REMEDIES AGAINST HIE FIRE WORM 21 



cases they proved to be impregnated, but none laid eggs until the second 

 day. and on examining the vines it was not until four days after the 

 moths first appeared that I succeeded in (hiding an egg. There are^ 

 therefore, certainly two or three days during which, if the moths can 

 be caught, they may be prevented from laying eggs. There was a space 

 of a few rods on one of Dr. Brakeley's bogs on which the moths appeared 

 very abundantly. At first, with the moth-catcher used by him. and 

 which it required two men at least to manage, several hundred were 

 caught in an evening, but 80 many escaped that I suggested large hand- 

 nets; these were made about 14 inches in diameter, of mosquito-netting 

 doubled, and with handles about six feet in length : three men were 

 armed and sent to the infested place, and each caught several thousand — 

 estimate. 



There is only an hour and a half or two hours just before dark when 

 this method can be employed, for during the day the moths tin not rise; 

 but just before and during the twilight they are easily disturbed and 

 will readily rise, flying low and slowly, and hovering very much like 

 mosquitos. which, by the by, often made their presence among them 

 unpleasantly prominent. Walking slowly over the bog, hundreds of 

 them are disturbed and rise up before one, and by sweeping with the 

 net from side to side, and just over the vines, the great majority of them 

 can be caught. Two or three evenings will suffice to clear as large a 

 spot as there is force to get over, and if the retreat of the water has 

 been gradual the moths will appear in most abundance a day or two 

 apart at different points, and time to combat them will be gained. It 

 must be borne in uiiud that every female destroyed in time lessens the 

 second brood by 20 to 25, and may save just that number of berries. 



The moths of this brood disappear in about eight days, though s* 

 glers remain much later, and where the water has been gradually with- 

 drawn, as recommended, the broods may lap. After the moths entirely 

 disappear the vines should be closely examined for eggs; if they are 

 found abundant, and the vines are not in blossom or the buds fully 

 formed, a heavy dose of kerosene should be applied, which will destroy 

 most of the eggs. If the buds are fully formed or the vines have begun 

 to blossom it is not advisable to apply kerosene, as it may retard the 

 development or injure the buds or blossoms. If all these measures have 

 been carefully taken the second brood will be very light, and will do 

 very little damage, even if not further disturbed: but the tight should 

 not be abandoned here : watch closely for the first appearance of the 

 second brood, which will probably be simultaneous with the blossoming 

 of the vim-s. As already stated, the insect lives for a few days exposed, 

 eating buds, blossoms, and young berries; its work can be noted by 

 prematurely brown, dried-up blossoms, and the insert should now be 

 attacked either by pyrethrum or Paris green, preferably the former. If 

 pyrethrum be used it should be mixed with two and a half times its 

 weight of poor Hour, allowed to stand twenty-four hours in a close ves 

 sel, and liberally applied when the vines are dry. It is now compara
