"Good-by, little brother!" called John after it. "I wish I could fly as you do and look down upon the kingdom of the forest! Then indeed I would learn all the secrets of our friends up in the treetops there, who hide their nests so selfishly. Oh, I should so love to see all the little baby birds! To be sure, some that I have seen in the ground-nests are ugly enough. Oh, the big mouths of them! Oh, the bald skins and prickly pin-feathers! Ha! ha!" John laughed so heartily that Brutus came running up to see what the joke was. "O Brutus!" cried John. "I think I know why the father and mother birds build their nests so high. They are ashamed to have any one see their funny little ones before they are quite dressed!" Brutus looked up in John's face and seemed to smile. The boy and the dog often had talks together in this wise. "I think I will ask them," said John. "Now, Brutus, lie still." He gave a peculiar whistle, waited a moment, and repeated it, twice, thrice. At the first call there was a fluttering in the branches overhead. At the second call one saw the silhouettes of tiny bodies dropping from branch to branch ever nearer to the boy below. At the third, there was a flutter, a rush of wings, and a flock of dear little birds came flying to John's shoulder, to his out-stretched arms, to his head; so that presently he looked like a green bush which they had chosen for their perch. John talked with them in his own way, with chirps and lisping of the lips, and they were no more afraid of him than of a good-natured tree. But after a while, a fly, which had been tickling Brutus's nose, grew so impertinent that the poor dog had to punish him with his paw. At the sudden movement the birds fluttered away, and John looked reproachfully at his friend. But when he saw the drop of blood on the dog's nose he forgave him. [Illustration: John talked with them.] "Poor Brutus!" he said. "You kept still as long as you could, I know. And indeed, it is time we were moving. Come, Brutus!" The pair continued their voyage of discovery. The woods are so full of thrilling stories for those who know how to read them! A field-mouse's nest in a tuft of grass; a beehive in a hollow tree; tracks of a wild boar in the muddy edge of the brook; a beautiful lizard changing color to match the leaves and moss over which it crept. John longed to carry this little brother home to join the circle of pets. But he knew it was kinder to leave him there, where perhaps he had a home and family. And oh, the flowers! So many kinds, so fragrant and so beautiful! John gathered a great armful to carry back to the Hermit. And so the minutes went; the shadows began to lengthen, and it was time to turn homeward.
