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

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

Septeinher 12 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 imtil October 10. From here visits were made 

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

 and the Mule JNIountains 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 cam^D until November. The surrounding 

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

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

 feet) on October 21 and 26, 1892. 



November 1, 1892, to June 5, 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, Avhen 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

 duty at Fort Hancock some collections were made between there and 

 El Paso, Texas.
