MAMMALS OP THE MEXICAN BOUNDAEY. 13 



July 28 to August 30, 189£.—Leit Lang's Ranch July 28 for San 

 Bernardino Springs; camped for one night in Guadalupe Canyon, 

 arriving at San Bernardino July 29. This was our base camp until 

 September 11. 



August 31 to- September 10, 1892. — On August 31, rode to Cajon 

 Bonito Creek, near its junction with the San Bernardino River, in 

 Sonora, Mexico, camping there for the night and returning to San 

 Bernardino September 1, and remaining there until September 11. 



September 11, 1892. — Rode to Piedras Nigras, on the Agua Prieta, 

 in Sulphur Spring Valley, where we camped for the night. 



September IB to October 10, 1892. — On September 12, rode to Johns- 

 ton'^s Ranch, near Monument No. 90 and nearly south of Bisbee, Ari- 

 zona, which is distant about 11.3 kilometers, or 7 miles. This re- 

 mained our base camp until October 10. From here visits were made 

 to La Morita and the San Jose Mountains, in Sonora, and to Bisbee 

 and the Mule Mountains in Arizona. The season was unusually dry 

 and flowering plants were scarce. 



October 10 to November 1, 1892. — Camp was moved from John- 

 ston's ranch to the San Pedro River at Monument No. 98 on October 

 10. This was the base camp until November. The surrounding 

 country was explored, and trips were made to the summit of the 

 Huachuca Mountains (North Peak; altitude 2,771 meters or 9,091 

 feet) on October 21 and 26, 1892. 



November 1, 1892, to June 6, 1893. — ^Having been relieved from 

 duty with the Boundary Commission, and assigned to Fort Clark, 

 Kinney County, Texas, for station, I left the San Pedro River on 

 November 1 and arrived at Fort Clark on November 5, 1892, where 

 I remained on duty until June 6, 1893. Mr. Holzner continued 

 with the surveying party until Nogales was reached, December 

 10, 1892, when he was dropped from the rolls of the U. S. National 

 Museum until June 1, 1893, when he was again employed at my 

 request. My successor, First Lieut. Harlan E. McVay, Medical De- 

 partment, U. S. Army, subsequently collected plants, which were 

 added to the collection, but the season was late and the number 

 consequently small.. The specimens of trees from the Patagonia 

 Mountains, however, filled a gap in the collection. 



June 6 to July 3, 1893. — Having been ordered on temporary duty 

 to Fort Hancock, El Paso County, Texas, I left Fort Clark on June 

 6 and arrived at Fort Hancock on the following day, remaining 

 there until July 2, when I was relieved from duty at Fort Hancock 

 and started for Fort Clark, arriving July 3. While on temporary 

 duty at Fort Hancock some collections were made between there and 

 El Paso, Texas. 



July 3 to H, 1893. — Stationed at Fort Clark, Texas.
