tapping. It is to be lioped that this question will be settled dur- 

 ing the experiments which are now being made in different places. 

 In Ceylon the attention is being directed towards profitable tap- 

 ping of the Ceara and a number of experiments are being made. 

 The Bureau of Agriculture and Forestry of these Islands intends 

 to make experiments in tapping Ceara in the small groves of this 

 tree which were planted a number of years ago on the Island of 

 Kauai. In Mexico similar experimxcnts are being made on the 

 only place where Ceara rubber lias been planted in that country, 

 the Esmeralda plantation in Chiapas. This last series of experi- 

 ments is being made in connection with the La Zacualpa Botanical 

 Station. 



In summing up the points expressed above we would say that 

 the area suitable for rubber cultivation in Hawaii is very limited ; 

 only four kinds of rubber are likely to succeed ; the Hevea comes 

 first, with the greatest yield of rubber, Castilla next, Manihot 

 third, and Sapinm is as yet untried ; the limit of elevation for 

 cultivation of these rubber trees in Hawaii ranges approximately 

 as follows : 



Castilla and Hevea from sea level upwards to 500 feet, tlie latter 

 to 800 feet, Manihot up to 1200 and Sapium, not higher than 2000 

 feet. Great care is to be taken in obtaining the right varieties, 

 and in planting under the right conditions. 



POULTRY AND AGRICULTURAL EXHIBITION. 



The Hawaiian Poultry Association will hold its Second Annual 

 Exhibition of Poultry and Pigeons on Thursday, Friday and 

 Saturday, December 20-22nd. The Farmers' Institute of Ha- 

 waii, the Board of Commissioners of Agriculture and Forestry 

 and the Hawaii Experiment Station will also cooperate in the 

 success of the undertaking. Besides the usual contribution of 

 feathered stock, the bee-keepers will be represented, and there 

 will be exhibits of silk culture, beneficial insects, fruits, flowers 

 and ornamental trees. The exhibition will be held in the spaci- 

 ous skating rink on Queen street, not far from Messrs. H. Hack- 

 feld & Co.'s building.
