A Subterranean River in Colorado.
A dispatch of January 26 from Leadville, Col., says: “Yesterday after the men engaged in a drift of the La Plata mine had fired a round of holes they were astonished by hearing a noise resembling the rushing of a mighty river, and when the smoke cleared away they saw from where they stood a river running out of the drift. They barely had time to escape, ann in less than five hours the mine was flooded to within 270 feet of the surface. Four thousand feet of drift ore are submerged and thousands of feet of slopes are covered. Many think a lake was encountered, and that when the opening was made by the shots it burst through the thin barrier and flooded the mine. If it proves to be a pocket of water, very valuable mineral will be found behind it, as that has been the rule heretofore. In this case the water can be pumped out in thirty days, but if it is a water-course the mine will have to be abandoned.”
