large proportion of the seed is rendered sterile by the 

 cotton seed bug. Grown experimentally on a small scale 

 at Olokemeji, the following results were obtained from 

 several exotic and local cottons (American Middling at 

 6'64d. perlb.) : 



Of the above Nos. 1, 2, 8, 10, 11, 12, 14, 16, 17, 18, 

 and 19 are American varieties, and were grown from 

 seed supplied by the British Cotton Growing Association ; 

 Nos. 4, 5, 6, 13 and 15 are Egyptian ; No. 9 is a Northern 

 Nigerian variety from North Ilorin, and Nos. 3 and 7 

 appear to be local kinds. These cottons are referred to 

 in Professor Dunstan's Report (1907), "British Cotton 

 Cultivation." 



In addition to the susceptibility of the American 

 varieties to the attacks of the local insect pests, the seed 

 produced from plants grown in the country is often 

 sterile. In the districts in the vicinity of the British 

 Cotton Growing Association's ginneries American and 

 native cottons are often seen growing in the same field, 

 but as the time of reaching maturity differs in the various 

 forms, and the cotton is not easily kept separate in the 

 native methods of harvesting, a mixed crop is obtained. 

 Experimenting at the Moor Plantation at Ibadan, the 

 British Cotton Growing Association have obtained occa- 

 sionally satisfactory results from the American plots, as 

 appeared to be the case in the 1908-9 season, when 

 an American " Upland " variety is said to have yielded
