[J. Thomas Scharf (1886)] The principal streams running through Somers are the Croton on its eastern boundary, being, in fact, the boundary line itself; the Muscoot, whose course runs southeasterly from near the northwest corner to its mouth, where it empties into the Croton under the north shadow of Muscoot Mountain, and about two miles and a half from the southern line near Croton Lake; Plum Brook, rising in Putnam County and flowing southeast, empties into the Croton in the south central part of the town, about half a mile from Golden 'a Bridge; Mill Brook, Bowing southerly, empties into the Muscoot; and Potash Brook, thus named from the fact that early in the century a pot-ash manufactory was established thereon, near the present village of Somers, also rises in Putnam County, and flowing southeasterly, empties into Plum Brook about one-half mile from the junction of the latter with the Croton; Angle Fly, a noted trout stream, rises in the swamps of a valley west of Prim-rose Street, on the farm formerly owned by Mieajah Wright (the builder of Mount Zion Methodist Epis-copal Church), and flowing south empties into the Muscoot a mile from the mouth of the latter. Nu-• merous other small streams, fed by springs, are to be found in the town, thus making thesection eminently adapted to agricultural purposes.
