QOODE ACCOUNT OF OPERATIONS. 1!) 
be used in connection with the work. The party was organized a1 
Spokane, and a1 first consisted of only a packer and a cook, bul was 
afterwards Increased by the addition of a field assistant, when angle 
observations were begun. When occasion required, for instance in 
clearing the timber for a triangulation station, extra men were hired 
by the day. Transportation was a1 first by saddle and pack animals 
alone, bul Later a light# spring wagon was added to the outfit. 
The work was greatly retarded by smoke during the summer, which 
was at times so dense as to render observations impossible; and by 
unusually early storms in the fall. All operations were entirely 
suspended about October 1, the snow being so deep as to render prac- 
tically Impossible the ascent of the peaks used as triangulation 
stations. The season's work consisted in extending the triangulation 
from the Spokane base eastward, through a longitudinal interval of 
about 70 miles, to the boundary line. Fifteen stations were erected, 
nine of which were occupied, and one observation for azimuth was 
made. Another object accomplished during the field season was the 
identification on the ground of the Mooyie Trail monument, which 
had been established by the Northwestern Boundary Commission. 
This monument was about 8.1 miles west of the boundary line between 
Idaho and Montana, and was the nearest monument or mark of any 
kind on or near the international boundary that could be identified, 
i Further reference will be made to the Mooyie Trail monument. 
After the party was disbanded, Mr. Perkins proceeded to California 
for duty. During the winter the office work pertaining to the tri- 
angulation was done under the direction of Mr. S. S. Gannett. Three 
figures were adjusted by least squares, and the geodetic positions of 
nine points were computed. One of the stations, Divide, was found 
to be 6,072 feel cast of the Idaho-Montana boundary line, and another 
station, Scotchman, was found to be 7,842 feet west of it. 
Field operations were resumed in June, L898, two parties being 
organized, one for the extension and completion of the necessary tri- 
angulation, the other for running the random line northward from 
the point determined as the intersection of the thirty-ninth meridian 
west from Washington with the crest of the Bitterroot Mountains. 
Mr. Perkins continued the triangulation, and the Line party was 
organized by Mr. S. S. Gannett, topographer, with Mr. I). L. Reaburn, 
as transit man, t he Latter assuming charge of the party after the work 
was started. 
Mr. Perkins extended his work of the preceding year northward to 
the international boundary, occupying nine new stations and reoccu- 
pying four old ones. A high signal was creeled over the Mooyie 
Trail monument, and this point was located. Unfortunately the 
character of the country was such that il was impossible to get a 
location by triangulation near the northern terminus of the inter- 
state boundary line.
