Our Water Supply.
There are several bills now before the
State Legislature, providing for the introduotion of water into this city, or perhaps
wo might rathor say, for the payment of
“‘mnch monies” for its introdnetion. For
none of these bills, aa far as wo can learn,
affords any guarantees that we shall really
geta sufficient supply of a good artiole.
We are told merely that, on furnishing the
money asked for, we shall be provided with
a certain amonnt of a liquid of whose
qnality wo know nothing, while for the
completion of the contract on the part of
otbers, we have only onr general faith in
mankind to rely upon.
Before the money of the people is voted
away, the tax-payers onght to have good
evidence that it will be pnt to the best use.
We have a right to demand information as
to the nearest place whence we can obtain
an abnndance of pure water for years to
come, We onght to be shown first,
whether this peninsula will oontinne to
afford such, as it becomes more thorongbly
tilled, in qnantities which will suffice for
her increasing population. If tbere is
danger of impnrity caused by tbe increased
amount of land brought nnder cultivation,
or if the snpply will in time be too small
for thefarmers and for the city, tben we
onghtto know where we oan get what we
reqnire.
The proper way to act, it seems to na, is
to have a commission appointed, say by the
Mayor, to examine the matter and to report before decisive action is taken. Let
the supply qnestion of the peninsula be
settled finally. When it is known that we
ars in earnest, we sball soon get a fair
knowledge of our water resources, and oan
determine, to the satisfaction of the people, what is best to be done. Let engineers
of bigh standing, who bsave a repntation at
stake, be appointed on the commission, and
we shall then be able to go to work with
onr eyes open. But for heaven’s sake let
us have no blind and hasty legislation.

Avrora and Storm.—Tnesday night,
between 11 and 12 o'clock, the sky was
illuminated by a most brilliant red light,
which caused several persons to start
ont in searcb of the burning building.
Wednesday morning abont four o’clock we
were visited by a brisk storm and snch
thunder and ligbtning as has seldom if
ever been experienced within the memory
of old residents. The gas lamps throughout the city were extinguisbed, otherwise,
no damage done.

that the universe is a succession of cycles

Sanozxr’a Brun for the sale of placer
mines has passed the Hous of Representatives,
Jackson's Patent Oscillating Wagon.
In tbe present age of the world we are
continually introducing measures for
smoothing the pathway of life. New
methods of creating comfort and pleasnre
are being continnally invented. Our
honses are more Inxurions, our garments
the same direction, or, in other words, that
what is really for one’s private advantage
is also for the benefit of somebody or something else; the reality of which truth is
every day becoming better exemplified.
We give this week an illustration of an
invention which promises increased ease
and comfort for botb man and horse. It
finer, our food better than ever before. is an ingenions improvement, whicb perEspecial advances have been made in the)
oonvenience of traveling, and a ride of seyeral tbonsand miles across tbe continent is
to many a real pleasnre trip. So, too, we!
mits of application to all kinds of wagons,
trncks and otber vebioles, and is especially
important for those without springs. It
consists in securing the axle to the body of
SAMUEL JACKSON’S PATENT OSCILLATING WAGON.
are improving our roads and streets, using
superior pavements, and in other ways rendering lighter the labors of the dumb creation while we increase our own comfort.
And, in this connection, we are reminded
how, whbile adding to our personal convenience, we are led to give more beed to the
claims of bumanity, and to see more clearly
pow it advances our private interests to
look more closely to the welfare of the
animals whicb toil for us. Indeed, it is a
wonderful provision of Providence which
pas so constituted affairs that our selfish
desires and our nobler impulses both tend in
the vehicle by movable attachments placed
below the axis of the wheels. Crank axles
or straight axles, with bars or arms, or any
other contrivance by whbicb the object can
be obtained, may be used,
In Fig. 1 is sbown a carriage witb the
improvement (with orank axles) attached.
In Fig. 2is sbown the method by which
this attacbment ismade, Here the springs
are at rigbt angles to the axles; but the position of the springs may be varied without
affecting the principle in any way. The
ordinary journal upon which the wheel
runs is denoted by A. B is the box attacbed to the lower part of the spring in
the manner shown in the engraving, or in
any otber manner specially applicable to
the partioular vehicle upon which it is desired to put the improvement. C is the
jonrnal wbiob works in B.
The motive power being applied above
B, when it is first brought into reqnisition
in starting the vehicle, the load is swnong
forward of the axis of tbe wheels, giving a
lighter draft and easier motion than is obtained in the common way, while the oscillation of the wheels will ease every part of
the vebicle, and relieve tbe borses of the
jerks and strains so common to all fixed
axles. This oscillation has been tested by
weigbts, over an obstruction, on 4 model
with wheels eleven and twelvo inohes in
diamoter. The crank of the axles was 1%
inches, tho obstruction 1% inches high,
and of sufficient length to chuck the front
wheels. To draw the model over the obatruction, there was required a draft of
eight pounds with fixed axles, and of six
pounds with oscillating axles, giving a positive gain of two pounds, or twenty-fivo per
cent., witb these last. The greater the obstruction the greater is the oscillation, and
the greater the gain, other things being
equal. On smootb, level gronnd, the oscillation is smaller, and on nneven, beavy
or sandy roads, the gain is greater, where
it is most needed.
A wheelbarrow with this improvement,
with a wheel 19 inohes in diameter, the
orank 4% inches, when passing over an obatruction 2% inohes bigh, required a draft
of 19% pounds, With a fixed axle, 33%
ponnds were required, showing a gain of
considerable more tban a third where this
devics was used. Had the wagon, in the
oase given above, bad the same proportion
between crank and wheel, it would bava
had a proportionate gain.
The improvement thus offers the advantages of less power required, and henoe a
possibility of greater speed if necessary, of
greater ease, and of less violent shocks,
and, therefore, of greater durability of the
vebicle. The inventor has at his place a
full-sized wagon with the improvement,
whicb may be inspected and tested. For
furtber particnlars address Samnel Jackson, No, 149 High street, Newark, Essex
county, N. J.
We made mention in our summary, at
tbe time, of the settlement by compromise
of the dispute about title between the Pogonip & Othello and the West Point
mining companies at White Pine. The litigation lasted a year, but finally the parties
came to terms, the West Point Company
gaining largely by the settlement. This
was brought about ina large measure by
Mr. Robert Barton, Superintendent of the
latter company, and to his perseverance,
energy and ability, his company are heavily
indebted.
Quaris ror Nevapa.—Mr. BR. N. Riotte,
acoording to the Reese River evetlle, has
had 4 number of California quails taken
into that neighborhood to be turned loose
for propagation. The ides is an excellent
one. ‘There is every reason to believe that
bird will flourish there, if the bunters
will let it alone for a few years. We trust
there may be others in various sections of
tbe wide State of Nevada wbo may be induoed, by this example, to manifest a similar degree of publio spirit.
