GEOLOGICAL SURVEY OF THE TERRITORIES.

of the peaks seemed perfectly covered with them, hardly a square inch 

 being seen that did not bear some brilliantly-colored speci)iien. They 

 seemed to grow in greater abundance and more brilliancy of color on 

 basaltic rock than on granite. Specimens were obtained mostly late in 

 the season, and rather a large collection was secured. They were sent 

 to Henry Willey, esq., ]!^ew Bedford, Massachusetts, and he deserves 

 great credit for the prompt and accurate manner in which he worked them 

 up. The number of species collected, including their several varieties, 

 is sixty-seven, all of which are mounted and labeled. 



Fungi occurred in considerable abundance, but as no conveniences 

 for preserving them were jjrovided, but a small collection could be made. 

 They were sent to Charles H. Peck, Albany, New York, who has done 

 more than could be expected with the very indifferent material sent to 

 him. The fleshy fungi are hard subjects to deal with in the field, and 

 several expedients were resorted to for preserving them. An attempt 

 was made to preserve them by pressing sections, but it was found im- 

 possible to keep them from gluing themselves to the paper suitable for 

 pressing flowers, and thus ruining specimens. The very few that I 

 did succeed in bringing home in this manner could not be determined. 

 The list of fungi therefore is rather small, although containing two new 

 species. This is a group that has never been thoroughlj^ examined in 

 the West, and I have no doubt that a close scientific investigation 

 would disclose hundreds of species new to science. A wide and an in- 

 teresting field is here laid open to the mycologist. 



For the convenieijce of those interested in comparing the flora of the 

 eastern and western slopes, I add here three tables compiled from the 

 collections made in 1871 and 1872. Having but the work of two seasons 

 as material, the tables are, to a certain extent, necessarily imperfect, and 

 future collections will make many corrections, but they will 'serve to 

 show the general distinctions. None of the plants peculiar to the Great 

 Salt Lake Basin are included. No attempt was made to include the 

 Cryptogamia, as they are not sufficiently known. It will be remembered 

 that collections were made on the E-ocky Mountain slojaes between lati- 

 tude 430 and 46°.
