In its March number the PhiHppine Agricultural Review gives, 
from the census reports, a synopsis of the development of the 
sugar industry in Hawaii, translating values into Philippine 
terms. 
An exchange quotes the Straits Bulletin as containing an 
article by Dr. Boon Keng recommending pineapples as a good 
catch-crop between Hevea rubber trees, if widely planted. With 
the trees set 30 by 15 feet apart, "the pineapples should be planted 
three feet away from each rubber plant, and the lines should be 
arranged on hill slopes that they serve as terraces to prevent too 
much wash from rain water. In this way we can get in, say, 
about 2000 pineapple plants in an acre." 
In a collection of banana planting news, Tropical Life for April 
states that, from the results now published regarding the indus- 
try in Trinidad, W. I., "it appears probable that a profit of $200 
per acre may be expected from the intensive cultivation of ba- 
nanas under the present conditions and prices if an adequate 
dressing of pen manure is available at a reasonable cost. The 
cheapest method of obtaining pen manure is from pens on the 
cultivation, and with a supply of green fodder within reasonable 
distances a small profit on the stock might also be expected." 
Noel Deerr is author of a new book entitled Cane Sugar, which 
a review in the Agricultural News (W. I.) says 'Virtually forms 
a new and extended edition of the author's well-known text-book 
Sugar and the Sugar Cane." Mentioning various matters treated 
in one chapter, the review says that irrigation "naturally occu- 
pies a fairly prominent position in view of the author's experi- 
ence in Hawaii." Fault is found with the handling of rotation, 
in that "there is very scant reference to its bearing on the control 
of insect and fungus pests." Norman Rodger, Altrincham; is 
the publisher. 
Mr. Tames is welcomed as a contributor to The Forester's 
pages of practical information. His article on the efifect of fer- 
tilizers on the growth of pineapples can scarcely fail to prove of 
highest value to the pineapple industry. It is based upon ex- 
periment on a considerably large scale. A series of articles on 
the same subject, it mav be mentioned, is running in the Trop- 
ical Agriculturist of Ceylon, the leading topic of the portion 
given in March being "the efifect of fertilizers upon the quality 
of tlie fruit." A. W. Blair and R. N. Wilson are the authors, 
and their plotting of the ground appears to be much like that of 
Mr. James. Blood, which Mr. James dismisses on account of its 
being practically unavailable, enters into nearly all of the fer- 
tilizes tested by the Ceylon experimenters.
