cipal abrasivcs fall into three genera
groups: Those which occur ~ rock for.
nations, aud are cut and manufactured
directly into the form desired, while re-
tanning their original rock structure and
appearance, ~ grindstoncs, whetstones,
etc. those which occur ~ u constitucn,

corundun, emery and garnet: artificial
abrasives, as carborundun, crushed
steel and artificial corundum.
The use oi abrasivcs il growing with
the increase of our manufacturing indus
tries. The total value of natural abras-
ives produced in the United States in
1901 was $l,l0l,b72, NJ compared with
81 ,oOS ,O73 for 1900.

GRi>psroNns.
The production nf grind-tonrs in Il Q
United States is almost entirely from
Ohio and Michigan. The principal
grinds,onc dis,ric, in Ohio is included IN
I.orain, Cuyahora and summit counties,
with Cleveland as u center, the largest
vrindstonc uuarrics aud manufacturing
plants being within twenty-five miles oi
Cleveland, The Quarries in southern
Ohio are along the Ohio river, west of
Marietta, and inland northwest of that
city. 4 few quarries are in West Nir-
ginia, across the river from Marietta.
The Michigan luarries are ON the shores
Of Lake Huron, about ninety miles north
Of Port Huron, near Grindstone City. In
South Dakota are located the Iuarries Of
the Edgcnont Stone company, near
Edgemont, on the line Of the Burlington
and Missouri River railway.
