1040. _For Destroying Bugs and Worms in Wood._--An eminent physician has discovered that by rubbing wood with a solution of vitriol, insects and bugs are prevented from harboring therein. When the strength of this remedy is required to be increased, there need only be boiled some coloquintida apples in water, in which, afterwards, vitriol is dissolved, and the bedstead, with the wood about them, and the wainscoting, being anointed with the liquor, will be ever after clear of worms or bugs. The wall may be likewise rubbed with the composition, and some of it may be dropped into the holes where these insects are suspected to be harbored. As to the walls, they require only to be washed over with the vitriol water. 1041. _To Destroy Insects on Wall Fruit Trees._--Take an old tin watering-pan, or any similar vessel, and make a charcoal fire in it; add a tube or pipe, made of either tin, leather, or stiff paper, to the spout, which may be of any sufficient length; then strew some brimstone, tobacco-dust, fine shreds of leather, &c., upon the fire, in the pan, and cover the top; having a pair of bellows ready, hold the wind-flap over the tube or pipe to receive the smoke, which it will do very effectually when you use the bellows. By this means the suffocating vapor may be directed through the bellows to any part of the tree with the greatest ease and facility, and the tree soon cleared of all vermin. 1042. _To Destroy the Insect which attacks the Apple Tree, commonly called the White Blight, or American Blight._--To a strong decoction of the digitalis or foxglove, add a sufficient quantity of fresh cow-dung, to give it such a consistence as may enable you to apply it with a painters' brush to those parts of the bark of the tree, which afford a harbor for this destructive insect. The insect is generally destroyed by the first application, though in some instances it may be necessary to repeat it. It has been remarked that the insect never returns in future years to those parts of the tree which have been thus treated.
