A quite common superstitious practice, in order to rid a house of Cockroaches, is in vogue in our country at the present time. It is no other than to address these pests a written letter containing the following words, or to this effect : “0, Roaches, you have troubled me long enough, go now and trouble my neighbors.” This letter must be put where they most swarm, after sealing and going through with the other customary forms of letter writing. It is well, too, to write legibly and punctuate according to rule.
