The smouldering of beech and deal sawdusts in still air has been investisated. The dusts were fanned into small trains and the linear rate of propagation of smouldering measured. This rate was slow and was not materially affected by variations in packing density, particle size, moisture content or size of train provided that the latter is greater than a certain critical value, depending chiefly upon the particle size of the sawdust. Practical applications of these results are discussed.
