The viiluo of ants in interposing cliccks to the excessive increase of the fall army worm in the South was known in Glover's time, and especial mention is made of them in his report for 1S55 (3). Ants are also mentioned by our correspondents as being efficacious in destroy- ing this pest. Of the operations of ants as destroyers of the "grass-worm" Glover says that on a plantation in the vicinity of muu- erous colonies had formed their holes or nests in the road passing through the c«Miter of an infested field and here lay in wait for any unfortunate caterpillar which should be tempted- to cross this dan- gerous path for a fresh supply of food. First, one ant more vigilant than the rest woultl rush to the attack; then anotlier, and another, until the poor caterpillar, entirely covered by its pigmy foes, and com- pletely exhausted in strength by its unavailing efforts to escape, was finally obliged to suecumb to superior numbers and die as quietly as possible, when the carcass was immediately carried off l)y the captors to their nests, or, when too heavy to be â¢Iragged away at once, they fed upon it as it lay in the road. This warfare Mas carried on every day as long as the grass-worms prevailed, and no doubt their numl)ers were diminishe<l in tiiis way to a considerable extent.
