Everything that there was to know about a horse, confidently thought the little boy, this wonderful man knew. The very language that he used when talking about horses was a language full of strange, hard, words, the meaning of which was hidden from the childish worshiper of wisdom. Such words as "ringbone" and "spavin" and "heaves" and "stringhalt" and "pastern" and "stifle" and "wethers" and "girth" and "hock," to the boy, seemed to establish, beyond all question, the intellectual greatness of the one who used them just as words of many syllables sometimes fix for older children the position on the intellectual heights of those who use them. "Chiaroscuro," "cheiropterous," "eschatology," and the "unearned increment"—who, in the common, every day, grown up, world, would dare question the artistic, scientific, religious, or political, knowledge of one who could talk like that?
Nor did the intellectual strength of this wise one of the Yesterdays exhaust itself with the scientific knowledge of horses. He was equally at home in the co-ordinate sciences of cows and pigs and chickens. Again the boy stood in the cow shed laboratory and watched, with childish wonder, the demonstration of the master's superior wisdom as the white streams poured into the tinkling milk pail. How did he do it—wondered the boy—where did this wizard in overalls and hickory shirt and tattered straw hat acquire his marvelous scientific skill?
In the garden, the orchard, or the field, it was the same. No secret of nature was hidden from this learned one. He knew whether potatoes should be planted in the dark or light of the moon: whether next winter would be "close" or "open": whether the coming season would be "early" or "late": whether next summer would be "wet" or "dry." Always he could tell, days ahead, whether it would rain or if the weather would be fair. With a peach tree twig he could tell where to dig for water. By many signs he could say whether luck would be good or bad. Small wonder that the boy felt very ignorant, very humble, in the presence of this wise one!
Then, one day, the boy, to his amazement, learned that this wizard of the barnyard knew nothing at all about fairies. Common, every day, knowledge was this knowledge of fairies to the boy: but the wise one knew nothing about them. So dense was his ignorance that he even seemed to doubt and smiled an incredulous smile when the boy tried to enlighten him.
It was a great day in his Yesterdays when the boy discovered that the hired man did not know about fairies.
As the years passed and the time approached when the boy was to become a man, he learned the meaning of many words that were as strange to the intellectual hero of his childhood as the language of that companion of horses had once been strange to him. In time, much of the knowledge of that barnyard sage became, to the boy, even as the boy's knowledge of fairies had been to the man. Still—still—it was a great day in his Yesterdays when the boy discovered that the hired man did not know about fairies. Perhaps, though, it was just as well that the hired man did not know. If he had become too familiar with the fairies, his potatoes might not have been planted either in the light or the dark of the moon and the world's potatoes must be planted somehow.
Equally great in his special field of knowledge was the old, white haired, negro who lived in a tiny cabin just a little way over the hill. Strange and awful were the things that he knew about the fearsome, supernatural, creatures, that lived and moved in the unseen world. Of "hants" and "spirits" and "witches" and "hoodoos" he told the boy with such earnest confidence and so convincing a manner that to doubt was impossible. In the unknowable world, the old negro moved with authority unquestioned, with piety above criticism, with a religious zeal of such warmth that the boy was often moved by the old man's wisdom and goodness to go to him with offerings from mother's pantry.
And then, one day, the boy discovered that this wonderfully wise one could neither read nor write. Everybody that the boy knew, in the grown up world, could read and write. The boy himself could even read "cat" and "rat" and "dog." Vaguely the boy wondered, even then, if the old black saint's lack of those commonplace accomplishments accounted, in any way, for his marvelous knowledge of the unseen world.
And father—father—was the greatest, the wisest, and the best man that ever lived. The boy wondered, sometimes, why the Bible did not tell about his father. Surely, in all the world, there was no other man so good as he. And, as for wisdom! There was nothing—nothing—that father did not know! Always, when other men came to see them, there was talk of such strange things as "government" and "party" and "campaigns" and "senators" and "congressmen"—things that the boy did not in the least know about—but he knew that his father knew, which was quite enough, indeed, for a boy of his age to know.
The boy, in his Yesterdays, wondered greatly when he heard his father sometimes wish that he could be a boy again. To him, in the ignorance of his childhood, such a wish was very strange. Not until the boy had himself become a man and had learned to rightly value Ignorance did he understand his father's wish and in his heart repeat it.
