nerous rock a man may have geological
nomenclatura at his tongues end and still

Specimens brought to his notice. There
are, however, simple and ready moans
Of testing rock, which any man
Of intelligence will soon learn
to use with sufficient skill. To
ascertain the presence of gold, pulyeriza-
don and washing ont in pan, saucer, or
horn dish VIII usually be sufficient. To
detect silver and other metals it is some
times necessary to use chemicals. But in
some cases the precious metals declare their
presence in the rock 20 forcibly that my
test, other than an assay to determine their
amount per ton, would bo superduous. They
are not however, always tho richest lodes

mixed eye.
