670 TRA VEL 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 hist., 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.
