It seizes eagerly on all the food placed before it, and rapidly digests every acquisition. The condition of a mind with every appliance for improvement at hand, is not unlike that of a person with every variety and quality of food set before him for the gratification of a bodily appetite. Repletion, satiety, and indigestion, follow in one case precisely as in the other. Many of our modern students are crammed and gorged with study. The mental appetite is over-indulged; and an attempt to master too much is doubtless the besetting literary sin of the present day. The cases of mental dyspepsia are as common as those of the body. Sound scholarship consists not so much in the quantity of material consumed, as in the quantity properly prepared for intellectual nurture. A man may possess a fund of encyclopedic knowledge, and yet his mental powers may be weakened by the very process of grasping so many details. He may be good authority to appeal to, but will hardly prove a sound thinker or a good logician. "Not many, but good, books," was the golden advice of a wise man on the formation of a library. Self-made men, like Mr. Ballou, are apt to make judicious selections in culling the great field of knowledge, while those who pass through a regular, systematic, academic training, are often forced to fill their minds with a mass of matter for which they have no use, and to waste much time in questionable acquirements, simply because in so doing they comply with the requisitions of a prescribed formula. It was customary for the young men of all classes in those days to pursue athletic exercises, such as pitching the bar, leaping, wrestling, and the like, these being regarded as the surest tests of bodily strength. Possessing a powerful and active frame, he was ever the victor in those sports; and from his marked success among his comrades in this respect, and his fair and impartial disposition, he was universally the umpire in all disputes growing out of these and like contests for superiority that arose between one and another. In the matter of his physical strength, particularly when young, he ever cherished, a laudable degree of pride, and delighted in accomplishing a large amount of work within the hours devoted to labor. In this connection, Mr. Ballou says:--"I have the comfort, even in my old age, of remembering that I was deemed in our family circle to be a good child, and marked for giving evidence of being less averse to necessary labor than others. Though this contributed somewhat to make me proud, and to think well of myself, in other respects it was of some advantage to me to be held in esteem by my mates, who ever showed that they had a peculiar regard for me."
