ROADS AND DRAINING. TEMPERATURE AND RAINFALL. 



Cacao. It is different in lands on which cereal crops are annually 

 cultivated, for there the roots seldom or ever reach to the drains 

 during the period of growth, and consequently the drains them- 

 selves work from year to year without let or hindrance. The 

 planter should therefore trust entirely to his surface drainage 

 and make that system do the work to the best advantage. 



TEMPERATURE. 



The temperature required for the growth of the Cacao tree 

 will be best seen from the records of the temperature as taken at 

 the Royal Botanic Gardens, the temperature and humidity being 

 somewhat similar in the various Cacao districts.
