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 reason. 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 examination 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 males were flying. Mr. Felt's observations on those captured in 
Ithaca in trap lanterns (Bull. 64 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 larvae would bear 
submergence in water in the autumn for more than four days without 
death, aud, therefore, no flooding that would not injure the crop could 
be undertaken at the period 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, larvae 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 flood 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 autumn 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 would 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 in jure 
the plants and would be more surely efficacious. 
To render this account more complete we append the few remarks 
upon it made by Mr. Felt in his recent account of this insect (/. <■.. 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 eggB hatch
