. 66.] TO GEORGE ENGELMANN. 671 



Perhaps we young fellows may knock about rather 

 faster than you like, wanting to do much in a little 

 time. But then, you need not do so much in Colorado 

 as we ; take the easy part. ... I shall be sorry if you 

 fail us. 



We must twine in Cuscuta, as we twine in the rest 

 of the book. For real accuracy we must finally come 

 to the terms I propose, entropic and antitropic. We 

 can't get watch-hands into a good form for the de- 

 scription of order, genus, etc. 



Be sure I '11 keep you posted. Should like to go to 

 Iron Mountain. 



WAITIKG ON RAILROAD FROM CANON CITY 

 TO PUEBLO, July 21, 1877. 



... If this flowering Euphorbia is the one you 

 asked for I have made good specimens. The round- 

 leaved one is on the hills, and is not yet out ; is not 

 the one, I am sure. 



We had yesterday a good day (with Brandegee) 1 

 at the Arkansas Canon ; it is grand, surely. 



To-day Hooker and the Stracheys drive across and 

 down Wet Mountain Valley to La Veta (two long 

 days), while we, Mrs. Gray, Dr. Hayden, and I, re- 

 turn by railroad to Pueblo, and thence to La Veta, by 

 sunset to-day. To-morrow up to a camp on La Veta 

 Pass of Sangre de Christo Mountains, which Captain 

 Stevenson is preparing. 



Our English friends begin already to feel in a 

 hurry, and for a wonder I am the hold-back member 

 of the party. . . .

 Washington territories and the Northern Pacific. At present living 

 in San Francisco.
