DEAD-Lights, certain wooden ports which are made to fasten into the cabin windows, to prevent the waves from gushing into the ship in a high sea. As they are made exactly to fit the windows, and are strong enough to resist the waves, they are always fixed in on the approach of a storm, and the glass lights taken out, which must otherwise be shattered to pieces by the surges, and suffer great quantities of water to enter the vessel.

DEAD-Mens-Eyes, in the sea language, a kind of blocks, with many holes in them, but no sheevers, whereby the throads are fastened to the chains: the crow-feet reeve also through these holes; and, in some ships, the main-stays are set tight in them; but then they have only one hole, through which the lanyards are passed several times. See Plate CLXIX.

DEAD'S Part. See LAW Index.

DEAD Reckoning, in Navigation, the judgment or estimation which is made of the place where a ship is situated, without any observation of the heavenly bodies. It is discovered by keeping an account of the distance she has run by the log, and of her course steered by the compass; and by rectifying these data by the usual allowance for drift, lee-way, &c. according to the ship's known trim. This reckoning, however, is always to be corrected, as often as any good observation of the sun can be obtained.

DEAD-Sea, in Geography, a lake of Judea, into which the river Jordan discharges itself; being about 70 miles long and 20 broad. See ASPHALTITES. DEAD-Tops, a disease incident to young trees, and cured by cutting off the dead parts close to the next good twig or shoot, and claying them over as in grafting.

DEAD-Water, at sea, the eddy-water just astern of a ship; so called because it does not pass away so swift as the water running by her sides does. They say that a ship makes much dead-water when she has a great eddy following her stern.
