(3,760 feet), the height of Mountain Camp is 11,624; 

 using Gannett's height of Lone Pine (3,661 feet), Moun- 

 tain Camp is 11,525. Professor Langley makes Mountain 

 Camp 11,625. 



From the above, I should say that the approximate 

 heights are: Lone Pine (Gannett), 3,661; Mountain 

 Camp (Gannett and Langley), reduced by me, 11,525; 

 Mt. Whitney (Gannett and Langley), reduced by me, 

 14423. 



I should, therefore, suggest that the adopted height 

 of Mt. Whitney be about 14,423 feet, as determined by 

 using Professor Langley's observations and Professor 

 Gannett' s height in 1900 for Lone Pine.*

COMPUTATION OF THE ALTITUDE OF MT. WHITNEY. 



Under date of January 11, 1904, Professor Joseph N. 



Le Conte, of the University of California, says : — 



" The Lone Pine railroad station is on the main line of the 

 Carson and Colorado Railroad, and is on the eastern side of 

 Owens River, close to the base of the Inyo Range. The town of 

 Lone Pine is on the western side of the valley and on the 

 western side of the river also. The distance between the two 

 points is about three miles, and the railroad station bears about 

 north 60° east of the town. I visited the raihoad station last 

 September and spent some time with Mr. McGrath, the division 

 superintendent. His memory of the altitude of the rail at the 

 station, namely, 3,658 feet, was afterward corroborated in a letter 

 from him to me after consulting the records of the survey at 

 Carson City, Nev. Mr. Henry Gannett gives the same number in 

 his " Dictionary of Altitudes," evidently obtained from the same 

 source. This, however, is not the altitude of the point occupied 

 by Professor Langley in his determination of the height of Mt. 



* A letter from Professor McAdie makes it very doubtful whether the hamlet 

 " Lone Pine," occupied by Professor Langley in i88r, is the same as the railroad 

 station "Lone Pine," subsequently established.
