         be observed in the care, handling,
         and laying of high-‘explosive serv-
         ice antitank mines. Except ,for the
         smoke charge contained               in the
         firing device (when used as second-
         ary fuze), this practice mine is
         inert. The mine is shipped empty
         and is to be loaded with sand in
         the field. When so loaded, its weight
         will be approximately         that of the
