plvre rises nbove us with its cathedrul dome
nrching toward hicaven, of which it is the most
perfect synonym and symbol. It floats around
uz like that, grand object which the apostle
John saw in his vision—‘a sea of glass like
unto a erystal."’ So massive is it that when it
hegins to stir, it tosses great ships like playthings, and sweeps eity and forest like snowflukes to destruction before it. And yet it
is so mobile that we have lived for years in
it before we eun be persuaded that it exists
at all, and the great bulk of mankind never
realize the truth that they are bathed iu ao
ocean of air. Ita weight is so enormous
that iron shivers beforo it like glass, yet a soap
bubble sails through it with impunity, and the
tiniess inseet waves it aside with his wing. It
ministers lavishly tu nll our senses. We tonch
it not, but it touches ns. Its warm south wind
brings back color to the pale face of the inyalid; its eool west wind refreshes the fevered
brow und nukes the blood mantle to our
cheeks ; even its north blast braees into new
vivor the hardened children of a rngged cltmate. ‘The eye is indebted to it for all the
magnificence of sunrise, the brightness of midday, the chastened radiance of the morning,
and the clouds that eradle near the setting
gun. But for it the rainbow would want its
trinmphant areh; and the wind would not
eend its fleecy messengers on errands around
the heavens; the cold ether would not send
snow feathers onthe earth, nor would drops
of dew gather on the flowers. ‘The kindly
rain would never fall, aor hail-storm nor log
diversify the face of the sky. Our naked
globe would turn its tanned and unshadowed
forehead to the sun, and one dreary, monotonous bluze of light and heat dazzle and burn
up all tbings. Were there no atmosphere, the
evening sun would in 2 moment set, and without warning, plunye the earth into darkue:s.
But the air grasps in her hand a shield of his
Trays, and lets them slip through her fingers so
that the shadows of evening are gathered by
degrees, and the flowers have time to bow
their heads, and each creature space to find a
plaee for rest, and to nestle to repose. In the
niorning, the garish sun would at one bonnd
burst from the bosom of aigbt and blaze above
the horizoa; but the air watenes his eoming, and sends first but one little ray to another, and then a handful; and so gently draws
aside the eurtain of nigbt, and slowly lets the
light fall on the face ol the sleeping earth, till
her eye-lids open, and like a mun she goes forth
again to labor until evening.

TANGENTIAL TURBINE WATER WHEEL,
The annexed illustration represents what is
known as the tangentiul turbine, or hurdyguidy water wheel, with a reaction guitle,
whereby the water having onco impinged upon
tho buckets of the wheel, is mude to react
. upon succeeding buekets nntil the force of the
1ush ol water is eutirely exluusted, eo that it
drops quietly from the wheel by the mere foree
of its gravity. The construction of the wheel
may be distinetly seen iu the engruving. The
water is seen to rush in, through the conducting pipe, with a veloeity and impulse due to its
head. After striking the buckets and passing
into the inner side ol the eireumference ol the
wheel, it will be observed to be so directed in
its motion as to avain receive an upward direetion, striking the buckets at a poiot below
tbe place of first contaet, when it imparts the
85 drops per rite. aud LL ineles each drop.

it will run a mill of 20 stamps, each 650 pounds,
85 drops per ininute, and 11 inches eaeh drop.
The wheel is furnished of different sizes to suit
the wishes or necessities of the purchaser.

Borrion rrom Gop Hint.—The Gold Hill
News says: “The amount of bullion shipped
from the Gold IIill Express office, for the
snonth of March last, amounts to $590,123.89.
For the quarter ending March 3lst, 1866, the
shipments reached $1,397,659.70! ‘I'bus, it is
manifest that uo less than five millions of raw
silver and gold will be dug out and exported
from this little burgh during the year 1866.

TANGENTIAL TURBINE WATER WHEEL.
whole of the power remaining in the water
after its first impulse.
The wheel is now ia successful operation at
Hydliff's Mill,in You Bet; atthe Empire
Tunnel Company, French Corral; at the Croasus Silver Mill Company, Kearsage; at the
Clear Creek Company's Mill,in Tulare county,
and other places. It gives a high percentage
of work for water eonsumed; is exceedingly
simple in its construetion, and eosts bnt little,
in comparison to most water wheels. It 1s particularly applicable for high falls, and where the
water caa be eonveyed along and down mountain sides, by means of pipes, as in hydraulie
mining. ‘The wheel is manufaetured at the
Miners’ Foundry in this city. A wheel eight
feet in diameter eosts but $500, and is estimated to be capable of performing the following duty: With—

Ax Ixrernatinc Facr.—During our reeeat
visit to the inines of Grass Valleyand Nevada,
a very interesting fact cme under our notice,
to the effect that all the distinetive features
which are so observable in the mines for the
first 150 or 200 feet in depth, disappear beyond thut depth, and that the veinstoae
thereafter presents a nniform eharacter; so
much so, that when speeimens from the lower
levels of the deepest mines arn thrown together
promiscuously, it is almost impossiole to distinguish the one from the other. On visitiug the
Sneath & Clay mine, at Nevada, we fouad the
same eharaeteristie to prevail; the veinstone
of that miae being quite indistinguishable from
that from aay of the deep miacs of Grass Valley. The solitary exception notieed is in the
Norambagua, below Grass Valley. The only
miae, we believe, in Nevada eounty earrying
apy aotieeable quantity of arsenical pyrites.
Great Britain alone produces ode-third of
all the iroa product of the world.
Sopium Amatoam.—Our readers will find a
very interesting letter on the eecond page nf
the preseut issue, in relatinn to the discovery
of the use of sodium amalgam in working gold
nres, ‘The letter contains a brief aecount of
tho discovery and the most eesential portion of
the specificutions of the patenten. It will be
seen that among the udvantages ctaimed for
the amalgam is that of faeility of packing nnd
transporting the solid amalgam. In this connection, we would etate that two or three experiments, of whieh we are eognizant here,
would eeem to iudicate that when this solid
amalgam is expoeed to the aetion of the air,
the sodium gradually oxidizes, and the solid
soon melts into a liquid mase, enrrounded by
eaustie soda. If there is not some simple
means of preventing this aetion, it will bn impoesible to transport mercury thus, in the eolid
state, witltont packing it in nir-tight vessels.
We should be glad to know bow Mr. Wurtz
ohviates tbis difficulty. Further ond careful
experiments are needed, and many points conneeted with the application and nse of the
sodium amalgam. It is a subject that well deserves to be thoroughly and practically investigated, and we shall be happy, at any time, to
reeeive and publish the results of careful and
reliable experiments in relation to it.
Tue Union AmaLoasator.—We would call
the attention of millmen, and others, to the
advertisement of the Union Amalgainator,
whieh appears in our columne to-day. But little effort hns heretnfore been made to introduee
thie pan to public notiee; yet all whn have
used it, so far as we have learned, unite in pronouneing it highly effieieat, both ae an umalgamator and as a triturator. It is so eonstructed as to be rua with great speed, presenting a double grinding surlace, revolving in
opposite directions; whieh motion effeets a
thorough mixiag of the pulp. and admits of n
speed three or four times ae rapid as pans
where the motion ie single. By this arrangement great eeonomy in weight of metal, cost
and epace is secured. It is probably more
readily and easily eleaned up than any pan ia
use. It may be seen in operation every day
at the San Francisco Foundry (Devoe, Densmore & Co.}, eoruer of Mi-sion and Fremont
streets, Millmen and others interested iu euch
machinery visiting this eity, will do well to eull
and examino tbis pan and witaess its operation at the place above designated.
Tue Sranparp Soap Co., of this city, manufaeture a most excellent article of washing
powder, said to excel anything of the kind in
use; and toeontain nothing that will injure
the finest fabric. It also possesses the merit
of working equally well in either hard or soft
water. It is mueh more eonvenient for uee
than soap, either hard or soft. Itis for sale by
the grocers generally, sn that a trial of its virtuee may readily be made by any one deeiring
tn do sn. See advertisement in another
column. :

often. Another letter from our regular correspondent “D.” next week. “O,. W. E.” and
