Sullivan, in Hancock County, is situated on the eastern
side of Taunton Bay, an extensive inlet of Frenchman's Bay. Within the limits of the town are eight islands, named
as follows: Capital A., Bean's, Drum, Preble's, Bragdon, Burnt, Black, and Seward. The area of the town is 17,500
acres. The surface is very uneven, yet the soil is generally good. Hay and potatoes are the crops chiefly sought;
but the land in general is best suited for grazing. The principal inland sheets of water are Flander's Moraney,
Long and Round Ponds. The outlets of the first two ponds, and Gordon's and Simpson's streams, afford power for
mills. Sullivan has lông been noted for the first-class coasters constructed in its ship-yards, and for its
immense deposits of granite and syenite, The granite contains beautiful veins of felsper green, is of superior
quality, splits well, may be wrought into almost any shape, and is suitable for any building. The chief industry
of the town now centres in quarrying and mining. Along the shore of Sullivan River. and nearly parallel to it,
is located the famous Sullivan lode, which is considered one of the most remarkable silver-bearing veins that has
ever been discovered. On this vein several companies are operating. "The country rock in which the vein is
found is a slaty quartzite, somewhat talcose, and in some places calcareous and, occasionally porphyritic."
Almost every ore of silver is separated in this vein, native silver, argentite, stromeyrite, pyrargyrite, stephanite,
and cerargyrite and the black sulphuret, the last predominating. There are now eleven incorporated companies owning
mines in the town, most or all of them being operated. Work has been done also in five or more unincorporated mines.
There has been completed in the vicinity a concentrating mill and smelting works for reducing silver ore.
