670 TRAVEL IN EUROPE AND AMERICA. [1877, 
at sea in his, and would hardly be convinced by my 
arguments. But he tells me he is convinced by yours. 
October 19. 
... Our journey of ten and a half weeks, with 
Hooker, was a most enjoyable one, every way pros- 
perous, but laborious. Colorado to the borders of 
New Mexico, a little of Utah and the Wahsatch moun- 
_tains, and extensive traveling in California, as far 
south as Monterey, and north to Mt. Shasta. On 
return, I had Hooker's copious collections to name up. 
I made only small and special+ collections, and most 
busy we were kept till, on the 6th inst., I put 
Hooker on the steamer, which, as telegraph tells us, 
only yesterday reached Queenstown, so he will be 
landing at Liverpool to-day, —a full fortnight from 
Boston to London. I am now busy enough with 
bringing up arrears of correspondence and affairs, and 
studying some collections which will not wait. Only 
by the end of this month shall I get to resume my 
regular, but long, interrupted work. Mrs. Gray ac- 
companied us, and enjoyed it much, enduring well the 
occasional camp life and such hardship as there was. 
You should come over, and we will repeat the journey, 
but only three years hence. Much as I should enjoy 
it, I cannot spare the time sooner. 
I found myself quite equal to younger people in 
mountain climbing. .. .

CaMBRIDGE, July 4, 1877. 
Dear OLD E.,— Never mind if you are seventy; 
Hooker is sixty, and I am between, and we are lively 
“yet.
