DAVIS: RIVER TERRACES IN NEW ENGLAND. SLT 
the stream of Figure 31 be supposed to have returned from a swing to 
the eastern side of its valley floor. It will now be at a lower level than 
before and will therefore be halted somewhat in advance of the defended 
cusp previously developed. Figure 33 shows the blunt cusp of a slip- 
ping meander thus determined. Another swing out and back having 
been accomplished, Figure 34 shows the work of a compressed meander, 
A, which for a time was held up-valley from a third exposure of the 
long-sloping ledge ; but the stream was then withdrawn from its round- 
about course by a short-cut, after which a sweeping meander wore out 
the three short curves, B, down-valley from thre ledge ; and still later 
the next down-sweeping meander, C, trimmed off- the terrace front close 
to the ledge preparatory to slipping past the obstacle and pushing still 
further back the down-valley side 
of the terrace front. Another 
stage is shown in Figure 35. Here 
the eighth westward swing of the 
stream is recorded (compare Fig- 
ure 25). Part of the plain formed 
by the second swing happens to 
be still preserved, but not of the 
first and third. All the later 
swings, fourth to eighth, are well 
indicated. A strongly-compressed meander of the eighth swing has 
trimmed off all- the terraces a little distance up-valley from their ledges, 
and would have trimmed them still closer but for being withdrawn by 
a short-cut. A later meander of the same swing is less successfully 
wearing away the down-valley extension of the terraces. 
It is evident that an infinite variety of terrace patterns may be ex-
