The combined annual capacity of these mines is, in
round figures, 7,000,000 tons of coal and 1,500,000 tons of
coke. Twenty of the Hillman mines are situated in the
Pittsburgh, Connellsville and Irwin fields, with shipping
facilities on the Pennsylvania, Baltimore and Ohio, Monongahela
 and New York Central Railroads. Seven of the
mines are provided with river tipples, permitting shipments
 by way of the Monongahela, Allegheny and Ohio
Rivers. Thus the company is able to ship by rail or water.
Shipments from its mines in Somerset County, Pennsylvania,
 and Preston County, West Virginia, are made by
the Baltimore and Ohio Railroad, east and west. The
combined coal acreage of these mines, and of the company’s
undeveloped coal tracts, is more than 85,000 acres.
The coal produced at the two Jerome mines is low in
volatile matter, averaging about 179), and can be burned
with much less unconsumed carbon than is the case with
higher volatile coal, and is widely known to the trade as
“Smokeless Coal.” It is in great demand for steam purposes,
 especially in cities having anti-smoke ordinances.
The Hillman Coal & Coke Company has about 14,000
acres of virgin coal surrounding the Jerome Mines. For
use as bunkering coal, this product meets the severe Government
 requirements in every detail. It can be stored
for long periods with absolutely no danger from spontaneous
 combustion. Hillman coal for gas-making purposes
 produces under the best practice from 10,500 to
11,000 cubic feet of gas per net ton of coal. Chemically,
there is but slight variation in the seam of the Pittsburgh
District coal, used for gas making purposes, and physically.
the coal is of firm structure and does not slack readily.
The Hillman Coal & Coke Company is one of the
largest shippers of coke in the Connellsville region, having
a total of 1,166 beehive and 798 rectangular ovens, located
at various plants, and producing annually about 1.500.000
