be exceeded with less cash expenditure 

 and a reduction in the amount of 

 bark used up in tapping. Judging from 

 the good results obtained during 1908 

 there seems every likelhood of our fore- 

 casted yield of " one ton per ten acres " 

 being well maintained after the eighth 

 year on most of the well-managed 

 plantations. 



Total Annual Yields, 



The simplest way to deal with this 

 subject is to tabulate the total yields 

 obtained on well-known estates. A few 

 statistics have already been published, 

 and as additional information has now 

 been gleaned, the following statement 

 will be of value :—

Yield per Acre. 



The above list is useful in so far that 

 it shows the progress, in yielding capa- 

 city, of the properties owned by different 

 companies. It is, however, not so use- 

 ful as it might be since it does not 

 afford any definite information ot the 

 yield from previously tapped areas, or 

 the actual acreage operated upon, On 



[November, 1909. 



past occasions most companies have, in 

 their annual reports, given information 

 of the number of trees tapped and 

 therefore of the yield per tree ; the Kuala 

 Selangore, Malay States Coffee, Rubber 

 Growers, Selangore Rubber, and Seram- 

 ban Estate Rubber Companies have on 

 previous occasions given the yield per 

 acre. In order to show the crops ob- 

 tained from parts of estates planted 

 at different distances, the Vallambrosa 

 Rubber Co. and Highlands and Low- 

 lands Estates have similarly detailed 

 the yield per acre on small areas. In- 

 formation of this character is of the 

 utmost value, as it enables investors and 

 buyers to more accurately determine 

 the real position of affairs. We trust 

 that the directors of companies who have 

 bearing estates in their charge will 

 make a point of giving the yield per acre 

 in their annual reports now in course 

 of preparation. The figures may not 

 always appear very attractive when 

 they relate to the yields obtained during 

 the first crop, but they will ultimately 

 be very serviceable, especially when the 

 maximum yield has been attained. 



At the present time we are not in 

 possession of reliable information which 

 would enable us to say when a given 

 acreage is yielding the minimum, medium 

 or maximum crop, though this know- 

 ledge is, for obvious reasons, desirable. 

 The differences in recorded yields appear 

 enormous, because the number of trees 

 instead of acreages have been usually 

 quoted, the trees being scattered over 

 very large areas. In some cases a yield 

 of 1 lb. per tree has been obtained from 

 trees four years old, but only those fami- 

 liar with details know that such trees 

 form only a small percentage per acre. 

 It should not be difficult to compile a 

 statement showing the yield and per- 

 centage number of trees tapped per 

 acre, each year, until all the trees on a 

 given acreage attain the tappable size, 

 after that period there is no other course 

 open than to record the yield per acre 

 per annum for fields of known age. It 

 is already apparent that some parts of 

 Malaya are probably more favourable 

 for rubber cultivation than others, but 

 information of the annual yielding 

 capacity of mature acreage since the 

 year they were first tapped would reveal 

 the superiority of one district over 

 another, and thus serve a very useful 

 purpose in the event of future exten- 

 sions being contemplated. This sounds 

 very much like scientific land selection 

 when it is too late ; but to those who 

 take that view we would say that 

 actual results would form the best basis 

 to work upon.
