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

 .several wooded prolongations downward, in canyons, several miles 

 across the bare j^lains toAvard the San Pedro River. 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 ^Ir. Holzner from the Monument- 

 Building Party, which was necessarily accompanied b}^ myself, from 

 the San Pedro River (Monument No. 98) eastAvard 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, Avhich 

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

 In this, great assistance was rendered by the commanding officers 

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

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

 iji Tanners Canyon, Avhere the " post garden " is situated, on July 

 24, 1893. His line of mammal traps Avas gradually extended upAvard 

 through Tanners Canyon to the post saAvmill, to Avhich point his 

 camp was mo\'ed in August. From this point trapping Avas ex- 

 tended to the summit of the range, and his camp Avas again moA-ed 

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

 OA^erlooks Ramsey CauA'on, on September 10. On September 30, 

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

 Holzner's camp Avas remoA^ed to the post garden, in Tanners Canyon, 

 Avhere he remained until October 10, 1893, Avhen he rejoined the 

 Avriter at Fort Huachuca. Camps Avere 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 Avas 

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

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

 in the Huachuca Mountains, betAA^een July 24 and October 9, 1893. 

 His Avork shoAved commendable enterprise and industry-
