Agricultural Experiment Station; Agriculture -- New York (State). Rural School Leaflet 899 greatly in controlling this cabbage pest. Very often one of the dead green caterpillars is found attached to a cabbage leaf and partially covered by many small, white objects, usually considered eggs by those who do not know. As a matter of fact, these are the cocoons of the tiny para- sites that have lived within the body of the caterpillar and killed it. When the parasites are full-grown they leave the caterpillar and spin their small white cocoons on the outside, from which the small, dark-colored, wasp- like parasites emerge in a few days ready to parasitize other " cabbage ; Whenever a lot of these white cocoons are seen about a green caterpillar they should not be destroyed, but should be allowed to remain undisturbed so that the parasites may emerge to work on other " ; Methods of control.— This cabbage pest is best controlled by spraying the plants with one of the arsenicals, paris green or arsenate of lead. There is no danger in spraying cabbages with a poison up to the time they are half-grown, and even later. A cabbage is only a gigantic bud and grows from the inside outward as does any other bud. The outside leaves never fold up about the head, hence there is little danger of enclosing the poison within the cabbage. If paris green is used it should be applied at the rate of i pound to 150 gallons of water, or sifted on dry, in the latter case being thoroughly mixed with flour at the rate of i pound to 2 5 pounds of flour. This should be applied in the morning while the dew is yet on the cabbage leaves. Arsenate of lead may be applied at the rate of 2^ pounds to 50 gallons of water. The first applications of poison should be made when the " worms &
