efficiently removed by polishing, and even that 

 does not always prevent this blemish from 

 sometimes penetrating to the interior of the 

 seed. It would probably be useful to follow the 

 procedure used in military stables, and incor- 

 porate an appreciable quantity of powdered 

 sulphate of copper in the upper "rendering" 

 of the concrete floor. Where a wooden floor 

 already exists, a covering of very thin copper 

 sheeting, with as few joins as possible, would 

 probably prove advantageous. The idea is to 

 provide a surface free from cracks, in which 

 mildew spores cannot persist, and which can 

 be effectively cleansed with a bucket of water 

 and a hard broom. 



As to the space required per 100 bags of 

 cacao, no hard and fast rule can be adopted. 

 Some estates get more than half their crop 

 within a few months of the year, 1 other estates 

 with lighter soil and younger trees divide the 

 crop much more equitably throughout the year. 

 Again, some estates near the sea coast or on 

 flat, open land get much more sun and less rain 

 than other plantations situated up in the hills. 

 Without auxiliary artificial heating probably 

 5 superficial sq. ft. per cwt. of dry cacao, 

 produced would not be excessive. With an 

 auxiliary hot-air chamber or machine, probably 



1 The Gold Coast returns, for instance, show that out 

 of an export of about 40,000 tons cacao, some 28,000 

 tons, or 70 per cent., were exported in the four months 

 November-February.
