R. R., assisted by Mr. F. E. Schall, shown in Figs. 163 and 164, is a well-designed frame ice-house, 63ft. X 32 ft. 8 in., out to out, and 32’ft. high from bottom of sill to top of plate. The house is dividedinto two compartments, each 30 ft. X 30 ft. inside. The distinguishing feature of this design is thecombined use ot an air-space and a space filled with sawdust in the side walls, thus forming a doubleprotection against the penetration of heat. A ventilator at the ridge of the roof, 8 ft. wide and 4 ft.high, extends nearly the entire length of the building, affording excellent ventilation. There arefive double doors over each other on both outside walls of each compartment, and six such doorsover each other in each gable end. These double doors, one outside and the other inside, are madeto close tightly, leaving an air-space of 6 in. between them. The inner doors are made in twopieces, so-called Dutch or halved doors, to facilitate opening inwardly as the level of the ice ischanged. The building rests on small masonry walls, and the floor consists of i-in. rough hemlockboards laid open on a layer of coal dirt. A number of drain-holes, 6 in. square, are provided in thefoundation-walls to allow drainage.
The principal timbers used are as follows: sills, 4 in, X 10 in., laid on top of the stone walls;inside studding, footing on the masonry on the inside of the sill, 2 in. X 4 in., spaced about 20 in.;inside corner-studs and door-studs, 3 in. X 4 in. The inside studding is planked on both sides withi-in. rough hemlock boards, and the space of 4 in. thus formed between the boards is filled with saw-dust. Outside of this inside studding, which is double sheathed, forming a space filled with sawdust,as explained, there are additional outside studs, 3-in. X 10-in. hemlock, planed on two sides, footedon the sill of the building. These outside studs are spaced 3 ft. 4 in. all around the outside of thebuilding, excepting at the doors, where 4-in. X 9-in. special door-studs are set flush with the insidesheathing of the house. Hemlock nailing-strips, 4 in. X 1 in., are fastened on each side of the 3-in.X 10-in. outside studs, next to the outside sheathing of the inner sawdust space. These nailing-strips serve to support f-in. tongued and grooved white-pine boards, planed on one side, which arefitted horizontally between the outside studs, thus forming a 4-in. air-space outside of the 4-in. saw-dust space. The transverse partition at the centre of the house between the two compartments isformed of 2-in. X 6-in. studs, sheathed on both sides with i-in. rough hemlock boards, the 6-in.space thus formed being filled with sawdust. Several doors are cut in this partition to afford con-nection between the two compartments. The plates of the side walls are 4-in. X 10-in. hemlock;rafters, 3 in. X 8 in., spaced 24 in.; tie-beams or ceiling-joists, 3 in. X 10 in., spaced 4 ft., and
