508 FIRST REPORT UPON MAGNETIC WORK

10. WEBB.—G. W. Dean, U. S. C. and G. Survey, determined the elements
at this point in 1850, and also C. O. Boutelle in 1868.

Webb geodetic station was established in 1850. It is in Anne Arundel
County, about 2 1/2 miles by road east from Odenton, the junction of the
B. & P. R. R. and the Annapolis Branch of the B. & O. R. R. The land upon
which it is now located (1897) is the property of Mr. James Woodward,
President of the Hanover National Bank of New York City.

The geodetic station is on the side of a hill about one-quarter of a mile
north of the old Webb house.

The station is marked by a granite post with an underground earthen-
ware cone under it. There are also three reference stones so placed as to
form an equilateral triangle; the base of the triangle being on a line due
north and south, and the stones at the extremities of the base and the
vertex of the triangle are distant five feet from the granite post marking
the geodetic station in the middle of the base. A cross on the granite post
marks the center.

Mr. Dean's magnetic station was 685 feet south and 25 1/2 feet east of the
geodetic station.
