structures as are shown in the several excellent photographs of sections of 
the upland formations. This questioning would be more pointed, if the 
chemical and physical state of these deposits had been more critically 
described. Question will also arise whether the little bluffs called sea- 
cliffs are really such. They look much like the terrace edges cut by low- 
gradient drainage. ‘The digitate borders of the formations as mapped on 
Plate I, and on the restorations of the sea limits of the several stages as 
mapped on Plates XXVII-XXX, present strange alignments for the puta- 
tive shores of the Atlantic. The little off-shore islands of soft material 
seem equally strange features. So also one looks in vain for the great 
sand-bars and strong beach deposits that are usually associated with ocean 
borders. If critical inquiry is turned to the elevations of the several parts 
of the upland formations, there appears to be a closer resemblance to the 
habitual hypsometry of terrestrial formations than to that of marine. One 
does not find in the report evidence of a clear perception of the methods 
of terrestrial deposition, such as are applicable to a region of this kind, and 
one is left with the suggestion that, when the region is critically studied with 
terrestrial criteria sharply in mind, the upland formations will be found 
to be typical terrestrial deposits, as implied by the fossil evidence. A part 
of the lowland Pleistocene is undoubtedly marine. 
The systematic treatment of the paleontology of the Pleistocene deposits 
is an admirable feature, and will prove very serviceable in the study of the 
Pleistocene formations of the coast both to the southward and to the north- 
ward where warmer and colder faunas, respectively, were prevalent.
