5 years old, and there were about 900 acres of native grown Para, 
mostly in the Buganda Province. Some 12,000 acres out of the 
17,000 acres of European-owned Para were. interplanted with 
Coffea arabica. Unlike the rubber in the Middle East, there 
is no considerable acreage concentrated in any one spot. ‘“ Even 
in the case of the plantations controlled by the few limited 
companies, the largest compact block barely exceeds 500 acres. 
By far the greater portion of the rubber is distributed as 50 to 
250 acre estates, situated for the most part in the Kiagwe district ”’ 
(Ashplant, p. 3). The low temperatures of high altitudes have 
been found to have a very retarding effect upon the growth of 
Hevea. The yields also become progressively poorer as greater 
elevations are reached. Uganda is said to compare unfavourably 
in these respects with other rubber countries in the East, which 
excepting a few thousand acres in Java, Ceylon and South India 
are within a few hundred feet of sea-level. The Buganda Province 
in which most of the rubber is grown has an annual rainfall of 
only about 50 inches; but the regular distribution of the rainfall 
throughout the year and the high moisture retaining capacity 
of the soils are calculated to do much to make up the deficiency 
(Ashplant, p. 4). ; 
In spacing, when the needs of the two crops have to be allowed 
for, the avenue system, say 15 ft. by 30 ft., offers special ad- 
vantages, but the susceptibility of the local trees to wind damage 
would make such wide gaps inadvisable on Uganda estates, 
where the damage done by windis serious, and, “ all things con- 
sidered, perhaps the best spacing is a modification of the 24 it. 
by 24 ft. system, whereby an extra tree is planted in the middle 
of each square. This system, which has been carried out on 
one or two of the younger estates, permits of the planting of three 
rows of coffee between the lines of rubber and gives approximately 
130 Hevea trees to the acre” (id. p. 19). Nearly all the Para 
rubber in Uganda has been interplanted with Arabian Coffee, 
and so far as one can judge from the appearance of the trees 
everywhere they have not suffered in any way from the compe- 
tition of the Coffee bushes. The rubber tree shade is beneficial 
up to about the sixth year, when it becomes increasingly preju- 
dicial, and after the seventh or eighth year it is doubtful whether 
the small crop of coffee borne is worth the picking. “ The fact that 
coffee can be productive for so long a period under Hevea is 
undoubtedly some compensation for the long wait before the 
rubber becomes revenue-producing in Uganda. Coffee inter- 
planted with rubber in Malaya has to be taken out in the fourth 
year. The ability to grow two important crops like coffee and 
rubber intermingled has, however, not been an unmixed blessing ; 
divided attention has frequently led to one or the other being 
neglected ” (id. p. 17). 
Cultivation, Harvesting, Preparing, Machinery and Diseases 
are also discussed by the respective authors. Lankester concludes 
with the statement that it is inadvisable to brand coffee as “ Costa
