DAGELET, the name given by La Peronse, the celebrated though unfortunate navigator, to an island on the coast of Corea (see COREA Encycl.), which he discovered in the year 1787. It is little more than three leagues in circumference; and our author almost made its circuit at the distance of a mile without finding bottom. This small spot is very steep, but covered with the finest trees from the sea-shore to the summit. A rampart of bare rock, like a wall, encircles the whole outline of it, with the exception of seven little sandy creeks, where it is possible to land. In these creeks the Frenchmen saw upon the stocks some boats of a construction altogether Chinese; but the sight of their ships frightened the workmen, who fled from their dock. dock-yard into the wood, which was not more than fifty paces distant. As a few huts were seen, but neither villages nor cultivation, La Perouse concluded that the island is without inhabitants, and that the men whom he saw at work were Corean carpenters, who during the summer months go with provision to Dagelet for the purpose of building boats, which they sell upon the continent. He places the north east point of this island in N. Lat. 37° 25' and E. Long. 129° 2' from Paris.
