You know why it is said that "the cuckoo builds no nest at all," don't you? May has a verse which calls him "a most conceited bird," because from the time when he comes back from Africa we hear him constantly calling his own name, 'coo-coo, coo-coo!' Still, I don't think the cuckoo should be called "conceited" when it is we who have given it its name from the call which is natural to it; but it is a most unfaithful bird, and leaves its little ones to be brought up by others, not taking the trouble to build a cradle for them, nor will the mother sit upon her eggs. I used to think the reason why we saw so few cuckoos was because this bird laid only one egg; but I have read that she lays eight, each one in the nest of some bird much smaller than herself. The cuckoo is grey, and about the size of a blackbird; but her eggs are small, not bigger than a hedge-sparrow's or a lark's. She lays her egg on the ground, and then lifts it with her bill into the nest which she has chosen. The stranger bird is hatched first, and always behaves as if the whole nest belonged to him. He grows bigger and bigger, until at last he throws the little sparrows over the side of the nest to make room for himself. When the "woolly bears "--the caterpillars on which they feed--are all gone the cuckoos fly off to find them in South Africa. How different from this bird is the faithful dove, who would not desert her little one, even to save her own life! I must tell you the story of the particular dove of which I am thinking. When the famous city of Pompeii--which had lain for eighteen hundred years buried beneath the ashes and mud which fell upon it during a terrible eruption of Mount Vesuvius--was brought to light again, as the workmen were digging among the ruins of what had been a beautiful house, in a niche overlooking the garden they found the skeleton of a dove. They were not surprised that, as the sky grew darker and darker upon that dreadful day, and the soft, choking shower of ashes fell more thickly, many of those who ran for their lives should have lost their way in the darkness, and fallen to rise no mare. The skeletons of men and women had been found, just as they had fallen while trying to escape; but this dove, with her swift wings, why did she not flee away? Ah, as they lifted her from her nest the secret was revealed: beneath her lay the egg which the timid, gentle creature, so brave in her love and faithfulness, would not leave.
