this point, the north stream taking a due west course to reach 

 the Little Miami River ; the other a south-west direction to 

 reach the same stream nearly three-fourths of a mile below 

 the mouth of its companion. 



At the neck of the peninsula the north stream has formed 

 a ravine fully seventy feet in depth ; while the one to the 

 south has acquired a depth of from thirty-five to forty feet. 

 From the brow of the north ravine, in a S. S. W. direction, to 

 the brow of the .south ravine, the distance is about sixty-two 

 rods. The direction here indicated is that taken by the line 

 of high embankments in crossing this neck of ground. But 

 the line is by no means .straight. To follow its devious 

 course the distance is about seventy-five rods, or thirteen rods 

 greater than a direct line. 



On this neck of land, about midway between the large 

 ravines, rises a little stream or branchlet, which runs south, 

 bearing a trifle west to enter the large ravine that lies in this 

 direction. It is only about thirty rods in length, but by the 

 time it reaches the ravine it has excavated a bed fully twenty 

 feet in depth. In the upper part of its course it makes quite 

 a curve to the west. 



About eight or ten rods north of the head of this branchlet 

 rises another similar stream, which runs north, bearing a little 

 west, to enter the north ravine. It is from twenty to twenty- 

 five rods in length, and in its course curves somewhat to the 

 east, or in an opposite direction from the one just described. 

 This branchlet, a few yards before it enters the large hollow, 

 is joined by another tiny stream coming down from the 

 southeast. It is only ten or twelve rods in length. 



It is proper to state that the two branchlets first described, 

 particularly in their upper parts, are not at this time well 

 defined. The wearing down of the high embankments, which 

 were constructed immediately on their western borders, and 

 the cultivation of the adjacent fields have, in places, almost 

 obliterated them. This is noticeable particularly with the one 

 that enters the north ravine. It is at this time well defined 

 only in its lower part, where it has formed a gully fifteen feet 

 in depth. The construction of the Chillicothe and Lebanon 

 turnpike, which emerges from the Fort here, contributed to 

 its obscurity. A number of years ago we were informed by
