Seventy-two thousand tons of oil cake were exported in 1935-36, and in 1936-37, 50,000. Our chief market for the cake has been the United Kingdom, which alone accounted for 70,000 and 47,000 tons for the two years. The sudden improvement in 1934-35 over 1931-32 needs explanation. It has already been pointed out that Argentine is our chief competitor, though viewed from the stand point of quality, the oil content of Indian linseed in much higher. There are two varieties of Indian seed—the Bombay Bold with an oil content of 135 grains per gramme; Calcutta Bold is smaller and has about 145 to 153 grains per gramme. With the falling off in oiir exports and the increasing competition of Argentine, the situation became serious and particularly acute just at the time of the Ottawa Conference. It was therefore thought that something must be done to give the commodity a fillip and this was effected in the shape of a 10% preference to the Indian seed. Coincident with this artificial stimulus, there was a crop failure in Argentine for the two years succeeding 1932, so that our exports shot up and the linseed trade was placed on its old footing. Apart from our rich export trade, there is considerable internal trade in this commodity. Nearly two and a quarter kkhs of tons are available for local consumption. The demand, however, depends upon the reigning prices. Mustard oil is an important adulterant for industrial uses. So that when linseed prices are high, recoOTse is had to mustard oil. It is largely used for culinary purposes and its demand as an edible oil is highest in the Central Provinces which has the largest acreage under the crop. The greatest competitor of linseed is groundnut which will be taken up for consideration later. Thus, it is clear 166
