At Mammoth Spring, Ark., and under the shadow of the Ozark Mountains, is the largest spring in the world. The water comes up in such a body that it forms a lake about the orifice. The output of the spring is 29,600,000 gallons daily. Records have been kept of it for ten years, and during that time the output has not varied 100 gallons a day nor the temperature a single degree. Winter and summer the spring remains at 59 degrees. The spring is evidently the outlet of some underground river. * * * * * The Poncho springs in Colorado are all on the side of a mountain, and hot and cold water flows from the ground in places not more than three inches apart. FRESH WATER FROM A SALT BAY. _From the Florida Times-Union and Citizen._ BELLEAIR, March 3.--The Eldridge spring is quite an attraction to the visitors; it furnishes drink water for the hotel. It is out in the bay, but is cemented up, so as to keep out the salt water, and throws up 100,000 gallons of water per day. * * * * * A species of eyeless fish has been found in a subterranean boiling spring discovered in a Nevada mine. * * * * * The motion of the earth around the sun is 68,305 miles an hour; over 1,000 miles a minute, or nineteen miles a second. A STRANGE POND. Hicks Pond, in Palmyra, Me., is a strange body of water. It is only twelve acres in area, but it is more than 100 feet in depth. It has no visible inlet, although a fair sized stream flows from it into Lake Sebasticook. The volume of its waters is not materially affected by either drouth or freshet, and the water is always cold.--_Philadelphia Ledger._ WONDERS BENEATH THE SURFACE. Workmen engaged in sinking an artesian well in Sandy Valley, near Niria, N. M., struck an open seam, from which a cold stream of air rushed with force enough to remove a 12-pound rock laid over the opening. The air was charged with millions of small yellow bugs, each having but two legs, no wings and a small red circle on his back. They lived but a few seconds after striking the warm outside air. Local scientists are puzzling over the question: How did they get so far down into the earth?--_St. Louis Republic._ FISH IN AN OLD WELL. Some queer fish were taken out of the recently reopened well on the United States fish station at San Marcos, Texas, says the Louisville _Courier-Journal_. There were several salamanders, varying in length from an inch and a half to four and a half inches. These creatures live on land or water, have human-looking faces, hands and feet, bulldog head, tail of an eel and body of fish. There were also large numbers of shrimps, resembling sea shrimps, only much smaller. It is an artesian well, and everybody wants to know where the creatures come from. * * * * *
