Whistling to keep one’s courage up, or for a wind, are rather in the nature of an invocation to some occult power than a sign. Sailors, it is well known, have a superstitious fear of whistling at sea, believing it will bring on a storm. Yawning is said to be catching. Well, if it is not catching, it comes so near to being so, that most persons accept it as a fact; and laugh as we may, daily experience goes to confirm it as such, and must continue to do so until some more satisfactory explanation is found than we yet know of. [Illustration] V CHARMS TO GOOD LUCK “The nights are wholesome; then no planets strike, No fairy takes, nor witch hath power to charm.” Of the things closely associated in the popular mind with good or bad luck, what in short one may or may not do to obtain the favors or turn aside the frowns of fortune, the list is a long one. We say “God bless me!” when we sneeze, as an invocation to good luck. Then, for instance, it is considered lucky to find a cast-off horseshoe, or a four-leaved clover, or to see the new moon over the right shoulder, or to have a black cat in the house, especially one that comes to you of its own accord. Then there also is the lucky pocket-piece, which the owner will seldom part with, although I once heard a man loudly lamenting that he had “sold his luck” by doing so. There also is the lucky-bone of a haddock,[8] the wishing-bone of a chicken, the lucky base-ball bat, and, what is still more strange, the lucky spider, if one happens to be found on one’s clothes,--though this will hardly prevent, we imagine, all womankind from screaming out to the nearest person to come and brush off the hateful little creature. Many will not kill a spider on account of this belief, which is supposed to be derived from the romantic story of King Robert Bruce and the spider. The familiar saying, “There’s luck in odd numbers,” lingers in song and story. Does not Rory O’More say so? Odd numbers or combinations of odd numbers are almost invariably chosen in buying lottery tickets. Moreover, they have received the highest official sanction for a very long time. In the “Art of Navigation,” printed in the year 1705, the following rule is laid down for firing salutes by ships of the royal navy: “to salute with an odd number of guns, the which are to be answered with fit correspondency. And the number of odd guns is so punctually observed, that whenever they are given _even_ ’tis received for an infallible sign that either the captain or some noted officer is dead in the voyage.”
