New Marine Log.;

Patent has been granted for an Inſtrument, for taking Sounding at Seäz : of which the following is as corre& a deſcription as the nature of the ſubje& will admit:=-The äpparatus Confiſts of a founding weight, about eigliteen inches Joyg, the body of which contains a regiſter with two dials; of an Troy or braſs rod, twelve inches long, and of a tin buoy; äir-tignt, about ſx inches[quare, and four deep. To the bottom of the buoy is ſecured a pair of Ipring tongs, one end of which reſts on a hook, and the ſprivg part of the tongs is fixed, to a rotator, or revolving apparatus. The apparatus is compoled of 4a copper or other metallic tube, and four braſs or other metallic vanes. The tube muſt be air-tight, about twelve inches long, and one inch and a half diameter, with a tonical point, about feur inches in length. "The vanes are ſoldered to the tube in a ſpital diredion, ſ0'as to produce aro- tatory motion round the axis of the tube when ſent. into the water. On each yane is a regulator, whoſe office is to make a rotator perform a certain num- ber of revolutions, in a given ſpace, correſpondent with the calculations of. wheels of the regiſter. The rotators are to be adjuſted by experiment in wa- ter, to correſpond with the regiſters to the greateſt nicety, that 1s, to aſcertain the ſpace the machine will deſcend by every revolution of the rotartor. By altering the angles, and the fize of the vanes, the rotator may be made to revolve in any deſired ſpace.

By this method Soundings may be taken in very deep water, and in water of a fathom, without the trouble of heaving the veſſel to, although ſhe may be going at the rate of five miles an hour 3; for as the rotator regiſters the ditccnt of the fovnding weight, there is no occaſßon to pay reſpett to the kngth of line out; ſo that the mariner may veer out any quantity of line, which will give time tor the machine to deſcend.

The prominent objee of this apparatus is to do away or leſſen the errors ariſing from the old method of taking ſoundings; as the chief guide tor the mariner by that method, is to jadge of the perpendicular depth af the line
