1043. _For Destroying Caterpillars on Gooseberry Bushes._--Take one Scots pint (two English quarts) of tobacco liquor (which may be made, where it cannot be purchased, by infusing any kind of tobacco in water till all the strength be extracted) which the manufacturers of tobacco generally sell for destroying bugs, and mix them with about one ounce of alum; and when the alum is sufficiently dissolved, put this mixture into a plate, or other vessel, wide and long enough to admit of a brush, like a weaver's brush, being dipped into it; and as early in the season as you can perceive the leaves of the bushes to be in the least eaten, or the eggs upon the leaves (which generally happens about the end of May), and which will be found in great numbers on the veins of the leaves on their under side; you are then to take the preparation, or liquor, and after dipping the brush into it, and holding the brush towards the under side of the bush, which is to be raised and supported by the hands of another person; and by drawing your hand gently over the hairs of the brush, the above liquid is sprinkled, and falls in small drops on the leaves; the consequence of which is, if the eggs are there, they never come forward; and if they have already generated worms, in a minute or two after the liquor touches them, they either die or sicken, so as to fall off the bush; at least they do so upon giving it a little shake. If, upon their thus falling off, they shall not appear completely dead, the bush should be held up, and either a little boiling water from a watering-pot thrown over them, or a bruise given them by a spade or shovel; or the earth, where they lie, turned over with a hoe. This preparation does not in the least injure the bushes. 1044. _To Preserve Flowers, Leaves, and Fruit, from Caterpillars._--These depredators are destroyed by oils, which close the lateral pores by which they breathe. For this purpose it is advised, that on the approach of spring, a cloth, dipped in train oil, be laid on such parts of the tree in which there is the least appearance of them.
