DESCRIPTION. The mine consists of a thick glass bottle resembling a quart milk bottle. In some models there is a booster charge of penthrite wax in the neck. There is a woo-den plug with a conical recess and a central hole located at the top of the bottle neck. The Fl.Es.Mi.Z. igniter, with detonator crimped on, fits into this hole in the booster. An aluminum cap screws onto the top of the bottle over the igniter, with the igniter striker being just below the cap. When in place the cap is waterproofed with a sealing com-pound and over this fits a rubber cap to assure complete waterproofing. (See fig. 247.)

OPERATION. Sufficient pressure on the igniter causes detonation of the mine.

EMPLOYMENT. The original German theory for the use of these mines was that they should be suspended on 6-foot lengths of wire below the surface of ice-covered rivers. The mine were placed 16 feet apart and at intervals mines were set to be ignited by electric detonation. The explosion of one mine would set up a sympathetic detonation which would explode those in the adjacent area.

The mines were later used for A/P ground mines, employing the Fl.Es.Mi.Z. igniter and adapted for use with other pressure type igniters.
