GROWING GOLD 



planted in lines cut through the viring forest which 

 had been heavily exploited during the last twenty years. 

 The planting showed good results, 95 per cent, suc- 

 ceeding. 



Wherever pure plantations of Khaya species mahogany 

 were attempted, they failed. It proved that this valuable 

 species needed nurse trees through the whole of its life 

 to bring it to maturity. 



Under Walsh's System thirty acres were dealt with, 

 but owing to an incomplete burn over, results were not 

 as satisfactory as might have been expected. As this 

 system entails the felling of all the inferior species, the 

 cost is consequently high in a forest where few other 

 species than those provided by the melliaceous group are 

 utilized. 



In addition to the experiments carried out within 

 the Working Area, thirty blanks caused by felling in an 

 adjoining concession are being treated annually under 

 the Selection Group System. All the species before men- 

 tioned were also treated under this system, and although 

 it is too early to draw any conclusion from the results 

 obtained, it is interesting to observe that in thirty groups 

 treated there are only four failures. The natural regen- 

 eration was more often from seed from neighbouring 

 mother trees surrounding the blank than from the tree 

 which had been extracted. 



Perhaps one of the most interesting experiments at 

 Sapoba is the introduction of Chena Cultivators. 

 Twenty-six acres of inferior bush was chosen for this
