• I was gratified to learn from Dr. Parry, that the actual survey of the 

 route from Station 50 to Berthoud's Pass has proved the approximate ac- 

 curacy of our barometrical results. Gen. Case found, by levelling;, the 

 difference between both points (distance 6 miles), 2,634 feet; the barom- 

 eter made it 2,656 feet, or only 22 feet higher. 



f On the northern slope the trees seem to attain a higher elevation than 

 on other exposures, here as well as in some other mountain chains. 



J Torrey's Peak, in the same Snowy Range, is as high or a little higher.
