Getting Oil From Needles.

Investigations of the yield and tha value of cedar oil obtainable from some of our southern and western trees have been made by the forest service partly; with a view to the possible utilization of waste material left after lumbering in the national forests. In these investigations, longleaf and western yellow pine leaves produce the most promising results, but the needle oils obtained from these pines did not surpass the already firmly established spruce and hemlock oils. The large quantities of needles anff twigs on forest service timber sale areas are not only a sheer waste, but also form a special fire hazard. An increased market for leaf oil would make possible the utilization of some of this waste niaterial.
