mately half the genuine wrought iron pipe today manufactured
 in the United States. In the early years bars,
sheets, etc., as well as pipe, were made. Now the entire
output of the company’s puddle mills is required in the
manufacture of Byers Pipe, couplings and nipples. Surplus
of pig iron, made primarily for supplying the company’s
puddle furnaces, is sold to the foundries within shipping distance
 of the blast furnace at Girard, Ohio.

Typical of the unvarying policy which the Byers Company
 has pursued in maintaining the highest standards of
quality, and in building into its pipe the longest possible
life, it is noteworthy that its rolled products have always
been made of unadulterated wrought iron with no admixture
of scrap of any nature whatsoever. In this connection it is
interesting to examine the picture of the old puddle mill,
shown on the opposite page. It stands on the site of the
original Byers plant, and the sheets which form the siding
and roofing were made in Byers own works in 1881. Without
 paint, without galvanizing, and practically without repairs,
 these wrought iron sheets have served for 45 years in
the smoke and sulphur laden atmosphere of the industrial
plants and railroad yards of Pittsburgh’s South Side. Their
condition today makes it appear that these old sheets will
last for another generation. Many records of old Byers
Pipe in buildings that have been dismantled also show uninterrupted
 service for forty, fifty and more years—all bespeaking
 the exceptional life of old-fashioned wrought iron.

While higher in first cost than modern steel pipe, the
lasting qualities of Byers Genuine Wrought Iron Pipe make
it particularly adapted for permanent installation where
ultimate cost per year of service is the dominant consideration.
 It finds its chief uses in the plumbing, heating and
other pipe systems of large buildings; in railway service,
particularly for locomotive piping and for airbrake lines;
in the oil and gas fields, both in the wells and long distance
pipe lines; for water and gas service lines, and other underground
 installations; in industrial plants for handling process
liquids, hot water, steam returns and in other similar services
where corrosion is a factor to be reckoned with.
