nearly fire-proof as possible, the proprietors having been taught to

tions. The number of acres attached is between forty and fifty, on
which there are numerous buildings, constituting a small village in
The principal manager of these extensive works is John F. Wins-
low, Esq., whose experience in the working of metals is not excelled by
any one engaged in the trade. le is also a man of genius, and the in-
ventor of several highly valuable improvements to facilitate the working
of iron. His rotary squeezers is a most effective machine, as one will
do all the shingling for forty puddling furnaces, with but a trifle of ex-
'pense for attendance, a small consumption of power, no waste of iron,
and turning out the blooms very hot it facilitates the rolling. This
preservation of the heat, coupled with the fact that the bloom is very
thoroughly upset while undergoing its rapid squeezing, is said to sensibly
improve the quality of the'iron.
The firm of Corning, Winslow & Co. is now extensively engaged in
the manufacture of puddled steel, which they commenced soon after the
art of effecting it was made known in Germany about the year 1852.
Few men in this country, if any, have devoted more attention to this
subject than Mr. Winslow. Their puddled or semi-steel is capable of
bearing a tensile strain ranging from 90,000 to 108,000 pounds to the
square inch, and is beyond a doubt equal in every respect to any made
in Europe. This material is now largely made into locomotive tires,
boiler plates, and other forms where great strength and density are re-
quired. It is further manufactured by cementation and put into spring-
steel for carriages and rail-car purposes.  Corning, Winslow & Co.
we believe are at present the only makers of semi-steel in the United
This firm give employment to about 750 persons, to whom are dis-
bursed about $18,000 per month for wages. The annual product of the
concern is about 15,000 tons, consisting of cut nails, spikes, rivets-
band, bar, rod, and scroll iron, of all sizes-with large quantities of
railroad-car axles, wagon axles, crowbars, and wrought-iron railroad
chairs. They have a capital, invested in real estate, buildings and ma-
chinery, of about a half million of dollars.
Within the year 1863 a very considerable addition was made to their
works, consisting of another mill for bar and band iron, about nine ad-
ditional puddling furnaces, machinery and buildings for making Horse
and Mule Shoes, extensive machine shops, and several dwellings for the
families of employees.
