IDEAL FOR TROPICAL AGRICULTURISTS 



overcome, So far the yields of rubber from ma- 

 ture trees on African plantations have been 

 small. Funtumia elastica appears to behave 

 very much like Ficus elastica ( Kambong) in so far 

 that copious yields on first tappings give way 

 to unprofitable yields very quickly, and a long 

 rest is necessary before economical tapping can 

 be indulged in. Manihot, to judge from the 

 published reports of well-known East African 

 companies, does not give more than 12 to 15 

 ounces per tree per auuum. Such yields com- 

 pare very badly with those from three to four 

 year old Hevea treeo in Malaya ; when contras- 

 ted with the yields from older Hevea trees in 

 the East they make a very poor showing. 



HIGH YIELDS IN THE EAST. 



It is true that some Eastern estates appear to 

 have been tapped as vigorously as they possibly 

 could, and perhaps the high yields recorded in 

 the past will not be annually repeated ; should 

 this transpire, the Manihot and Funtumia trees 



may be in a better position, comparatively 



There is no clear statement that the trees of the 

 Pataling Rubber Estates had been overtapped, 

 but the trend of the Chairman's remark is very 

 much to the effect. That a.company paying such 

 large and handsome dividends should, in its 

 ninth year of existence, have to admit that tap- 

 ping overhead had been adopted is serious. 

 There may be some excuse for young companies, 

 having no previous experience, and being de- 

 mroua of entering the dividend stage, tapping 

 the trees in an exacting manner j but there can 



be no satisfactory explanation of such faulty 



work on estates as old as Pataling Tapping 



operations have a marked effect on the reserve 

 food supplies and the recuperative powers of the 

 trees. Drastic or too frequent tapping, whether 

 of Hevea, Manihot, or Funtumia trees, means a 

 lowering of annual yields and premature death. 

 A long and healthy life for the trees should be 

 aimed at. This can only be assured by removing 

 the minimum quantity of bark and allowing the 

 maximum period of time for renewal of bark.

CAMPHOR IN INDIA'S WETTEST 

 DISTRICT. 



The camphor trees planted in the Government 

 Farm at Wahjian below the plateau of Cherra- 

 punji, have now reached a stage fit for cutting 

 for distribution, and experiments were started 

 in May last. A small still, modelled on those 

 used in Ceylon, ' was constructed at a cost of 

 Rs. 80. In the first trial distillation 35 lb. of 

 twigs and leaves yielded If oz. of crude cam- 

 phor. Of experiments in propagating the 

 camphor trees by rcot cuttings and layeringa 

 out of 30 root cuttings put down at the com- 

 mencement of the rains, 20 have succeeded and 

 out of 50 layers 10 have proved successful.—
