equipped in the world, outrivaling even the establishments of Whitworth, Schneider and Krupp.
 The hammer building, says the New York Sun, is situated at the extreme eastern end of the works, and covers ground that was formerly an island and the southern channel of the Lehigh river, the river having been turned from its course to make site for the structure. It is 500 feet long, lighted by windows at the sides and q lantern in the roof, and besides the hammer contains a 6,OOO-ton hydraulic bending press and an armor-plate rolling mill & The hammer and anvil foundations are elaborate specimens of masonry. pit 5S by 62 feet large was eXcavated deep down below water level, Then heavy walls, 30 feet high, were erected on pile foundation along the northern and southern sides for the hammer frame to rest on.
 In the space between these walls is the foundation for the anvil It con sists of piles driven to bed rock, with timber frame or, top, and on that steel and iron slabs arranged in longitudinal and transverse layers. On this the an vii was built. t consists of 22 blocks of solid cast irot of an average individ- ua, weight of l7O tons, arranged one above the othjr in pyramidal shape. The topmost or.a, on which the material to be forged gill rest, is faced with steel.
 The space between the anvil, the frame supporting the hammer, was closed with cri(FbiDg, which presents a surface even Nith the floor line, the only visible porsion of the entire mass of oak and i f,n forming the anvil, which weighs l,SO0 tons, being the steel.faeed anjl block capping the pyramid. This block is wedge-shaped, being II feet long, feet wide at the bottom and at the top, and AZ feet high. The hammer and anvil founda- tions are in no way interlaced; the dan ger of the anvil foundation giving way is slight, but should it be displaced by the powerful blows, the hammer and its foundation will remain secure.
 Superimposed over this cyclopean mass of masonry and iron work is the
  ful, rising to the height of 90 feet.
 In building the frame which supports the hammer there are first two castings weighing l20 tons each which rise some- what in the form of quarter-circle on the inside, but almost perpendicular on the outside, to form an arch curving gracefully over the anvil. The two castings are known technically as housings. The longitudinal width of the hammer frame is AZ feet, and the distance from housing to housing is 22 feet on the floor line inside of the arch. The housings, whose bases are 10 feet by 8, are clamped to the foundation walls.
 Exactly in the center of the arch formed by the housings is the trip or ram, an enormous mass of metal 19H feet long, 10 feet wide and feet thick, the weight of which is almost 100 tons. 1t is composed of three single pieces, the lowest of which, a large block of iron faced with steel, is called the die. It is the die that will strike the metal being forged. The ram works in slides ar ranged along the inside of the hous- ings, the castings of the section above the housings.
 Connecting the ram with the piston inside of the cylinder is the piston rod, splendid specimen of perfectly wrought steel, 40 feet long and l6 inches in diameter. The piston has a stroke of l6H feet, which is the height that the die can be raised above the anvil. The weight of die, ram, piston rod, and piston together amounts to l25 tons The cylinder is single acting, the steam only lifts the hammer and allows it to . fall of it's own weight. It is when this mass of l25 tons is dropped from the height of !6X feet that the hammer ex- erts it's greatest power.
 The weight of the entire mass of iron and steel used in the construction of the hammer and its frame amounts to more than 500 tons.
