At the time of publication of this species, but a single

recent specimen had been obtained, and that was freed from the

epidermis. The statement that the shell was _hirsute_, was

founded upon the cicatrices observed upon the surface, Mr.

Gabb, who has recently returned from a trip to Mariposa, was

successful in finding a few specimens, by which the diagnosis

may be enlarged, and conjecture resolved into certainty. The

whole surface is covered with an epidermis, of a yellowish

brown colour, thickly studded with slightly curved rigid

hairs about one-twentieth of an inch in length. The animal

is of a reddish brown color, with the tentacles of a smoky

hue; tentacular sheaths darker than the body, which is small,

slender, finely granulated and unusually long and tapering

behind.

The shell bears the same relations to _H. Dupetit Thouarsi_,

Deshayes, that _Helix infumata_, Gould, bear to _H. fidelis_,

Gray. In the description of _infumata_, an important omission

occurs, owing doubtless to the imperfect condition of the type

specimen. In good specimens, all of the last whirl, except a

circle round the umbilicus, is covered with _very short_ and

thickly studded soft hairs, feeling harsh when dry, but velvety

to the touch when moistened.

Hab. Insula Sandwich, (Maui).

Shell perforated, left handed, elongately sub-cylindrical,

shining, reddish-brown, with painting of elongate, inosculating

black veins; whirls six convex, regularly (but slowly)

increasing; apex a little obtuse; suture moderately impressed,

not emarginate; aperture small, sub-ovate; lip acute; columella

white, short, almost straight, truncate, terminating by a

twisted plait passing within.

This species is more cylindrical than any of its congeners,

resembling most _A. Renyi_, Newc., which is longer, not

umbilicate, more pointed at the apex, with a twisted, not

truncate columella.

From _venusta_ and _citrina_, Mighels, it varies both in

form and color. With some varieties of _picta_ it claims

analogy only in the general plan of painting. Its striking

characteristics are its blunt apex, slightly rounded whorls,

small aperture, short and white columella, umbilicus, and

general plan of coloring.

A few specimens were collected at an elevation of 7,500 feet,

on West Maui, by the Rev. M. Alexander, to whom the species is

dedicated.

Description of New Species of Marine Shells from the Coast of California.

BY WM. M. GABB.

The following are a few of the shells collected by Dr. J. G.

Cooper, of the State Geological Survey, during his explorations

along the coast of this State. The specimens are preserved in

the collection of the Survey; most of them appear to be very

rare in a living state, though I have encountered several of

them in the later Tertiary deposits, especially in the Post

Pliocene.

Hab. Santa Catalina Island, 60 fms. Dr. Cooper.

This little shell looks not unlike the young of _Pleurotoma

Carpenteriana_, _supra_, but on a critical comparison, shows

several characters incompatible with such a reference; the

strongest of these is the peculiar shape of the posterior

sinus. In addition to this, the whorls of the present species

are much more numerous in proportion to the size, the first six

whorls of _P. Carpenteriana_ making a shell three or four times

the diameter of this one.

Earthquakes in California during 1864.

BY DR. JOHN B. TRASK.

FEB. 26TH, 0 h. 40 m.—A light shock of earthquake at San

Francisco. At 5 h. 45 m. a smart shock, having three distinct

vibrations. On the day previous, an “_Electric Storm_”

prevailed between Visalia, Tulare Co., and Los Angeles, which

was very violent in its effects on the telegraph lines.

On the 27th, a heavy “Norther” commenced and continued till the

eve of the 28th. This earthquake was felt at San José, fifty

miles south, at the same hour, and was marked by two very smart

shocks following each other in quick succession.

MARCH 5TH, 8 h. 49 m.—A smart shock of earthquake at San

Francisco. The earthquake began at the above hour. The first

wave was in a direction north and south, and lasted one and

three-fourths seconds. Nearly one and a half seconds elapsed

before the second shock, which occurred at forty-nine minutes,

three seconds past eight o’clock, and had a duration of one and

one-half seconds. The motion in this shock was rotatory.

Magnetism was _not_ suspended in this nor either of the other

shocks, this year. The total length of time included in this

earthquake, was nearly 5 seconds. These observations were made

at the height of 20 feet 4 inches above the ground, but persons

situated at a greater height felt the vibrations longer and

more severely.

We have brief details of this earthquake from Santa Rosa, at

the north, to Santa Cruz at the south, and from Stockton at the

east, for which we acknowledge our obligations to the Telegraph

Company. At Santa Rosa it occurred at 8 h. 50 m. the shock was

light. At Petaluma 8 h. 50 m., also light. At Stockton _about_

9 h., shock was severe. At Santa Clara 8 h. 40 m., the shocks

were very severe. The church spires waved to and fro, and the

earthquake is reported to have continued over two minutes, with

light vibrations between the heavier waves. At Santa Cruz no

time is given.

MARCH 10TH, 14 h. 8 m.—A light shock was felt in San Francisco.

” ” 16 h. 30 m.—Another shock at San Francisco, marked by two

distinct vibrations and lasting three and one-half seconds.

MARCH 20TH, 23 h. 45 m.—A light shock of earthquake having

four distinct tremors, and occupying a little more than three

seconds.

MARCH 22D, 13 h. 0 m.—A smart shock was felt at Stockton,

causing some little commotion.

MAY 20TH, 18 h. 1 m.—A light shock of earthquake at San

Francisco. At Stockton the shock was quite severe and occurred

nine minutes later. At San José it also was very sharp. At Napa

the earthquake, which was quite severe at this place, occurred

at 18 h. 57 m. At Sacramento the shocks occurred at 18 h.: and

was very severe. There were two distinct waves felt at this

locality. This earthquake was felt as far north as Long Valley,

in Mendocino County, and was followed by two loud reports like

artillery, almost instantly.

JUNE 6TH, 11 h. 7 m.—A light shock of earthquake at San

Francisco.

JUNE 22D, 20 h. 53 m.—A smart shock of earthquake at San

Francisco, consisting of three distinct waves and a profound

low rumbling sound. Each of the shocks were marked by a

peculiar abruptness, like sudden sharp jolts. They were

followed by a series of lessening tremors which gradually died

away.

This earthquake was felt as far north as Healdsburg, (about 80

miles distant), at Napa, at Pacheco, at Stockton, and at San

José, south of this city fifty-two miles, making a distance of

one hundred and thirty-two miles, north and south, over which

its influence was well marked.

JULY 5TH, 20 h. 3 m.—An earthquake at San Francisco, not

severe; this consisted of four distinct vibrations occurring

during a period of seven minutes. The second vibration and the

longest lasted nineteen seconds. The shortest vibration was six

seconds in length. The elapsed time between the waves varied

from forty seconds to one and one-fourth minutes.

JULY 21ST, 2 h. 7 m.—A smart shock was felt at San Francisco.

” ” 22 h. 40 m. 38 s.—A very smart shock of earthquake at San

Francisco, consisting of two waves at four seconds apart. The

direction of the motion was north thirteen degrees east. The

displacement was one and a fourth inches, at twenty feet four

inches from the ground. Pendulum suspension eighteen inches.

The earthquake was experienced at San José at the same hour,

and consisted of four strong shocks. At Stockton the earthquake

was severe, and took place twelve minutes later than at this

city. The earthquake was felt at Los Angeles, but was not very

heavy. No time is given from this latter locality.

JULY 25TH, 23 h. 56 m.—A shock of earthquake at Los Angeles.

AUG. 17TH, 22 h. 39 m.—A light shock of earthquake at Nevada

and vicinity.

AUG. 18TH, 5 h. 18 m.—A very strong shock of earthquake was

experienced at Grass Valley and Nevada, which threw down a wall

of stone and brick in the well of Dr. Fellows. This earthquake

was felt at Gibsonville at the north and at Marysville to the

west; at the latter locality it was twelve minutes later than

at Grass Valley.

SEPT. 6TH, 10 h. 3 m.—A shock of earthquake at San Francisco.

SEPT. 20TH, 11 h. 0 m.—A light shock of earthquake at San José;

it was observed at the Mission Dolores.

SEPT. 27TH, 10 h. 32 m.—A heavy shock at Mission San Juan,

Monterey Co.

OCT. 6TH, 21 h. 9 m.—A smart shock of earthquake at San

Francisco.

OCT. 14TH, 1 h. 8 m.—Two heavy shocks of earthquake were felt

at Mission San Juan, and another severe shock at 10 h. 25 m.,

the movement was from west to east.

DEC. 11TH, 20 h. 52 m.—A shock of earthquake at San Francisco.

This shock was felt at San José at 20 h. 51 m., and was

evidently more severe there than at San Francisco.

During 1864, we have had twenty-one days on which earthquakes

have occurred, and of at number there have been two days,

(March 10th and July 21st) in which more than one shock has

taken place within the twenty-four hours of each day.

The _British Colonist_, of Victoria, Vancouver Island,

furnishes the following statement:

From a gentleman who has resided on Vancouver Island for 15

years, we learn that slight earthquakes have occurred annually,

with one or two exceptions, during the entire period. Only on

one occasion (1858) does he remember experiencing a shock at

all approaching in severity that of Saturday morning, October

29th 1864. The oscillation, as on this last occasion, has

almost invariably been from west to east: and he accounts

for this, by supposing that the internal convulsion of the

earth beneath, has to find vent in the crater of Mount Baker,

situated to the east of us. This volcano has not had any

visible eruption for several years. On the last occasion, it

sent up a dense volume of smoke, and occasionally a bright

flame was seen to issue from the fiery furnace. Another old

resident informs us, that the appearance of the summit of Mount

Baker has undergone a material change within late years, giving

room for the conjecture that large portions have crumbled away

and descended into the yawning abyss of the crater which lies

between the two highest peaks.

Relating to earthquakes at San Francisco and its immediate

vicinity, we have an item of interesting information relating

to their effects at the Farrallones Islands, situated some

fifteen miles to the west of the city. It appears, upon the

testimony of the lighthouse-keeper at these Islands, and who

has resided there for several years, (seven or eight), that but

_two_ of the whole number occurring at this city, have been

felt at the Islands, and of these he made an official record.

The first was the shock of Dec. 23d, 1862, and that of June

22d, 1864.

From 1857 to date, we have seven years, during which time

twenty-five shocks have been authenticated at San Francisco,

while two only of the number have been felt at the above

locality west of the city.

New Mineral Oil Regions in the Tulare Valley.

BY WILLIAM P. BLAKE.

Recent examinations of prospecting parties, have added largely

to the well-known oil-bearing portions of the State. A district

some sixty miles in length, on the inner slopes of the Coast

mountains, towards the Tulare Valley, has been found to abound

in oil springs, or indications of oil. Oil exudes from the

surface in large quantities, and collects rapidly in small pits

sunk by prospectors. The soil about these pits is very black

and saturated with oil. The gases escaping from this soil are

inflammable, and many of the prospectors have been startled to

see flames spreading over the ground, beyond their camp fires.

In digging pits about these springs, large quantities of bones

of various kinds have been thrown out, and all are wonderfully

well preserved. These bones appear chiefly those of the horse,

deer, and elk, though there are many others which I have not

been able to recognize. The teeth of the horse, sent to me,

are of unusual size, and induce the question, whether they are

not of greater antiquity than the present race of horses. I am

assured that the variety of bones and teeth of many kinds is

very great.

The oil found gives an excellent article for lubricating

purposes, and must be very similar to the oil found near

Zanesville, Ohio, according to the descriptions given of the

latter.

Note upon the occurrence of Sphene in the Granite of the Sierra Nevada.

BY WILLIAM P. BLAKE.

Sphene, in small hair-brown or amber-colored crystals, appears

to be abundantly distributed in the granite of the Sierra

Nevada. It may be found at the sources of the American River,

in the exposures of granite about Slippery Ford, and other

points, and upon the Mokelumne River, further south. The

crystals are seldom more than the thirty second part of an

inch in diameter, and are not conspicuous, but may be found in

almost any specimen of the rocks.

It appears, that this mineral is also of common occurrence

in the granite of the British Islands. In a report to the

British Association, (1863) upon the composition of the granite

of Donegal, it is stated, that the rock contains, almost

universally, small crystals of sphene, in some varieties so

abundantly, as to induce the authors of the Report to term it

“sphene granite.” It is also observed that this mineral has

long been known to exist in the granite of parts of Scotland,

and in that of Galway.

Dr. Behr read the following letters from Major Preiss, of Mazatlan, as

to the efficacy of the _Euphorbia prostrata_, as a remedy for the bite of

the rattlesnake and venomous insects:

Euphorbia Prostrata as a remedy for the bite of venomous animals.

BY MAJOR EDWARD PREISS.

Mazatlan, January 7th, 1865.

...I send you herewith a sample of Gollindrinera, (Spanish,)

_Euphorbia prostrata_, (Linn.) It is found growing in the

territories of New Mexico and Arizona, in the United States,

and the provinces of Sonora and Sinaloa, in Mexico. In Jalisco

this plant is more scarce, and occurs mostly in a poor

condition.

It thrives in hard, sandy or stony soil, and therefore is most

frequently found on roadsides, in the streets of villages and

in house-yards. In Mazatlan I found a plant with branches,

measuring two feet.

It is a remedy against the bites of snakes and other venomous

animals.

During my voyage in New Mexico, I camped on the 5th of June,

1864, at noon, between Cubera and Pawate, near a waterhole. A

Pueblo-Indian approached me, and entered into a conversation.

He could read and write Spanish, and was very well versed on

the map of the country. Noticing a snake in the waterhole, I

asked him whether there were many rattlesnakes in those parts,

to which he gave an affirmative answer. On questioning him

whether Indians frequently died from snake-bites, he answered:

“No, as they have an antidote against the poison.” At my

request, accompanied by a gift of some cigarritos, he brought

me a plant, which he gathered from the roadside, and which he

called “Gollindrinera.” He told me that nobody ever died, not

even from the bite of a rattlesnake, if this plant was applied

in time. At the same time he told how it was used.

In Mexico I also found the country people well acquainted with

the property of this plant. They apply it when their domestic

animals are injured by venomous amphibia or insects.

The branches and roots of this plant contain a quantity of

a milky sap. This is obtained by pounding and squeezing the

plant, and is given to the patient in doses of about one

drachm. The remaining fibres of the pressed-out plant are

externally applied on the wound. The dose is repeated every

hour,—or in aggravated cases, every half hour,—until the

patient feels relieved; which will occur in a few hours. The

external application must be frequently renewed.

I ascertained from reliable authority, that two dogs, being

bitten by rattlesnakes, were cured, one after four, and the

other after six repetitions of the dose. The poultice was

frequently changed. Both dogs were perfectly restored within

twenty-four hours.

Tepic, March 28th, 1865.

...Myself and companion arrived on the 14th of March, 1865,

at 3 o’clock P. M., at San Blas. In the evening, our faces,

necks and hands were badly bitten by myriads of sandflies. The

sting of these flies is exceedingly painful, and the effects of

them last for several days. Every person visiting San Blas will

not easily forget these insects; each sting produces a reddish

swelling, which hardens after awhile, and sometimes remains for

eight days and more. We left San Blas on the 15th of March, at

1.30 A. M., and arrived at 5 P. M. at Tepic. The fly-bites were

excruciatingly painful. On the 16th we used liquid ammoniac to

allay our suffering, but without result. In the forenoon of

the 17th I found two small Gollindrinera plants in the streets

of Tepic; I pulled it, roots and all, from the ground, broke

them into several parts, and rubbed the milky juice over my

sores. In half an hour all the pain had left. Not being able

to find any more of the plants, my companion had to suffer for

several days longer; which proves, however, that my relief from

the tormenting pain was directly to be credited to the medical

virtue of the Gollindrinera.

During my lengthened stay among the natives of Australia,

I observed that no black man ever died from the bite of

a venomous reptile,—excepting always the dead-adder,

(bothrops)—while a white man seldom escaped death. The remedy

of the blacks is very simple, consisting merely in sucking

out the wound, and in keeping awake the patient for at least

twenty-four to forty-eight hours. The dead adder (bothrops)

of Australia is probably the most poisonous reptile. A black

man, if bitten by this snake, will be abandoned to death by his

friends, they being sure that help is out of the question. I

witnessed once the death of a victim of the dead-adder.

I read in an Australian paper, that a white boy, who was bitten

in the finger by a dead-adder, had so much presence of mind, as

to chop it off with his pocket-knife. The finger had afterwards

to be regularly amputated, but the boy’s life was saved.

An interesting discussion occurred as to the characteristics of various

species of trees.

BY PROF. W. H. BREWER.

I find in published _Proceedings of the Academy_, just

received, that some remarks I made at the meeting of October

3d, 1864, were not published, that I wish recorded.

In the discussion on the occurrence of fossils in the

auriferous rocks of California, I stated that fossils had been

found by the Geological Survey, in the rocks associated with

gold, along a line nearly 300 miles in length, extending from

Pitt River to the Mariposa Estate; that the associated rocks of

similar age, bearing gold, had been traced upwards of 550 miles

in the Sierra Nevadas, and that _Jurassic_ fossils had been

found in the “auriferous slates,” along a belt of 200 miles of

this distance, and that both _Jurassic_ and _Triassic_ fossils

had been found in considerable numbers near and in Genesee

Valley, Plumas Co.

Mr. Hubbard presented the following paper from Mr. W. H. Pease, of

Honolulu:

On the existence of an Atoll near the west coast of America, and proof of

its elevation.

BY W. HARPER PEASE, OF HONOLULU, H. I.

Having read an interesting paper by Dr. Blake, in a late number

of the _Proceedings California Academy_, on the proofs of a

recent elevation of the coast of California, it occurred to

me that I had in my note book, information unpublished on the

same subject. As it lies within the field occupied by your

Academy, I furnish it herewith for publication. My information

was gathered from a Journal kept by Lieut. Griswold,[11] (a

young gentleman of scientific taste, and a close and accurate

observer,) during a cruise off the west coast of Mexico, in

search of guano. Among the islands visited, was “Clipperton

Rock,” which is the locality I refer to.

Before giving any extract, I will state what was known of the

island.

It is situated in Lat. 10° 17’ N., Long. 109° 19’ W., and was

discovered by Capt. Clipperton, in 1705. He appears to have

sighted only the tall volcanic rock, which stands near the

south end of the island, and passed on without learning of the

existence of the island. It appears not to have been noticed

again for more than a century, so that its position, and even

its existence was doubted.

The only published account of its having been visited

since, are those by Capt. Benj. Morrell[12] and Sir Edward

Belcher.[13] The former called there during a sealing voyage,

in 1825, and gives a meagre account of it in a few lines,

remarking, that “it produces a little shrubbery and some coarse

grass, among which, I think, fresh water might be found by

digging. Among the few vegetable productions of this island,

we found a plant resembling sarsaparilla, which badly poisoned

several of the crew who handled it.”

Sir Edward Belcher, during his surveying expedition, wishing

to verify the existence and position of the island, searched

and found it. He did not land, but gives the result of his

examination from the mast-head. With other remarks, he states

that “it is a coral lagoon island, three miles long N. and

S., and the same E. and W. There are two entrances, both on

the weather side, which at high-water may be safe, but at the

moment we passed, the surf was too heavy and the reflux showed

the rocks bare. On the beach several large trees were observed,

but no living trees were seen.” (May 8, 1839.)

Lieutenant Griswold notes in his journal, as follows: “On the

6th of August, 1861, we lay on our oars, just outside the

breakers on the N. E. side. At half past six we were ashore,

shooting in on a high roller, which left us high and dry upon

the beach, with a hole stove in our bow. The beach was covered

with drift wood, and while the crew were collecting it, I

started to examine the island.

“Upon every side it is girdled by a broad barrier of coral,

about fifteen feet above the level of the ocean. There is no

entrance to the lagoon, neither does it communicate with the

ocean by subterranean passages, as the water inside is _fresh_

and _potable_. It is slightly brackish, but will appease

thirst. The ‘ROCK’ is a ragged pile of volcanic formation, on

the south end of the island, gray and splashed over with the

deposit of the birds. It is cracked and split in every possible

direction, here and there shooting into tottering pinnacles.

As you wander through the caverns and clefts, with which it is

perforated, there is an incessant splashing and dropping of

water. On the very topmost pinnacle, which I reached after

a hard climb, I found a little basin containing a couple of

buckets full. The caverns were dreary looking places, dark and

wet, and echoing to the hoarse cries of the sea-birds. The

rock, on its sides, is rounded and smoothed by the action of

the waves, at some long past time, and in many places ‘_the

walls are crusted with coral_.’

“The highest pinnacle of the rock is about 120 feet high, and

it covers, I should think, about two acres. It stands on the

edge of the lagoon, or rather within it, being connected with

the coral barrier only by a narrow isthmus of coral clinker.

Between this rock and the sea, however, the barrier, instead of

being as elsewhere, a solid platform of coral, is only a heap

of fragments, piled in winrows by the waves, 250 or 300 yards

in width. The lagoon is a quiet fresh water pond, two miles

long and about one broad, with a long spit of mud running out

into the middle of it, but elsewhere of a light green color,

which seemed to indicate a considerable depth. Its shores are

abrupt, the coral platform in most places projecting out over

water of a considerable depth. I did not find the least sign of

vegetable life upon the island.

“The only plant[14] seen, grew in considerable quantities in

the lagoon, which I pulled out of the water, where it was

growing. There is nothing but a coral platform, coral clinker

and coral sand. We found nothing to detain us and left the

island on the afternoon of the day on which we landed.”

Mr. Darwin, on his remarks on the geographical distribution of

reef-building corals, states that he could find no evidence

of their living on or near the west coast of America, and

consequently discredits the statement made by Sir Edward

Belcher; for after examining a Ms. chart of Clipperton Rock,

at the Admiralty Office, drawn by Sir Edward, came to the

conclusion that it was more of the shape of a crater. The

Island is, however, a true Atoll and has been elevated at least

100 feet.

It must have been closed since 1839, and the freshening of the

water has probably been caused by rain.

We may also add, that it stands within the limits of reef

building corals, as deduced by Mr. Dana, from tables of the

temperature of the sea, and consequently is confirmatory of his

opinion.

We might add other facts in support of Mr. Dana’s theory, but

from other parts of the Pacific.

Eight members present. Prof. John Torrey, R. Kennicott W. H. Dall, Horace

Mann, and Capt. Wright, visitors.

Donations to the Cabinet: A collection of Rocky Mountain plants, by Mr.

Bolander.

General discussion as to the motions of the Flying-fish.

Remarks by Mr. Kennicott and Dr. Behr upon the relation of the Esquimaux

to the North American Indians. Dr. Behr stated that the Esquimaux could

be considered only as a kind of Indians, their language being of the same

structure, and their different habits were owing to physical influences.

He further stated, that the Esquimaux lived formerly farther south. Mr.

Kennicott remarked, that from his observations and information derived

from Madam Roshkin and from St. Zagoshins’ Report, he believed the

natives, for some hundreds of miles up the Kvichpak or Yonkon River, were

Esquimaux rather than Indians.

Dr. Torrey stated, that he found on a trip to the Yosemite Valley, a

plant that he described twenty years ago, and which he had not since seen

in the collections examined by him. He named the plant, finding it to

be a new genus _Kelloggia_; the plant is quite common in the valley and

vicinity, and belongs to the family of Rubiaceæ; the aspect of the plant

is, in regard to its ramification, much like that of a _Galium_, while

its leaves and their arrangement resemble an _Epilobium_. It was first

discovered by some member of Com. Wilke’s Expedition, somewhere along or

near the Sacramento River.

Dr. Torrey also stated that he found _Sarcodes Sanguinea_, (Torrey), the

Snow-plant of the Californians, to be apparently indifferent as to what

plant it fixes itself or derives its nourishment from; he found its fibre

penetrating into the root of a _Rumex_, and not as has been supposed into

the roots of _Sequoia gigantea_. He also spoke of the great beauty and

fragrance of the California White Lily, (_Lilium Washingtonianum_,) and

of its being quite common in the vicinity of the Yosemite Valley. Its

habits are much like that of the common white lily, (_Lilium candidum_).

This evening, at 7 o’clock, a magnificent rainbow was observed, the

colors of which were unusually vivid.

Dr. C. T. Jackson read the following paper, relative to the Big Trees of

Calaveras County.

MEASUREMENTS OF THE HEIGHT AND CIRCUMFERENCE OF TWENTY-FIVE OF THE “BIG

TREES,” (_SEQUOIA GIGANTEA_,) IN CALAVERAS COUNTY, BY DR. CHARLES T.

JACKSON AND MR. JOSEPH B. MEADER, AUGUST 2D AND 3D, 1865.

Instruments made use of:—

1. Sir H. Douglass’ Reflecting Semicircle; (Cary).

2. A Reflecting Level; made by J. H. Temple, of Boston.

3. A common Measuring Tape.

The horizontal point was fixed upon each tree, and the angle

measured by the Reflecting Semicircle, and protracted by it.

The circumference of the trees was measured above the swell of

the roots, about six feet, where the stem takes its proper form.

Several measurements, originally made with too high an angle,

were taken over again with a longer base, so as to avoid the

error of refraction in the glasses of the mirrors.

We trust, therefore, that the following measurements will be

found to be correct.

Mr. Bolander submitted a paper on the Grasses of Arizona, with the

following remarks:

The following List of Grasses, accompanied by the very

judicious and practical observations of the Corresponding

Member of our Natural History Society, Mr. C. J. Croft, of

the 1st Cavalry California Volunteers, was received by mail

from Fort Goodwin, Arizona Territory, some little time since.

From the same intelligent source, we have, from time to time,

received many valuable specimens, preserved with uncommon care,

and reaching us in a state quite unusual, even from localities

far more favorably situated. We are very hopeful, we shall

shortly be placed in possession of specimens of the seed of

the _White Layia Mexicana_, for ornamental culture, as also

of a species of native Potato, from the same indefatigable

individual, who has also furnished us with a very interesting

account of numerous species of the Cactus family, of that

District.

The Grasses of Arizona.

BY C. J. CROFT, U. S. A.

The grasses of this Territory, principally consist of four

varieties:

No. 1. (_Pleuraphis Jamesii_, Torr.,) is the lowland Grama

which grows in great profusion along the valley of the Gila,

and constitutes the principal feed for our animals, which do

quite well upon it, moderately worked.

No. 2. (_Aristida purpurea_, Nutt.) The highland Grama, growing

upon the sand “mesas,” or highlands, seems to differ but

little, if any, from that found in some portions of California.

No. 3. (_Muhlenbergia pungeus_, Thurb.) Black Grama, or, “Grama

China,” as vulgarly called by the natives, is the most valuable

as feed; upon it animals will fatten. It grows on the highlands

in sandy arid soil. I have never met any of this variety in the

valley of the Colorado, and but very little in the territory of

New Mexico. At this post we have had as many as 700 animals,

and the scarcity of forage required us to herd our stock upon

this grass during the winter. We were often obliged to make

rapid and distant marches in pursuit of Indians, over a country

almost impassable, yet our horses stood it well, fed only upon

this grass. Our cavalry here had no grain during the entire

winter. This Grama, like the other species, grows in bunches

several feet apart, and the lower stalks are green during the

winter season.

No. 4. (_Sporobolus airoides_, Trin.) This grows in the

valleys. A great portion of the Gila Valley is covered with it.

Animals eat it readily when green; it is however a powerful

diuretic. As a winter grass it is of no account.

Besides these four enumerated grasses, the letter contained

three others from the same locality:

1. _Panicum capillare_, L.

2. _Tricuspis pulchella_, Kunth.

3. _A Poa_, much of the habitat of _Poa sudetica_. Vivid

green; leaves plane, rather large; spikelets four-flowered,

oval; lower glume one, and the upper three nerved; lower palea

distinctly three-nerved, scabrous on the Red nerve. The nerves

of the glumes, as well as of the lower palea, are of a vivid

green color, and exceedingly prominent. The whole aspect of the

plant sent, would rather suggest that it is not indigenous to

that section of the country.

Note on the abundance of Iron Ore in Northern Arizona.

BY WM. P. BLAKE.

In 1863 I observed an iron formation of considerable extent

and interest upon and near the William’s Fork of the Colorado,

near its mouth. The ore is chiefly the micaceous variety of

Hematite, or “specular iron,” and occurs in thick beds and in

thin sheets, in a ferruginous limestone or dolomite, evidently

metamorphic, and tilted up at a high angle.

It forms a belt of peculiar appearance, that may be traced

by the eye for miles across the country, in a direction

a few degrees south of west. This rock and iron ore is

inter-stratified with chloritic and talcose slates and granite,

and the series also bears copper ores and gold.

From the collections made by Lieut. Whipple’s party, in 1853,

in the mountains north, it would appear, that similar rocks

exist in the Cerbat and Aquarius Mountains, the extreme

geological antiquity of which, was commented on by me in the

Pacific R. R. Reports, Vol. III, p. 59. It is possible that

this ferriferous formation is connected with the extensive iron

formation of the coast of Mexico, south of Acapulco, described

by Mr. Manross, (Am. Journ. Sci., XXXIX, 358,) and it may be of

pre-Silurian date.
