side walls could be easily made air-tight, and 

 then heat was brought to the produce from a 

 furnace at the other end of the shed by passing 

 it, i.e., the heat, through a pipe or pipes placed 

 under the lowest trays. Such a drying shed 

 was first erected in the Cameroons on the 

 Kriegsschiffhafen plantation. 



In other countries large stationary platforms 

 (known as cacao-house floors), capable of being 

 used for sun or artificial drying are erected. 

 A movable roof renders sun-drying possible, 

 whilst heating pipes under the floor do the 

 same when artificial drying is needed. A 

 drying-house constructed according to this, the 

 Trinidad (W.I.) system, is to be found in the 

 Botanical Gardens in the Cameroons. It has, 

 however, proved a complete failure owing 

 probably to those using it misunderstanding 

 some detail in the heating, or having omitted 

 its use. 1 At a subsequent date drying-houses 

 were built on some of the estates in the 

 Cameroons, fitted with the movable trays to 

 be met with in the Trinidad drying-houses. 



In cacao growing countries where the main 

 crop coincides with the rainy season, sun- 

 drying is practically out of the question, and 

 artificial drying has therefore to be exclusively 



1 Such a system was not considered to have proved 

 successful in Trinidad (W.I.), at any rate not on the 

 San Salvador estate, one reason being that the aper- 

 tures got choked up and so prevented the warm air 

 getting at the beans. H. H. S.
