A new and troublesome enemy to the cabbage tribe which has made its appearance within a few years, and spread rapidly over a large section of the country, is a green worm, Anthomia brassicÆ. This pest infests the cabbage tribe at all stages of its growth; it is believed to have been introduced into this country from Europe, by the way of Canada, where it was probably brought in a lot of cabbage. It is the caterpillar of a white butterfly with black spots on its wings. In Europe, this butterfly is preyed on by two or more parasites, which keep it somewhat in check; but its remarkably rapid increase in this country, causing a wail of lamentation to rise in a single season from the cabbage growers over areas of tens of thousands of square miles, proved that when it first appeared it had reached this country without its attendant parasites.

Besides this green worm, there are found in Europe four varieties of caterpillar variously marked, the caterpillars from all of which make great havoc among the cabbage tribe.

The most effective destroyer of this, and about every other insect pest, is what is known as the "Kerosene Emulsion." This is made by churning common kerosene with milk or soap until it is diffused through the liquid.

Take one quart of kerosene oil and pour it into a pint of hot water in which an ounce of common soap has been dissolved; churn this briskly while hot (a force pump is excellent for this), and, when well mixed, which will be in a few minutes, it will be of a creamy consistency; mix one quart to ten or twelve of cold water, and spray or sprinkle it over the plants with a force-pump syringe or a whisk broom.

Another remedy is pyrethrum. Use that which is fresh; either blowing it on in a dry state with a bellows, wherever the worm appears, or using it diluted, at the rate of a tablespoonful to two gallons of water; applying as with the kerosene emulsion. Mr. A. S. Fuller, who is good authority on garden matters, succeeds by applying tar-water. Place a couple of quarts of coal tar in a barrel and fill with water; let it stand forty-eight hours, then dip off, and apply with a watering-pot, or syringe.

Chickens allowed to run freely among the growing plants, the hen being confined in a movable coop, if once attracted to them will fatten on them. This remedy might answer very well for small plots. Large areas in cabbage, in proportion to their size are, as a rule, far less injured by insect enemies than small patches. The worm is of late years less troublesome in the North than formerly.
