18 TRIANGULATION AND SPIRIT LEVELING [bull. 175. 
Incidentally to the connection between Wasson triangulation station 
and Oswesro the latitude of the Kansas-Indian Territory boundary line 
was determined by Mr. E. M. Douglas, in December, 1899, from 
Oswego, the value 37° 00' 04.18" being 422 feet north of the parallel 
of 37°. 
DESCRIPTIONS AND POSITIONS OF STATIONS. 
savanna, choctaw nation (Astronomic station). 
Situated on high ground about 300 yards northeast of railroad sta- 
tion at Savanna. The pier is made of brick laid in cement, with its 
base on solid rock. 
Observations for latitude and longitude were made with the Fauth 
combined transit and zenith telescope, No. 534. 
The latitude was determined by Talcott's method, and the Washing- 
ton Observatory at St. Louis was used as the initial or base station for 
the longitude determination. The observer at St. Louis was Mr. A. 
Ramel and at Savanna Mr. S. S. Gannett, the relative personal equa- 
tion of the observers being determined on two nights in April, 1895, 
preceding the longitude observations proper, the result showing that 
Ramel observed later than Gannett 0.075"d= 0.024". 
The difference of longitude was determined on five nights, the mean 
being 22' 32. 179"± 0.017". 
The resulting longitude west of Greenwich is in arc 
95° 50' 21.33" observed. 
+ 10.72 
95 50 32.05 geodetic mean. 
The mean of 37 results for latitude is 
34° 48' 46.49"±0.18" observed. 
+ 1.08 
34 49 47.57 geodetic mean. 
North base station was occupied upon one night as an azimuth sta- 
tion, the mark being placed at South base. 
SAVANNA NORTH BASE, CHOCTAW NATION. 
About three-fourths mile northeast of Savanna railroad station, 60 
feet west from and at right angles to west rail of Missouri, Kansas 
and Texas Railway track, in open country. Theodolite elevated 24 
feet. 
Station mark: A stone post 36 by 6 by 6 inches, set 30 inches in the 
ground. Center of station marked by cross cut in the rock. 
Reference stones are set to the east, west, and north. Distances 
from center of station to nearest corners of stones, E. 9.87 feet, W. 
10.06 feet, N. 9.64 feet, respectively.
