oscillations of the shore line resultant upon alternating elevation and 
subsidence, but the average position of the coast was not greatly 
changed from the position first assumed, for it was now on one side 
and now on the other of the Martinsburg shore; (3) the Massanutten 
syncline marks the site of an oflf-shore zone of maximum deposition, 
and is therefore illustrative of the hypothesis of original synclines: 
(4) the general post-Carboniferous folding of the Appalachian province 
was shared by the Massanutten region; (5) since Paleozoic time the 
region has been several times elevated, suffering, during the intervals- 
between the uplifts, more or less complete degradation, at least three 
and perhaps four such uplifts being recognized in remnants of base level 
surfaces; (6) the latest upward movement of the land has been so recent. 
that its efifect is still evident in the grades of the rivers of the region. 
Not the least valuable features of the paper are the synoptic arrange- 
ment throughout, terseness of statement, and the general absence of all 
those unnecessary details which so often burden most literature of this 
kind.
