measured. Starting out from Carter's station, and using the 

 height given by the Union Pacific Railroad (6530 feet), we as- 

 certained the height of Fort Bridger to be 6714. 8 feet. Then 

 by a series of half-day corresponding observations and com- 

 parisons we moved on up into the mountains, heading to- 

 ward Gilbert's Meadow, which, although we found it a good 

 camping place, was not a point for active work, and hence we 

 had to move on to a camp at the head of the west branch of 

 Smith's Fork. We remained there till the place of our day's 

 work became too far off for us to reach it comfortably. We 

 then moved to the centre of the East Branch of Smith's 

 Fork's valley, upon one side of which we had been working. 

 From this base we operated most successfully, till we were 

 forced to make our way back on account of the storms which 

 occurred daily. We weat back slowly, verifying our work, 

 and returned to Fort Bridger to find our circle of elevations 

 come to a close within two feet. Although the result may 

 be an accident, still this speaks for itself. The barometric 

 bases measured were as follows :
