table or absolute, although they come undoubtedly a great deal nearer 

 truth than any determinations of heights made by previous surveys in 

 this region or others adjacent to it, as their respective base barometers 

 were too distant, and recently discovered discrepancies in railroad levels 

 made corrections necessary which changed the results over 100 feet 

 from previously assumed elevations throughout the Eocky Mountain re- 

 gion. 



Notwithstanding the more generally correct determinations of altitudes 

 of many points and places all over the region within the Eocky Mount- 

 ain system, the difficulty of obtaining absolutely correct elevations is not 

 removed when the time for field observation is but short, the tempera- 

 ture and climate being variable during that short period. 



Our results of elevation aie partially derived from observations with 

 the cistern barometer and partially from corrected aneroid readings, 

 while vertical angles have also assisted in the determination of the gen- 

 eral heights of this country. These, at least, for all practicable pur- 

 poses, are satisfactory, while to obtain real scientific accuracy i'n the 

 results would require a much longer time of observation. 



In conclusion,! wish simply to add, that in thesurvey of our district we 

 followed that method of work which has been uniformly adopted by the 

 various field parties of the survey for several previous years. ,, 



Within this district stations were made on thirty-five of the highest 

 points, and observations for both geodetic and topographic purposes 

 were made thereon, while six auxiliary stations were made to supple- 

 ment the work in necessary places.
