarkably well with each other.
Having established the longitude of the meridian at Cove Island,
Lieut. Poe and party was transferred to Mackinac, and the longitude
of the Fort Holmes station of the triangulation of the straits of
Mackinac determined in a similar manner. A comparison was in
this way obtained between the longitude brought from Detroit by
astronomical and geodetic operations on the West shore of Lake
Huron, with the results obtained this season by transferring the lon-
gitude of Detroit, as has been described, through points on the East
shore. The comparison, I am gratified to report, proves highly credit.
20
able to the accuracy of the astronomical observations of the Survey,
since the difference in the longitude of the Fort Holmes Station
by the two systems amounts to 0°.55 of time only. The mean lon-
gitude thus obtained will be transferred through the triangulation of
the Straits of Mackinac to the points constituting the bases of this
season's triangulation, terminating at Pt. aux Becs-Sgies, Lake Mich-
igan. It was my purpose to have connected this last station chron-
ometrically with Grand Haven, on the east coast of Lake Michigan,
and to have connected the latter place by telegraph with Detroit,
thus returning with our longitudes to the primary meridian after tra:
versing Lakes Huron and Michigan. The lateness of the season and
the exigencies of the Survey requiring the temporary transfer of Asst.
Carr to the triangulation, required the postponement of part of this
plan. Asst. Carr having completed his triangulation duties is, how-
ever, at present, at Grand Haven, which will at once be connected
through the telegraph with Detroit, and early next season, it is
hoped, the chronometric connection between Grand Haven and this
year's triangulation will be effected.
In addition to the above reported astronomical observations, Asst.
Jas. Carr determined from observation with the zenith telescope the
latitude of Cape Ipperwash, Lake Huron; and Lieut. Poe made a
telegraphic connection for difference of longitude with Prof. Jas. C.
Watson, Director of the Observatory of the University of Michigan,
at Ann Arbor. The Observatory at Ann Arbor not being supplied
with the requisite apparatus for the exchange of star signals, arbitrary
signals were transmitted on two nights, giving a result, as will be
seen by examining Lieut. Poe's report, (Appendix 1,) differing 0°.3
: time from the longitude of the Observatory as deduced from occul-
ations. -
Magnetic Observations. Lieut. Wm. Proctor Smith, Top. Eng’rs,
to whom was assigned this duty, has obtained the magnetic elements
during the season at such points as the execution of the other duties
assigned to him permitted. The results of these observations are
embodied in the table in Appendix 5, and show the occupation by
Lieut. Smith of 9 stations: 5 in Lake Huron, 3 in Lake Michigan, and
1 in the Straits of Mackinac.
Water-level and Meteorological Observations. The daily observa;
tions on the rise and fall of the lakes, together with meteorological
observations, have continued to be made during the season at all the
stations heretofore enumerated as occupied by the observers of the
Survey. It was intended to increase the number of stations, partic-
ularly in the Northern end of Lake Michigan, but the appropriation
asked for not being granted, prevented any increase of expenditure
in this branch of the Survey. The only additional station there-
fore, occupied this season, is one at Lake George, St. Mary's River,
where observations had been previously made under the direction of
Capt. A. W. Whipple, Top. Eng’rs, in charge of the improvement of
the navigation; and where it was particularly important to continue
the observations, owing to their direct bearing on the questions rela-
21
ting to this improvement. I am indebted to Capt. Whipple for
copies of the observations made under his direction, from July, 1859,
to August, 1860, which, though reaching me too late to be embodied
in the report now made on the fluctuations for this year, will never-
theless prove of great value in the future discussions and studies that
will be made on this subject. All the stations this year were fur-
nished with maxima and minima thermometers. Each station was
inspected, and the instruments examined, the barometers being com-
pared with one carefully compared with the standard at the Detroit
Observatory, both before and after the inspection tour. The instru-
ments were all found to be in good order, the variations from the
standard barometer being inappreciable, a result that is extremely
gratifying, when it is remembered what distances these instruments
had to be carried over, and how much handling they were necessarily
subjected to, before being placed in position. The self-registering
water gauge, placed last year at Ontonagon, was this year transferred
to Marquette, in consequence of the difficulty of finding a suitable
location for it at the former place, owing to the shifting character of
the river deposits. The gauge last season was placed in 12 feet wa-
ter, and this year the sand was banked up around it entirely out of
Water.
The observer at Thunder Bay Island has been furnished with a
deep-seathermometer, for observations on the mean temperature of the
lake, which he will now make throughout the year, unless prevented
by ice. Should the appropriation now called for be granted, and
the means furnished for employing additional assistance, it is pro-
posed to have a series of simultaneous observations made at each of
the outlets of the lakes, for the purpose of determining their relative
discharges. These should be made for several months, and should
consist in accurate observations on the rise and fall of the outlets,
and the velocity of the currents.
SUMIMARY OF YEAR’S WORK.
A recapitulation of the foregoing account of the operations in the
office and the field, exhibits the projection of 29 manuscript sheets
of hydrography, topography, and water levels; the reduction of 4
charts for engraving ; the drawing of 1 chart for the Lighthouse
Board; the publication of 2 charts; the reduction and tabulation of
140 monthly sheets of meteorological observations, together with
numerous other computations, astronomical and geodetic; the survey
of 303 miles of lake shore, covering 313 square miles of minute
topography and hydrography; the execution of two triangulations,
extending over 2,200 square miles; the sounding in deep water of
4,300 miles of lines; the determination of the latitudes of 3, and
the longitudes of 4, points; the observation of the magnetic ele-
ments at 9 points; and finally, the continuation of the meteorologi-
cal and water-level observations over the whole lake region.
Estimate of funds required for the continuation of the work.-The
22
regulations of the army require the officer in charge of the Survey
to submit, with the report he is called upon annually to make of the
progress of the work, “an estimate of the funds necessary to be ap-
propriated for its further prosecution.” In compliance with this
requisition of regulations, I beg leave to submit the estimate accom-
panying this report, which will be found in the Appendix No. 7.
It provides in general terms as follows:
For two hydrographical parties, - - - $24,418 60
For two triangulation parties, - - - 11,177 50
For two astronomical parties, - * - 6,818 00
For four topographical parties, se - 29,596 40
For miscellaneous expenditures, - - - 19,236 00
For contingencies, - - - ºn tº 9,124 65
For an additional steamer, - - * - 25,000 00
Amounting in all to - - - $125,371 15 .
Being the same in amount and in detail as the estimate submitted
with last year's report. It provides for a slight increase of the per-
sonel of the Survey, and for an increase of a steamer to the equip-
ment.
I have to refer to the reports from this office for the last and pre-
ceding years, in which an effort has been made to show the impor-
tance of an accurate Survey of the Lake region, and the undoubted
economy that would result from larger appropriations. The opera-
tions of the present season are strikingly illustrative of this fact.
With an appropriation of $75,000, and an equipment of 2 steamers
and 1 sail vessel, an amount of work has been accomplished, that with
the former appropriation of $50,000 and equipment of 1 steamer,
would have occupied 3 seasons to execute. In other words, the ad-
ditional steamer and vessel, together with $25,000 increased appro-
riation, has caused a saving of time amounting to 2 years and
of $75,000 in money; and I have no hesitation in affirming, as my
undoubted belief, based on my knowledge of the work, and experience
acquired on it, that the granting of the estimate now submitted, in-
cluding the additional steamer, would result in the annual saving of
$50,000 in the final cost of the work—that is to say, with an addi-
tional steamer and an annual appropriation of $100,000, I am fully
of the opinion that twice the amount of work can be accomplished
each season, than with the smaller appropriation and reduced equip- .
ment. The additional equipment of a steamer is perhaps more nec-
essary than the increased appropriation. The Survey of the Lakes,
in some respects, differs from other works of a similar character.
The shores of the upper lakes which are now being surveyed are, as
a general rule, uninhabited; special means of transportation have to
be provided, not only for placing parties in the field, but for moving
them from point to point when there. Being removed from all
sources of supply, everything required for the Survey during the
whole season, has to be carried by each party from the beginning,
23
involving greatly increased transportation from what would be re-
quired in a country where there were settlements, roads, and means
of conveyance to be procured, when wanted. In consequence of
these difficulties, more men and boats have to be employed than
otherwise would be necessary, resulting in having additional camp
equipage and subsistence stores, and thus the character of the coun-
try directly increases the expenditures of the Survey. Again, the
season for operations in the high latitudes of the Survey is limited
in duration; 4 months being all that past experience justifies reliance
being placed on, viz.: from June to September. It is true, the par-
ties are placed in the field at an earlier and withdrawn at a later
period than is designated above, but the amount of work, both before
and after, hardly justifies the expenditures made to secure it.
With these facts in view, viz.: the character of the country, and
the shortness of the season, it will be evident that economy must be
promoted by any means which will increase the power of locomotion
and reduce the time required to accomplish the work. This is pre-
cisely what steamers effect, and it is for this reason, an appropriation
for an additional steamer is so urgently pressed on the consideration
of the Bureau. It is also for the reason that I believe the completion
of the Survey will be greatly advanced in time, and the final cost
greatly diminished in amount, by larger appropriations, that I re-
commend an increase to the annual appropriation, and I sincerely
hope the present estimate will be granted in full, without reduction.
As to the great importance of the Survey, it has been so fully and
repeatedly set forth, and so generally conceded by all those cognizant
of its operations, or interested in its results, that it seems almost use-
less to allude to it. With a coast equal in length to that of the At-
lantic and Gulf of Mexico, with a commerce equal to the whole for-
eign commerce of the country, amounting to nearly half a million
of tons of shipping, with the whole navigation one of danger, and
throughout the greater part embarrassed by reefs, shoals, and other
obstructions, it would seem as if all classes of the community, the
navigator, the underwriter, the merchant, the traveler, whether for
business or pleasure, were all interested in the prosecution of the
Survey and directly benefitted by its results. The government itself,
through its Bureaus of Lighthouses, Fortifications, River and Harbor
improvements, &c., is directly interested and benefitted. In view,
therefore, of the vast importance of the work, and of the undoubted
fact that the more liberal the appropriations the earlier it will be
completed, I conclude this report with a repetition of my earnest
hope that the submitted estimate will be granted in full.
Very Respectfully,
Your Obedient Servant,
GEO. G. MEADE,
Capt. Top. Eng’rs.

APPENDIX No. 1.
ANNUAL REPORT, SURVEY N. & N. W. LAKES.
OFFICE. U. S. SURVEY OF THE N. & N. W. LAKES,
Detroit, October 1st, 1860.
To CAPT. GEO. G. MEADE,
Top. Engs. U. S. Army, Supt. Lake Survey.
SIR:—I have the honor of forwarding the following report of the
operations in the Astronomical Department of the Lake Survey,
since the date of the last annual report. I have arranged the several
operations in the following order:
Fºrst—Tables showing the results of the observations: 1st, for
difference of longitude between Detroit and Fort Gratiot, Mich., by
the method of chronometric expeditions; 2d, for difference of longi-
tude between Fort Gratiot and Forestville, Michigan, by the same
method; 3d, for the latitude of U. S. Lake Survey Station Sanilac,
Mich. The operations, from which tables No. 1 and 2 were deduced,
were conducted by Lieut. C. N. Turnbull, Top. Eng’rs, assisted by
Mr. Jas. Carr ; those of No. 3 by Mr. Carr, assisted by Mr. Austin,
of whom Mr. Carr speaks in terms of commendation.
Second–Tables containing the general results of the observations
for the latitude of the stations Bluffs and Presque Isle, and the re-
Sults of the geodetic operations for determining the longitude of
Presque Isle station, Bluffs station, and station Mast. These tables
are denominated severally, No. 4, No. 5 and No. 6.
Third–Tables from No. 7 to No. 15 inclusive, which embody the
results of the telegraphic connection between Detroit, Mich., and
Goderich, Canada West, for the determination of the longitude of
the latter place. Also, the general results of the observations for
the latitude of Goderich, and the connection of the observatory with
certain points in the town.
Fourth—Table No. 16, containing the general results of Assistant
Carr's observations for the latitude of Cape Ipperwash, Canada West.
Jºfth—Tables No. 17 and 18, which contain the results of the
chronometric expeditions for the determination of the difference of
longitude between Goderich and Cove Island, situated at the entrance
from Lake Huron into Georgian Bay; and the general results of
the observations for the latitude of Cove Island.
Sæth—Table No. 19, containing the results of the chronometric
expeditions between Cove Island and Mackinac, for the determina-
tion of the longitude of Fort Holmes.
Seventh—Table No. 20, which shows the clock rates used in the
determination of the difference of longitude between Goderich and
Cove Island, and between Cove Island and Mackinac.
Fighth—The final longitude of Fort Holmes station, on Island of
Mackinac.
25
Mºnth—The difference of longitude between Detroit, Mich., and
the observatory of the University of Michigan, at Ann Arbor, by
the method of arbitrary signals.
Tenth—A table of “geodetic positions,” corrected to date, and
containing every important point yet determined, from Detroit,
around through Lake Huron and the Straits of Mackinac, to the
western end of the Beaver Group, inclusive.
Agreeably with your orders of March 10th, 1860, I repaired to
Goderich, Canada West, on the 12th, and begun the work by putting
the instruments in position and making the necessary telegraphic
connections. The method of doing the latter was the same as de-
scribed in the “Annual Report of the Superintendent of the Lake
Survey for 1859.” The observatory at Goderich was interposed be-
tween the relay magnet and talking key of the telegraph office, the
ground wire being at the latter place, and the batteries of the Tele-
graph Company being used.
The instruments used were, at Goderich, Wurdemann transit, No.
15, having a focal length of 32 inches; sidereal clock, No. 256, by
Bond & Sons, Boston, which has a mercurial compensating pendu-
lum, and attached to it a break circuit apparatus, operated by means
of a pin projecting from the pendulum, which strikes the angle of
a V bent in the delicate spring through which the electric connection
is made. This spring is firmly clamped in a metallic socket at one
end, while the other freely dips into a cup of mercury. The tele-
graph wires connect with both the clamp and the mercury. When
the pendulum is at rest, the circuit is broken, the angular point of
the V resting on the projecting pin. When the pendulum is in
motion, the pin, at each beat, passes the angle of the V and raises
the spring high enough to lift the movable end out of the mercury,
and of course breaks the circuit. The record of clock beats and
observations was made on a chronograph, constructed by Bond &
Sons, which was operated by a local battery.
At Detroit were used the old transit of the Lake Survey, originally
made in England, but rebuilt by Wurdemann ; sidereal clock, No.
184, by Bond & Sons, and a chronograph by the same makers, the
arrangement of wires, switches, &c., being the same as at Goderich.
The observations at Goderich were made by mysélf, assisted by
Lieut. R. F. Beckham, Top. Eng’rs, and at Detroit by Mr. Carr,
assisted by Mr. Austin.
After instruments were in position, the mode of procedure was
as follows: Duplicate lists of stars had been made, and the stars on
them numbered 1, 2, 3, &c. Goderich being to the eastward of De-
troit, warned that station when in readiness for work, giving the
list number of the star which would be first observed, and also the
direction of the illumination. When the star was within a few
Seconds of the first wire, a rattle was made to indicate that the ob-
servation was about to begin ; and again, after the star had passed
all the wires, to indicate that the observation was finished at Gode-
rich. This operation was repeated at Detroit, when the star reached
4
26
the meridian of that place, each observation being recorded at both
stations. The levels were read, both before and after each observa-
tion, at each station, and the instruments reversed in the Y’s, thus
keeping the illuminated ends of the axes of the two transits always in
the same direction. The chronographs presented a complete record
of all the observations made at the two places, and the error of each
clock was determined for both meridians, the difference of longitude
being equal to the difference of these errors. The arrangement of
Switches, &c., was such that either clock could be thrown into the
main circuit, registering its beats at both stations; or both could be
thrown into the main line at the same time, in which case each of
the two chronographs would present a complete record of the beats
of both clocks.
All the results obtained are embodied in four tables, marked sever-
ally No. 10, No. 11, No. 12, and No. 13. Table No. 10 shows the
number of stars observed in common at both stations, the mean
difference of longitude by each clock, and the mean by both clocks.
Table No. 11 shows the number of clock connections made,-the
mean difference of longitude when either clock was beating through
the main line, the other being in the local circuit. Table No. 12 is
formed by regarding each mean of fifteen wires as a single arbitrary
signal, and determining the correct time at which that signal was
recorded at each of the stations, then the difference of those times
was equal to the difference of longitude. The table shows the num-
ber of such signals made during each night, the mean difference of
longitude as given by Detroit signals, by Goderich signals, and the
mean of these results. Table No. 13 embodies the results by the
several methods, and the consequent mean of all.
The tables No. 7, 8 and 9 are explanatory of the mode of forma-
tion of the foregoing. The mean of the results by the different
methods is assumed as the difference of longitude. This result is
not corrected for personal equation, which, however, is supposed to
be very small—probably not to exceed = 0°.03.
The observatory at Goderich stood 16.6 yards due South of the
North-East corner of lot No. 1265 of the town plat.
A difference will be noticed between the results obtained when
the electric current passed from East to West, and those obtained
when the current passed in the opposite direction. This difference
is nearly a constant one, as it appears in every case where a com-
parison is made, and as every observation has been rejected where
such a comparison could not be made, (that is, where a result could
not be had, obtained by passing the current in both directions,) there
are 213 such comparisons. A mean of all the differences amounts
to 0°,043, which is + when applied to the result of a signal passed
from East to West. This difference is undoubtedly due to the dif-
ference between the strength of the battery at Detroit and that at
Goderich, the latter possessing only a third of the former's strength,
which rendered impossible such an adjustment of the relay magnets
as would make the “pass-time” the same in amount, whether the
27
current passed East or West. It is highly probable that the least
result approximates more closely to the true difference of longitude,
since a magnified error, due to an excess in the value of the “pass-
time,” is there more nearly eliminated. The probable error of the
final result is very much smaller than the probable amount of the
personal equation. -
The length of the line from Detroit to Goderich, and the weakness
of the Goderich battery, rendered it difficult to work between the
two observatories, yet the results are extremely satisfactory, showing
the high value to be attached to this mode of determining differences
of longitude.
Every facility for the progress of the work was afforded by the
citizens of Goderich, all of whom took a deep interest in it. My
thanks are due to Mr. Cameron, the Mayor of the place, for official
courtesies, as well as the ground upon which to build the observatory.
For the final longitude of Goderich we have the following: -
Longitude of Detroit, West from Greenwich, (see Annual Report
1859,) - - - - - - - - 5h 32* 108.247
Diff longitude between Detroit and Goderich, — Oh 0.5m 208.968
Longitude of Goderich Observatory West from
Greenwich, in time, - - - - - 5h 26m 498,279
Or in arc, º - º- - * *- - 81° 42' 197.185
. I desire to return my thanks to Lieut. R. F. Beckham, Top. Eng’rs,
and to Assistants Carr and Austin, who have always promptly and
efficiently assisted me.
All of which is respectfully submitted,
ORLANDO M. POE,
First Lieut. Top'l Eng’rs.

The difference of longitude between Goderich and Cove Island,
C. W., was determined by twelve chronometric expeditions, the re-
sults of which are given in the following table, marked No. 17:
The expeditions commenced on the 26th of June, and ended on the
18th of July, having been interrupted, between the 30th June and
the 12th July, by an accident which happened the steamer Search,
engaged in carrying the chronometers. Twelve chronometers were
used, and the twelve expeditions furnished 129 satisfactory com-
parisons, from which was deduced the mean difference of longitude
equal to 5.625 Cove Island West of Goderich.
For the longitude of Cove Island Observatory we therefore have :

Jongitude of Mackinac Observatory.
The difference of longitude between Cove Island and Mackinac
was determined by transporting twelve chronometers through four-
teen trips. One chronometer (No. 1485, by Parkinson & Frodsham)
not having given satisfactory results, was entirely rejected, and also
Seventeen single results, (marked in the accompanying table, No. 19,
by a dash;) thus making the difference of longitude depend upon
137 separate determinations, the mean of which is assumed as the
difference of longitude, and is equal to 11". 31.397, Mackinac West
of Cove Island; having a probableerror of + 0.024. This result
should be a close one, as the trips were made during very favorable
weather, and without any interruption from the beginning, on the
14th of August, to the end, on the 28th of the same month.
The difference of longitude between Fort Holmes (Station C. of
the Triangulation of the Straits) and the Observatory is 0°, 645, Fort
Holmes East of the Observatory; then
Longitude of Cove Island Observatory = 5h 26" 54°. 904.

Final Longitude of Fort Holmes.
Longitude of Fort Holmes, via the Eastern
Shore of Lake Huron, 5.38m25%. 656
Longitude of Fort Holmes, via the Western
Shore, - • 5 38 25. 077
Difference, OS. 579,
From the probable errors of the several determinations we find, that
the weight of the Eastern Shore longitude is to that by the Western
Shore as 24 is to 1. Then the mean of the two results, giving to each
its proper weight, is found to be 5". 38". 25°. 633, or in arc, 84°. 36'.
24". 482.
The longitude of Fort Holmes, as determined by Moon Culmina-
tions, and which has been used heretofore, is 84° 32' 17". 45; the
difference is therefore, --4' 07". 032, to be applied to all of Lieut.
Raynolds’ Longitudes.
The difference between the final Longitude of Fort Holmes and
that determined by the Western Shore, is equal to 8"332 = 0°. 556,
which is distributed among the several determinations, in proportion
to their probable errors, as follows: *
Between Detroit and Fort Gratiot, + 0". 630 = +08. 042
Between Fort Gratiot and Forestville, 0 - 660 = 0 . O44.
Between Forestville and Sand Point, 2.475 = 0.165
Between Sand Point and Thunder Bay Is'd, 2.490 = 0.166
Between Thunder Bay Isld and Presqu’ile, 0.595 = 0.040
Between Presqu’ile and Bluffs, () . 595 = 0 . 040
Between Bluffs and Mast, 0 , 585 F () . 039
Between Mast and Fort Holmes, 0 - 302 = 0 . O20
Sum, +8". 332 = 0 , 556
-s-
The corresponding difference for the Eastern Shore is distributed
in a similar manner between Goderich and Mackinac, as follows:
Between Goderich and Cove Island, — 0". 165 = — 0°. 011
Between Cove Island and Mackinac, — 0 . 180 = – 0 . 012
Sum, - 0". 345 = — 0.023
Or applying the foregoing corrections, we have the following
corrected Longitudes:

Difference of Longitude between Detroit, Mich., and Ann Arbor, Mich.
The points connected were the Lake Survey Observatory, at De-
troit, and the Observatory of the University of Michigan, at Ann
Arbor. The signals were passed between the Detroit Observatory,
and the Railroad Depot, at Ann Arbor, at which latter place the
times of the signals were recorded, by noticing the time shown by a
sidereal chronometer, when the click of the magnet was heard. The
chronometer had been compared with the Observatory clock, before
being taken to the depot, and again, when returned to the Observa-
tory. The chronometer rate used was that which it had between
the two comparisons on the same night. The signals were recorded
at Detroit, upon a Bond chronograph; arbitrary signals were sent
each way in sets of twelve, and the mean of each set was consid-
ered as one signal. The performance of the telegraph was all that
could have been desired. Unfortunately, the weather is reported to
have been unfavorable for observing star transits, at Ann Arbor,
during the operations, so that the error of the clock on the two
nights upon which a connection was had, was not as well determined
as I could have wished.
The Observatious were made, and the time of signals recorded at
Ann Arbor, by Prof. James C. Watson. The observations at Detroit
were made by myself, assisted by Mr. James Carr. The following
table shows the results. -

A PPEN DIX No. 2.
OFFICE SURVEY N. & N. W. LAREs, -
S Detroit, Mich., April 24, 1860.
IR – -
I have the honor of reporting, that the meteorological ob-
servations you placed in my hands have been reduced.
Guyot's Tables have been used in making these reductions. The
elements determined were, the total pressure, or the barometer read-
ings reduced to the temperature of 32° Farenheit; the gaseous pres-
sure, or the total pressure minus the elasticity; the mean daily tem-
perature, elasticity, and humidity of the atmosphere ; the resultant
Velocity of the wind in miles per hour; the resultant direction of the
same ; and the amount of cloudiness, rain, and snow.
According to your instructions, I drew up a sheet headed with the
name of the place of observation, its latitude, longitude, and height
above the lake on whose shores the place is situated. This sheet
* columns for the date, and each of the elements referred to
3, OOVé. -
In the column of remarks I have placed the greatest and least
mean daily pressure, temperature, elasticity, and humidity, as well
as their monthly range. I have also given in this column the time of
highest and lowest wind, and the number of days of rain and snow.
The monthly means were obtained and placed in their appropriate
columns. I made out yearly sheets for Thunder Bay Island, and Ot-
tawa Point, Mich.; these being the only places at which there were
enough observations. -
All the reductions are very simple, except those of the wind. By
your direction these were treated as follows: the daily observations
of the direction and estimated force, being 4 in number, at equal
intervals of 3 hours, were considered as independent forces, acting
at the same time, and their resultant intensity and direction com-
puted by the ordinary formula of the parallelogram of forces. As
these forces were not acting simultaneously, but in succession, on the
body of the atmosphere, their resultant required a consequent reduc-
tion. That is to say, assuming them to have acted for 3 hours to-
gether, in the manner they were observed to have acted for 12 hours
separately, the resultant obtained on the first supposition should be
divided by 4, to obtain the resultant that would produce the same
effect in 12 hours. The quantities in the subjoined tables marked
daily resultants were obtained by the above method.
In getting the resultant velocity and direction for the month, a
method somewhat different was employed. All the daily resultants
between N. W. and N. E. were regarded as North, those between N.
E. and S. E. as East, those between S. E. and S. W. as South, and
those between S. W. and N. W. as West. The daily resultants being
thus classified, the sum of the intensities of all those from the
North, was taken and divided by the number of resultants from
55
that direction ; the same was done with those from the East, South,
and West, thus giving weight to each direction in proportion to the
number of daily resultants from that direction. If the resultant was
from either of the points N. W., N. E., S. W., or S. E., it was re-
solved into its components and each treated as a daily resultant. The
difference between the sums of the intensities of the northern and
southern daily resultants being taken, and also the difference between
the eastern and western resultants, two quantities are obtained with
the preponderating intensities and directions, which are regarded as
components of the final or monthly resultant.
One hundred and forty monthly sheets were filled, and yearly
sheets for each place were carried as far forward as the reductions
were completed, that is to the 1st of January, 1860.
My thanks are due Lieut. R. F. Beckham, Top. Eng’rs, and Assts.
James Carr and E. P. Austin, for valuable aid in the work upon
which I have just reported.
* Very respectfully, sir,
Your obedient servant,
WM. PROCTOR SMITH,
Lieut Top. Eng’rs.
CAPT. GEORGE G. MEADE, ToP'L ENGINEERs,
Supt. Survey W. and N. W. Lakes.
