QUOTE : Just beyond the opening the cave was higher, and as the boat floated into the dim interior they found themselves on quite an extensive branch of the sea. For a time neither of them spoke and only the soft lapping of the water against the sides of the boat was heard. A beautiful sight met the eyes of the two adventurers and held them dumb with wonder and delight. It was not dark in this vast cave, yet the light seemed to come from underneath the water, which all around them glowed with an exquisite sapphire color. Where the little waves crept up the sides of the rocks they shone like brilliant jewels, and every drop of spray seemed a gem fit to deck a queen.
