Having mastered the method of extracting oil from the seeds, you can get oil even from the tree branches.
Four-year linden or birch twigs (age branches known by the number of layers that are visible in cross sections of branches) crush on a grater.
Crushed pulp is poured sulfuric ether or gasoline, and insist closed for two days. After a lot of squeeze, ether or gasoline poured into the flask or cup and at Greve in hot water, driving them away from oil. To make sure that we got a really oil, soak a piece of paper or their fleece, cloth, and light the wick, oil burning.
The oil is obtained from the branches, cut in late autumn or winter after the frosts. Only in winter in branches formed fats that help the tree to resist the action of frost.
Here we have found you in the woods and cereal for porridge, and oil.
