Blasting Rocks By Galvanism

- Aod of blastiner rocks by Galvanism has been invented by Mr. Roberts, of Scotland. The Glasgow Courier chives an account of an entirely successful experiment of this kind, perfomed at the Western Graigs Quarry. At the close of the deacription of this experiment, the writer says. - " The whole face of the rock was ris-en from top lo bottom, and from thrce o four tons of stone wcro torn from the hiH, and came thundering down like an nvalacnhe. It is iinpossible to imagine anything more grand or interesting tlnn this triumph of science ns applicd to practical utiliiy in rendering a hitherto most dangerous proCC&8 perfectly safe and simple in itsoxecution.'"
