Excerpt from Outline of the Geology of Long Island in Its Relations to the Public Water Supply First, the primitive or crystalline rocks (granite, gneiss, schist, These are a southward continuation of the formations of southern New York and Connecticut; and they may safely be assumed to underlie the entire area of Long Island, although actually exposed to observa tion only on the extreme northwest corner of the island. Second, the' Cretaceous formation continued northeastward from New Jersey, and consisting of clays and sands in many alternations with occasional beds of gravel, especially near the base, which have proved in New Jersey to be important water-horizons. The Creta ceous strata, which are 500 feet or more in thickness, mpe gently seaward and, so far as known, rest directly upon the crystalline rocks, although it is not improbable that in the central and eastern parts of the island Jurassic and Triassic strata intervene. Only the Lower Cretaceous appears to be represented on Long Island now, the Upper Cretaceous, which also contains several good artesian sources in New Jersey, having been, apparently, worn off from the Long Island area before and during the formation of the Tertiary strata which overlie it. This sketch of that part of the geology of Long Island having a bearing upon the public water supplies, has been prepared at the request and with the cooperation of Mr. John R. Freeman, in connection with his investigation of the water supply of Greater New York, and is published by his permission.
