seed oil in painting, owing to its lower price. It dries 

 more slowly than linseed oil. Manufacturers are en- 

 deavoring 10 increase the supply of corn oil, for 

 use in the mechanic arts, by the aid of a naphtha and 

 steam process long followed in France in extracting 

 vegetable oils. Some progress has been made in the 

 use of corn oil in producing a substitute for rubber by 

 a process of vulcanization. Vulcanized corn oil may be 

 mixed with pure rubber in various proportions, the 

 resultant being softer and less elastic than pure rubber, 

 but also equally acid proof. It enters into the manu- 

 facture of rubber boots, bicycle tires, etc, greatly re- 

 ducing the cost of the finished product. It is not as 

 good as rubber. 



Considerable quantities of corn oil are now ex- 

 ported, chiefly to Belgium, Holland, and the United 

 Kingdom, in about the order named. In the fiscal year 

 1902 exports of corn oil from the United States were 

 4,266,398 gallons, at an average value of forty-one and 

 one-half cents; of this 2,933,650 gallons went to Bel- 

 gium. In 1901 exports were 4,808,545 gallons, having 

 an average value of thirty-eight cents; of this amount 

 3,005,000 gallons went to Belgium. Total exports 

 in 1900 were 4,383,926 gallons, in 1899 2,360,623 gal- 

 lons and in 1898 2,646,560 gallons. 



FOREIGN OUTLET FOR AMERICAN CORN 



Our foreign trade in corn has assumed important 

 proportions and is in a most healthy condition. Never 

 firmer established than now, exports following a good 

 crop easily approximate 200,000,000 bushels in a year. 

 When prices are unusually high in seasons following 

 a domestic crop shortage, as was the case in 1902, 1894 

 and 1891, exports are materially reduced. 



Up to the present, the foreign use of corn is con-
