The worst of these superstitions is that they are easy to make and hard to destroy. A single run of luck has made the fortune of many a charm and many idols. I doubt if even a single run of luck be necessary. I am sure that if an elder boy said that 'the pretty fish was lucky--of course it was,' all the lesser boys would believe it, and in a week it would be an accepted idol. And I suspect the Nestor of a savage tribe--the aged repository of guiding experience--would have an equal power of creating superstitions. But if once created they are most difficult to eradicate. If any one said that the amulet was of certain efficacy--that it always acted whenever it was applied--it would of course be very easy to disprove; but no one ever said that the 'pretty fish' always brought luck; it was only said that it did so on the whole, and that if you had it you were more likely to be lucky than if you were without it. But it requires a long table of statistics of the results of games to disprove this thoroughly; and by the time people can make tables they are already above such beliefs, and do not need to have them disproved. Nor in many cases where omens or amulets are used would such tables be easy to make, for the data could not be found; and a rash attempt to subdue the superstition by a striking instance may easily end in confirming it. Francis Newman, in the remarkable narrative of his experience as a missionary in Asia, gives a curious example of this. As he was setting out on a distant and somewhat hazardous expedition, his native servants tied round the neck of the mule a small bag supposed to be of preventive and mystic virtue. As the place was crowded and a whole townspeople looking on, Mr. Newman thought that he would take an opportunity of disproving the superstition. So he made a long speech of explanation in his best Arabic, and cut off the bag, to the horror of all about him. But as ill-fortune would have it, the mule had not got thirty yards up the street before she put her foot into a hole and broke her leg; upon which all the natives were confirmed in their former faith in the power of the bag, and said, 'You see now what happens to unbelievers.'
