Dissolve the concentrated lye in the water, add the sugar and boil the solution, meanwhile gradually adding the arsenic. While still warm dip porous paper (cut into small squares) in the solution and dry them. For use place in plates or saucers partly filled with water where the flies can get at them.
Sticky Fly Paper.
| Rosin8 | ounces. |
| Lard or cotton-seed oil3 | ounces. |
Boil together, spread thinly on manilla paper, place another sheet on top, and when wanted pull them apart and it is ready for use. This is now usually preferred to the poison paper, as the flies are caught and held and do not die and drop into food, etc.
Mosquito and Fly Frightener.
| Petrolatum1 | ounce. |
| Paraffine 1/8 | ounce. |
| Oil pennyroyal 1/3 | ounce. |
| Oil of tar 2/3 | ounce. |
| Carbolic acid 2/3 | drachm. |
Melt the solid ingredients together, and when partly cooled add the other ingredients. This is an elegant preparation to rub on the hands and face where flies, mosquitos, gnats, etc., are troublesome.
Inks.
Late improvements in the manufacture of inks are due to the discovery and cheapening of substances which can be used in preparing them. While good common writing inks are quite easily procured in the market, still they can be manufactured much cheaper by the consumer; and then again there are a variety of special purposes which require inks that are not on sale, and formulas for making them are very valuable. In this collection we give approved and tested formulas for everything in the ink line.
