The author presents excellent evidence that the effects of sun and wind are not necessarily additive in their effect on reducing the moisture content of fuels, but that wind may actually retard the rate at which forest fuel will lose moisture because of its effect in lowering the surface temperature of the fuel. Beyond that, he speculates on generalizations that may be made on forest fuel inflammability on a sunny calm day, as compared to a sunny windy day. Some may wish to challenge the practical significance on his findings or their validity under all conditions. Considerable further experimentation will be needed to tell the whole story. In any case, the subject is worthy of thought by all fire research men interested in rating fire danger.© Society of American Foresters, Bethesda, MD. Abstract reproduced by permission.
