Ellis Cave.—On the estate of Dr. Ellis, 19 miles north of Fort Payne and 3 miles from Sulphur Springs, are two caves known locally as Big-mouth and Little-mouth. The smaller is closed by a locked gate. The larger has a rather imposing appearance from the outside. From a ledge of rock, in place, in front of it, one looks down a steep slope in which rocks up to 40 or 50 tons weight are imbedded. At a vertical depth of 30 feet is a level space not more than 8 or 10 square yards in area. From this a narrow crevice goes to the right. Within a few yards it reaches a hole which can be descended only by means of a rope or ladder. Persons have, however, gone several hundred yards in it.

On the left of the level space and bounded on each side by solid rock walls is a pit 10 feet deep, caused by inflowing storm waters which have created this depression in seeking a small outlet, also toward the left. The height from the bottom of this sink to the roof of the cave is nearly 50 feet.

Crossing this pit on a foot log, which rests on loose rock and earth at its farther end, a crevice varying from 6 to 10 feet wide goes inward for 50 feet. Earth covers the loose rock at the level of the foot log almost at once, and this earth has a steep ascent toward the rear. The crevice widens beyond the distance mentioned, though irregularly, being in some places 25 feet from side to side. So far as progress is concerned, the cave terminates 150 feet from the doorway in a blank wall. It may be that if the earth were out of the way further progress would be possible.

Considerable digging has been done for saltpeter, but except near the front it has been only superficial.

The top of the earth at the extreme rear of the cave is almost or quite as high as the roof at the front, which means that, if the bottom should be level, the thickness of this accumulated deposit is not less than 35 feet. As the dip is toward the rear and quite sharp, about 10 or 12 degrees, the earth here may well be much thicker than indicated.

Excavation would be tedious and costly, as it would be impossible to dispose of the dirt except by blasting a deep trench through the rock in front to make room for wheeling it out.

Killian Caves.—There are two of these, both on the west slope of Lookout Mountain. One is near Brandon, 6 miles south of Fort Payne. The entrance is a large sink hole on the side of the mountain, descent into which is difficult owing to the steepness and large rocks. At the bottom the water which flows in over the muddy floor from the slope above—several acres in extent—rushes into a hole choked with loose stones and disappears.

The second cave is about 3 miles northeast of Collinsville. Débris from the mountain has formed a wall across the entrance, which is naturally wide and high and opening out on a little flat in front. Some digging has been done for saltpeter at the front part of the cave, reaching about 30 feet back from the inner foot of the accumulation. In the pit thus formed water stands after every rain until it soaks away. Where it ends the "face" is about 5 feet high. On top, farther in, there is much travertine or stalagmite; in some places it extends entirely across the floor. In other places the floor is bare. There is constant drip, and in one room there is a little gully, where surface water in wet weather, entering from a small branch cave on one side, has cut an exit through the earth at the foot of the wall on the other side. The hole in which it disappears extends beyond the rays of a lamp, and a stone thrown in goes down a slope several feet in length. Very little working is needed to reduce any of the earth to soft, slippery mud, hence no excavation was possible.

MARSHALL COUNTY

Fearin Cave.—This is in a bluff on the right bank of the Tennessee River, 10 miles below Guntersville. It has three divisions. Shortly after passing the spacious entrance a branch turns to the right. In a few feet a wall is reached which can be scaled only with a ladder. Climbing this, a large chamber is reached, totally dark, and the home of innumerable bats whose "guano" covers the floor and fills the air with a stifling odor. This branch comes to light again more than a mile away on the side of the mountain.
