If he answer right, let him retain his place; if not, let the first boy that answers the question correctly, have precedence. NOTE.-I begin at the bottom of the page, because there the numbers will form more difficult questions than those at the top, and generally the best scholars are near the head of the class. I do this to encourage those toward the foot of the class, who are not so forward as others: For if a boy can answer and say, 5 and 3 make 8, he will be better pleased than to answer with a negative shake of the head. This partiality, however, is not allowable when striving for a prize. END OF PART THIRD. INTRODUCTION TO ARITHMETIC, PART IV. CONTAINING, COMPOUND MULTIPLICATION. COMPOUND MULTIPLICATION.
