It would be a curious thing, if they could be traced out, to ascertain the origin of half the quaint old sayings and maxims that have come down to the present time from unknown generations. Who, for example, was “§Dick§,” who had the odd-looking “hat-band,” and who has so long been the synonym or representative of oddly-acting people? Who knows any thing authentic of the leanness of “Job’s turkey,” who has so many followers in the ranks of humanity? Scores of other sayings there are, concerning which similar questions might be asked. Who ever knew, until comparatively late years, what was the origin of the cautionary saying, “Mind your P’s and Q’s”? A modern antiquarian, however, has put the world right in relation to _that_ saying. In ale-houses, in the olden time, when chalk “scores” were marked upon the wall, or behind the door of the tap-room, it was customary to put the initials “P” and “Q” at the head of every man’s account, to show the number of “pints” and “quarts” for which he was in arrears; and we may presume many a friendly rustic to have tapped his neighbor on the shoulder, when he was indulging too freely in his potations, and to have exclaimed, as he pointed to the chalk-score, “Mind your P’s and Q’s, man! mind your P’s and Q’s!” The writer from whom we glean this information mentions an amusing anecdote in connection with it, which had its origin in London, at the time a “Learned Pig” was attracting the attention of half the town. A theatrical wag, who attended the porcine performances, maliciously set before the four-legged actor some _peas_,—a temptation which the animal could not resist, and which immediately occasioned him to lose the “cue” given him by the showman. The pig-exhibitor remonstrated with the author of the mischief on the unfairness of what he had done; to which he replied, “I only wanted to ascertain whether the pig knew his ‘peas’ from his ‘cues!’” ALL FOOLS’ DAY.
