Thus vaseline oil is a by-product in the manufacture of vaseline, and has been used for the same medicinal purposes for many years. There is no other product of petroleum manufactured abroad which is not also manufactured in the United States. Arrangements have been completed whereby American alboline will be on the United States market in quantity before the end of the present calendar year, whether hostilities cease or not. One of the products of petroleum that has been exported to a value between $9,000,000 and $10,000,000 during the last three years is paraffin wax. In spite of these large exports, natural mineral wax (ozokerite) is imported, for the reason that its melting point is very high, and although the paraffin wax from petroleum can be produced with this high melting point, the process is difficult and costly. Ozokerite occurs in considerable quantity in Utah in the region of Soldiers Summit, and has been produced there, but the cost of extracting it from low-grade material, together with the cost of transportation to the market, which is chiefly in the Eastern States, has made it possible for the foreign material, which comes from Galicia, to compete with it successfully. The domestic ozokerite should now replace the foreign material. Another material related to petroleum which has long furnished a large import trade is asphalt from the island of Trinidad. This trade has persisted in spite of the very large developments of asphalt from the residue of asphaltic oils, and even under the war conditions the imports will undoubtedly continue. The importation of one product of asphalt, however, has now been cut off, and that is Ichthyol, a peculiar asphaltic material found in Austria, which finds application after appropriate chemical treat ment as a very important medicament. The raw material comes from a fossiliferons deposit near Seefeld, in the Austrian Tyrol. It is carefully selected and subjected to dry distillation. The distillate thus obtained is then sulphonated and subsequently neutralized with ammonia. The use of this material has greatly increased in the last few years, and it has proved very beneficial. Since the beginning of the war its price has doubled, going to over GO cents an ounce. Already a firm in St. Louis has a material on the market which has been favorably recommended as an efficient substitute closely resem bling ichthyol itself.
