 New Chart Made by Ex-Superint endent
 EIendenhaH and Takes in the Whole oi
 New Haven HarbOr, Includes Fair Ha.
 ven, WestviIle and Part of Several Towns.
 Captain Charles II. Townshend has in his possession an advance sheet of 1 the new coast survey chart of New Haven harbor and it's approaches, bear ing date April 30, 1895, which shows interesting data when compared with l the old Hassler chart which was con l structed from a survey made by the United States government between the years 1840 and 1S45. The new chart Is very valuable production, as 1t is an exhibit of the best hydrographical and typographical work known to chart makers of the present date. The chart is drawn on a scale of one-twenty thousandth and was made under the direction of ex-Superintend- ent T. c. Mendenhall, ILL. D., super intendent of the United States coast and geodetic survey, and completed by the present superintendent, General w. w. Duffield. Verefied by Andrew Braid, assistant in charge of office, and Lieutenant Commander Jeff F. Moses, U. s. N. inspector of hydrography. This new chart takes in the whole of New Haven harbor from the extreme northern limits of the town of New Haven, including also the city the l borough of Fair Haven, the village Of Westville and parts of the towns of Milford, Orange, Woodbridge, Hamden, North Haven and the annexed districts, "Raynham" and Morris Cove" eX- tending the hydrographical section Into Long Island Sound, as far as the state line, between New York and Connecti-- cut.
 On this chart seaward the soundings have been made with the greatest care the depth and quality of the bottom carefully noted with every rock, light house, buoy and landing located by triangulation and the best methods known to surveyors of this date.
 The breakwaters so far as construct ed are clearly shown; and the good work done by the United States engineers in way of harbor of refuge and deepening the channel is clearly shown-when the new chart is compared with the old one of 1S40.
 T UT ulSld1lCG IIlG CIldIlIlGl ONtI 0'lo ohlS 5 Bar in the chart of 1840 shows one- eighth of a mile wide and seven feet depth at mean low water. On the chart of 1895 one-quarter of mile wide and seventeen feet deep at mean low water and in the channel near Southwest Ledge lighthouse the old chart gives twenty-two feet at mean low water, while the new chart shows clearly twenty-five feet, twenty-seven feet and one mile south thirty feet, where 1t rapidly deepens to fifty feet at low water and allowing for mean rise of the tidal wave seven feet give New Haven harbor depth which with little dredg- ing will accommodate the deepest draft vessels of the world, whether iron clad battleships or merchant steamers The former, of course, would anchor in the new roadstead back of the west break water off Savin Rock, which shows in one place thirty feet of good holding ground, with an area of several square miles.
 The topography Is beautifully exc cuted. Every town, highway, city, borough, village, street, edff1ue or build ings all exactly located, the farm land with fences, ditches and monuments all in exact position and anyone now wishing to get a knowledge of outlying lands or city lots can use this chart to very great advantage.
 This chart shows the latitude of Long Wharf lighthouse, 41-17-34N; longitude, 72-54-56W.

 The plane of reference is mean low water.

 Average height of high water above the plane of reference, six feet.
 All elevations are referred to high water and are expressed in feet and by contour lines, showing successive of twenty feet.
 With the foregoing abridged outline of this chart we may make mention of the fact that this splendid and use ful production is the result of an effort made by the harbor commissioners, supported by the chamber of commerce and the city government, ending work that New Haveners may be justly proud of.
