=White Vitriol=: Sulphate of zinc, a powerful astringent germicide, needs care in handling. Dissolve it, four ounces to the half gallon of water, strain, and put into clean bottles. Keep dark, corked tightly. Use to clean and disinfect sores from frost bite or indolent ulcers. Dilute with five times as much tepid rain water. Use on the combs of poultry when raw from frost, also for scaly leg and the ail known as “bumble-foot.” =Bichloride of Mercury=: The king among disinfectants, also one of the deadliest among poisons. Dissolve in boiling rain water, four ounces to the gallon. Let stand; it dissolves slowly. Keep in glass, tightly corked, plainly labeled “poison.” Dilute one-half for use in the sick room. But put on full strength when fighting bed bugs. =Bordeaux Mixture=: Staple for spraying against molds, etc. One pound blue vitriol dissolved in five gallons rain water and added to one pound powdered unslaked lime mixed to a cream with rain water. Stir well, and strain before spraying. Dilute one-half to three-fourths; if too strong it scorches vegetation. =Kerosene Emulsion=: Stir hard together in an earthen vessel a quart of buttermilk and half a gallon kerosene. Stir with wood until thick and buttery. Use full strength to paint tree trunks and hard branches in winter, but dilute at least ten times for use on green things. Mix with warm water, twenty parts to one for spraying against plant lice. For fighting red spider stir a little sulphur into the emulsion before diluting. Spray late—as near night as possible. =Bisulphide of Lime=: Sure death to either animal or plant lice. Mix in equal quantity flowers of sulphur and powdered quicklime, cover two inches with boiling water, boil five hours, filling up and adding more water till there is three times the original quantity. Dilute the result, a brown smelly liquid, one hundred times for use either as wash or spray. =Against Garden Pests=: Mix any arsenical powder—London purple, Scheele’s green, or Paris green—with its own bulk of flour and twice its bulk of slaked lime, and dust upon plants while damp. Good for potato beetles, squash bugs, flea bugs, grasshoppers, cut worms, and cabbage worms. Use in a powder gun or tie in a thin bag, fasten it to a long pole and shake so as to coat plants evenly.
