 Original copies in printed paper covers are filrrad 
 beginning with the front cover and ending on 
 the last page with a printed or illustrated impres- 
 sion, or the back cover when appropriate. All

 lies hetween 12() and V2 ') matinitudes. 
 
 besides the telescoiK' a few other instruments, mostly for meteorological

 Medicine Hat is situated in the dry belt of Southern .Vlherla. ti.V) 
 miles west of W'imiipeii on tlie main line of the ('.1M{. d"he city ot 
 soniethin-;; less than l."),l)()(t jieople. lyiiij;; '"' 'l"- valley of the South 
 Saskatchewan, is noted for Us immense resources in natural M:as. In view 
 of (lie cheap jiower thus afforded it is claimed that here will lie the 
 maimfacturinsi' centre of western Canada. This would lie aside from our 
 discussion were it not that the vicinity of a mamifacliuini!; city i- ii-uall\- 
 considered a poor place to locate an astronomical oliM'rvatory. .\s there 
 is. however, no smoke from the use of ij:as it would seem that no drawback 
 would ther<'liy result. .\part from the railway trains, which use coal, it is 
 a smokek'ss city. 
 
 In lookinji o\er the place for a -\utable location for my telescooe I 
 
 decided Upon the talilelatid to the north cf the city. Its elevation above 
 
 the citv is about l;^."> feet and lietiee above sea level _'.;5()0 feet. To the 
 
 north and east and west stn>tches the |)latean. while inuncdiately to the

 As intimated ahove. unfavourahle weather ^iiceted me lieir. The 
 average total pivcipitation t'or the year is 14 C. ii.ehes, and durin- the two 
 wee'Ks I was here ahout one-sixth of that amount of rain iVIl in all, 
 there weir '.t iiifihis on wiiieh no work of any account could he <lone. .'. 
 nights which weie more <.r le>s cloudy pernuttin« some work lo be done 
 anil only one which could he called clear. 
 
 Xo rapid change, of the harometer were noted; the maximum raii^e 
 duriuK the two weeks vi-it was only O-.V. inche-. The avera-e velocity of 
 the wind was 10 N niih's j.er hour. .\s a rule tlu' wind dropped in the 
 evenin;:, thou^;h this rule was not without exception, 1 have iiote.l it 
 calm in the eveninti on commencing work and during the nitjht the wmd 
 would lis., an.i attain a velocity of 10 or 12 miles an hour. In such 
 cases it was necessary to u.se a wind shield to prevent undue jarriufi of 
 the telescoi)e. The jieneral direction of the wiml is east and west 
 following the valley of th<. river. Sometimes for short i)eriod^ of the day 
 it attained a velocity of from ."jO to (10 miles an liour. 
 
 The following remarks describe the conditions on the niRlUs ui)on which 
 work was done.

 Olympian momitains standinji out clear cut in the early evenin-, yet there 
 was considerable unsteadiness apart from the vibration^ (hie to the wind. 
 
 August 2(; While the steadiness was in p'ncfiil Ji'»'"'- ''"''''' "'''''" 
 bodily displacements of tii(> imasos ransiuK fro-n 0":^ to ()"o. Cot a 
 frlimpse of the 11-^. m a llorculis, hut on the whole it was not easy to 
 jiick iij) faint stars. .1 and ■', could bo known to be present from a certain 
 milkiness surrounding; their position, Imt th.ey were by no m(-ans i.rominent. 
 Considering that it just cleared entirelv about S o'clock I think the s.-einsi 
 was exceptional. Hated 4. 
 
 Auiiust 27. Day clear and calm and p'od niffht expected. Did not

 InuiKcs lacked clear cut definition

 I'eiitieton, tif-t vi-il, lli;;() feet, second \isil, 21M) feet; Victoria about 2()(t 
 feet. rrom ^''tn'ral unaided eye oliservations 1 had judyied that I'eiiticton 
 wa.- superior in this re.j;anl and the photofifaphic i)latcs indicate such to he 
 ,1,,. ca-e. The explanation of my apparently lii«h rating for Victoria in 
 this regard i- the foUowinu,-; Two things were taken into accumit in 
 assinninu u numl.er to reincscnt the transparency; d) the hi'ihtuI appearance 
 of the sky and the faint oliject- reached with the naked eye; (2) the ease 
 witii which faint objects could be picked up with the telescope. Now in 
 ,.,,jra,-,l to i'_'i Victoria excelled Penticton consideratily. Tlu' theoretical 
 limitini: ma'j;nitude for the telescope lies between l-'O and !_'■.'). Stars 
 of 11-.') ma^iiiilude coul'l I'l- picked up and persisted more or less in vision 
 almost every ni.^ht at Victoria, while sucli was not pos.-ibie at I'eiitieton on 
 more than half the iiifihts. Now tlie reason for this is no doubt the 
 o;reat.T steadiness experienced at the former place. The lisht from the faint 
 .ihjecl,- was concentrated into siiiail compass makiiifz; a distinct imiiression on 
 the eye, which could not be the case where the iiiia^e was not perfectly 
 delmed and -teady. Transparency, in s(j far as faint objects to be reached 
 is concerned, cannot be dissociated froir steadiness.

 are slifihtly less so in this respect than the winter but only slightly. .\ 
 summary of the hysroKrapbi'' sheets* from June to Xovemlier inclusive 
 shows that the humidity is least about 2 o'clock in the afternoon, when it 
 is (is. that it rises gradually to 94 about 2 o'clock in the morninji and 
 <'ontimies thus until about t; a.m. when it falls .somewhat more rapidly than
