is limited to regions free from frost, and delights in a deep rich 

 soil and abundant moisture. There are many places in the 

 West Indies and elsewhere in tropical America where it should 

 be quite at home. In the Malayan islands, where it is com- 

 monly grown, the tree receives little cultural attention, hence 

 nothing is known regarding pruning, irrigation, or other matters 

 which usually give the northern horticulturists much concern. 

 Propagation is ordinarily by seeds, which do not keep long 

 after they are removed from the fruit. It has been learned 

 that they can be shipped successfully from the eastern to the 

 western tropics if they are packed in a mixture of charcoal 

 and coconut fiber, slightly moistened. 



The method of budding practiced by Wester, to which refer- 

 ence has been made, differs very little from shield-budding as 

 applied to the avocado and mango. By means of this method 

 of propagation it will be possible to perpetuate superior seed- 

 lings, and the number of years required for the tree to come 

 into bearing should be lessened. Wester recommends that 

 the budwood be well beyond the tender stage, but not so old 

 that it is brittle. The petioles should be removed some time 

 before the budwood is to be used, and the petiole-scars given 

 time to heal over; if this is not done, decay may attack the 

 buds. The inverted T-incision is preferred. 



No horticultural varieties have yet been established, but 

 several seedling races or forms are known to exist. Barrett 

 says : " In passing we should not forget that there are durians 

 and durians; some are said to be without a strong odor, while 

 to our certain knowledge some of the Borneo varieties are not 

 at all objectionable. Borneo has at least six and probably 

 ten varieties; some of these have only one or two seeds and 

 are comparatively small fruits, while others are fully as large 

 as our largest Jolo or Lake Lanao (Mindanao) forms ; the pulp 

 of some is nearly white, while that of others is pale salmon or 

 even orange in color,"
