In this way the beaver-dams are capable of resisting immense quantities of water which in its impetuous rush would carry away the ordinar

propagating the most erroneous ideas about the nature and works of these sea-builders. Montgomery, in his Pelican Island, makes statements that are shocking to an intelligent thinker, and which no scientist can excuse on the ground of poetical license. "The poetry of this excellent author," says Dana, "is good, but the facts nearly all errors-if literature allows of such an incongruity." Think of coral-animals as being referred to as shapeless worms that "writhe and shrink their tortuous bodies to grotesque dimensions"! These deep-sea builders manufact

Keeling or Cocos Atoll, of the Indian Ocean, is 9? miles in its greatest width; Bow Island is 30 miles in length, and 6 miles wide; while in the Maldive Archipelago one island measures 88 geographical miles in length, and in some places is 20 miles wide. When one beholds a large coral ring, covered with rich soil and tropical vegetation, and "protecting a quiet lake-haven from the restless ocean without, it is little to be wondered at that the earlier voyagers recorded their surpr
