 94° 37'- 7- Bluff" between Grand avenue and McGee street and N. of Pres- 

 byterian church. 



Station 16— Sedalia, Petiis Co., Mo. Lat. 38° 42^.2 ; Lon. 93° 15'. 5, 

 In public square, W. side. Set by happy accident exactly in axis of an 

 accurately mounted transit which was 40 yds. S. This transit was mounted 

 on a section of gas-main about 6 inches in diameter, which has possibly 

 influenced our results slightly. 



Station 17 — Vinita, Indian Territory. Lat. 36° 4I^4•, Lon. 95° 07'.!. 

 Complete determinations were made in the A formed by the crossing of 

 the Missouri, Kansas and Texas and the St. Louis and San Francisco 

 railroads. From lack of transportation it was impossible to secure abetter 

 location. The distance to each track was 60 yds. 



Fearing local action, magnet Cg was oscillated 60 yds. on the opposite 

 side of the 2^ track, but with no protecting tent. The wind interfered to 

 some extent, but the sky was cloudy, preventing insolation.
