scends to the edge of the surrounding plain on all sides and sends 

 several wooded prolongations downward, in canyons, several miles 

 across the bare plains toward the San Pedro Eiver. The principal 

 canyons on the east side of the range contain spring- fed streams of 

 clear, cold water — the best that we found between the Coast Range 

 and the Rio Grande. The stream in Tanners Canyon contains fish.

I was on the summit of Hasslops Peak (altitude 2,887 kilometers, 

 or 9,472 feet) October 21 and 26, 1892 ; also July 31 and October 17, 

 1893. During October, 1892, and July, 1893, I explored the whole 

 east side of the range from Igos Ranch on the north to Monument 

 102 on the south. This field appeared to be so rich that, in July, 

 1893, it was decided to detach Mr. Holzner from the Monument- 

 Building Party, which was necessarily accompanied by myself, from 

 the San Pedro River (Monument No. 98) eastward to the eastern 

 end of the boundary parallel 31° 20' (Monument No. 53), a region 

 that had been previously explored, in order to have him run a careful 

 line from the base to the summit of the Huachuca Mountains, which 

 he accomplished satisfactorily between July 24 and October 10, 1893. 

 In this, great assistance was rendered by the commanding oificers 

 and post surgeon (Maj. Timothy E. Wilcox) at Fort Huachuca. 

 Mr. Holzner's first camp was established near the lower timber line, 

 in Tanners Canyon, where the " post garden " is situated, on July 

 24, 1893. His line of mammal traps was gradually extended upward 

 through Tanners Canyon to the post sawmill, to which point his 

 camp was moved in August. From this point trapping was ex- 

 tended to the summit of the range, and his camp was again moved 

 from the sawmill to a spring near the summit of a high peak, which 

 overlooks Ramsey Canyon, on September 10. On September 30, 

 1893, the weather having become severely cold at the summit, Mr. 

 Holzner's camp was removed to the post garden, in Tanners Canyon, 

 where he remained until October 10, 1893, when he rejoined the 

 writer at Fort Huachuca. Camps were made at the Post Spring, 

 near Fort Huachuca, and at Frauds Ranch, in Millers Canyon, from 

 October 10 to 18, 1893. A complete circuit of these mountains was 

 made, and collections made on all sides of the range. Mr. Holzner 

 collected 207 mammals, 315 birds, and a few plants and land shells 

 in the Huachuca Mountains, between July 24 and October 9, 1893. 

 His work showed commendable enterprise and industry. 



Flora of Huachuca Mountains. — Much effort was devoted to col- 

 lecting and studying the fauna and flora of these mountains by 

 Major Timothy E. Wilcox, who was for several years stationed at 

 Fort Huachuca, and whose name must ever be associated with the 

 botany of the western part of the United States. The elaborate list 

 by N. L. Britton and T. H. Kearney, jr., and the collections made by
