INTRODUCTION. 
In a recent publication the writer presented a résumé of the 
present state of knowledge of the geology of the California Coast 
Ranges.’ It is intended to devote the present article partly to a 
more detailed statement of views expressed in that paper on the 
relation of the Miocene, Upper and Lower Cretaceous to each 
other, which could not be fully discussed for lack of space, and 
partly to the presentation of additional evidence in support of 
the writer's published views concerning the existence of a pre- 
Cretaceous (pre-Knoxville) series of rocks in the Coast Ranges. 
Most of the observations on which the opinions presented are 
based were made during the summers of 1891!1-2-3. Valuable 
additions were made the past fall, when in company with Mr. F. 
M. Anderson, a student in Stanford University, a three weeks’ 
trip was made through the Santa Lucia Mountains in Monterey 
and San Luis Obispo counties.
