I will specify only one more of my collection, of yet another kind. This is a printed circular appealing to a class of fools, if possible, even shallower, sillier, and more credulous than any I have named yet. It is headed "The Gypsies' Seven Secret Charms." These charms consist of a kind of hellbroth or decoction. You are to wet the hands and the forehead with them, and this is to render you able to tell what any person is thinking of; upon taking any one by the hand, you will be able to entirely control the mind and will of such person (it is unnecessary to specify the purpose intended to be believed possible). These charms are also to enable you to buy lucky lottery-tickets, discover things lost or hid, dream correctly of the future, increase the intellectual faculties, secure the affections of the other sex, etc. These precious conceits are set forth in a ridiculous hodge-podge of statements. The "charms," it says, were used by the "Anted_e_luvians;" were the secret of the Egyptian enchanters and of Moses, too; of the Pythoness and the heathen conjurors and humbugs generally; and (which will be news to the geographers of to-day) "are used by the Psyli (the swindler mis-spells again) of South America to charm Beasts, Birds, and Serpents." The way to control the mind, he says, was discovered by a French traveler named Tunear. This Frenchman is perhaps a relative of the equally celebrated Russian traveller, Toofaroff. But here is the point, after all. You send the money, we will say, for one of these charms--for they are for sale separately. You receive in return a second circular, saying that they work a great deal better all together, and so the man will send you all of them when you send the rest of the money. Send it, if you choose! Now, how is it possible for people to be living among us here, who are fooled by such wretched balderdash as this? There are such, however, and a great many of them. I do not imagine that there are many of these addlepates among my readers; but there is no harm in giving once more a very plain and easy direction which may possibly save somebody some money and some mortification. Be content with what you can honestly earn. Know whom you deal with. Do not try to get money without giving fair value for it. And pay out no money on strangers' promises, whether by word of mouth, written letters, advertisements, or printed circulars. CHAPTER XXIII.
