Miscellaneous Notices.
BY WILLIAM P. BLAKE,
Professor of Mineralogy, Geology, and Mining, Dept. Sci. Coll. of
California.
I. NEW LOCALITY OF FOSSILS IN THE GOLD-BEARING ROCKS OF
CALIFORNIA.
I have obtained specimens of _Ammonites_ from the cut in the
rocks on the line of the Central Pacific Railroad, about two
miles below Colfax, and in the heart of the main gold belt of
the State.
The rock is a compact argillite, somewhat altered and much
discolored by the peroxydation of iron. The strata are boldly
flexed and are interstratified with coarse grits and a thick
bed of conglomerate, so much altered that the pebbles are
homogeneously cemented.
The substance of the fossils has been removed by percolating
waters, but very perfect casts of them remain and show the
details of the external form, but do not permit the septæ to
be seen. It is thus not possible, perhaps, to determine the
specific characters; and considering, also, the absence of a
typical collection and works of reference, I do not attempt
a minute description, preferring to refer the specimens to a
palæontologist. It may, however, be observed that the fossils
are undoubtedly of the secondary period; and that they are
apparently specifically identical with those from the American
river, in the same vicinity, of which I sent photographs to Mr.
Meek, at the Smithsonian Institution, in 1863, and afterwards
noticed at one of the meetings of this Academy, in September,
1864. They are, also, apparently identical with the species
found in the Bear Valley, Mariposa, slates. If this species
has not been already named, I desire to connect with it the
name of Mr. Spear, in whose cabinet at Georgetown, the earliest
specimen was carefully preserved. I obtained one specimen at
the locality, and another was presented to me by Mr. Richard
Carroll, it having been saved by the quarry-men, under the
impression that it was a petrified rattlesnake. It is about six
inches in its longest diameter, being elliptical and evidently
distorted by lateral pressure.
II. TOOTH OF THE EXTINCT ELEPHANT, PLACER COUNTY.
I have received from Mr. Baker and Mr. Thompson, through the
hands of Mr. E. Tyler, all of Placer County, a single molar
tooth of _Elephas_ found in the auriferous gravel near Michigan
Bluffs, thus adding another locality to the list showing the
former general distribution of the ancient elephants over this
coast.
III. SHARK TEETH AND OTHER MARINE REMAINS, TULARE COUNTY.
When at Ocoya or Posa Creek, in 1853, I collected a great
number of shark teeth from the tops of the hills, at the
base of the Sierra Nevada, on the east side of the Tulare
Lake. These were described and figured in my Report to the
U. S. Government. Having recently revisited that region,
I found other localities, and made another collection, a
part of which I now exhibit to the Academy. The following
genera and species are represented: _Oxyrhina plana_, _O.
tumula_, _Lamna clavata_, _Galeocerdo productus_, _Prionodon
antiquus_, _Hemipristis heteropleurus_, _Notidanus_, (Nov.
Sp.?) and _Zygobates_, a genus of the family of Skates, having
pavement-like teeth. Vertebratæ, apparently of the whale, are
abundant, and some fragments of the head. These remains are
now at least twelve hundred feet above the sea, and being in
unbroken horizontal strata, show a very great and general
uplift of the region in comparative late times. The strata were
referred to the Miocene in my Report, but I am now inclined to
regard them as Post-Pliocene. It is interesting to note that
these strata rest undisturbed upon granite, which is traversed
by gold-bearing veins, not over five miles from the point where
the fossils are found, and so low that the veins must have been
covered by the sea prior to the elevation of the region.
IV. QUARRY OF GOLD-BEARING ROCK.
The Baker or Whiskey Hill Mine of Placer County, a few miles
from Lincoln, presents the novelty of profitable gold mining
from a _quarry_ in the slates without any well defined quartz
vein. A hill with a rounded outline is covered with rough
outcrops of rusty slate, over a breadth of two hundred feet
or more. A quarry at one end exposes the slate, with a great
variety of colors, from white to brown and red and black, the
whole of it being soft and ochraceous, and in places stained
green and blue with carbonate of copper. These variegated
slates are like those commonly known, among California copper
prospectors, as “calico rocks,” and the ground was first
located and prospected for copper.
It is evident that the formation consists of beds of iron
pyrites (mundic) with a small but variable portion of copper
pyrites, and that the rusty, upper portions are due to the
gradual decomposition of the sulphurets above the permanent
water-line, or where the atmosphere has had access. Below the
water-line we may not expect to find the rusty ochrey slates.
This is shown, also, at a shaft which has reached the water.
Blocks of mundic, taken out of that shaft, are interstratified
with talcose slate. At one point, in the bottom of the quarry,
a layer of green and blue carbonate of copper is found, and
this is evidently the result of a gradual concentration of the
copper from the decomposed ground above. The soft slate, as
quarried, is trammed to a five-stamp mill, with very coarse
grates, and nearly forty tons are run through it daily. The pay
is said to vary from two to twenty dollars, but the average is
reported to be from five to six dollars per ton.
Mr. Stearns read the following:
Since my communication to the Academy of date July 16th last,
on the Shells of Baulines Bay, additional specimens (4) of
_Haliotis rufescens_ have been found by Mr. Harford and Dr.
Kellogg; also many specimens of _Katherina tunicata_, and one
of _Mopalia Hindsii_; from between the umbos of very large
specimens of _Mytilus Californianus_, collected by the same
gentlemen, several specimens of _Barleia? subtenuis_ Carp.
In addition to the above marine forms, the following species
were found by the same parties in a gulch at Belvidere Ranch,
not far from Capt. Morgan’s house, south side of Baulines
Bay: _Helix Nickliniana_, _H. arrosa_, _H. infumata_, _H.
Columbiana_ (hirsute var.) and _H. Vancouverensis_. Also,
near a small stream on the same ranch, _Bythinella Binneyi_,
Tryon. The last named species had previously been found in this
neighborhood by Rev. J. Rowell.
Prof. Blake mentioned that a tooth of a mastodon had been found about
three miles from Antioch, near Monte Diablo, by Capt. Stevens.
Mr. Stearns gave an account of the Helix, its anatomy, geographical
distribution, and use as an article of food and for medicinal purposes,
in both ancient and modern times.
Prof. Blake stated that he had in his possession a portion of a human
skull said to have been taken from a depth of 250 feet below the surface,
near Columbia, in Tuolumne County.
REGULAR MEETING, SEPTEMBER 3D, 1866.
President in the chair.
Twelve members present, and Mr. A. Wood as a visitor.
Mr. John Swett was elected a Resident Member.
Donations to the Cabinet: Two specimens of fishes from Dr. Kellogg and
Dr. Behr; specimen of a fungus, _Polyporus igniarius_, from Dr. Kellogg.
Dr. Kellogg called the attention of the Academy to the remarkable
specimen of fungus presented by him, _Polyporus igniarius_, which was
found growing upon the Bay tree, _Oreodaphne Californica_; and gave
a description of _Fungi_ in general; alluding particularly to the
destructive effect of many species, some producing the dry rot in ships,
others destroying buildings, producing the disintegration of mortar in
masonry, and seriously affecting the health, or destroying animal life.
Dr. Kellogg also remarked on the use of some species of Fungi for food,
particularly by the natives of Australia, who regard them with especial
favor for that purpose. The rapid growth and poisonous effect of certain
species of Fungi were mentioned, also the use made of some species in the
arts.
Mr. A. Wood, who has recently returned from a botanical exploration of
Oregon, being present as a visitor, was invited to speak, and gave the
following narrative of the recent ascent of Mount Hood, by himself and a
party of gentlemen:
On the 20th of August last, in company with Dr. Atkinson,
of Portland, and the Rev. J. Deardorff, of Walla Walla, and
three others, I stood upon the summit of Mount Hood in Oregon.
From our last camp on the summit of the Cascade Range to this
point, the summit of Mount Hood is eleven miles of constant and
weary ascent, at angles about as follows: Five miles in the
first, 12 to 15°; two miles to eternal snow, 25 to 30°; one
and one-half miles to the gap in the rim of the crater, about
45°; the remaining ascent traversing the ancient crater, nearly
or quite 60°! The day was cloudless; a strong, warm wind from
the southeast softened the surface of the snow and favored our
ascent, although it gave us much anxiety lest it should loosen
some of the tremendous acclivities of snow and overhanging
drifts from above us.
Starting from camp at daylight, on horseback four miles, we
arrived at the top at a quarter past two P.M., in nine and a
half hours.
Our apparatus for measuring the heights consisted of two
barometers, (aneroid) a thermometer, a tin cup, and a spirit
lamp. Both barometers failed us, the index ceasing to turn
after something more than a complete revolution on the dial.
They were not made for such heights. But we made good use of
our thermometer.
The ascent was exceedingly difficult, and not without danger.
The long summer heat had undermined the snows, causing their
surface to conform more to the ruggedness of the mountains,
and the slides had opened chasms of invisible depths across
our path. We looked down into several of these chasms and saw
that the massive walls below consisted of solid, blue ice, and
terminated at length in the blackness of darkness. We could
hear the noise of running water, apparently in torrents. One
of these chasms was unavoidable—_and must be crossed_. Its
transverse length was nearly a mile, and its width from ten
to one hundred feet. By the aid of a rope, forty-five yards
in length, and five pike-poles, each eight feet, we crossed,
(of course at the narrowest place) and afterward by rope and
poles, tugging, panting, dizzy, we dragged ourselves up to the
terrific crest of this Mountain Monarch.
The summit area is of very limited dimensions—a crescent in
shape, half a mile in length, and _three_ to forty or fifty
feet in width. It is a fearful place, as it is the imminent
brow of a precipice on the north, sheer down not less than a
vertical mile of bare columnar rock!
This height is lifted so far above all other heights (except
the four distant snow-clad peaks to the north and Mount
Jefferson on the south) that the country beneath seemed
depressed to a uniform level, and the horizon retreated to the
distance of more than two hundred miles, including nearly all
Oregon and Washington Territory. The sublimity and grandeur
of that view I must leave to the imagination of the reader. A
cañon of enormous depth plunges down along the southeast flank,
and is filled in part by a glacier evidently in motion, and
having below a very abrupt termination. Terminal and lateral
_moraines_ mark its course, and a torrent of water issues from
beneath. While we delayed here, an avalanche of rocks, an
immense mass, started by the wind, thundered down the left wall
of this cañon several thousand feet, and its track was marked
by a trail of white smoke.
On the west side of the ancient crater, at the base of a vast
craggy pinnacle of rocks, (a portion of the ancient rim of the
crater) is still an open abyss, whence issue constantly volumes
of a strongly sulphurous smoke. That there is also heat there
is evident from the immense depression of the snow about this
place—depressed not less than a thousand feet below the snows
which fill to the _brim_ other portions of the ancient crater.
As I have already stated, we found our barometers useless
in these vast heights, and were reduced to the use of the
thermometer alone. By this we learned the boiling point of
water at four several stations, as follows: At the camp, the
summit of the Cascade Range, it stood in boiling water at 204°
Fah. At the upper verge of the forest, it indicated 195½°.
At the highest reach of all apparent vegetation, 192°; and
finally at the summit, where, after the most persevering and
determined efforts, (on account of the violence of the wind)
we at length, by means of a spirit lamp, changed a portion of
snow to a cup of boiling water, the mercury stood firm in the
cup at 180°! These several results being changed to _feet of
elevation_, according to the rule universally approved in such
cases, indicate heights as follows, viz: At the summit of the
Cascade Range, and foot of Mt. Hood proper, 4,400 feet; at the
limit of forest trees, about 9,000 feet; at the highest limit
of vegetation, 11,000 feet; at the summit of the mountain,
17,600 feet.
We earnestly hope that these results may be hereafter tested by
the barometer; and by triangulation. Until then, we must adopt
the estimate here made, as the height of that sublime peak,
and accord to Mount Hood the distinction of being the highest
land in the United States, if not the highest upon the North
American continent.

_Hab._—San Pedro, Cal., estuaries.
Only four specimens were found dead near the old landing, close
to the mouth of the bay, in October, 1861. I supposed them to
be _P. brata Binn_, but they are nearly three times as large,
not lirate, etc. That species is catalogued by Carpenter as
among the collections from San Diego, in the Supp. Rep. etc.,
1863, pp. 612, 647, 673, but I do not find it in the State
collection. Those described are fresh and shining in the
mouth—dull, but not much worn, outside.
This is a very interesting shell, being one of the links
between the land and marine mollusca—the species of the genus
being chiefly tropical, occurring at Cape St. Lucas, Panama,
West Indies, Africa, and Isle of France, according to Binney,
who says that they inhabit crevices of rocks, especially those
exposed to the full force of the tide; but being pulmonate,
they can probably live long with but little moisture. On the
rocks the living shell would be mistaken for a _Lacuna_ or
_Littorina_, and the form of our species reminds one strongly
of _Succinea Oregonensis_.
A communication was received from Dr. Canfield of Monterey, giving an
account of the discovery in Monterey Bay, of a fish, pronounced by
the naturalists of the Smithsonian Institution to be a new species of
_Bdellostoma_, a genus not previously known to exist nearer than the
coast of Chili.
Mr. Falkenau made some remarks on the use and value of the spectroscope
in chemical analysis and in other scientific investigations.
REGULAR MEETING, OCTOBER 1ST, 1866.
President in the chair.
Fourteen members present.
Messrs. A. Winslow Boynton, and T. C. Leonard were elected Resident
Members.
The resignation of Royal Fisk, Resident Member, was received and accepted.
Donations to the Cabinet: A specimen of black oxide of manganese from Red
Rock, by Mr. Stearns; fossils from near Nanaimo, by Dr. Comrie.
Dr. Behr made some remarks upon the _Lepidoptera_ and the four different
stages of their development, noticing the fact that the length of time
of the egg state in some species, for instance the Chinese silkworm,
admits of the transportation of the same to foreign countries, while in
the Californian silkworm, _Saturnia ceanothi_, the period of the egg
state is so brief as to render it impossible to transport the eggs either
to New York or Europe. Dr. Behr also explained the difference between
the larva state in the _Lepidoptera_ and other classes of insects, and
referred to the importance of the larva condition in insects as a basis
for classification, and mentioned many interesting proofs of the tenacity
of life during the _chrysalis_ or _pupa_ state; alluding to the different
classes of moths in which wingless females occur, a peculiarity that is
unknown to the butterflies.
Mr. Bolander stated that in his “Remarks on California Trees,” made at
the meeting of October 16th, 1865, and published in the current volume,
(p. 225) he had referred a small pine growing on the plains between
Mendocino City and Noyo, to _Pinus murcata_; but he could now state
positively that it is the true _Pinus contorta_ of Douglas. He stated
also, that No. 7, noticed on page 227 of that article, is _P. muricata_.
Farther, on page 229, _Quercus Wislizeni_, Englm. is wrongfully referred
to _Q. agrifolia_. _Q. Wislizeni_ is a well characterized species with
biennial fruit; the fruit of _Q. agrifolia_, on the other hand, is
annual. These two oaks differ also materially in their distribution.
_Q. Wislizeni_ is found chiefly in the lower Sierra, and in the small
valleys east of the redwoods in Mendocino County. _Q. agrifolia_ occurs
almost exclusively in the vicinity of San Francisco Bay, and on the banks
of streams emptying into it. It extends also southward, approaching the
coast more nearly as we reach Monterey.
REGULAR MEETING, OCTOBER 15TH, 1866.
Dr. Kellogg in the chair.
Eleven members present.
Mr. A. L. Bancroft was elected a Resident Member.

Prof. W. P. Blake read the following:
Mineralogical Notices.—No. II.
BY WM. P. BLAKE.
_Kerargyrite._—Chloride of silver in remarkably fine specimens
occurs in the “Poorman lode,” Idaho, associated with Proustite
(light red silver ore), native silver and native gold. Sheets
of the chloride are taken out of the soft clay of the vein, and
are from one-eighth to one-quarter of an inch in thickness. It
is also found in irregular massive aggregations of crystals, in
cubes, without any modification, and over an eighth of an inch
square. The color of my specimens is brown, passing into violet
blue in some portions.
_Proustite._—The “ruby silver” which occurs with the chloride
in the Poorman lode, as above, is often in masses of several
ounces, or even pounds, in weight, and it is reported to be
occasionally seen in beautiful crystals, but none have yet come
under my observation.
_Copper Glance_, _Red Oxide of Copper_, _Native Copper_.—These
species are found together in the “Red Cap claim,” Klamath
County, California, in serpentine. The metallic copper is seen
in points throughout the massive sulphuret, and is sometimes
enveloped in red oxide. Both copper and oxide are most abundant
in the outer portions of the ore, as found, and they are
apparently formed by the gradual decomposition of the sulphuret.
_Danaite._—A cobaltic variety of mispickel is found associated
with iron and copper pyrites at Meadow Lake, Nevada County,
California. It is in distinct, well formed, brilliant crystals,
of a tin-white color, and about a quarter of an inch in
diameter. They are modified nearly as in fig. 289, Dana’s
Min. This mineral gives cobalt reactions before the blowpipe,
and appears to contain a large per centage of this metal. The
ore is said to contain _nickel_, also, and is being mined for
shipment.
_Cinnabar in Calcite._—Cinnabar of a beautiful vermilion color
is found in an unusual form in Idaho, being abundantly spread
through a gangue of massive, compact limestone or marble. It
is so compact and homogeneous that specimens may be cut and
polished like marble. There are no evidences in the ore that I
have received of the presence of other minerals, not even of
quartz.
COLLEGE OF CALIFORNIA, Nov. 17, 1866.
Mr. Stearns read the following:
It is my painful duty to inform the Academy of the decease of
Robert Kennicott. The meager information received furnishes no
particulars, further than that he died suddenly, in the month
of May last, at Nulato Bay, in Russian America.
The services rendered to science by Mr. Kennicott are worthy
of something more than a passing notice. In the month of
May, in the year 1859, we find him starting upon a prolonged
exploration of Russian America, under the auspices of the
Smithsonian Institute, assisted by the University of Michigan,
the Audubon Club of Chicago, and the Academy of Sciences of
the same city. This exploration, including also a portion of
the territory held by the Hudson’s Bay Company, extended from
May, 1859, to the date of his return in October, 1862. From the
Annual Report of the Smithsonian Institute we learn that “the
route traversed by Mr. Kennicott was from Lake Superior along
the Kamenistiquoy River and Rainy and Winnipeg Lakes, up the
Saskatchewan River to Cumberland House; thence nearly north
to Fort Churchill, on English River, up the latter to Methy
portage, at which point he first reached the head waters of the
streams flowing into the Arctic ocean; thence along the Clear
Water River and Athabasca Lake, down Peace River into Great
Slave Lake, and along the Mackenzie River to Fort Simpson. At
this place Mr. Kennicott spent a part of the first winter,
making excursions up the Liard River to Fort Liard in autumn,
and again on snowshoes in January. Before the close of the
same winter he went up the Mackenzie to Big Island, and thence
northwest to Fort Rae, near the site of old Fort Providence.
From this point he traveled on the ice across Great Slave Lake
to Fort Resolution, at the mouth of Peace River, where he spent
the summer of 1860. He next descended the Mackenzie to Peel’s
River, and thence proceeded westward across the Rocky Mountains
and down the Porcupine River to the Youkon, in the vicinity
of which he spent the winter of 1860-61 and the summer of the
latter year. The winter of 1861-2 was spent at Peel’s River
and LaPierre’s house in the Rocky Mountains, and in traveling
from this point to Fort Simpson and back to Fort Good Hope, on
the Mackenzie. He left the last mentioned place on the first
of June, 1862, and reached home in October. This enterprise
terminated favorably, the explorer having returned richly laden
with specimens, after making a series of observations on the
physical geography, ethnology, and the habits of animals of
the regions visited, furnishing materials of great interest to
science.”
Aside from the extensive collections in every department of
natural history, the geographical information acquired by Mr.
Kennicott was of the greatest importance.
In 1865, the Western Union Telegraph Company having determined
to extend their wires so as to connect the old world and the
new by an overland line passing through Russian America across
Behring’s Sea to Russia in Asia, and thence to the central
cities of Europe, Mr. Kennicott’s knowledge of the territory
through which the proposed line was to pass made his services
indispensable to the Company. He was sought out, and his
cooperation at once secured. He entered upon this new labor,
hoping not only to do whatever lay in his power to make this
enterprise a success, but hoping also still further to serve
the great cause that was so dear to him; and while thus engaged
in the enthusiastic performance of this self-imposed duty, in
the prime of life, he has passed away.
Dr. Gibbons made some remarks on the relations of our climate to that of
the Great Basin, and the Eastern States.
He also made some observations on _Zirphea crispata_, living in the bay
near Alameda.
REGULAR MEETING, NOVEMBER 5TH, 1866.
President in the chair.
Fourteen members present.
Rev. S. D. Simonds and Dr. J. Morrison were elected Resident Members, and
Dr. W. P. Gibbons, of Alameda, a Corresponding Member.
Mr. Bolander presented a curiously fruited specimen of _Quercus
densiflora_, the acorns being only about one-third of the ordinary
diameter, although nearly the usual length, and having a peculiar
constriction near the apex. It was collected by Mr. Wertheman, near
Coarse Gold Gulch, Fresno County.
Mr. Stearns exhibited a specimen of an _Astrophyton_, caught in the
Ochotsk Sea, off Cape Lepatka, Kamschatka, by the crew of the fishing
brig Angenette.
Dr. H. Gibbons called the attention of the Academy to the near approach
of the season during which we might look for the recurrence of the
“meteoric shower,” which he witnessed in the year 1833.
Some remarks were made by Messrs. Gibbons, Keyes, Kellogg and others
in reference to the phenomena of meteors, and considerable discussion
followed as to the various ideas and theories advanced in regard to them
by different authors.
Mr. Stearns exhibited several specimens of _Acmæa asmi_, Midd., collected
by him at Baulines Bay; remarking that upon a recent trip to the
locality named, he found this species exceedingly numerous, attached
to _Chlorostoma funebrale_, A. Ad.; that he had not seen in a single
instance this Acmæa upon the rocks. Mr. Stearns further submitted for
the inspection of the Academy, a specimen of _Haliotis Cracherodii_,
which he had collected alive last month, on the rocks near the outlet
of Lobitas Creek into the ocean. The Haliotis had been attacked by a
pholad, probably _Navea Newcombii_, and had defended itself by adding
coating upon coating of nacre, as the Navea progressed, until a large
knob or protuberance had been created in the interior of the shell. From
a partial examination of the borer, a specimen of which he had dug out
from another portion of the same Haliotis, he believed it to belong to
the species recently described by Mr. Tryon, viz: _Navea Newcombii_.
REGULAR MEETING, NOVEMBER 19TH, 1866.

Thirteen members present.
Mr. J. B. Russell and Dr. E. Belle were elected Resident Members.
Donation to the Cabinet: Specimens of Copper ore from Chihuahua, by Mr.
R. C. Jacobs.
Donation to the Library: On the Corals and Polyps of Panama, with

Prof. Whitney presented the following communication from Wm. M. Gabb:
On the Subdivisions of the Cretaceous Formation in California.
BY WM. M. GABB.
The recent appearance of a check list published by the
Smithsonian Institute, and entitled “Check List of the
Invertebrate Fossils of North America—Eocene and Oligocene—by
T. A. Conrad,” renders it necessary that I should state more
clearly than has been done heretofore, the relations between
the two members of the Californian Cretaceous rocks; and should
give all of the proofs that have yet presented themselves, in
support of my views.
In 1856, Mr. Conrad published a paper in Vol. 5, Pacific
Railroad Reports, pages 320, _et seq._, in which he described
fifteen shells from the “Eocene” rocks of the Cañada de las
Uvas, near the present site of Fort Tejon. Of these, eleven
were considered by that author as being new to science. The
other four were referred to previously described Eocene forms.
These specimens were procured by Mr. Wm. P. Blake, geologist of
the expedition. They were obtained from a single boulder, the
only one found by that gentleman.
In consideration of the scanty material, it is by no means
surprising that Mr. Conrad should have made the determination
that he did. The fossils of this locality, and, in fact, of
this member of our Californian rocks, have a marked Tertiary
aspect. This holds good, both as applied to the appearance
of the specimens and also to the grouping of the genera. Mr.
Conrad’s reference of these fossils to an Eocene age was
perfectly justified by the light that he then possessed. Any
other palæontologist, with the same specimens, would no doubt
have done as he did. But I propose to prove that, after having
studied this formation for five years, both in the field and in
the closet—both palæontologically and stratigraphically—after
having traced it upwards of four hundred miles, and after
having collected fossils from it at a dozen localities, I, on
the other hand, am perfectly justified in pronouncing it most
unequivocally Cretaceous.
It is, to use a mild term, rather surprising that Mr. Blake,
from whom Mr. Conrad obtained his material, should not have
collected more specimens. According to his report, Mr. Blake
reached the depôt camp at Tejon, on the third of September,
1853, and did not leave that vicinity until October 10th.
During that time he traversed the distance between Tejon and
the Cañada de las Uvas, four times. I am familiar with every
foot of the ground on which he camped or on which he travelled;
and I speak from personal observation, when I say that in
going from one point to the other he could not avoid passing
thousands of boulders and pebbles, full of fossils, similar to
the single one sent to Mr. Conrad. In riding from the Ranch
house of Tejon to Fort Tejon, on Mr. Blake’s trail, Professor
Brewer and myself collected upward of _forty_ species of
mollusca in less than one hour, and without diverging ten feet
from our route!
The Californian Cretaceous formation is easily separable
into two main divisions. The older of these, designated in
the Report as “Division A,” is the equivalent of the upper
portions, Nos. 4 and 5, of Meek and Hayden’s section in
Nebraska, and the later beds of New Jersey and the Gulf States.
It is possible that this group may be separated hereafter
into two sub-groups; but that has no bearing on the question
at issue. The upper or more modern member, found overlying
the lower one conformably in various places, as about Monte
Diablo and at Martinez, has no apparent equivalent in America.
It is probably, however, the American representative of the
Maestricht beds, the ‘Danien’ of French authors. It is _not_ a
transition from Cretaceous to Tertiary, but is the most modern
member of the former formation.
It has many points in common with the Maestricht beds of
Europe. It contains but a single species, so far as known,
of the complex-chambered group of Cephalopods. A solitary
ammonite, represented by half a dozen specimens, has been found
by myself, in place, even to the very top of the formation.
Of 280 species of fossils recognized and named in the
Californian Cretaceous rocks, 107 are found in this upper
member. Of these, 84 are peculiar, and 23 are found in common
between undoubted members of this group and undoubted members
of the older group. Besides this, I was fortunate enough
to discover a locality near Clear Lake, this fall, where,
within a space of two feet, I found an admixture of upper and
lower forms, proving the existence of a transitionary bed or
perhaps group of beds. The following table will exhibit at
a glance the grouping of species at each of the principal
localities; showing at the same time which species are found
in the intermediate deposit, and which exist in common in both
the upper and lower divisions. The various localities are
designated by letters, as follows: M, Martinez; C, Clayton to
Marsh’s; T, vicinity of Fort Tejon; G, a locality 10 miles west
of Griswold’s near New Idria; I, New Idria; D, San Diego; LL,
Lower Lake Village, 1 mile S.E. of the town.

---------------------------+--------------+-------+-------------------
On studying the foregoing table, the following deductions
present themselves: 1st, that the rocks of the upper division,
at the various localities quoted, are all of the same
geological age; and 2d, that they are intimately connected
with the older groups by a passage of nearly a fifth of all
the contained species of fossils from this, either into the
intermediate beds, or into the lower group itself.
In anticipation of a possible objection that may be raised
here, it will probably be as well, before going further, to
state that in the Division B, there has been no confounding
of two groups. The same grouping of species extends to the
extreme upper limits of the fossiliferous rocks, which are
everywhere overlain by an immense deposit of non-fossiliferous
sandstones. Another objection, which has already been raised,
that the acknowledged Cretaceous fossils have become mixed
with more modern species by the breaking up and re-cementing
of an older formation, I shall not even attempt to refute. Had
such been the case, I would ere this, in common honesty, have
acknowledged it.
In support of the two conclusions arrived at above, we have the
following synopsis of the table:
Of the 107 species of fossils found in Division B, 44 are found
at Clayton, 67 at Tejon, 54 at Martinez, 22 at San Diego, 18
near Griswold’s, and 7 near New Idria. It is not intended
to be understood that these are all of the species found at
these localities; but that, up to the present time, these are
all that have been identified or described. Future work will
undoubtedly change the above figures.
Of the species found at the above localities, 50 are peculiar
to one or another locality; 29 are found at two localities
only, 14 at three localities, and 14 at four localities or more.
Taking the three typical localities, Martinez, Clayton and
Tejon, 21 species are common to Martinez and Clayton, 30 to
Martinez and Tejon, 25 to Clayton and Tejon, and 20 are found
at all three localities.
Now, having given what I believe ought to be considered
proof conclusive to any candid mind in support of my first
proposition, I shall endeavor to establish the second.
It will be seen that 16 species, found in the upper member,
also extend into the older group, Division A. In addition to
this, at the locality near Lower Lake Village, Lake County,
besides several species encountered for the first time, I
found 15 species in the same bed, within a superficial area
of two feet. Of these, 3 were previously known to be common
to the upper and lower division. Besides these 3, 7 of them
were common to this locality, and localities of Division B,
and the remaining 5 were, before this discovery, considered
peculiar to the lower member. One of these 5 is found in the
Mississippi Valley, in the “Ripley Group,” and another belongs
to a peculiarly Cretaceous genus.
As to the species found at the several typical localities,
independent of each other, and which would serve to show
their individual relations to the older formation without
corroborative evidence, Clayton has 10 species in common with
Division A, Tejon has 7, and Martinez 11. With the Lower Lake
bed, Clayton has 5 species in common, Tejon 5, and Martinez 6.
In glancing over Mr. Conrad’s “check list,” I find that out
of the 107 species found in his “Older Eocene of California,”
he has only included 74 in his enumeration. He has omitted
Callianassa Stimpsonii, Ammonites n. s., Nautilus Texanus,
Cylichna costata, Mactra Ashburnerii, Cucullæa Mathewsonii,
Nucula truncata, and Leda protexta; eight species, which
I mentioned in the Journal of Conchology, (Vol. 2, p. 88)
as being found in common in the two members of the Cal.
cretaceous, stating distinctly the localities in which they had
been found. At the same time he includes five other species,
from the same list, in his Eocene catalogue. Whether this
be carelessness, or an unfair avoidance of a difficulty, I
leave to others to decide. It is far easier to ignore such a
difficulty than it is to explain it away.
In regard to the distribution of the genera and species in
this and the associated rocks. All of the species are peculiar
to this group, or to this and _underlying_ rocks; _not one_
has been found associated either with living forms, or with
species known to occur in the recognized Tertiaries of
California. Five of the genera are peculiar to the Secondary.
An Ammonite ranges entirely through the group to the top of
the highest fossiliferous strata. The genera Perissolax,
Gyrodes, Margaritella, and the sub-genus Anchura, of the genus
Aporrhais, are all recognized as strictly characteristic of
the Cretaceous; so much so, that the presence of a single
undoubted representative of either of these genera would be
strong presumptive evidence of the Cretaceous age of any rocks
in which it might be found. On the other hand, the presence of
such genera as those in the list given below, would point to a
very modern era in the Cretaceous, to say the least.
It must be borne in mind that we have much to learn yet in
palæontology, especially in the matter of the vertical range
of genera. Every year we find genera, nay, whole families,
extending themselves beyond what had been fixed by previous
authors as their limits. A few years ago, the presence of
mammalian remains was considered characteristic of the
Tertiaries. Now we know of Marsupials in the Trias, and who
dare say that we cannot find mammals in palæozoic rocks? I
therefore maintain, that though we have here such genera as
Aturia, Typhis, Cordiera, Pseudoliva, Nassa, Mitra, Ficus,
Morio, Cerithiopsis, Cypræa and Galerus, still, the only
inference that can be drawn is, that the group is on or near
the verge of the formation, a sort of prophetic member,
presaging by some of its genera the formations to come, but
indissolubly bound by specific ties with the eras preceding.
[29] This species was referred by inadvertence to Div. B.
instead of A. This is the first time it has been found beyond
the limits of the lower member.
Prof. Blake stated that he considered the collections made by him, in and
near the Cañada de las Uvas, as not meager. There was a sufficient number
of species to make a quarto plate of figures.
Prof. Blake read the following notice:
Fossil Fish in the Great Basin, Nevada.
BY WM. P. BLAKE.
Fossilized fish are found in a light-colored clay shale, in
the mountains a few miles north of Silver Peak, a mining
district in the Red Mountain or Salt Basin region, about
one hundred and fifty miles south of Austin. The vertebral
columns, ribs and fins are very distinctly shown, and the
specimens are exceedingly interesting. They remind me of the
specimens from the famous locality of Mount Bolca, in Europe.
The specimen that I have here, does not appear to belong to an
ancient period, but I will not venture to refer it without
an opportunity of making comparisons, or submitting it to a
competent ichthyologist, which I propose to do.
COLLEGE OF CALIFORNIA, Nov. 19. 1866.
Prof. Blake also directed the attention of the Academy to specimens of
fossil vertebræ, collected by him in Tulare County. These specimens are
about twenty in number, and are from two to six inches in length, and
two to three inches in diameter. He believed them to belong to large
marine saurians, like crocodiles, but wished to make further study and
comparison previous to making a more formal communication to the Academy.
If correct in his opinion, it was, he believed, the first instance of the
discovery of saurian remains on the Pacific Coast of the United States,
and the discovery will be rendered still more interesting by the fact
that the remains occur in strata reputed to be miocene, associated with
sharks’ teeth and numerous marine remains, at least fifteen hundred feet
above the present ocean level.
Professor Whitney remarked that the remains of the crocodile, and
ichthyosaurus had been discovered on this coast by the Geological Survey,
and the fact published a year ago.
Professor Whitney read the following communication:
Notice of the occurrence of the Silurian Series in Nevada.
BY J. D. WHITNEY.
At a meeting of the Academy in May last, I gave some account
of the geology of the State of Nevada, with particular
reference to the age of the stratified deposits occurring
there, as determined from the collections of fossils brought
from that region to the office of the Geological Survey, by
J. E. Clayton, and various members of our corps. In that
communication I spoke of the probable future discovery of rocks
older than the Carboniferous or Devonian, in the mountain
ranges near Austin. This expectation has been realized, and
we are now in possession of a very interesting collection of
fossils, obtained by Mr. A. Blatchley, in the vicinity of the
Hot Creek Mining District about one hundred miles southeast of
Austin. This collection enables us to state positively that
both Upper and Lower Silurian rocks occur in that district, and
that they are well filled with fossils; not less so indeed,
to judge from the specimens received, than the strata of the
same age in New York, Ohio, Iowa, and Wisconsin, which they
resemble in a most marked degree, both lithologically and
palæontologically.
The fossils from the Hot Creek District are mostly weathered
out on the surfaces of thin slabs of bluish-gray argillaceous
limestones, and are crowded together in the same profusion with
which they have often been noticed by myself and others as
occurring in the Lower Silurian shales and limestones of the
Wisconsin Lead Region, around Big Bay des Noquets, and in many
other localities in the country bordering on the Great Lakes.
Both the upper and lower divisions of the Silurian appear to be
represented by the fossils of the Hot Creek District; but the
lower Silurian seems to be much the most prolific in fossils,
as is the case in Wisconsin and Iowa. The particular period
to which these lower Silurian forms may be referred is the
Trenton, including the Chazy, Birdseye, Black River and Trenton
limestones of the New York Geologists, and the Buff and Blue
limestones of the Western surveys. Nearly all the prevailing
types of the Eastern rocks of this age, are represented in
the Hot Creek collection, namely: Brachiopods, Gasteropods,
Cephalopods, Crinoids, Trilobites, and Corals; and there are
among them several of the most widely-distributed and most
characteristic species of the Lower Silurian. The following
have been identified: _Maclurea magna_, a characteristic Chazy
species, and _Pleurotoma lenticularis_, _Orthis testudinaria_
and _Chætetes lycoperdon_, all of which are abundant in the
Trenton limestone of New York, and the rocks of the same age
farther West. Among the fragments of Trilobites, two or three
different genera may be recognized, especially _Asaphus_, which
is represented by a species apparently new. There are also
fragments of crinoids or cystids closely resembling the species
figured by Hall, in the Palæontology of New York, Vol. I, as
_Echino-encrinites anatiformis_.
The rocks containing the above mentioned fossils crop out
in the sides of a deep cañon; and overlying them, at a
perpendicular distance of about a thousand feet, is a series
of beds containing numerous fragments of corals and crinoids,
silicified and weathered out from the surface of a bluish-gray
limestone, which I refer without much doubt to the age of the
Niagara limestone of New York. Among the corals, _Heliolites
spinipora_ and _Syringopora_ are recognizable; and among
the crinoidal fragments are stems of what appears to be
_Caryocrinus ornatus_.
With the exception of the Potsdam sandstone fossils,
described by Meek and Hayden as occurring at the base of the
fossiliferous series, in the Black Hills, no recognizable
Silurian forms have been observed by geologists, in the Rocky
Mountains, or anywhere to the west of them, unless possibly in
New Mexico. The Silurian Series, with the possible exception
of the Potsdam sandstone, seems to be entirely wanting in
the Rocky Mountains proper, the Black Hills being a sort of
outlier of the main ranges, and lying as far east as the one
hundred and third to the one hundred and fifth meridian. Dr.
Hayden says, in his paper, on the Geology and Natural History
of the Upper Missouri, published in 1862, that “hitherto no
indications of the existence of any other member (than the
Potsdam sandstone) of the Silurian period has been discovered
along the eastern slope of the Rocky Mountains within the
boundary of the United States.” He considers it probable that
the Potsdam sandstone is represented in the Rocky Mountains,
although no fossils of that member of the series has been as
yet discovered anywhere to the west of the Black Hills.
On the Mexican Boundary Survey, a few fragments of fossils were
found in the superficial detritus, near El Paso, (Longitude,
one hundred and six degrees) which indicated the existence of
Silurian rocks in that vicinity; but none appear to have been
found in place. Professor Hall remarks that “the specimens
referable to strata of this age (Devonian and Silurian)
are few, and they are in such condition as to give little
satisfactory information regarding the rocks in place.” The
specimens obtained are figured in the Mexican Boundary Report,
but not described, nor is their locality accurately stated.
Dr. Newberry, in his Report in the Geology of the Colorado
River region, refers the lower portion of the strata exposed
in the grand cañons of that river to the Devonian and Silurian
Series; but as no recognizable fossils were discovered by the
Ives’ Expedition from any rocks lower than the Carboniferous,
this reference can only be taken as expressing a conviction
based on lithological characters and stratigraphical
considerations.
In view of the above cited facts, it will be seen at once how
interesting this discovery is of undoubted Silurian rocks
west of the Rocky Mountains; and the more so, since we have
in this remote region a recurrence of conditions and forms
of animal life so closely allied to those with which we are
familiar in the States east of the Mississippi. It is a very
remarkable fact that these rocks have not been discovered in
the Rocky Mountains; and should farther explorations fail
to reveal their presence, it will throw a new light on the
history of the physical development of the central and western
portions of this continent. Taking into view what has now
been communicated, and what was stated in my previous paper
in regard to the existence of the older stratified rocks in
the Silver Peak District, it will appear that Dr. Newberry’s
generalizations were, in all probability, correct, and that
we may expect to find in southern and southwestern Nevada the
outcropping fossiliferous edges of the strata underlying the
Carboniferous of the great Arizona or Colorado plateau, and
that they will be proved to occupy an extensive area, and to
yield a profusion of organic remains.
Among the specimens collected by Mr. Blatchley, as also by Mr.
Clayton, Mr. Melville Attwood, and Dr. C. L. Anderson, and now
at our office, there is a considerable number which demonstrate
the existence of an extensive fresh-water Tertiary deposit in
Nevada. This formation, which belongs to a very late Tertiary
epoch, evidently occupies a considerable area, as our specimens
come from localities hundreds of miles distant from each
other. The existence of any marine formation more recent than
the Jurassic, in Nevada, has not yet been proved; but, as Mr.
Gabb obtained evidence, in 1864, of the occurrence of rocks of
Cretaceous age on Crooked River, in Oregon, east of the Cascade
Range, it is possible that this member of the series may yet be
discovered in Nevada.
All the fossils referred to in this and my previous
communication on the geology of Nevada, will receive, in due
time, thorough investigation at the hands of Messrs. Meek and
Gabb, or other competent palæontologists; and we expect that
our collections from that State will be largely increased
during the present year.
The death of the eminent naturalist, Dr. A. A. Gould, of Boston, was
announced by Dr. Gibbons.
