NOTES ON SCIENCE AND INDUSTRY.

The exclusive manufacture has for some

In regard to the various processes proposed
for the recovery OF metallic iron from Stag. a
writer In London Iron remarks that. though in
very many cases the Stag as taken from the
furnace will be found to contain large amount
OF iron in metallic state. which will well
repay for any moderate outlay In its recovery.an
essential point is that all the work be as nearly
metal from the Stag really offers no difficulty.
