For example, John and I sometimes take our books, and sit down on the rocks in the wood, under the thick trees, and read stories. And then Carlo will lie down at our feet, and go to sleep; for he cannot understand the nice stories which the other two friends enjoy so much.
But wait till we go into the swamps after berries, or into the wood-borders after hazel-nuts. Then Carlo is wide awake, you may be sure. If he sees a snake, what a noise he makes! We can always tell by the tone of his bark when he has found a snake.
And, when John climbs a tree after nuts, how anxiously Carlo will stand underneath and watch him, so afraid is he that the little boy will get a fall! And how the good dog will jump and show his pleasure when he sees John once more safe on the firm ground!
