beveling of the upland fjelds of Norway by means of the 
broadening of kaJirc floors under the action of local glaciers 
(Sitzungsber. Akad. Wien, 1896?); but it is manifest that all 
such processes are applicable only at altitudes above 5,000 or 
6,000 feet in New England, as Q, fig. 2, and hence cannot be 
directly concerned in producing beveled hill tops at altitudes 
of 1,000 feet or less. In uplifted peneplains, where the up- 
lands bevel across from valley to valley, it is manifest, as has 
already been pointed out, that existing processes are engaged 
in destroying, not in producing or perfecting the uplands. 
Indeed, the production of beveled hill tops, as here interpreted, 
seems to me so inherently impossible that I am for that reason 
persuaded that all this paragraph must be aside from the in- 
tention of Professor Tarr's theory. And yet, unless the sys- 
tematic beveling of hill tops is some how accounted for, the 
theory must fail to explain the most essential features of those 
regions conmionly regarded as uplifted and partly dissected 
plains of denudation. 
Perhaps the change of form intended under the term, bev- 
eling, applies only to the mountain slopes, so that FJK, fig. 
3. becomes FLK. If so, it does not materially modify the 
changes considered in the last paragraph of section C 2, and it 
leaves unexplained the important feature that I should call 
"beveling of hill tops,*' as considered just above. I hope that 
this important matter will be more fully presented by Pro- 
fessor Tarr. 
An C 4. Donidation and bevelifig will be more advanced near 
me coast than in the interior. It is urged that near the coast, 
"mountains would have been more lowered than in the in- 
terior, and, in the coastal region, there may well have been an 
approach to the peneplain condition" (p. 366); and again that 
"this beveling of the hill tops would be very much further ad- 
vanced near the coast than in the interior, thus coinciding with 
the conditions found in New England" (p. 368). The brief 
statement allotted to these important propositions must leave 
the reader somewhat in doubt as to their explanation. As far 
as I can analyse them, they are not applicable even to the case 
of New England, much less to various other cases cited above. 
The ancient mountain trends of southern New England are 
obliquely traversed by Hie shore line of Long Island sound.
