106 TRINIDAD AND TOBAGO BULLETIN. [XIX. 3. 



Tlie principal centre of operations is established at San Jnan, with 

 subsidiary centres in charge of assistants at Curepe and Tunapuna. 

 Eight drivers and about 100 labourers are at present emploj-ed. 



The young canes on the whole area (totalling about 170 acres) have 

 been exanained once and are being worked over again as opportunity 

 occurs. Those in the Curepe district have been rogued twice ; those io 

 the San Juan district three times. The last mentioned, amountmg to 

 about 50 acres, are regarded as being, for the present at least, free from 

 the disease. 



Stubble fields amounting to some BOO acres have been dealt with, 

 either by roguingor clearing as the conditions required. 



The total number of stools destroyed is 44,000, of wliich 6,000 were 

 young canes. The cost of labovn* for this work has been approximately 

 $1,500 and the amount of compensation to be paid according to scale is 

 estimated at $885. For the proportion dealt with the expense is slightly 

 under the estimate on which the grant of funds was based, and it is 

 expected that with the experience which is being gained the cost of 

 operation will be reduced. 



The weather has not been favourable to the campaign. We had hoped 

 for a definite dry season in which the spread of the disease would be 

 entirely stopped, but the figures for the St. Augustine Experiment 

 Station show that the showers of March and April provided conditions 

 under which the process of infection was to some extent resumed. Very 

 much will depend on the time at which the rainy season proper begins. 

 If this were to set in so early as to hamper reaping operations and 

 cause fields to be left over to next crop the cost of operations would be 

 increased and their effectiveness reduced. 



So far the work may be regarded as well in hand and giving as much 

 promise of success as can be expected at tliis stage. 



It is pleasant to report that the farmers have taken our interference 

 with their jiroperty in a good spirit, and serious opposition has in no case 

 been met with.

Implemental Tillagre of Canes. 



During 1920 experimental work has been proceeded with at St. 

 Augustine Experiment Station in continuation of that previously
