According to a Florida paper a remarkable geological discovery has been made there. The _Galena Advocate_ says: “As P. M. Oliver, in company with a lot of friends, was chasing a fox through his field near Payne’s prairie Saturday night last his horse ran into a sink and in getting the animal out Sunday morning attention was attracted to the numerous curious petrological formations on the sides of the sink. Further examination Monday disclosed immense beds of the petrified bones of the now extinct dinotherium giganteum, icthyosaurus, glyptodon, cuvieri, plesiosaurus, and peterodactyl. This is probably the richest find in the world and was altogether accidental.” TUNNELLING FOR WATER. FOLKS OUT IN IDAHO WHO RUN THEIR WELLS INTO A SIDE HILL. The citizens of Sweet, Canyon County, Idaho, have a novel way of obtaining water for domestic and irrigation purposes. The water is dug out of the hillside, with wells run like tunnels, and not down into the earth as ordinary wells are dug. East of the town, there is a bluff out of which sparkling mountain water can be procured almost anywhere by merely running a tunnel in from twenty to forty feet. At one point in town, a stream sufficient to irrigate a fine orchard and garden, besides an ample supply for domestic use and for watering all the teams that pass that way, comes pouring out of the 40-foot tunnel. Neither the spring freshets nor the summer drouths affect its flow. DOMINICA’S BOILING LAKE. A NATURAL CURIOSITY THAT WAS NOT DISCOVERED TILL 1875. Mr. Sterns-Fadelle of Dominica has just published a little book giving some interesting information recently obtained about a curious natural phenomenon in Dominica, one of the Lesser Antilles. This island is only 291 square miles in area. It was colonized by the Spaniards in the seventeenth century and peopled later by French emigrants, who controlled the island uninterruptedly until the eighteenth century, and its resources have since been exploited by English and French; and yet its natural curiosity in the northern part of the island had never been seen or heard of until twenty-eight years ago. This can be explained only by the fact that the neighborhood of the boiling Lake of Dominica is difficult of access. The lake was discovered by an Englishman, Dr. Nichols, who organized an expedition to explore the unknown part of the island. One day his little party were clambering up a mountain. They suddenly came upon evidences of sulphur, and a moment later stood looking down into a crater which was filled with boiling water. Stifling vapors rose from the agitated surface, rumblings of thunder came from the subterranean regions, and near the center of the little lake, where the water was most violently disturbed, the furious boiling lifted the surface ten or twelve feet above the general level. The lake was constantly fed by several small brooks that poured from the heights above the crater.
