118 LUCY AMONG THE MOUNTAINS. main stream, Lucy observed a large, flat surface of rock, of a blue color, which seemed to be quite level and smooth. There was a bird upon it, hopping about. The main current was running very swiftly along that end of it which was to- wards the stream, and there was a little water, too, on each side of it; so that it was a sort of an island. “J wish I could go down on that great blue stone,” said Lucy. “Tt is very easy to get there,” said the gurl. “Tve been on it a hundred times.” “TI mean to go and ask Comfort to let me go down and get on it,” said Lucy. So Lucy went into the store, but in a moment came out again. The girl asked what Comfort said. “She says f must not go now,” said Lucy, ‘but that, when she has done her shopping, she will go with me.” “Js that the mill-pond up there?” said Lucy, pointing to the sheet of water above the dam. “ Yes,” said the girl. “ What a pretty little island!” said Lucy. While Lucy was locking at the island, she happened to observe something upon the water, very far off, and she did not know what it was.
