Geography of Eastern Asia. — Hobbs. 71 
"The crescents (Dogen) which form these borders, all of them 
turned to the southward, point to a connection of the parts of this entire 
extended region, and if one examines the eastern coast of Asia along 
which repeated island-crescents and the bands of islands are strung as 
upon no other coast of the globe, the thought is forced irresistibly upon 
one that a common cause must lie at th.c basis of this marginal festoon- 
ing of the Asiatic continent." 
Further he says : 
"These examples and problems may suffice. They show that the 
most important facts in the largest numbers which it has up to the 
present been possible to discover respecting the position of tectonic lines, 
relate to Europe and the borderland of Eurasia. A binding together of 
the parts, and any sort of synthesis, would not have been possible at 
the time of the appearance of the second volume, for the reason that 
all interior parts of Asia, in which tht connection of the crescents 
must be sought (Siberia and Mongolia), were almost completely un- 
known. The latest works of Russian explorers have for the first time 
furnished the possibility of such an attempt." 
To review the more than five hundred pages of Suess's 
work, packed as it is with local data carefully digested and 
correlated with those of neighboring regions, would be to 
write a more or less extended treatise upon Asiatic geology. 
The book is, moreover, accessible to most readers of geological 
literature. It is sufficient to state that the same principles 
which were shown to be so important in determining the broad 
features of European topography and geology apply equally 
to the Asiatic continent. The evidence that deforming agen- 
cies responsible for tectonic structures and for surface features 
of the first order of magnitude have been operative through- 
out the entire region, have been supplied with only less full- 
ness. The great importance of disjunctive processes, which 
have allowed the sections of the earth's crust to move up or 
down with reference to each other, thus dividing the country 
into plateaus or landsteps, is no less forcibly presented than 
was done in the earlier volumes. 
With this first half of the third volume of Das Antlit:: der 
Erde is printed a map upon which some of the larger lines 
of faulting have been indicated. The portion of this map 
which comes within the region here under consideration has 
been reproduced in figure i. The course of the Ho-ang or 
Yellow river is indicated upon the map in its southern portion, 
and the great plain of China by the white area in the extreme
