J O 2 gee THE MARINE RECORD. 7 WORK ON CONNEAUT HARBOR. The accompanying diagram gives a fair idea of the plans of Jared A. Smith, Col., corps of engineers, U. S. A,, for the improvement of the harbor at Conneaut, O., which, . when completed, will make that port one of the safest on Lake Erie. . Capt. Q. Gilmore, inspector of construction, has already started on the preliminary work. Men are engaged cutting about 300 cords of brush for mattrass Mouth of Channel, 350 ft.

These cribs will be sunk in four to five fathoms and the construction will be carefully carried on throughout. 4 TO OOlVlIN RECENT MARINE PATENTS. 576,169. Screw-Propeller. Philip D. Stead, Pelhamville, N.Y. Claim.—A screw-propeller having two diametrically- opposed blades, consisting of a relatively flat part at the rear, in a longitudinal plane of the axis, from which flat part the opposite blades extend forward helically along the axis, the pitch and diameter.of the blades gradually in- creasing from their rear ends. 579,548. Device for Locating Sunken Boats. Albert H. Pierce, Hillsdale, Mich. Claim.—In an apparatus for locating or recovering sunk- en boats, the combination of the shouldered cone-shaped eye C having an orifice through it, said cone-shaped eye being fastened to the boat, the rope B, passed up through said orifice, a signal attached to said rope and adapted to rise to or above the surface of the surface of the water, a grappling-clamp F having two pivotally-connected jaws each having a heavy flange on the inside of its base, said clamp being adapted to be run down on the rope and en- gage the shoulder of the cone-shaped eye, the ring G also being adapted to be run down on the ropes B and H and onto the grappling-clamp to hold the jaws of the clamp firmly in place, and the cable H attached to the ring at the top of the grappling-clamp. 578,562. Marine Drag. Nie Claim.—A marine drag having an open mouth and flex- ible walls of canvas capable of being distended by the pressure of the water when put overboard, an oil-chamber constituting a permanent part of the drag formed within the interior thereof and having a flexible wall against William H. Hart, Brooklyn, which the pressure of the water acting within the drag is exerted to expel the oil from the oil-chamber. A drag tapering from the mouth to the rear end and having a Port Arthur, Galveston and New Orleans, in the effort to reach the Gulf of Mexico and the ocean trade beyond. The alarm has been sounded that this connection would injure the lake trade and especially the city of Buffalo by turning a vast amount of traffic to the new short cut to the Atlantic Coast. — - yee The new, line, the Kansas City, Pittsburg & Gulf rail- way, has just been completed to Shreveport, La., 560 miles south of Kansas City. The connections beyond Shreve- port will be closed about the rst of May, when freight and passenger trains will run through between Kansas City and Port Arthur on the gulf. It is expected to run freight trains between Kansas City and Shreveport in forty-eight hours. It now takes from five to seven days to transport freight there, unless special service is given. Arrange- ments will also be made to quote through rates from Kan- sas City to all parts of Europe, South America and Mex- ico. Now let us examine the distances, The Kansas City, Pittsburg & Gulf Railroad, when completed, will be the shortest route from Kansas City to the Gulf by over 100 miles, which will enable this road to make even lower rates than are now made by the lines from the Missouri river to either New Orleans or Galveston. The distance by the new road from Kansas City to Port Arthur will be 767 miles. From Kansas City to New Orleans it is 878 miles, and from Kansas City to New York 1,303 miles.

Ship’s Steering Apparatus. Charles H. Rich- ardson, Gloucester, Mass. Claim.—The herein-described steering apparatus consist- ing of a wheel-shaft B universally jointed or pivoted at its rear end and having a screw-threaded portion B engaging a nut E pivotally connected to the rudder-post and a roller H journaled on said shaft and adapted to be supported on a stationary rail or plate. A SOUTHERN OUTLET TO THE COAST. In the Record of February 25, we referred to the short cut from the Missouri valley and the great Southwest to “Fresh danger threatens the lines between the Missouri River and New York. Active as the Gulf competition has been during the past two years, it will become still more energetic within a few weeks. The Kansas City, Pitts- burg & Gulf Railroad expects to open its entire line from Kansas City through to Port Arthur, Tex. (Sabine Pass), about May 1. “Port Arthur is destined to become a more important port on the Gulf of Mexico than either New Orleans or Galveston. It enjoys many advantages not possessed by the other Gulf ports. It has the advantage of a deep water harbor that will accommodate the largest ocean steam- ships. From soundings taken the least depth in the dredged channel of Sabine Pass was 24.1 feet at mean low water. The depths ranged from 24.1 to 28.7 feet . Addi- tional appropriations have been made by congress, and more are expected in the future, which will bring the depth of this channel to 26 feet or more.” $$$ There is not in the April number of Cassier’s Magazine an uninteresting topic. The writers on these topics are all experts and specialists in their various lines, and the sub- jects treated are electric traction in city streets, ship- building in Great Britain, the metric system from a me- chanical point of view, an artificial ice skating rink, steam engines for modern power houses, a ten-ton pneumatic traveling crane, commerce on the great lakes, the ideal engine lathe, modern methods of electric energy trans- mission and current topics.
