These escorts were ( with the exception of one corporal and six men, with Lieutenant floxie, detailed from the military department of the Platte, General E. O. C. Ord commanding) drawn from the military department of the Missouri, General John Pope commanding, the larger portion of the latter having been detailed from the military district of New Mexico, Col.

These escorts were distributed among the several working field- parties, aud were in numbers sufficient only for the protection of the lives of the members of the expedition and for guardiug the public property. The necessary number of guides, packers, herders, laborers, & c, accompanied the expedition. The Denver division, or Colorado party, under Lieut. W. L.

UNITED STATES ENGINEER OFFICE, GEOGRAPHICAL EXPLORATIONS AND SURVEYS WEST OF ONE HUNDREDTH MERIDIAN, Washington, D. ft, January 1,1874. SIR: 1 have the honor to submit the following executive report of operations under my charge during the field season of 1873: The party to which I was assigned as executive officer in charge was organized at Salt Lake City, Utah, and consisted of Gilbert Thompson, topographer; Edwin E. Howell, geologist; William Sorners, meteorologist; Alexander Brown, odometer recorder; one cook, one cargadore, and four packers, with an escort of one sergeant and five privates from the military Post of Beaver, Utah. The party left Salt Lake City on May 30th, and operated, until September 7th, east of the Wahsatch Mountains, in Castle Valley, working its way southward to the Colorado Eiver, over the western part of Castle Valley, the portion of country required to complete atlas sheets Nos. 50, 59, and 67, at that time prepaiing for publication. On the 7th of September we crossed the Colorado Eiver and proceeded by way of Oraybe and the Moquis Pueblos to Fort Wingate, N. Mex., whence, after refitting, we proceeded southward, cooperating with the other parties in New Mexico and Arizona Territories, and, returning at the close of the season, disbanded at Fort Wingate on the 25th of November. During the three months' operations in Utah about fifteen hundred topographical and triangulatiou stations were occupied, aud one thousand and twenty- five miles of meander lines measured, besides which numerous detours were made for the ascent of prominent points us triangulatiou stations. The latitude and departure of camp was computed each night, the meander lines of the day plotted, and the principal topographical features drawn upon the field- map. Sextant observations for latitude upon uorth and south stars, and observations on Polaris for maguetic declination, were taken at each camp. The meridian ot Provo was connected with that of the observatory at Salt Lake City, time- signals having been sent over the wires of the Deseret Compauy, freely tendered to the expedition by the courteous action of D. Milton Musser, superintendent. |
