D._ For the stings of insects, wasps, hornets, bees, etc. Apply to the place soda, hartshorn, or arnica. RATS.

All fat and grease from the kitchen should be carefully saved, and should be made into soap before accumulating and becoming offensive. Boil for six hours ten gallons of lye made of green wood ashes. Then add eight or ten pounds of grease, and continue to boil it. If thick or ropy, add more lye till the grease is absorbed. This is ascertained by dropping a spoonful in a glass of water, and if grease remains it will show on the water.
