CHEMICAL ENGINEERING COURSE 261

Tanks of wood, enameled iron, and stoneware, with a capacity from 30 to 60
gallons, are provided for plating and cleaning solutions.

ELECTRIC FURNACE LABORATORY. The electric furnace room for alter-
nating current contains resistance and are furnaces for general purposes,
a vacuum furnace of the Arsen type, a Girod steel furnace having a capac-
ity of 100 pounds of metal, and a rotating brass furnace of about 100 pounds
capacity. There is available for the exclusive use of this laboratory the
power from three transformers each of 75 k. v. a. which may be had con-
tinuously.

LABORATORY FOR INDUSTRIAL Microscopy. A large, well-lighted room
on the third floor is provided specially for the instruction in industrial
microscopy. Petrographic and chemical microscopes and many useful ac-
cessories are available for the study and identification of textiles, pulp and
paper, paint, refractories, leather, etc. A separate chemical laboratory is
provided for the preparation of samples.

Forest Propucts LABORATORY. The United States Forest Products
Laboratory is operating in cooperation with the University of Wisconsin.
The work carried on in this laboratory is largely of a chemical engineering
nature dealing with the preservation of timber, manufacture of paper, util-
ization of wastes, and the like. The management of this laboratory pro-
vides that chemical engineering students may undertake investigation using
the Forest Products Laboratory equipment, so far as such use does not
interfere with their own work.
