Elevation of Pike's Peak. 



I am greatly indebted to Mr. E. S. IST^ettleton, civil engineer, for a re- 

 port dated June 29, 1874, of a line of levels which lie has just run from 

 a D. & li. G. E. W. bench at Colorado Springs to the exact summit of 

 Pike's Peak. The line was run on the request of Gen. Albert J. Meyer, 

 Chief Signal- Officer, TJ. S. A., and at the expense of the War Depart- 

 ment, for determining the elevation of the United States Signal-Office 

 meteorological station, which is situated on the summit of the peak.

 of our barometric station situated near the top of the peak. The fol- 

 lowing are the results of this line of railroad levels :
