COCK CHAFFERS. This species of the beetle, sometimes called the May bug, is a formidable enemy to the husbandman, and has been found to swarm in such numbers, as to devour every kind of vegetable production. The insect is first generated in the earth, from the eggs deposited by the fly in its perfect state. In about three months, the insects contained in these eggs break the shell, and crawl forth in the shape of a grub or maggot, which feeds upon the roots of vegetables, and continues in this state of secret annoyance for more than three years, gradually growing to the size of an acorn. It is the thick white maggot with a red head, so frequently found in turning up the soil. At the end of the fourth year, they emerge from the earth, and may be seen in great numbers in the mild evenings of May. The willow seems to be their favourite food; on this they hang in clusters, and seldom quit it till they have completely devoured its foliage. The most effectual way to destroy them, is to beat them off with poles, and then to collect and burn them. The smoke of burning heath, fern, or other weeds, will prevent their incursions in gardens, or expel them if they have entered. COCK ROACHES. These insects, consisting of various species, penetrate into chests and drawers, and do considerable injury to linen, books, and other articles. They seldom appear till night, when they infest beds, and bite very severely, leaving an unpleasant smell. The best remedy is to fill an earthen dish with small beer, sweetened with coarse sugar, and set in the place infested. Lay a board against the pan, to form a kind of ladder, and the insects will ascend and fall into the liquor. COCKLE KETCHUP. Open the cockles, scald them in their own liquor, and add a little water, if there be not enough; but it is better to have a sufficient quantity of cockles, than to dilute it with water. Strain the liquor through a cloth, and season it with savoury spices. If for brown sauce, add port, anchovies, and garlic: a bit of burnt sugar will heighten the colouring. If for white sauce, omit these, and put in a glass of sherry, some lemon juice and peel, mace, nutmeg, and white pepper.
