A detailed description of some of these features and the changes which 
have taken place in thirteen years, as shown upon the two maps, form an 
interesting demonstration of stream work. 
The island at I has disappeared. The horse shoe near M has been 
cut off, a beech tree removed from its center, and the whole area converted 
into flood channel. The next bend to the west has been widened and 
rounded (all done at two or three spring freshets), and the neck nearly 
cut through. ‘The sharp bend at D has also been widened and the tongue 
shortened. The cut-off channel across the neck of bend B, a foot deep 
thirteen years ago, has not been enlarged, and the cut-off, then apparently 
imminent by overflow, is now likely to take place soon by lateral erosion 
of the neck. The south bank opposite S has been cut back twenty-five 
feet, including a large beech tree. West of S the north bank has been cut 
back forty feet including a large maple. Near P the stream strikes and 
undercuts a boulcer clay bluff, turns to the north and ceases to meander. 
The general result is a notable enlargement of the area of the flood chan- 
rel floor, which has become a new flood plain, leaving the old one as a 
terrace.
