82 TRIANGULATION AND SPIRIT LEVELING [bull. 175. 
where a closure of 0.146 feet was made with line brought west by Mr. 
E. L. Faison from South McAlester, Indian Territory, over the 
Choctaw, Oklahoma and Gulf Railroad. From Oklahoma City, Okla- 
homa Territory, Mr. R. Coe ran west over the Choctaw, Oklahoma 
and Gulf Railroad to Fort Reno, Oklahoma Territory, and then south 
from El Reno Junction, Oklahoma Territory, over the Chicago, Rock 
Island and Pacific Railway through Indian Territory to the Red River. 
Then returning a few miles north to the intersection of the railway 
with the first standard parallel south, of the Chickasaw Survey, he 
ran east along the said parallel to the Indian meridian, where he made 
a closure of 0.566 feet on the line of levels extended by Mr. J. H. 
Carlock westward from the Gulf, Colorado and Santa Fe Railwa}^ to 
the Indian meridian. Elevations of the portions of this circuit that 
lay in Oklahoma Territoiy have been included by Mr. J. H. Renshawe, 
topographer, in the report for the fiscal year 1897-98. 
From Wagoner, Indian Territory, levels were run north by Messrs. 
A. F. Hassan, C. B. Odell, and R. Coe, over the Missouri, Kansas 
and Texas Railway to Chetopah, Kansas, and from there west by 
Mr. R. Coe, over the Missouri Pacific Railway to Coffey ville, Kansas, 
making a closure of 1.009 feet on line run north from Wagoner, Indian 
Territory, by Mr. C. B. Odell over the St. Louis, Iron Mountain and 
Southern Railway to Coffey ville, Kansas. Levels were also run on the 
St. Louis and San Francisco Railroad from Sapulpa, Indian Territory, 
to its intersection with the Indian Territory -Missouri line, crossing the 
St. Louis, Iron Mountain and Southern Railway at Claremore, Indian 
Territory, and the Missouri, Kansas and Texas Railway at Vinita, 
Indian Territory; along the Kansas City, Pittsburg and Gulf Railroad, 
from the Indian Territory-Arkansas line, near Page, Indian Terri- 
tory, north to Siloam Springs, Arkansas, crossing the St. Louis and 
San Francisco Railroad near Poteau, Indian Territoiy, and St. Louis, 
Iron Mountain and Southern Railway near Sallisaw, Indian Territory. 
It will be seen from the above resume that Indian Ter itory has 
been well controlled by double-rodded lines along the various railroads, 
all so run as to form closed circuits, which have all closed quite satis- 
factorily considering the conditions of extreme heat and cold, as well 
as high winds, which existed at various times during the work. These 
lines along the railroads were used as precise levels, and all land lines 
were connected to these at the points of intersection. 
All permanent bench marks were stamped to the nearest foot.
