[Illustration: SIDE VIEW OF PRECEDING PHOTOGRAPH, SHOWING EXTERNAL ARRANGEMENT FOR STOKING FURNACES. Federated Engineering Co., Ltd., Kuala Lumpur.] DETAILED DESCRIPTION.--As enquiries are often received it is permissible to reproduce the following detailed description of the original house. This appeared in the Fourth Local Report (Malaya) 1916, issued to subscribers by the Rubber Growers' Association. "The house has a steel frame-work, 22 feet long, 16 feet wide, and 22 feet high. Of the length, 14 feet is occupied by the platforms, and 8 feet by the chambers. These measurements can be varied. The whole of the width (16 feet) is occupied by compartments of which one series is placed above the other. [Illustration: FRONT VIEW OF DOUBLE "DEVON" TYPE OF SMOKE-HOUSE. Glenmarie Estate: Batu Tiga Co.] "_Platforms._--The loading verandahs or platforms are of ordinary 'seriah' timber. "_Compartments and Furnace Chamber._--These are enclosed with Bell's 'Poilite' sheets, each of which measures 8 feet by 4 feet by 3/16 inch. The sheets are affixed to the steel stanchions, doors, etc., by galvanised bolts (1 inch by 1/4 inch) which pass through iron flats measuring 8 feet by 2 inches by 3/8 inch (about). These iron flats hold the sheets at the edges. The dimensions of the compartments are 8 feet by 8 feet by 4 feet. "_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 (1-3/4 inches by 1-3/4 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.

Shows door to furnace chamber, and ventilator.] "_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.
