DescriptionThe moisture content of the top layer of coniferous needles and twigs covering the forest floor is one of the factors of forest fire danger which must he determined accurately if fire danger in such timber types is to he measured. As this moisture content cannot he estimated accurately and as a difference of a few per cent of moisture, especially in the lower range, has been found to cause significantly different inflammability, measurements rather than estimates are needed.
