HAWAIIAN RUBBER. 
The Ccara Rubber Tree in Hawaii, by Jared G. Smith, Special 
Agent in Charge of the Hawaii Experiment Station, and Q. Q. 
Bradford, Assistant in Rubber Investigations. 
The above publication commences with a succinct account of the 
habit of growth and root and latex systems of the Ceara rubber 
tree and furnishes full cultural directions for the establishment 
of a plantation. 
An interesting account of various systems of tapping is then 
given and of the' methods of coagulating the latex and preparing 
the rubber for market. 
To the Hawaiian agriculturist probably the most important 
part of the work will be found in that devoted to the actual tap- 
ping experiments on Kauai, where as is well known two groves 
of Ceara rubber trees were discovered in 1906, one at Lihue and 
another at Koloa. 
Tapping experiments were begun at Lihue in January, 1907, 
these being fully described in the publication. So far as opera- 
tions have been undertaken to determine the latex yield of rubber 
trees in the islands (upon Kauai, Oahu and Hawaii) a very wide 
variation of results is noticed, and it is essential that this question 
be investigated with a view to establishing a system of securing 
a uniform and satisfactory yield. 
The chapter devoted to the outlook for rubber contains much 
to encourage the belief that this crop is likely to well repay in- 
vestment when plantations are conducted under proper climatic 
conditions. 
"The Ceara Rubber Tree," in Hawaii is Bulletin No. 16 of the 
Hawaii Agricultural Experiment Station. 
HAWAIIAN HONEY. 
Hazcaiian Honeys, by D. L. Van Dine, Entomologist, and Alice 
R. Thompson, Assistant Chemist, Hawaii Agricultural Experi- 
ment Station. 
The report that Hawaiian honey was not favorably received in 
the mainland and the London markets, caused the Hawaii Ex- 
periment Station in 1905 to commence a detailed study of the 
source and characteristics of our local honeys. The investigations 
show that although Hawaiian honey sometimes departs mate- 
rially from the official definition of honey, this fact is to be at- 
tributed not to adulteration, but to sources or characters till now 
little understood. 
The importance of the information derived from ^ecent investi- 
gations, and its bearing on the marketing of Hawaiian honey, have 
rendered it advisable to make this the subject of che Bulletin in 
question rather than reserve it for a larger work on Hawaiian 
apiculture.
