fall increases slightly, and soon after entering Section 26, T. 10 N., R. 3 W., 

 the stream lias cut down to bed rock. The road leading east and west 

 along the north side of Section 26 is practically the margin of Flatwoods 

 in this vicinity. On this road a shallow ford crosses the creek on the 

 700-foot contour line, over a solid rock floor. From the source of the 

 stream to this ford, a distance of about five miles, the stream has a fall 

 of about fifty feet. It enters White River about two miles below, at an 

 elevation of 540 feet above sea level. Thus the last two' miles of the 

 stream have a fall of 160 feet. Practically the entire last two miles of 

 the course is over a solid rock bed. Tbe region presents some of the most 

 rugged and beautiful scenery in the State. The stream courses down a 

 veritable gorge which is but little wider than the stream itself. Many 

 cascades occur, and about a mile below the ford a fall of about 12 feet 

 occurs. In low water the stream cascades over this fall, but when the 

 water is high it rusbes over with a roar that can be heard for some dis- 

 tance. Above the falls tbe floor of tbe gorge is swept clean of debris, but 

 below, the gorge is wider, and in many places is chocked with the rock 

 debris that has been carried from above or has fallen from the almost 

 vertical walls on either side. 



Just east of the source of McCormicks Greek is the source of a small 

 branch which leads northeast through an opening in tbe rim of tbe basin 

 and empties into Jacks Defeat Creek. This stream drains but little of 

 Flatwoods, as indicated by the map. Its source is about the same heigbt 

 as the McCormicks Creek source, and its mouth, one and one-third miles 

 northeast, comes out at about 670 feet above sea level, thus giving it a 

 fall of eighty feet. 



Another break in the rim of tbe basin occurs in Section 30, T. 10 N., 

 R. 2. W., about two miles soutbwest of Stinesville. This opening is nar- 

 row and its surface is below the 760-foot contour line. To the north of 

 the narrow opening is a wide flat plain similar to the Flatwoods, hav- 

 ing a silt surface of the same nature. Tbis flat is drained into Big Creek. 

 The narrow opening itself is practically bed-rock at the surface. ' Sinks 

 occur in it. A small portion of Flatwoods is drained into a deep sink 

 near the northwest part of this section. The water that goes into this 

 sink undoubtedly passes under tbe narrow opening and comes out into 

 Rig Creek below, as several springs occur in the upper part of this creek. 

 Just to the west of tbis narrow opening is a high hill capped with sand- 

 stone, which is at least sixty feet higher than tbe opening. The silt line
