DIASTROPHISM AND THE FORMATIVE PROCESSES. III 
THE LATERAL STRESSES WITHIN THE CONTINENTAL PRO- 
TUBERANCES AND THEIR RELATIONS TO CONTINENTAL 
CREEP AND SEA-TRANSGRESSION 
T. C. CHAMBERLIN

In the second article of this series—preceding number of this 
Journal, pp. 517-33—it was urged that ordinary diastrophism 
springing from internal stresses is, in its very nature, unsuited to 
adjust the surface of the earth to the surface of the sea over wide 
areas with such close nicety as effectively to facilitate the great 
sea-transgressions and the formation of the great terranes of 
marine sediments that spring from them. This inadaptability is 
held to arise chiefly from the fact that the deforming earth-stresses, 
on the one hand, and the working relations of the sea-surface to 
the sea-shelves, on the other, are so far independent of one another 
in origin and mode of action that they are not naturally co-operative 
in so close and harmonious a way as to be suited to produce the 
observed results, since these are obviously the effects of nicely 
adjusted relations. 
So, too, it appeared that such vertical stresses as may arise 
from loading and unloading in the process of gradation are unsuited 
to produce these results, because loading and unloading tend to 
produce a warp between the loaded and the unloaded tracts,
