find this is a mistake. Neither grows as thick as either 

 would have done if alone. The foliage of each is one side 

 only and such trees being lop-sided are very liable to suffer 

 from wind. 



"Warts" and "Peas." 



The growths, commonly called "warts" or "peas," 

 are to be found on nearly all trees. Tapping does not 

 appear to induce them as they are found on untapped trees 

 of three years and older. L believe they are dormant buds. 

 They should be taken out when quite young; this is easily 

 done by a tap from a hammer or with a strong knife. The 

 wound soon heals over completely. The practice of many 

 planters having their old trees examined systematically at 

 periodica] intervals for these excrescences is worthy of 

 wider application. The rough outgrowths, often several 

 square inches or even square feet in area, which usually 

 begin at the bottom on trees where the early tapping has 

 been bad, seem to be a disease not due to any parasitic 

 organism but to some derangement in the internal economy 

 of the tree induced perhaps by severe tapping.

With regard to distance in planting it is of interest to 

 record that on Caledonia Estate 378 lbs. of dry rubber per 

 acre was obtained in one year from seven year old trees, 

 planted 10 feet by 10 feet.

PACKING DURIAN SEEDS FOR EXPORT. 



During the past year several experiments have been 

 carried out at the Botanic Gardens, Singapore, in order to 

 determine the best method of packing Durian (Durio 

 zibetliiiius) seeds for export to other tropical Colonies. 

 Hitherto it had been thought that seeds of this much sought 

 for fruit would not travel any distance successfully owing 

 to it germinating so quickly after becoming ripe and there 

 would appear to be some grounds for this assumption, in 

 fact several attempts were made in years past to send seeds 

 from this Department to Ceylon with scanty success. 

 These failures must however, have been due to a want of 

 knowledge as to the proper method of packing and not so 

 much to the inability of the seeds to retain their germinat- 

 ing powers for any lengthy period.
