This is the common worm seen in every soil in pots and in the open ground. It is harmless so far as feeding goes, for it seems never to touch plants as food, but it bores and crawls around in a way by no means beneficial to pot-grown plants; it is, however, easily dislodged; by slaking a quart of lime and adding water to make up ten gallons of the liquid, and watering the plants with it after it has become clear, the caustic qualities of the lime will be quickly fatal to the worm.
