498 FIRST REPORT UPON MAGNETIC WORK

DESCRIPTIONS OF MAGNETIC STATIONS IN
MARYLAND.

STATIONS OCCUPIED BY THE MARYLAND GEOLOGICAL SURVEY IN 1896.

The arrangement of the stations is alphabetical. The number
indicates the general order in which the stations were occupied, and at
the same time serves as a brief method of designating the various
stations. When an additional station was obtaine'd in the same town
or locality a capital letter is attached to the number.

All the stations were temporarily marked at the time of observation
by wooden stubs with brass nails or screws in their tops. These stubs
were left in the ground. No money was available for marking the
stations more permanently, nor was it particularly advisable, except
in a few cases, to spend any great amount of time or money in this
way. The descriptions below will, in general, suffice for future obser-
vations at the identical station.

30. ANNAPOLIS, ANNE ARUNDEL COUNTY.—On the Naval Academy grounds,
in the open area near the Observatory; 45 paces west-northwest of Observa-
tory and 62 paces northeast of Herndon Monument. Site was chosen by
Professor Terry, in charge of the Physical Department of the Academy.

32. BALTIMORE, FORT MCHENRY.—The description furnished by the Coast
and Geodetic Survey of their station occupied in 1895 by J. B. Baylor,
Assistant, is as follows: New station selected is in the large open space
in the extreme eastern part of the fort next to the outer sea-wall; 16 1/2 yards
from the outer sea-wall and 13 yards from a locust tree, and is marked by
a substantial locust post with a copper tack in it, and sunk flush with
ground. Site is quite free of artificial disturbing influences, such as pipes,
ordnance materials, etc.

The Geological Survey station was placed as near as possible to above
station. The locust post could not be found, but with the aid of the orderly
who had assisted Mr. Baylor, it was possible to locate within a few feet of
Mr. Baylor's station.

[The former C. and G. S. station of 1877 and 1885 in another part of the
grounds had to be abandoned on account of proximity of electric cars. The
commander of the Fort states that there is a bed of iron below the grounds
of the Fort.]

29. BEL AIR, HARFORD COUNTY.—In the garden back of Rouse House, a
hotel; 110 paces back of the house, 41 paces north of south barbed-wire
