354 Lawson (Andrew 0.). The geoinorphology of the coast of northern 
California. 
Univ. of CaL, Dept. of Geol., Bull., vol. i, pp, 241-272.

fornia coast line in Pliocene time and of the more recent subsidence of 
the Golden Gate. 
355 A multiple diabase dike. 
Am. Geol., vol. xiii, pp. 293-297, pi. vii. 
Describes a diabase dike occurring on an island near the northeast 
coast of Lake Superior, in which the dike is split up into 28 verti- 
cally intrusive sheets in a breadth of 14 feet. These sheets represent 
but one invasion of the magma, and the granite which they penetrate 
is apparently homogeneous.

Describes the occurrence of this sandstone in Washington, mentions 
the fossils found in it, -which indicate that it belongs to the Eocene or 
Miocene, and discusses its bearing in determining the age of the Puget 
group.
