"While they were thus pleasantly occupied, the Little Villager and his companion had an idea. It was not a very usual thing with them, and they hastened to act upon it lest it should get away. They proceeded to block up their entrance tunnel about three feet from the door. They packed the earth hard, and made a good job of it, and flattered themselves that their guests would not get in in a hurry, even if they were pretty good burrowers themselves. Then at the extreme opposite corner of their central chamber they tunneled a new passageway, which brought them out quite on the other side of the hillock. This done, they felt very pleased with themselves, and settled down for a well-earned sleep, curled up in a furry ball together.

"At daybreak the owls came home. Confidently they ducked their big, round heads and dived down the old entrance, only to be brought up with a bump when they had gone about three feet. Out they came in a rage, fluffing their feathers and snapping their beaks, and stood on each side of the hole to talk the affair over. First, one and then the other reentered to investigate. They found it quite inexplicable. They felt sure this was the way they had previously entered—so sure, in fact, that again and again they tried it, only growing more and more puzzled and indignant with each attempt. Finally they came to the conclusion that they must have made some mistake. They scuttled solemnly round the hillock, and came upon the new entrance. Ah, of course, they had been mistaken. Their indignation vanished. They scurried in cheerfully, one hard upon the other's tail, and took up their place in their adopted corner. The Little Villager and his mate opened disgusted eyes upon them for a second, then went to sleep again, relinquishing all thought of further protest.

"After this, for a time, there was perfect peace in the house, the peace of mutual aversion. Hosts and guests ignored each other scrupulously. But after a while a family was born to the Little Villager, a litter of absurd, blind, tiny whimperers, all heads and hungry mouths. The two owls were immensely interested at once, but their efforts to show their interest were met by such an astonishing display of ferocity on the part of both the Little Villager and his mate that they discreetly withdrew their advances and once more kept strictly to themselves. They knew their business, these owls; and they knew they would lose nothing in the long run by a little temporary forbearance. They were well aware, from past experience with prairie dogs, that the vigilance of the happy parents would relax in course of time, and that all the while the little ones, growing larger and plumper every day, would be getting better worth the interest of an appreciative owl.

"The event proved they were right. As the days went by, and the young ones grew lively and independent, the Little Villager and his mate grew less and less anxious about them. Their soft eyes now wide open, they would leave the nest and wander about the burrow, in spite of all that their mother or their father (whichever happened to be in charge at the time) could do to prevent them. There were so many of them, moreover, that it was quite impossible to keep an eye on them all at once.

"Late one afternoon, in that debatable time when the owls in their corner were just beginning to wake up, two of the youngsters ran over quite near them. The temptation was irresistible. There was a light pounce, a light squeak instantly strangled, and one of the youngsters, badly frightened, ran back to the mother. The other remained, limp and motionless, in the owl's corner, with a set of steel-like talons clutching it.

"The mother started to the rescue boldly. But the moment she left the rest of the litter the second owl hopped over toward them. She paused in an agony of irresolution. Then she turned and scurried back. She could not sacrifice all for the sake of one. But as she gathered the survivors to her she barked and chattered furious defiance at the murderer. Her clatter brought down the Little Villager himself, and together they hurled all the insults they could think of at the owl, who, however, calmly turned his feathery back upon them and proceeded to devour his easy prey.

"For some days there was renewed vigilance, and the little ones kept close to their parents' side. But the memory of a prairie dog, especially of a young prairie dog, is distinctly short. Soon there was more wandering from the nest, and then a lot of childish racing about the floor of the burrow. Again a youngster went too near the owls' corner and remained there. This time there was no fuss about it, because the slaughter was accomplished quite silently, and the mother did not happen to see. After this there would never be more than two or three days go by without the sudden disappearance of one or another of the litter, which, after all, kept the burrow from becoming too crowded. The youngsters were getting so big by now that their parents began to lose all interest in them. It became time for them to be weaned. But as the interest of the owls had been increasing as that of the parents diminished, it happened by this time that there was not one left to wean. So the duty of the furry little mother, with her silly nose and her big, childish eyes, was singularly simplified. It was no use making more trouble with her unfriendly guests over a matter that was now past remedy. So all was overlooked, and the burrow settled down once more to the harmony of mutual aversion."

Uncle Andy stopped and proceeded to refill his pipe, waiting for the Child's verdict. The Child's face wore the grieved look of one who has had an illusion shattered.

"I shan't ever believe a word Bill tells me again," said he, with injured decision.

"Oh," said Uncle Andy, "you mustn't go so far as that. Bill tells lots of interesting things that are true enough as far as they go. You must learn to discriminate."
