of treatment which was steadily pursued for two years. Every person 
t, viz., the grub, the chrysalis, and the mature 
insect. A small sum was offered for these and payment was made at 
the close of each day. During one month (February 1893) there were 
destroyed 46,884 insects in various stages. During the rest of the year 
the numbers were not so large, but the record kept of them shows that 
9,640 grubs were eut out of standing canes, 5,022 were destroyed in the 
chrysalis stage, and 1,144 moths were caught on the wing. By judicious 
management and personal influence Mr. Tonge has so thoroughly 
enlisted the interest of the workpeople that the moth-borer is becoming 
less and less plentiful. Its practical extermination on this estate is now 
only a question of time. e period during which the canes are 
growing appears to be the most critical time. Women and children are 
were regularly pursued in the West Indies for two or three seasons 
the injuries would be reduced within comparatively small dimensions. 
As regards other means for destroying the moth-borer, Mr. Barber, in 
his letter already cited, has added the following interesting points which 
deserve consideration. These do not, however, show tbat the planter 
should relax his efforts to cut out the grubs in the standing canes. 
Nothing can do away with the necessity for this. Mr. Barber's 
remarks exhibit a careful study of the habits of the insect, and draw 
particular attention to the need for adopting only such remedies as are 
suited to local circumstances. Countries situated in the tropics, where 
there is no winter’s rest for the es, obviously require a different 
treatment from that found suitable in the southern United States and 
others where canes are only growing during about seven or eight months 
in the year. In these respects the remedies suggested in the extract 
from the Indian Museum Notes requires some modification. 
Mr. Barber remarked, in his Report to the Government, of April 
16th ;— 
“The question of burning has, I believe, been much obscured by the 
practice in other sugar-growing countries. In the United States there 
is a winter, the moth-borer hibernating as a grub in the cane; and the 
burning of the stubble and all dead canes will probably be of service. 
In Mauritius the moth-borer is credited with spinning a loose cocoon in 
the trash, and burning the trash will probably be very effective in 
destroying it. This is quite sufficient to determine the Mauritius borer 
as different from ours. I have not at present met with any stage of our 
borer in the trash; it changes from grub to moth in the burrows in the 
cane, : 
“ I recommend a study of parasites of the moth-borer. At present 
a fungus, attacking it in its burrows, does us good service. In one case 
detected 13 dead grubs in three Caledonian Queen canes, These were
