“Racks.—These are eight in number, and measure just under 8 feet by 8 feet by 4 feet. The capacity of each is roughly about 450 lbs., of dry sheet rubber. The racks are mounted on 6-inch iron wheels, running on rails of stock size, ’T’ iron (13⁄4 inches by 13⁄4 inches by 1⁄4 inch).
“The sheets are hung on split bamboos. To prevent these projecting over the edge of the rack and catching in the doors when the rack is moved in or out, a thin strip of wood, about 1⁄2 inch high, is nailed along the sides of the rack.

“Furnace.—This is of the type that aims at slow combustion. It consists of a cast-iron cylinder, 3 feet in diameter and 4 feet high, carried on a truck made of a sheet of boiler-plate, and mounted on small wheels, so that the whole can be moved easily out of, and into, the furnace chamber for easy cleaning and stoking.
“The furnace chamber is a pit lined with concrete, just wide enough to take the trolley, and about 12 feet long. The top of the furnace, which is almost flush with the ground-level, consists of a sheet of zinc or galvanised iron with numerous holes about 3 inches in diameter. Over these holes are strips of mosquito gauze, as flame and dust arresters (see [note] below). There are no holes in the sides or bottom of the cylinder.
