"Experiments on wood fires in cubical enclosures of 1 ft, 2 ft and 3 ft dimensions having one side completely open are described. Measurements of the rate of burning, the flame height above the enclosure, and the radiation from the fire were made for different fire loads. The various amounts of fuel in each case (fire load) were obtained by varying the height of the cribs; 1 in. sticks were used throughout, the horizontal stick spacing was kept constant at 3 in. In general over the range of these experiments, little scale effect was apparent".
