At Ibadan an oil mill has been erected in connection with the Marlborough Ginnery, and the expression of oil from the seed is regularly carried on. The seed cake which is turned out is found to be of rather inferior quality for European consumption, as the excess of woolly seed renders it undesirable for cattle food. A very economical local use for this cake has recently been discovered—namely the employment of it to generate gas to drive the machinery of the ginnery. It has been found that 6 cwt. of cotton-seed cake is sufficient to generate gas to drive the 30 h.p. oil-mill engine for nine and a half hours. This discovery suggests the possibility of doing without coal entirely at the ginneries, which would mean a very large saving in the cost of production of cotton. The cotton ginned by the British Cotton Growing Association is baled for the most part in rectangular oblong form, each bale weighing approximately 400 lbs. The production of the country has shown a rapid increase, especially in the earlier years, though more recently one of the seasons proved a short one owing to adverse climatic conditions.

(“Cotton Varieties,” cf. _Bull. Imp. Inst._, vol. xv. [1917]). Much is expected from this new development. =MAIZE.=—In the last few years the cultivation of a short-season “white” maize has been taken up, especially among the Yorubas, in the Western Province, although the variety is also found in the fields farther to the east.

Various methods have been suggested to remedy this, including disinfection with carbon bisulphide, but the use of this last is dangerous.
