Coolness in Buildings 



In the case of iron-roofed buildings with ceilings of small-fluted sheet 

 iron, Mr. C. E. Owen Smyth, Superintendent of Public Buildings, South 

 Australia, recommends that, if the building is near the sea-coast, a thick 

 layer of dry seaweed should be laid on sheets of paper on top of the 

 ceiling, i.e. between ceiling and roof. 



If the building is distant from the coast, the farmer should make 

 wood charcoal, and deposit a layer of that material, 6 inches thick, on 

 top of the ceiling. 



Either of the above will be found to be a good heat-insulator, pre- 

 venting excessive range of temperature variation inside of the building. 



Cool-Storage Eoom 



Mr. E. A. Ryland, Dairy Supervisor, Victoria, Australia, describes 

 a canvas room, a number of which have been constructed in Australia. 



A light wooden frame-work is constructed 6 feet square by 6' 6" in 

 height, with sloping hip-rafters on top to form a square roof. This frame- 

 work is covered with canvas or Hessian cloth down to 9 inches above the 

 (pine) floor. The lower 9 inches is occupied by a fly-proof perflation 

 panel of fly-netting. From the peak of the roof, a vertical ventilating 

 pipe takes off, capped by a cowl. This pipe is about 6 feet long so as 

 to induce a good draught. A framed door, covered with canvas, is 

 provided in one side of the room. 



Water is distributed over the roof and walls by perforated lead piping. 

 Surplus water is caught in rain-water guttering, which extends round the 

 walls immediately above the perflation panel, and thence is led away.
