522 TRANS. ST. LOUIS ACAD. SCIENCE. 



Station \i%— Stickler ville, Sullivan Co. Lat. 40° 09' ; Ion. 92° 58'. 

 Near the S.W. corner of the N. W. qr. of sec. 22, tp. 62, r. 18 W. The N. 

 W. corner of the church bears S. 31° 15' W., and is distant 731 ft. The 

 same corner of the church is 137 ft. S.E. of the qr. sec. corner before men- 

 tioned. Polaris obs. not at elongation. 



Station i^g — Kirksville, Adair Co. Lat. 40° 12' ; Ion. 92° 37'. In 

 a vacant lot, owned bj Dr. Hurley, on the S.W. corner of Fifth and Fill- 

 more sts., 76 ft. from the centre of the latter and 83 ft. from the centre of 

 the former street. The left side of the tower of the State Normal school 

 building bears S. 69° 02'. 5 E. Polaris obs. on elongation. 



Station 140— Z,a Plata, Macon Co. Lat. 40° 00' ; Ion. 92° 34' . Sta- 

 tion in the street about midway between the track and the N. fence. The 

 middle, E. and W. line of sec. 7, tp. 60, r, 14 W., is 486 ft. N., and the E. 

 line of the section is 637 ft. E. These distances were measured along the 

 streets. The house of B. F. Bragg is on the S. side of the street, a little E. 

 of the station. Polaris obs. on elongation. 



Station 141 — /« Macon Co. Lat. 39° 53' ; Ion. 92° 22'. Station on 

 Bear creek bottom, 304 ft. N. and 832 ft. E. of the middle of the S. line of 

 sec. 23, tp. 59, r. 13 W., near Harris's farm. Some error was made in 

 reading the verniers in the star observation. It is conjectured that the 

 altitude was read too high by 10' . This conjecture is baesd on observa- 

 tions at the next station, made at elongation and an equal interval after 

 elongation, allowance being made for the change in latitude. 



In the magnetic determination on the morning of the 12th marked dis- 

 turbances of the needle were observed. The declination diminished, 9' 

 between 6 and 7 o'clock. 



Station 142— /« Shelby Co., 3 miles S. of Shelbyville. Lat. 39° 44' ; 

 Ion. 92° 04' . The middle stone on the N. line of sec. 5, tp. 57, r. 10 W., 

 bears N. 4°, 50' E., and is distant 910 ft. Polaris obs. on elongation. 



Station 143 — In Mottroe Co., on the farm of Henry Winkler, 40 ft. E. 

 of the centre of the road, and 669 ft. N. of the S. line of sec. 35, tp. 56, r. 

 10 W. The road, which runs N. and S., divides the S.W. qr. of the sec- 

 tion in halves. Polaris obs. on elongation. 



Station 144— /« Monroe Co. Lat. 39° 22' ; Ion. 91° 59'. On the 

 summit of the S. bluff of Long Branch of Salt river, W. of the road, on 

 land of B. F. Dowell. The land is in sec. 30, tp. 53, r. 9 W. The station 

 was about 75 ft. W. of the road, which is on the E. line of the section. 

 The Baptist church across the road is about 50 ft. farther S. than the sta- 

 tion. These measurements were forgotten, and the distances were esti- 

 mated the same day after having left the locality. Polaris observation on 

 elongation. 



Station m^z^ — Montgomery City. Lat. 39° 00' ; Ion. 91° 30' . The sta- 

 tion is 105 ft. W. of the middle (N. and S.) line of the S.E. qr. of sec. 32, 

 tp. 49, r. 5 W., and a perpendicular laid off to the track of the Wabash-
