duction ~ the metal aluminium from its
ores. Similar works exist At other places
here and abroad where power IL cheap.
This metal. which completes In price With
brass. bulk for bulk. was only obtainahle
hetor. its electric reduction NJ SIS to $50
per pound. The metal sodium is also ex-
tracted from soda. Alarge plant at Niagara
also uses the electric current for the manu-
facture Of chlorine for bleach. and caustlc
soda. both from common salt, Chlora,e
Of potassium is also made At Niagara by
electrolysis. The field Of electro-chemistry
il indeed fun Of great future possibilities.
Largo furnaces heated by electricity, a
single one OF which will consume more
than a thousand horse power. exist at
Niagara. In these furnaces il manufactured
from coke and sand. by the Acheson pro-
cess. an abrasive material called carbo-
rlndum. which il almost "a hard as dia-
mond. but quite low in cost. II il made
into slabs and into wheels for grinding
hard substances. The electric furnace
