One of the, to him, richest jokes, and one which he always enjoyed telling, related to a country singing school which was located in the neighborhood of Pierceton, in which reading (the alphabet, at least), spelling, geography, arithmetic, rules of grammar, and so forth, were still taught by a process of singing. The method adopted in this form of education was to have the scholar memorize all knowledge by singing it. Thus in the case of geography the students would sing the name of the country, then its mountains, then the highest peaks, cities, rivers, principal points of interest, and so on, until all information about that particular country had been duly memorized in song or rhyme. Occasionally they would have a school-day on which the local dignitaries would be invited, and on a number of these occasions the doctor was, for amusement's sake merely, a grave and reverent listener. On one occasion, however, he was merely passing the school, when hearing "Africa-a, Africa-a, mountains of the moo-oo-oon" drawled out of the windows, he decided to stop in and listen a while. Having tethered his horse outside he knocked at the door and was received by the little English singing teacher who, after showing him to a seat, immediately called upon the class for an exhibition of their finest wisdom. When they had finished this the teacher turned to him and inquired if there was anything he would especially like them to sing. "No," said the doctor gravely, and no doubt with an amused twinkle in his eye, "I had thought of asking you to sing the Rocky Mountains, but as the mountains are so high, and the amount of time I have so limited, I have decided that perhaps it will be asking too much." "Oh, not at all, not at all" airily replied the teacher, and turning to his class, he exclaimed with a very superior smile: "Now, ladies and gentlemen, 'ere is a scientific gentleman who thinks it is 'arder to sing of _'igh_ mountings than it is to sing of _low_ mountings," and forthwith the class began to demonstrate that in respect to vocalization there was no difference at all.
