LIST OF PARTY.—COLLECTION OF MATERIAL, &C. 3 
PREPARATIONS FOR THE SURVEY. 
Among the first of the preliminary duties required by the preceding instructions, were the 
organization of a party, and the collection of the necessary surveying instruments. The former 
was soon effected. So great was the number of applicants to the War Department for this work, 
that the services of many who had been most highly recommended were necessarily declined. 
The following is a list of those employed

A portion of the instruments required for our operations it was found a matter of great diffi- 
culty to obtain, in consequence of the recent outfit of parties for scientific explorations. Com- 
modore Perry had just gone upon his mission to Japan ; Captain Ringgold was completing his 
preparations to explore in the North Pacific ocean; Dr. Kane was in readiness to recommence 
his search for the lost ship of Sir John Franklin; and Governor Stevens, in charge of a party 
to examine the northern route for a Pacific railroad, had secured the few instruments of the 
kind referred to which the others had left. Every portable transit, magnetometer, and barom- 
eter, that could: have been purchased in the shops, or borrowed from scientific societies and 
observatories, had been already appropriated for one or the other of these expeditions. The ordi- 
nary surveying and astronomical instruments were, as usual, furnished by the Topographical 
Bureau; but barometers we were obliged to have made for the occasion, and it was necessary to 
wait antil they could be completed. 
The needful preparations for transportation and subsistence were meanwhile progressing. 
In these operations we were greatly indebted to the Quartermaster General’s department, for 
the aid and facilities it afforded. Major Crossman, at Philadelphia, gave the matter his per- 
sonal attention, and in less than two weeks our wagons, tents, &c., were constructed and 
delivered to the railroad company for transportation to Cincinnati. In order that no time should 
be lost, Lieut. Ives immediately set out for New Mexico, by the way of San Antonio, Texas, and 
aso. At the latter place were a few astronomical, magnetic, and meteorological instru- 
ments, which having been deposited there by the Iodoa Boundary Commission, were placed at 
our disposal by the honorable Secretary of the Interior. Having obtained these, fond Ives was 
instructed to repair to Albuquerque, and there await the arrival of the main party; making, 
meanwhile, astronomical, magnetic, and meteorological observations, obtaining information of 
the country beyond, and completing such preparations as should Els our progress west- 
ward from that place. 
On the 29th of May, the last division of the party left Washington for the Mississippi river 
and the frontier; a portion going by the way of New York city, in order to obtain the instru- 
ments that were there being completed. We then hastily proceeded to Cincinnati, where Lieu- 
* Mr. Jones was taken ill soon after leaving Fort Smith, and was obliged to leave the party 2 return home. Mr. Abner C. 
Gaines, of Oregon, was then appointed to the vacancy, but served only a short time, when, for the same cause, he was com- - 
pelled to resign. db 5
