The total number of trees distributed for Arbor Day, 1911,

 is almost exhausted. We have, however, a large number of forest 

 and windbreak trees still in stock.

This work, as carried on at Dominica, is at present in its initial 

 stages, but some benefit might be derived by placing on record the 

 work that has so far been accomplished in the attempt to raise im- 

 proved varieties of mangoes from seed. 



There are numerous seedling mango trees to be found in most 

 of the West Indian islands, the fruit of many being quite value-

This variation, or failing to breed true, in seedling mangoes 

 is due to indiscriminate cross-fertilization such as obtains in locali-
