There is a lake of boiling water in the Island of Dominica, lying in the mountains behind Roseau, and in the valleys surrounding it are many solfataras, or volcanic sulphur vents. In fact, the boiling lake is little better than a crater filled with scalding water, constantly fed by mountain streams, and through which the pent-up gases find vent and are ejected. The temperature of the water on the margins of the lake ranges from 180° to 190° Fahrenheit; in the middle, exactly over the gas vents, it is believed to be about 300°. Where this active action takes place the water is said to rise two, three, or even four feet above the general surface level of the lake, the cone often dividing so that the orifices through which the gas escapes are legion in number. This violent disturbance over the gas jets causes a violent action over the whole surface of the lake, and, though the cones appear to be special vents, the sulphurous vapors rise with equal density over its entire surface. Contrary to what one would naturally suppose, there seems to be in no case violent action of the escaping gases, such as explosions or detonations. The water is of dark gray color, and having been boiled over and over for thousands of years, has become thick and slimy with sulphur. As the inlets to the lake are rapidly closing, it is believed that it will soon assume the character of a geyser or sulphurous crater.--_St. Louis Republic._ AN UNCANNY LAKE. There is in Missouri a lake, perched on the top of a mountain, its surface from 50 to 100 feet below the level of the earth surrounding it, fed by no surface streams, untouched by the wind, dead as the sea of Sodom. There is no point of equal altitude from which water could flow within hundreds of miles, and yet it has a periodical rise of 30 feet or over, which is in no way affected by the atmospheric conditions in the country adjacent. It may rain for weeks in Webster County, and the return of fair weather will find Devil’s Lake at its lowest point, while it may reach its highest point during a protracted drouth.--_St. Louis Globe-Democrat._ CURIOUS LAKE IN THE WEST INDIES. CHICAGO, Oct. 14.--_Editor of the Herald_:--In your very interesting “Missing Links” of to-day you mention the great sunken lake in the Cascade Mountains as the most deeply sunken lake in the world. This reminded me of a lake similar to this which I visited while traveling in the West Indies in 1891. This lake is situated in the island of St. Vincent on the highest peak of the Souffrière range of mountains, 4,500 feet above the level of the sea. It is one mile and a half down to the surface of the water and like the Cascade Lake the depth of the water is unknown. Soundings were taken many years ago by Lieutenant Smith, of the United States navy, but with no result. The lake is almost a complete circle and is about three or four miles in circumference.
