How to Kill Bed Bugs.

Take of wormwood and rue a handful of each, mix them with common oil, also enough water, so that both water and oil will cover the herbs; after this boil the mass so long until all the water evaporates, whereupon squeeze the herbs in a press to obtain all the oil possible, and add a like quantity of mutton tallow; with this saturate the bedsteads, and the bugs will die.
