Station 80— ;w Johnson Co. Lat. 38° 52'; Ion. 93° 35' . Valley of the 

 Blackwater, on the farm of Milton Swope, which is the E. \ of the N.E. \ 

 of sec. 4, tp. 47, r. 24 W. Observations in the orchard, 87 ft. S. of the gar- 

 den fence and 103 ft. W. of the orchard gate. Polaris observation and 

 morning elongation of needle. 



Station Si— Sweet Sprinr/s, Saline Co. Lat. 38° 55'; Ion. 93° 29'. Sta- 

 tion on the banks of Blackwater, near the N.W. corner of the fair-grounds. 

 A point on the fair-grounds fence distant 134 ft. bears S. 52°27'. .. E., and is 

 198 ft. S. of the N.W. corner of the grounds. The corner of the grounds 

 bears S. 109° 46'. 3 E. from the station. The meridian was determined by a 

 polaris observation, which was not fully satisfactory by reason of clouds. 

 It, however, served a good purpose as a check. A sun observation was 

 made, and two determinations for magnetic meridian were also made. 



Station 82 — Hemdon. Saline Co. Lat. 39° 00'; Ion. 93° 21'. A camp- 

 ing station. True meridian determined by a polaris observation and mag- 

 netic meridian determined from the morning elongation. The station is 

 just S. of the post-otfice, in a small yard of J. M. Riggins just N.E. of his 

 house. The distances from the W., S. and E. fences are Si ft., 189 ft. and 

 106 ft. The E. side of the yard is bounded by the Marshall road. 



Station 83 — Marshall, Saline Co., Lat. 39° 08'; Ion. 93° 17' . This sta- 

 tion is in the northern edge of the city in the street leading N. from the 

 N.E. corner of the court-house square. Measuring from a culvert which 

 passes through a high "fill," the station is 128 ft. N. and 147 ft. E. Two 

 star observations. 



Station 84 — An-otr Nock, Saioie Co. Lat. 39° 06'; Ion. 93° go . Ob- 

 servations in a deep ravine S. of town. The station was at the base of the 

 bluft", on the right bank of the water-way, 160 ft. above the crossing of the 

 Booneville road and 35 ft. above the large elm. Polaris observation. 



Station 85 — in Howard Co. On farm of Clark Bros., on sec. — , tp. 49? 

 r. 17 W. Lat. about 39° 02' ; Ion. approx. 92° 55' . Seven and a half miles 

 from Booneville. The number of the section could not be learned. The 

 place is easily found by means of the fine spring a few rods E. of the house- 

 The observations were made on the N.E. side of the road, 508 ft. S.E. of 

 the gate leading to the front door of Clark's house. A polaris observation 

 was made and the morning elongation was determined. We camped late 

 and no mark was used. 



Station 86 — Clark's Fork, Cooper Co, Lat. 38° 51'; Ion. 92° 40' . On 

 farm of W. F.' Johnston, which is the E. J of N.E. J of sec. 2, tp. 27, r. 16. 

 The observations were made near the N.W. corner of the quarter section, 

 a few feet W. of the main water-way and due E. of the spring on the ad- 

 joining farm belonging to C. C. Eldredge. A polaris observation was 

 made i an hour after elongation. 



Station 87 — Fraine Home, Cooper Co. La' 38° 48'; Ion. 92° 39'. On 

 sec. 19, tp. 47, r. 15 W. The station was on the ^mmon N.E. of the house 

 of Dr. Lacy. Measurements across the roads t the fences on the W. and 

 S. showed each to be 115 ft. distant. The road on the S. is known as the
