134 CONTRIBUTIONS TO WESTERN BOTANY 
tall went down the river to Astoria. From here he sailed for California, 
finally reaching San Diego, where he remained for some time botanizing. 
e then went by boat to the Sandwich Islands and back to the Atlantic 
coast by way of Panama. This monumental trip was the most productive 
of new species and new genera of any of the transcontinental trips, and 
yet it did not cover more than one fourth as much territory as I have 
covered in my botanizing. But it was made by slow wagon travel, while 
I have traveled over Nuttall’s route several times by auto or train through 
Wyoming and west, botanizing at critical places on the way, and visiting 
many of Nuttall’s type places. 
er this time the Government sent out many exploring parties 
equipped for botanical work. Gray, who was a pupil of Torrey’s in the 
early days, naturally shared with Torrey the naming of the botanical 
material. Together they got out also the Report on the Mexican Boun- 
dary Survey. 
When Nuttall returned from the west with all his collections, he 
Philadelphia Society. He continued his relations with that body until 
his death. It is evident that he had some plans about getting out a flora 
of the United States, for in 1818 he published his Genera of North 
America, and in 1842 his Trees of North America. Just what was the 
cause of his hostility to Gray is not known, but professional jealousy 
was not unknown in those days when Rafinesque was making himself 
odious by his publications. The fact remains that Nuttall did not at 
all like Torrey and Gray’s handling of his new species and genera in 
their Flora of North America. That Nuttall regarded Gray as an up- 
start was evident, for Gray was 24 years younger than he. Yet so far as 
I can find out Gray never entered into any controversy with Nuttall, but 
y with men who were younger than he. Gray was a savage partisan 
and did not hesitate to try to crush them. 
In his later years Torrey deposited all his types in the herbarium at 
Columbia, which school was to become his botanical executor. The

he would devote the rest of his life to undoing the work of Gray, con-
