June 1 to 7, 1894. — On June 1 we moved the camp westward along 

 the Boundary, camping a short distance south of the line in Naeho- 

 guero Valley, in Lower California, where we remained until June 7, 

 when we proceeded to Campo, in San Diego County, California. 



June 8 to 21. 1894. — Desiring to see more of the mountains of the 

 Coast Range, we set out from Campo June 8 and proceeded north- 

 ward to Mr. J. M. Gray's ranch, where we passed the night, going on 

 June !> to the summit of the Laguna Mountains (Coast Range) and 

 camping at Campbell's Ranch. From June !> to -21 we were engaged 

 in exploring and making collections in the evergreen-clad forests 

 which cover the summits of these mountains. 



June 21 to 28, 1894. — On June 21, descending the Laguna Moun- 

 tains to the southward in the direction of Campo, Ave camped at 

 Thomas Cameron's ranch and remained there until June 23, when we 

 proceeded to Campo, and thence to the Tecate Valley, near the south- 

 eastern base of Tecate Mountain. On the Tecate River we were 

 encamped until June 28, and explored the Tecate Valley and Mount 

 Tecate. 



June 28 to July 3, 1894. — June 28 I went to San Isidro Ranch, in 

 Lower California, leaving Mr. Holzner and some of the men at 

 Tecate, with instructions to join me, which they did the following 

 day. This fruitful but deserted ranch, whose owners had been killed 

 by Indians, proved to be an ideal collecting ground. 



July 3 to ,9, 1894.— With regret we left San Isidro on July 3, and, 

 traveling by the Mexican road, crossed Cottonwood and Otay rivers 

 to El Nido, thence up Jamul Creek to an old date-palm tree, where 

 we camped and remained until July 0. 



July 9 to W, 1894. — On July we broke camp at the date palm on 

 Jamul Creek, crossed into the Otay Valley, and thence to the Otay 

 Mesa and town of Tijuana, making camp at the Pacific Ocean, on 

 the left bank of the Tijuana River, near the last Boundary Monument 

 (No. 258). On July 20 we left the Boundary Line at the mouth of 

 the Tijuana River, having explored the estuary of that river and the 

 ocean beaches for some distance in both directions, and marched to 

 San Diego, California. This was our base of operations until the 

 biological work was concluded. Here Mr. Frank X. Holzner left 

 the party, after having been identified with the field work of the 

 biological section of the survey from its beginning. 



July 20 to August 13. 189 \. — From San Diego the adjacent region 

 was explored, and excursions made to Ocean Beach, La Jolla, up the 

 valley of the San Diego River, to the old Spanish mission, and io the 

 mountains of the interior. In company with Lieut. Col. J. TV". 

 Barlow, Mrs. Barlow, and a small detachment of soldiers, we left 

 San Diego on August 3, and traveled west to Alpine, San Diego 

 County, California, where we camped until August 7, when we pro-
