THE BLAKE "LION AND EAGLE" CRUSHER,

A patented improvement of the former "New Pattern" Blake machine.

Has much greater efficiency than the old. It requires only about half

the power to drive, and is transported at much less expense (the size

most used weighing several thousand pounds less than the unimproved

machine). It requires less than half the time in oiling and other

manipulation, and less than half the expense for repairs. Address
