BrssrNFE STEEL ESTABLISHMENTS IN THE UNITED
SrArEs-Mr. Alex. L. HALEY, whose name IS init
mately identified with the growth of the Bessemer
Works of this country, announces the following
facts IN connection with the working condition of
our Bessemer Steel establishments. The product of
American Bes>emer Works has been steadily in
ere.s>ing from various CauSes-better organization
better refractory materials. and chiefly numerous
large and small improvements IN mechanical details
In 1875 an output of 500 tons of ngots per month
was barely reached in the best works IN 1870 the
production AT Troy and Harrisburg had risen
10 about loo tons per month maximum.
Early in 1872 the Harrisburg works turned
out above 1900 tons per month, AMI
for year OF more these and the Cambria Works
took the lead in this direction, the latter having
run as high as GO tons in one week. During
1878 the Cambria, Harrisburg, North Chicago, aud
Joliet Works averaged p 10 80 heats of five tons
each per "a hours During the week ending July 12,
1873 the Harrisburg Works made $50 heats yielding
$40 tons of iDgOtS The product OF the Cambria
Works for the week ending Jan. Il, 1874, was ls'
heats. giving qjG tons of ingOtS. Daring - hours
FRIDAY Jan l6I a. blows were made On Friday,
Feb 49, 1874 the Troy Works made 20 heats in "A
hours yielding 20 tons of ingos. This Is the most
remarkable run on record. During the week ending
April the Troy Works made l95 heats yielding va
tons'of ngots which Is the largest week WORK. IN
January. 1874. the Troy Works made 2.St9 tons OF
ingots aud in April, the North Chicago works made
3.536 tons, which is the largest month work These
are all hve-ton plants, consisting of two hve-ton
vessels and accessories and they work only eleven
turns or five and half days per week.
