CLEARING AND PLANTING 71 



yet sufficiently extended to entitle anyone to dog- 

 matise on the subject. The experience gained in 

 other countries can be useful only as a guide in the 

 conduct of our own experiments. The nature of 

 the soil of the individual estate is a factor which 

 may upset any general rule. On a poor soil more 

 trees per acre may be planted than on a rich soil. 

 The following distances are, as far as our 

 experience goes, the best to work from : 



Para Rubber alone ... ... 20 / x20 / . 



Cocoa ... ... ... ... 13'xlO'. 



Coffee, Nyasa variety ... ... 8'x 6'. 



Coffee, Bourbon variety ... ... 8'x 8'. 



Para Rubber int 3rplanted with Coffee... 24 / x24 / . 



This spacing will, we believe, allow the Coffee 

 and Para Rubber to reach the maximum size in 

 good soil. With Cocoa it will probably be found 

 necessary to cut out every other tree after 12 or 15 

 years. This will leave the trees finally 13' * 20', 

 which we do not think will be found too great tu 

 distance eventually, although it would be much 

 too great up to the twelfth year. The planting of 

 the trees at 10 feet will allow of almost double the 

 crop being secured from the area for several years, 

 and with the closer planting, upkeep expenses will
