The Mimic bali is manufactured ont Of cold lead by

sucing them now prevails. Many thousands are made
daily by this machine, which produces balls of other
shapes aao by merely changing the dies or nOnlds IN
which they are compressed. The machine was pni-
chased from the inventor by the Government and there
