Abstract
THE charts of the U. S. Ooast and Geodetic Survey have made Long Island Sound and the Atlantic border a means of geological instruction in many ways.The recent issne by the Smvey after new soundings, of a. chart which admits of convenient photographic reduction, has affol'ded me the opportunity to illustrate with a map;':• SOllle conclusions which I deduced from them many years since; and I now take advantage of it in order to snstain or modify the views before presented as the lIew facts lIIa.yseem to require.The Stl bjects are: first, The Condition of Long Island Sound in the Glacial period; secondly, The Origin ef the channel over the submerged Atlantic border .attributed to the flow of the Hudson River dul'ing a time of emergence.* This map is reduced one-half fl'om the Coast Survey Chart No. Sa, entitled" Approaches !o Rew York: Block [sland to Cape May; from surveys of 1878 to 1883," 'fhe omissions al'e a southern pOl'tflln of the ('hal't, the Lighthouses and the infol'mation to X a vigatol's on the llIargin.The additions are Cotidallines for tue Sound, taken ft'om a map pllbhshed by Prof. Bache, Superintendent of the Coast SIII','ey, in the fleport lor 18;.4,and inscribed as prepared by C. A. :'ichott, of the Coast t"urvey, from observations by Liellt.s.C, H. Davis.and J. R. Golds boron;.!:h , U. S. A,; additional bathYllletric lines for the Sound, and a stl'engthening of those over the A tlanlic border to make them more rC'adily appreciated; and a few soundings from the largel' charts of the Sound and of New York Harbor.The larger chal'ls of the Sound are three in number (Xos.114, 115, 116), the scale "";1;,, 0' (They will be "found to be or grl'at value in the class room for geological illustration of tidal Hnd sell-shore acti"n.)The soundings on the IIiSP show the depth at l1I!'all low tide in fathoms up to 3 fathoms, and in the shallower dotted portion in feet.
