NEW INTENTIONS AT THE AMERICAN

Among the inventions not yet noticed, the one
most novel in its inception and remarkable 10 its
operation is The Hydraulic Rock Dill by j. Echols
Of Columbus, Georgia. The dr-rod is provided With

practicable the employment of this drill even where
steam pump must be employed to mpei the water.
There is loss of effect in the TRANSMISSION Of poser
