OEGANIZATION OF THE JENNEY SUEVEY. 19 



March 26, 1875, to undertake the work of the examination, and Mr. Henry 

 Newton was commissioned to act as his assistant. 



At first it was proposed that with his assistant, and with the help of a 

 small force of miners and laborers, Mr. Jenney should immediately proceed 

 to the field, make in a few weeks a hasty examination, return, and make his 

 report. But as much of the value of the labor would be lost without a 

 reliable map of the region — that of Lieutenant Warren and General Ray- 

 nolds expressing only the outer rim of the Hills — it was finally arranged 

 to add to the party a topographer and an astronomer. Dr. V. T. McGilly- 

 cuddy, late of the Lake and Northern Boundary Surveys, and Capt. H. P. 

 Tuttle, late of the Cambridge Observatory, were therefore commissioned to 

 accompany the expedition, respectively as topographer and astronomer. 

 The personnel of the expedition, as finally organized, consisted of Walter P. 

 Jenney, E. M., geologist in charge; Henry Newton, E. M., assistant geolo- 

 gist; V. T. McGillycuddy, M. D., topographer; Captain Horace P. Tuttle, 

 A. M., astronomer; C. G. Newberry, M. D., assistant astronomer and natur- 

 alist;* W. F. Patrick, E. M., and the following corps of miners and laborers: 

 John Brown, jr. ; William H. Root, head mining assistant; William 0. Bald- 

 win, A. J. Bottsford, A. P. Sanders, T. H. Mallory, Thomas Morey, James 

 Conklin, Robert M. Jones, A. E. Guerin, and George Bowlin, cook. 



With all possible haste the plans were matured and the necessary in- 

 struments and tools purchased, and on April 25 the whole party assembled 

 at Cheyenne, Wyo. Here an unexpected delay was unfortunately forced 

 upon us, as the orders for the necessary means of transportation, wagons, 

 horses, &c, had not been issued by the War Department, as had been sup- 

 posed. The time, however, was spent in fitting out the numerous little 

 details of the expedition, and finally, on the 17th of May, all transportation, 

 &c. being fully provided for, Cheyenne was left behind. Arriving at Fort 

 Laramie on May 20 all arrangements were consummated; and crossing the 

 Platte on the afternoon of the 24th of May we joined the military escort 

 furnished by the War Department, consisting of Lieut. Col. R. I. Dodge, 

 Twenty-third Infantry, commanding; Lieut. M. F. Foot, Ninth Infantry, 



* From ill health Dr. Newberry was unfortunately compelled to resign at Fort Laramie on the eve 

 of departure.
