CAMBRIDGE, September 24, 1877. 
We are just back via Niagara; Hooker and I via 
New York, and the former having the Sunday with 
Eaton at New Haven. All well and happy to get 
home after a prosperous and, as you may imagine, 
laborious journey of ten and a half weeks. The trip 
to Shasta involved long stagecoach journeys, but they 
were most interesting. Returning to Sacramento we 
went on to Truckee, where Lemmon ? joined us by ap- 
pointment. We gave one day to Mount Stanford and 
one to Tahoe, then took the overland train as it came 
on at midnight, and thence had no stationary bed till 
we reached ‘Nag ara. And we live to tell the story! 
I want to ‘el you what we are led to think about 
Firs and Spruces. I will give in this my own opinions, 
which lie yet open, but are likely to settle down, ex- 
cept you convince me to the contrary on some points. 
Hooker comes to the same conclusions or nearly, but 
I will keep to my own only in this letter, and ask 
what you think of them, off-hand. Your reply will 
come to hand before Sir Joseph sails. . . .
