The trees on the various rubber properties enumerated above differ 

 widely in age, size, &c, and are growing in dissimilar climates. 

 The results are, however, of value in so far that they show the yields 

 obtained in an early stage of the industry, when our knowledge 

 is necessarily meagre and our methods open to considerable 

 improvement. 



Kkceptional Yields. 



These results have, however, been completely surpassed by those 

 obtained on exceptional trees during the last few years. Trees of 

 unknown age in Ceylon (probably 20 to 25 years) have given 10, 

 IS, 23, and 25 lb. of rubber in twelve months' time ; other trees, only 

 eleven years old, have in eight months' tapping given 14 lb. of 

 dry rubber each, and others from 2 to 4 lb. in two to three months. 

 Light tapping of young trees has given 1-72 lb. of rubber per tree 

 on a well-known Kalutara property. These results are so significant
