 accessible, but the records are probably in the office of the 

 Chief of Engineers, U. S. Army. 



" It is," says Wheeler, " the highest point measured by 

 careful barometric observations within the territory of 

 the United States, except Alaska." 



The record of the observations made by Rabe in 1873, 

 with the barometer. Green No. 1554, is as follows: —

Reduction to standard temperature. 



These readings, corrected for temperature only, differ 

 from the values obtained by us, by +0.217 inches. The 

 difference from the readings of the other barometer 

 (Green No. 1664) was + 0.205 inches. 



It will be noticed that in the readings made in 1903 

 there is a decrease in temperature during the obser- 

 vations, as shown by both attached thermometers, and 

 moreover the temperatures themselves are not similar. 

 Barometer No. 1554 is a small mountain barometer with 

 a scale reading from twenty-four to eleven inches. Ba- 

 rometer No. 1664 has a scale reading from thirty-three 

 to fourteen inches. Both instruments were filled with 

 clean mercury June 23, 1903, and the longer instrument 

 carefully read and compared with station barometer No.
