urements in 1860 are reported to have given the height of Mt. 
Hood as 11,934 feet. 
Mt. St. Elias has generally been considered the highest 
mountain in North America on the authority of Malespina’s 
manuscripts, discovered by Humboldt in the archives of Mex: 
ico, which assign to it an elevation of 17 ,854 feet. The follow- 
ing circumstances, in the view of Prof. Whitney, justify us in 
believing that Malespina’s measurements were grossly incorrect, 
“In the first place,” he remarks, “La Perouse measured this mountain 
in 1786-8, and made it only 12,661 feet high; again, on the English 
Hydrographical Charts, it is given at 14,970 feet. But, secondly, Van- 
viz: 16,000 and 16,750 feet. But, it may be said with truth, that these 
figures given by Douglas are of little value, and that they aré considerably 
above the real heights,
