The first brood was at its height about the middle of July and by th'; 

 end of July slight damage had been done in a few isolated spots 

 (Harmony Hall, Plein Palais, Couva district). The brood was over by 

 the end of July. 



The second brood reached its maximum about the second week in 

 September and caused sudden and wide-spread damage at Couva, 

 K'aroni and Harmony Hall and in isolated areas in the Naparimas. In 

 September and the first half of October the canes were suficring 

 througrhout the Island for want of rain. 



By the beginning of October the second brood of adults had passed, 

 about the middle of the month the weather became much wetter, and, 

 except in certain very badly damaged areas, a rapid recovery set in. 

 The fields became greener and there was no further injury. 



The third brood in November caused little damage except on one 

 estate in the Naparimas, and throughout this month and December 

 recovery was general. 



1919. 



This year was considerably more free from blight than either of the 

 two previous years. 



The broods were earlier (see Fig. 6) and the first brood was at its 

 height at the end of June and beginning of July. Slight damage was 

 recorded at Petit Morne, Woodford Lodge and Harmony Hall.

The second brood was at its height towards the end of August and 

 was locally abundant. Couva district was almost free from damage, 

 but isolated localities in tire Naparimas were damaged and Caroni and 

 Orange Grove in the North both had several fields blighted. 



The third brood was at its height about the 16th-20th October and 

 caused distinct blight in several areas chiefly in th^ Naparimas; Couva 

 district being once more being almost free from injury, both in Farmers' 

 and Estates' canes. 



After this there was a general recovery with fa^■ourable growing 

 weather in November and December.
