years and at Colville depot during eighteen months, furnishing corres- 

 ponding observations for the barometrical readings taken by the diflferent 

 parlies' along the line and other routes of travel, thus affording the 

 material not only for a report on the Meteorology of the country, but also 

 for barometrical profiles of the different routes/ The work will also be 

 illustrated by a number of views, showing the physical character of the 

 country. 



During the progress of the work the eclipse of the sun of July 13th. 

 1860, occurred, and every exertion was made to secure observations as 

 complete as possible, with a view not only to the difference of loiigitiule 

 along the line, but also to their value as a contribution to science. As tue 

 eclipse occurred early in the working season, and the parties were at that 

 time in the most rugged portion of the country, it was with great diffi- 

 culty that they could reach suitable points on the boundary in time. 

 However, the two astronomical parties were able to get in position, but 

 on account of an unavoidable accident to some of the delicate instruments, 

 only one of the parties succeeded in obtaining observations, and these 

 were made at Camp Mooyie in approximate Ion. 116° 10'^ west <»
