MARYLAND GEOLOGICAL SURVEY 507

From the best evidence at hand, Captain Lee's station was identical with
the old geodetic station.

17. ROSANNE.—Rosanne geodetic station stands on Prospect Hill, about
five miles from Baltimore and one-quarter of a mile north of the old Fred-
erick road.

The station is 18 feet from the northeast corner of the old Bogue house
of 1845, 68 feet from a cedar at the southeast corner of this house, and 88.5
from a persimmon tree, midway between the lines to Finlay geodetic sta-
tion and the Washington Monument.

From the best evidence at hand, the old geodetic station was marked with
an earthenware cone sunk two feet below the surface of the ground with
reference posts close to the old station. The magnetic station was 126 feet
north of the geodetic station.

12. STABLER.—See description in previous list of stations.

11. SOPER.—Soper geodetic station is in Montgomery County about a mile
east of the boundary line between Prince George County and Montgomery
County and about 92 feet east of the old Columbia turnpike and about 1 1/2
miles from Burtonville.

It is on what is known as Soper Hill, and was marked by an earthen cone
sunk two feet below the surface of the ground with a granite post over it.
Similar granite posts, as reference marks, were placed true north, east
and south of the geodetic station and five feet distant from it.

Just north of the station, by the side, of the road, were two red oak trees
distant 110 1/2 feet from the station. Each of these trees was notched and
marked by a copper nail.

North 86° 05' west from the geodetic station, and distant 92 1/2 feet from it,
a brass screw was inserted in a white oak tree.

The magnetic station was 352 feet north and 42 feet east of the geodetic
station.

21. SUSQUEHANNA LIGHT.—The magnetic station -was near the old " Sus-
quehanna Light " in the suburbs of Havre de Grace.

From the best evidence at hand, the magnetic station was west of the
old light-house in the prolongation of the line from the Susquehanna Light
to Turkey Point Light, and quite close to the old light-house, which was
in very close proximity to the present Havre de Grace Light House.

8. TAYLOR.—Captain T. J. Lee, U. S. Engineers, Acting Assistant U. S. C.
and G. Survey, determined the elements at this point in 1845 and 1847.

Taylor is on Greenbury Point in Anne Arundel County, opposite An-
napolis.

From the best evidence at hand, Captain Lee's station was 54 feet north of
the geodetic station and 6 1/2 feet west of the line from Taylor to Linstid geo-
detic station. Taylor geodetic station was, in 1844, on a farm which was
then- the property of Captain Samuel Taylor, located between Mill Creek and
the Severn River. It was about one-quarter of a mile from Captain Tay-
lor's house on the north side of the road leading to the Severn Ferry, and
226 feet from a chestnut tree in the direction of a cut in the woods to Mar-
riott geodetic station. Three stakes, each 40 feet distant from the old
geodetic station, were driven in the ground as reference marks.
