Considerable interest has been shown 

 in these experiment plots by the pea- 

 sants in their districts, and the oper- 

 ations carried out upon them are, to 

 a large extent, followed. The plots 

 were originally chosen in poor areas 

 and where trees have been consider- 

 ably neglected. The Agricultural In- 

 structor uses the plots to meet the 

 peasants aud to show them how agri- 

 cultural operations such as forking, 

 drainage, and pruniug should be carried 

 out, and how manures should be 

 applied. A good crop serves as an ex- 

 cellent object-lesson to all cultivators 

 of cacao, and indicates how the most 

 satisfactory results are to be obtained. 



With regard to the actual results 

 of the experiments, figures are kept 

 as accurately as possible and pub- 

 lished from yeat to year in the Annual 

 Report of the Botanic Station. As 

 a means of obtaining accurate numeri- 

 cal results, the second class of ex- 

 periments, "the experiments stations" 

 afford better opportunitie than the 

 experiment plots, since they are on 

 a bigger scale and are run more on 

 estate lines. 



Three of these stations have complet- 

 ed their first year's course, and the 

 results are briefly set forth in the 

 following table :—
