Many and various are the uses to which coal tar may be applied in the destruction of insect pests. Certainly much damage has been done by an indiscriminate use of the article, but if used properly and with judgment, it will be found of very great value. Many valuable powders may be made from it by combining it with other substances. The simplest and easiest powder made of it is to run a quantity into a pile of fine sand - sea, pit or drift, it does not matter which. In a very short time the sand will absorb all it will take without much stirring. It will then fall to pieces and may be kept in a vessel for years without losing its insecticide value. If this powder be used pretty freely over the floor of the poultry house, and shaken through their nests, no vermin of any kind will annoy them. It should be used pretty freely in summer, when insects breed so fast, especially around growing crops, which are subject to their depredations, but must not come in contact with the leaves of any plant.

It will drive away the squash-bug (Coreus tristes), and every other species of the natural order, Hymenoptera, with which we are acquainted, in double quick time.
