A farmer had a yearling that sucked the cows. To prevent this, he put on the yearling a muzzle set full of sharpened nails. These of course pricked the cows, and they would not stand to be drained of their milk. The next day the farmer saw the yearling rubbing the nails against a rock in order, as he thought, to dull them so they would not prick the cows! How much easier to believe that the beast was simply trying to get rid of the awkward incumbrance upon its nose. What can a calf or a cow know about sharpened nails, and the use of a rock to dull them? This is a kind of outside knowledge--outside of their needs and experiences--that they could not possess. An Arizona friend of mine lately told me this interesting incident about the gophers that infested his cabin when he was a miner. The gophers ate up his bread. He could not hide it from them or put it beyond their reach. Finally, he bethought him to stick his loaf on the end of a long iron poker that he had, and then stand up the poker in the middle of his floor. Still, when he came back to his cabin, he would find his loaf eaten full of holes. One day, having nothing to do, he concluded to watch and see how the gophers reached the bread, and this was what he saw: The animals climbed up the side of his log cabin, ran along one of the logs to a point opposite the bread, and then sprang out sidewise toward the loaf, which each one struck, but upon which only one seemed able to effect a lodgment. Then this one would cling to the loaf and act as a stop to his fellows when they tried a second time, his body affording them the barrier they required. My friend felt sure that this leader deliberately and consciously aided the others in securing a footing on the loaf. But I read the incident differently. This successful jumper aided his fellows without designing it. The exigencies of the situation compelled him to the course he pursued. Having effected a lodgment upon the impaled loaf, he would of course cling to it when the others jumped so as not to be dislodged, thereby, willy nilly, helping them to secure a foothold. The coöperation was inevitable, and not the result of design. The power to see straight is the rarest of gifts; to see no more and no less than is actually before you; to be able to detach yourself and see the thing as it actually is, uncolored or unmodified by your own sentiments or prepossessions. In short, to see with your reason as well as with your perceptions, that is to be an observer and to read the book of nature aright. XIV GATHERED BY THE WAY I. THE TRAINING OF WILD ANIMALS
