AD'IT (Lat. aditus, access, approach). A nearly horizontal passage opened for the pur pose of draining a mine. Incidentally, an adit may also serve in exploring the rock through which it passes. Filled with water, adits are often used as canals, by which the products of mines may be transported. Water raised from a depth greater than that reached by the adit is discharged through it, saving the cost of raising it still farther to the top of the shaft. An adit in Cornwall opens at the level of the sea, and extends inland about 30 miles. draining the district of Gwennap. It meets some shafts at the depth of 400 feet. The Ernst August adit in the Hartz Alountains, completed in 1864, is 13 miles long. The Joseph IL adit at Schein nitz, in Hungary, is 10 feet high, feet wide, extends 10 miles to the valley of the Gran, and is used as a canal and railway passage. The Sutro Tunnel, draining the Comstock lode in Nevada, is 4 miles long.
