total amount of high explosive contained in the shells of smaller calibers must not<br />
exceed the quantity of explosive in one 9.2-inch H. E. shell for one hole. (2)<br />
Between each shell of the smaller calibers there must be a space of at least two<br />
inches in order to allow the water to circulate. (3) The limits for each hole are<br />
as follows: One 9-2-inch, three 6-inch, five 6O-pdrs., or seven 4.5.inch; place over<br />
the mouth of the shell a piece of sheet iron with a hole cut in the center to fit<br />
closely over the nose of the shell in such a manner that it will stop the overflow of<br />
sludge during the burning. The composition of the sludge, if possible, should be<br />
80 parts of TNT or Amatol sludge and 20 parts of Ground Flare composition<br />
(by weight). If this is not available, ordinary dry TNT or Amatol sludge can be<br />

used, but there must be no lumps in the sludge. The capacity of sludge to be used<br />
for one 9-2-inch shell will be approximately one pound. k. Place the sludge on<br />
the sheet iron around the nose of shell and also inside the piug hole of tJ:te shell<br />
on the surface of the H. E. On top of the sludge place a quantity of smokeless<br />
powder or cordite. This will he ignited as follows: An electric fuze is first put<br />
into a smaIl shalloon bag of black powder I~~ oz., fixed to the brass cap of thsi<br />
fuze by means of a piece of string. This bag should be tied in the center of a<br />
small bundle of cordite (aooye and below the brass cap). It is necessary to have<br />
the sticks of cordite all touching around the bag of black powder and electric<br />
fuze. After this the fuze should be joined to a cable connected to an electric<br />
exploder (see Fig. 41. L The burning must be carried on only when the water in<br />
the tank is cold. m. After burning is completed the shell must be removed from<br />
the htJle and washed to remO\-e an)- carbon. and must be then inspected by means<br />
of aD. electric lamp. n. ~o one is permitted on the burning ground while the
