NIPHER 4^^^ ANN. KEP. MAGNETIC SURVEY OF xMISSOURl. 455 



Station ^S— Union, Franklin Co. Lat. 38° 25'; Ion. 90° 59'. Obser- 

 vations in the lane leading to the house of 



(opposite the house of John Crow), estimated to be about midway between 

 the barn and the road. The court-house bears S. 26° 01. j E. and is about 

 5 of a mile distant. Polaris observation. 



Station ^() — Roedersville, Franklin Co. Lat. 38° 24'; Ion. 91° 10'. 

 Sec. 36, tp. 43, r. 3 W. df 5th prin. meridian. The observations were made 

 a little S. of E. from the house of J. F. Roeder, distant about 300 ft.* from 

 Roeder's E. line, beneath two large oaks located on land owned by C. 

 Henneke. These trees are 20 ft. from the main road fence. 



On the night of the 9th the watch stopped. Before leaving St. Louis 

 its rate had been reduced to less than half a second per day, but the intense 

 heat of the 7th and 8th had affected the oil of its bearings. The watch had 

 not been cleaned for two years. Returning to Washington the watch was 

 sent to St. Louis to be cleaned. It was only roughly rated after cleaning, 

 and was used for the rest of the summer without further regulation. Its 

 rate was determined at the close of the summer as will be hereafter shown. 

 Station 60— Washington, Franklin Co. Lat. 38° 31'; Ion. 90° 59'. 

 Observations in the pasture field of Dr. E. McLean, near an oak tree stand- 

 ing alone in the field. The station of 1S79 '" ^r. McLean's yard is about 

 1500 ft. N.E. and on the opposite side of the bluff. Two complete declina- 

 tion determinations were made, the second of which, however, was not fully 

 satisfactory, as the telescope was displaced during the interval between the 

 morning and afternoon observations. The silk fibre was also broken dur- 

 ing the afternoon observations, which introduced a srhall error due to the 

 torsion of the new fibre, the effect being increased by a rain. The two 

 determinations differed 5'. The observations confirmed the work of 

 1879, which was very important. A polaris observation was made for me- 

 ridian. 



Station 61— in Franklin Co. Lat. 38° 24'; Ion. 91° 16'. On sec. 31, 

 tp. 43, r. 3 W., in the orchard of Julius Wulfert, 164 feet W. of his house 

 and 72 ft. from the road fence. Polaris observation and morning elonga- 

 tion of the needle. 



Station 62— Cafman, in Gasconade Co. Lat. 38° 19'; Ion. 91° 32'. 

 Sec. II, tp. 41, r. 6 W. Farm of Wm. J. Allen, in the field about 60 rods 

 N. of the house, near a small elm tree. An oak tree on the roadside a little 

 S. of E. bears S. 82° 51.3 E. ; this tree is on the line of the " Kirkwood 

 survey." Polaris observation. 



Station 63— /« Gasconade Co. Lat. 38° 17' ; Ion. 91° 3.S'. At the cross- 

 ing of the Dry Fork of Burbeuse river, about 5 miles from station 62, on 

 the Washington and Springfield road. The observations were made at 

 the edge of the road at a point estimated to be about two or three hundred 

 yards beyond the crossing of the stream. The measurements and sketches 



* In all cases where distances are given as approximate, they were measured in paces of 

 29 inches; in other cases they were measured by a so-ft. tape line. In a few cases for long 

 distances the distance was estimated, and it is so stated.
