treated with tar, as Nectria is a woimdparasite and the 

 spores should not be given an opportiinity of penetrating 

 into the tissues. C a r r u t h e r s disagreed with the application 

 of tar, as it might prevent the control of the excised spots. 



In the West Indies the number of cankercases has also 

 diminished, although the disease has not been eradicated. 



In Suriname cankerpatches are generally excised; after 

 this the wound is left uncovered for some days to let it dry, 

 and then tarred. A tree often recovers after this, sometimes 

 it does not. As has ah-eady been remarked, trees also 

 recovered in many instances without any treatment at ail. 



As it is probable that the serions character which the 

 disease assumed in Suriname in 1907, was due to the 

 trees having stood for a long time in stagnant water, the 

 treatment hère should in the first place be directed towards 

 the prévention of such conditions, or in other words, the 

 cacaofields must be well drained and the dams so well 

 attended to, that there can be no danger of rupture in 

 case the water should again rise abnormally. 



Although it is certain that trees can recover without 

 excision of the diseased tissues, we know as yet too 

 little about this to dare trust to it alone. Therefore the 

 old treatment of carefully looking for diseased spots and 

 excising them and removing trees killed by the disease, 

 must for the présent be recommended as being the safest 

 method.
