(16) also believed that peat deposits when checked by dryness form 
a parting layer between 
an old and a new bed of 
peat which takes on the 
shape of a dry layer. 
With increasing 
study of the structural 
features of American 
peat deposits, correla- 
tions of various kinds 
will undoubtedly de- 
mand more considera- 
tion and will assume 
their basic importance. 
At present, however,: it 
appears to be well 
founded to regard ap- 
parent structural climax 
layers as depending 
mainly upon the con- 
tinuation of certain re- 
gional field conditions. 
It has already been 
suggested that the struc- 
tural development of a 
peat deposit may fail to 
terminate on account of 
unfavorable local field 
conditions, and that 
various factors may in- 
hibit a further develop- 
ment or may produce 
secondary stratigraphic 
features of varying 
character. There ap- 
pears to be little doubt, 
however, that whenever
