| Popis: | Since the demand for fats has increased so greatly and their price has reached such a high level it has become imperative that we make use of all the available sources of this most important material. A great deal of the *rocky waste land of Kansas and other states is covered with the common sumac (Rhus glabra). It occurred to the author to make a chemical study of the oil from the sumac seed to determine its fitness as a food or for industrial purposes, and the amount available. The berries from which this oil was obtained were gathered at Manhattan, Kan., in February, 1919. The husks were removed from the berries by rubbing gently in a mortar and sending the material through a small fanning mill. The clean, air-dried seeds were ground in a mill and the fat extracted with dry ether in a continuous extraction apparatus large enough to hold two or three pounds of the material. Two determinations gave an average of 11.71 per cent of oil in the ground seeds. Table No. I summarizes the results of the physical and chemical examination of the oil |
