have based the arguments of this paper upon Naragansett, 
rather than upon Buzzards bay, is due to the fact that it is 
only in the former case that any detailed description of the 
•sand plains has been published. 
The theory of submergence would be much simplified in 
its application to the Narragansett bay region if it were 
possible to regard the Greenwich Cove and Barrington stages 
as contemporaneous. This Mr. Woodworth regards as im- 
probable. The irregularity of the ice margin demanded under 
these conditions is no more than that shown bv plains in 
other localities, and is at least within the range of possibility. 
. The tendency to long north and south depressions held open 
by the ice in the region in question is by no means unfavorable 
to the theory. 
REVIEW OF RECENT GEOLOGICAL 
LITERATURE. 
The Geological Structure of ShaiitU7ig [Kiautschou) with particular 
reference to the deposits of useful )ni7ierals. \Der geologische Bau von 
Schantung [Kiautschou) mil Ijesonderer Beruchtigung der nutsbaren 
Lagei'stdtten.] By Ferdinand v. Richthofen. (Zeitschrift fur prak- 
tische G?o!()gi.>, pp. 73-84, March, 1898.) 
This article by privy councillor Dr. Ferdinand von Richthofen upon 
the economic geology of the Shantung peninsula of China is of especial 
importance at the present time because of the recent acquisition of the 
part of Kiaochau by Germany. From this article we take the following: 
The province of Shantung was visited by Ferdinand v. Richthofen 
at the beginning of his trctvels in China in the year 1869. No geological 
investigations had been made prior to that time, and since there was 
also no reliable topographical map he was compelled to make one him- 
self. The scale of Richthofen's map is 1:437,000. It also appears on a 
smaller scale in his atlas of China in which Shantung appears on pages 
I to 4 and 53 and 54. 
The province is chiefly level ground, a part of the great plain of 
China, only about 2/7 of its area being mountainous. The mountain 
chain surrounds the entire peninsula and extends westward across it 
forming an island-shaped area enclosed by plain and sea. The great 
plain is an eruptive table-land and the underlying rocks are of unknown 
age. The surface features are sculptured by the Hwang-ho and other 
streams, each of which has at some time been one of its tributaries.
