GET OIL FROM
 SEED OF GRAPES
Chemist Finds Use for Re fuse Once Thrown Away
 As Valueless.

From the grape. the source of wine now under a ban extra dry, is being derived a new food oil, pressed from the seeds which formerly were dis carded. This recently discovered by product has been tested by scientists who say that it is edible and nutri- tious and may become rival of olive and cottonseed oils for cooking and for salad dressing.
 The news brought some comfort to vineyard owners of California, Ohio and this state, as the preparation of the oil on a large scale may Increase the profits from grape juice. Even after the oil has been pressed out the residue of the seeds is found to be of value as a feed for animals.
 Dr. J. H. Shrader, who is connect ed with the bureau of plant industry, of the U. S. Department of Agricul- ture, has made extensive investiga- tions in the commercial utilization of grape seed. In paper read before the division of industrial chemists and chemical engineers, of the Amer ican Chemical Society, he suggested the vineyards and canneries be as sembled at a center, so that there will be enough tonnage to make it's manufacture profitable.
 Would Return End Profits.
 'In the grape juice industry" he said, "the grapes are pressed in or dinary cider presses to obtain the juice. The skins, seeds and p1up re- main in the cloths. The total ton mage of grapes pressed for juice in the grape belts of New York, Ohio and Michigan was ascertained direct ly from the firms for each of the last five years in order to strike a fair average. From these figures, a lO- mace yield of 20 per cent. was ca1- culated, which, in turn, yielded one quarter seed, one quarter dry skins, and one-half water.
 "A method has been worked out and operated in the laboratory on a semi-commercial scale whereby grape seed can be separated from wet grape pomace without recourse to drying. The seed separation will en- able the producer to take out his seed from the balance of the waste at each pulping and pressing station. This makes him independent of the ne cessity of shipping all of his waste to the central plant, when freight rates make such shipment prohibi- tive"
 Because of the shortness of the grape juice pressing season, which lasts from September to November, pr. Shrader has estimated on a plant only large enough to dry the maxi mum amount of seed and then press it in winter months. pr. Shrader cal culated that a, charge of $9 per ton of raw material is allowed for drying and handling from freight cars to storage bins, while $15 to the ton of dry grape seed is allowed for expell- ing the oil and handling from the seed storage to the oil in tanks. This would include all overhead and man. agement charges, except rent of prop erty or interest on real estate invest ment.
 Oil From Other Seeds.
 Dr. Shrader believes that the eff ciency of these plants could be in- creased by also extracting the oil from the seeds of tomatoes as a great many such seeds are rejected in the making of catsup and in canning. Seeds from pumpkins and those from other vegetables, can also be utilized
 Tn this manner chemists are seek ing constantly new ways in which ta increase the supply of oils from vege- table sources as substitutes for ex- pensfve animal fats, and thereby help reduce the cost of living.
