and the actual tapping was done by Mr. Q. Q. Bradford, Assistant m 
Rubber Investigations, and the labourers under his direction. In ^ 
reDort Mr Wilcox acknowledges the active co-operation of the direc 
tors of the four rubber plantations on Maui in allowing their trees to 
^experimented on, and in furnishing the labourers and accommoda- 
tions for Mr. Bradford when carrying out the experiments. 
“While fertilizers have been used in rubber plantations for 
increasing the growth and vigour of rubber trees, we have found n 
record of experiments to determine the possibility of increasing 
flow of latex temporarily during the tapping period. It is 
that if the flow can be considerably increased by the application of a 
Quick-acting ferti izer, economy will be secured in the opera ions of 
^Tping and collecting latex. The first experiment with nitrate of 
soda was carried out at Keanae, Maui, on Ceara rubber trees a J, ® d 
ing 14 in. in circumference. A uniform series of trees was found and 
divided into three groups which received ^ lb., A lb " “‘Lj 
of soda respectively. Before applying the nitrate of soda, the yield 
of the whole group of trees was tested by means of uniform tapping.
