So that unless the drops can be made to

Cy. 1t was found that arsenic was the
very thing. SO now small quantity of
arsenic is mixed with all the lead and

as they leave the colander and most of
them harden in that shape. Some are
imperfect, however.

But the good ones are not finished vet.
They are next put into kcg-likc cylin-

the way this rlumbago comes all the
way from the island OF Ccvlon on pur-
pose-the cylinder is set to revolving

out beautifully polished and all ready
to be screened. The screening is To sep

for several different sizes are made, rang

ball no larger than "A cabbage seed, and
of which it must take several to do much

They are now ready TO put up for mar

part of the whole. Little bags. large
enough to hold twenty-five pounds, are
hung just below some long iron tubes
through which the shot runs and falls
into the bags, and when just twenty five
pounds have run in Il valve closes, and
not another grain can get through. so

they are piled into heap and are
