down six inches by a single blow. In fact, it is said, that on full
stroke, the blow of this hammer is equal to the fall of one hundred and
thirty-five tons. They have also another hammer on the same princi-
ple of seven tons weight, and seven feet nine inch stroke, and one of
six tons, and six feet stroke, and two of the Patent Willard Helve
Hammer, each of two thousand pounds weight, for smaller work, and
another of the same pattern of fifteen hundred pounds.  They haveW
nine furnaces or gangs expressly for making forgings, and a crane cayp-
ble of handling seventy-five tons, by which a shaft forty feet long and
eighteen inches in diameter may be placed beneath the hammer and
swung from the anvil to the furnace with the utmost facility. At these
works were forged the anchors of the old " Constitution," the shafts
and other wrought iron work, amounting to some two hundred and
fifty thousand pounds, for the new " Constitution," the large forgings
for the Iroquois, Narragansett, Pawnee, Kearsarge, Ossipee, Sacra-
mento, Juniata, Adirondac, Canandaigua, Sagamore, Cayuga, Ka-
nawba, Unadilla, Ottawa, Seneca, Pembina, Kennebec, Owasgo,
Aroostook, Tahoma, Pinola, Sebago, Lenora, Conewaugh, Maratanza,
Tioga, Octarora, Port Royal, Paul Jones, Mississippi and Merrimac,
the wrought-iron work for the Golden City, Colorado,. Arizona, Henry
Chauncey, Montana, Great Republic, China, Japan, Alaska and
America,-in fact, every Steamer comprising the new fleet of the
Pacific Mail Steamship Company, running on both Atlantic and Pacific
Oceans, and acknowledged to be the largest and finest ships in the
world. The shafts, alone, for some of them, weigh over forty tons in
the Forging, and are twenty-four and a half inches diameter, by thirty-
nine feet, seven inches, in length. They have also completed the famous
Truss work for the Iron-clad Frigates now building by Government at
their Navy Yards; and are now finishing the Wrought-iron work for
the four Wooden Frigates for the Navy, known as the Geared-engine
Ships, and, undoubtedly, to be the fastest in the world. The Forgings
for the original " Monitor " were made here, and the greater part of all
those for the Iron-clad Navy of the United States, and including those
for the Italian Iron-clad Frigate " Re di Italia." In fact, the largest
forgings ever made in America have been produced at these works.
Less imposing than the forge with its great hammers, but scarcely
less important, is the scrap heap from which the material is selected
for the various articles manufactured. The yards and buildings devoted
to the scrap, present a most remarkable sight; there is hardly a branch
of the iron and steel manufacture that is not represented in the
scrap heap; boilers, wheels, axles, tires, engines, knives, forks, button
plates, turnings and planings from the machine shop, and even dis-
