said: The damage was local and by no means universal, and a localized 

 pest is more easily combated than one' which appears everywhere. 

 Some meadows were entirely free, though for no apparent reasou. On 

 inquiry I could not find that there was any relation whatever between 

 the affected fields and the vicinity of grass land where the Crambus 

 might also live. 



At the time I first visited the spot, Mr. Briggs, thinking it probable 

 that the moth then flying was at the root of the trouble, had lighted 

 torches on the affected bogs, but an examijiation of the tarred stand- 

 ards on which they were placed did not indicate that they had been 

 very effective; at that time, however, to judge from those captured, 

 only mates were flying. Mr. Felt's observatiotis on those captured iu 

 Ithaca in trap lanterns (Bull. 04 Corn. Univ. Agr. Exp. Station) show 

 only fifty-nine captured in thirteen nights between July 5 and 28, of 

 which only eight were females. This mode of attacking, therefore, does 

 not appear very hopeful. 



Experiments made by Mr. Briggs showed that the larvjie would bear 

 submergence in water in the autumn for more than four days without 

 death, and, therefore, no flooding that would not injure the crop could 

 be undertaken at the x>eriod of their greatest ravages. That the win- 

 tering caterpillar within its cocoon can endure any amount of submer- 

 gence is proved by the fact that the flooding of a bog for the entire win- 

 ter does not destroy the pest upon that bog. It would, however, appear 

 probable that as the larvae do not go into cocoons until close to, or in, 

 ^November, and as, by Mr. Briggs' experiments in submerging the bog 

 directly after picking the crop, larvaj were found quite destroyed after 

 five days' immersion, the best means of attacking the insect would be 

 to pick the crop from affected bogs at the earliest time possible, say 

 very early in October at the latest, and immediately to fiood the bog 

 for a full fortnight. As a preventive against any serious outbreak it 

 would be well, wherever the insect has been known to do any damage, 

 to flood all bogs for a week sometime in October. In this way it would 

 seem as if at no time would a crop be likely to suffer any serious dam- 

 age from this insect. A further way, suggested to me by Mr. Briggs, 

 would be, late in aatumn or early in spring, preferably in the former, 

 to thoroughly burn over all territory which had actually been destroyed 

 by the insect, a work which the litter of dead leaves Mould render 

 simple and efficacious. Mr. Briggs has already tried this with success, 

 and has also met with some success in autumn flooding, although he 

 has only tried it for a week or less. A fortnight would hardly injure 

 the plants and would be more surely efficacious. 



To render this account more complete we append tlie few remarks 

 upon it made by Mr. Felt iu his recent account of this insect (/. c, pp. 

 75, 76): 



The species is very prolific; one female laid seven hundred eggs, three hundred 

 being laid the first day. This is undoubtedly above the average. The eggs hatch
