lanthvs oceidentalis is also abundant. It is a clear fresh water lake and 

 is nearly level with the upland flat prairie. Lake Euitah, in sec. 5, T. 

 9 N\, E. 5 E., is another quite large body of water. 



Before closing I will mention a natural curiosity in sec. 32, T. 10 N., 

 B. 7 E., on the west side of Little Wabash river, a quarter of a mile 

 above a saw mill. Two elm trees grow close to each other, relatively 3 

 and 2£ feet in diameter ; from the latter a large limb branches off about 

 4 feet above the ground, crossing to the other tree, to which it soon 

 unites, then separating again, but solidly uniting at 40 feet from the 

 ground, forming one trunk of three feet in diameter.
