A partial chemical analysis was performed on representaive samples of balsam fir, white fir, white pine, and white spruce. The results as percent of dry matter ranged approximately as follows: ash 3-5; total nitrogen 2-5, most of which was in the form of protein: soluble sugars 2-4; xylan 3-5; lignin 11-18; ether extract 35-46. After some purification the ether extract yielded acid values of 4-25, saponification numbers 132-167, densities 0.925-0.954 and refractive indices of 1.473-1.480.
