Someone at the Ledge House heard Dot, and gave a low whistle and a quick command. Then there was a dashing rush through the bushes, that sounded as if a dog were chasing a cat. A few minutes later Dot's voice again called in the dark--this time, not in anguish of heart, but very cosily and gently. "Pete-weet?" she whispered; and four precious little babies murmured, "Peep," as they snuggled close to the spotted breast of their mother. So it happened that two sons and two daughters of Peter Piper, Junior, played and picnicked and bathed by the river. The one who had first pipped his eggshell was named Peter the Third, for his father and his grandfather, and a finer young sandpiper never shook the fluff of down from his head or the fringe from his tail, when his real feathers pushed into their places. What his brother and sisters were named, I never knew; and it didn't matter much, for their mother called them all "Pete." [Illustration: _Dallying happily along the river-edge._] Peter the Third and the others grew up as Pan and Peter and Sandy had grown, dallying happily along the river-edge, and as happily accepting the guidance of their mother, who made her slow flight from Faraway Island every now and then, usually so low that her spotted breast was reflected in the clear water as she came, the white markings in her wings showing above and below. Of course, as soon as the season came for their migration journey, the four of them started cheerfully off with Peter and Dot, for a leisurely little flight to Brazil and back--to fill the days, as it were, with pleasant wanderings, from the time the hummingbird fed at the feast of the cardinal flower in late summer, until he should be hovering over the columbine in the spring. IV GAVIA OF IMMER LAKE Once upon a time, it was four millions of years ago. There were no people then all the way from Florida to Alaska. There was, indeed, in all this distance, no land to walk upon, except islands in the west where the Rocky Mountains are now. That is the only place where the country that is now the United States of America stuck up out of the water. Everywhere else were the waves of the sea. There were no people, even on the Rocky Mountain Islands. None at all. No, the creatures that visited those island shores in those old days were not people, but birds. Nearly as large as men they were, and they had teeth on their long slender jaws, and they had no wings. They came to the islands, perhaps, only at nesting-time; for their legs and feet were fitted for swimming and not walking, and they lived upon fish in the sea. So they dwelt, with no man to see them, on the water that stretched from sea to sea; and what their voices were like, no man knows.
