Entebbe, where tapping results have proved fairly satisfactory. 

 On November 14, 1908, tapping was commenced on two trees 

 one seven years old and the other four. They were tapped 

 for a period of 59 days and gave 4*7 oz. and 4*3 oz. of dry 

 rubber respectively. It was then estimated that I Ib. of dry 

 rubber per tree per annum could be confidently expected. 



Further experiments have proved this, as during 1912, 164 

 trees were tapped 41 times in the same Gardens, and averaged 

 13 oz. of dry rubber per tree. The trees were 8 years old, 

 and the methods of tapping were various and entirely 

 experimental. 



On January i, 1913, after uie trees in the Gardens had been 

 rested for 9 months, tapping was re-started on 310 trees, and 

 the yield of dry rubber averaged 13! oz. per tree to March 31, 

 1913; during this period the trees were tapped 71 times. 



On the Kivuvu Estate in 1913 Messrs. Brown and Hunter 

 carried out tapping experiments on commercial lines, 1,800 

 trees on an average being tapped per month for four months. 

 The trees were 5 years old, and the method of tapping was one 

 basal V-cut. The average yield per tree for that period was 



5'i3 oz - 



The trees showed no ill-effects from the tapping and were 



rapidly putting on girth, whilst Mr. Brown informed me that 

 the cost of production on the estate was well under is. per Ib. 

 The area under Hevea brasiliensis is increasing more rapidly 

 than all the other kinds of rubber taken together. 



[DISCUSSION.] 



In reply to questions Mr. Simpson stated that Coffea lib erica 

 was being grown on the Hevea plantations in Uganda, but 

 that speaking generally he was not in favour of planting this 

 variety along with rubber trees; for this purpose he preferred 

 C. robusta. 



It had been found impossible to grow Castilloa trees success- 

 fully in Uganda owing to the presence of a lepidopterous insect 

 which attacks the top shoots and prevents the tree from 

 growing. 



Funtumia elastica is indigenous to Uganda and most of the 

 rubber exported from the forests is from F. elastica trees. 

 Some of the planters started to grow this species in planta- 

 tions, but it takes so long to come to maturity, and the yield 

 of rubber is so small, that it is hardly advantageous from the 

 planters' point of view. They have therefore given up 

 Funtumia entirely and are now sticking to Hevea brasiliensis.
