SUBTERRANEAN FIRES. The people of Plummer’s Landing, Fleming county, Ky., are reported as being panicstricken because of the mysterious subterranean fires which are burning on J. T. McGregor’s farm, near there, and are preparing to move away if dangerous symptoms arise. The fire is burning under an area of about 200 square yards, and the ground for that space has sunk about a foot. A dense smoke or vapor is rising all the time, and has the smell of horning coal. The ground that has sunk is so hot that one can stand on it for only a few minutes.
