to find both statements erroneous. Investigation was set on foot with 
the results detailed in the treatise above named. 
The phenocrystalline granite which forms the basal layer on which 
repose sandstones of Eocene (?) age was heavily eroded before the lat- 
ter were deposited. Both series have been subjected to deformation 
which has resulted in folding and crumpling the sandstones and in 
faulting and shearing the granite. Both were again eroded before the 
Miocene deposits were laid upon them. To the former the author ap- 
plies the term "Tejon series" and to the latter that of the " Monterey 
series." Above both are various beds of conglomerate, sandstone, 
gravel and clay — the "terrace formation." 
A description of the "St. Lucia granite," as the basal mass is called, 
comes next, accompanied by an account of the dykes of later granite, 
pegmatite, etc., which traverse it. By evidence obtained elsewhere the 
date of the former is shown to be pre-Cretaceous. 
The evidence of the Eocene date of the lower series in the absence 
of fossils is indirect, being derived from a correlation with similar 
rocks in Malpaso caiion. But the Monterey series has yielded charac- 
teristic Miocene fossils. Among the deposits of this series is a white 
shale 1,000 feet in thickness, containing in many places infusorial re- 
mains. This bed is believed by the author to be the product of the fine 
ash of a very acid volcanic eruption. 
Then follows a technical description of a new mineral found in the 
volcanic series for which the name "iddingsite" is proposed. It is said 
to be characteristic of the series, for which as a whole the term "Car- 
meloite" is devised. 
Abundant evidence was found of the former occupation of the shores 
of Carmelo bay by the sea, up to 800 feet of elevation, in terraces, 
beaches and deltas, with cliffs showing borings of Pholades. Later 
elevation is therefore indicated to that amount. 
The authors indicate their conclusions thus: — 
" The Pliocene corresponds to the period of more or less continuous 
depression of the coast till the land was at least 800 feet lower than at 
present and the Quaternary corresponds to the more or less continuous 
uplift which has affected the coast since the maximum depression was 
reached." 
Regarding the off-shore submarine channels to which attention has 
lately been drawn, Dr. Lawson says that there is no evidence of eleva- 
tion since Miocene times above their present altitude. He inclines to 
regard the submarine valley which heads in Carmelo bay as a continu- 
ation of the old canon of the San Jose which has all the characters of 
a fault, while the depression in which lies Monterey bay is, he thinks, 
a synclinal valley and not a channel of erosion.
