Those who dese to give their husiness a
wide circulation among reading and intelligent people, and especially among miners
and mill men, will do well to secure the advantage of the advertising columns of the
Mrytxo anv Screntiric Press. This paper
finds its way into our principal hotels, reading rooms, in all college and other schools,
etc., and hound volumes and monthly parts
aro fouud in the saloons of all the river and
ocean steamers. The paper is also received
by large numhers of scientific persons and
societies, and mining men in all parts of the
world More volumes of this paper are
bound for preservation and future reference
than of all the other periodicals on the Pacificcoast put together. Now is the time to
suhseribe and advertise. A glance at our
voluminous index for the past six months,
will afford the stranger to our columns a
very good idea of the character and variety
of the subjects discussed in this paper. It

Santa Ciara Conzecre.—The sixteenth
annual commencement of this institution
took place on Tuesday and Wednesday last.
The exercises were unusually spirited and
interesting. The various addresses hore
high testimouy to the excellency and thoroughness of the system of instruction pursued at this institution.
The first literary exercise was a critical
essay, by J. T. Rogers, entitled ‘‘ History,”
which evinced a marked degree of talent
and research. ‘* The Carhoniferous Epoch,”
by Jos. Wiley, was the title of another suhject, which was handled in a manner which
would have donc credit to even a professor
in the difficult science under consideration.
“ The Patriot’s Cry,” hy Joseph McQuade,
was a heart-stirring and well written poem.
“Mother,” an elegy, hy R. Gray; ‘“‘The
Equilibrium of the Three Kingdoms of Nature,” by A. L. Sage; ‘The Chinese in
California,” by T. A. Sutherland, spoken
hy James Hermann ; “‘'The Tax on Education,” by W. B. Murphy; “‘ Regicides,” by
A. Swecb, aud ‘ Our Martial Progress,” hy
C. ©. Arqucs, were each excelleut in their
way. The exercises contiuued three days,
and were interspersed with musi¢ and domestic entertainments. The degree of A.
M. was conferred upon 8S. A. Lyon, A. B.
Kirkup’s Patent Spike.
“We herewith present our readers with an
illustrated description of a newly inveuted
spike, to which we made a short reference
some four months siuce. The advantage of
such a means of securing rails to thet supports, especially on the dry plains of California, and the arid deserts botween the
Sierra Nevada aud Rocky mountains, must
be apparent to the most casnal ohserver.
Great difficulty is found in keeping the ordinary snake-headed spike in place in all
dry climates; but with a spike constructed
after Kirkup’s patent, it would seem that
this difficulty must be pretty effectually obviated.
In the illustration, Fig. 1 represents a
‘‘snake-headed,” and Fig. 2 a ‘‘roundheaded” spike, of this description. The
spike is split from its poiuted end in the direction of its length, and the two prongs
are beveled in alternate directions. When
the splke is driven into the sleeper the two
prongs diverge in opposite directions, the
chisel edge cutting the way for each prong,
aud the hevel edge throwing it outward.
With a 4% inch spike the prongs diverge
about 134 inches. It can be very readily
understood that a spike having the position
in the sleeper shown in Fig. 3 will retain its
hold against any casual displacement iucident to the jarring or tremhling of the rails
occasioned hy passiug trains, and the expansion and contraction occasioued by heat
and cold.
The American Artisan, in which this spike
was first deserihed and illustrated, says of it:
“We are informed that the saying in
weight of metal per mile over the ordinary

Sage and Jos. Wiley.

most flourishing and thorough institutions
of learning in the State.
We regret that our inability to be present

defect another year.
spike amounts to 1,750 pounds, and that
the power or weight required to draw a
‘‘snake-headed” spike of the above coustruction which is driven outside the rail,
is about 5,986 ponnds, andthe ‘‘roundheaded” spike, which is driveu through an
eye in the flange of the rail, ahout 7,656

does tho ordinary spike. The spike, however, can be readily drawn, and it requires
hut a hlow of a hammer to straighteu the
prongs, when it will be ready for use again.”
This invention was patented on January
2, 1866, by Launcelot Kirkup, of Brooklyn,
N. Y., and it has also been pateuted in the
principal European countries. The entire
invention has heen assigned to ‘‘The International Patent Bolt Machino and Split
Spike Company,” and any further information concerning if may be ohtained of the
President of tho company, H. A. R. Moénat,

Trae Hosmorpt Rrver.—Some considerable attention is being paid to the utilization of our interior rivers. If woare not
mistaken, a steamboat is already in process
} of coustruction for the navigation of the
.
upper waters of the Columhia river.
It is also thought that the Humboldt river,

which has its course altogether in Nevada,
may, at small cost, be made navigable for
nearly the eutire year; thus bringing into
cheap steam communication the eastern aud
western portions of Nevada. According to
alate number of the Owyhee Avalanche, a
party, desirous of testing its navigahle qualities, recently constructed a small boat near
the upper portiou of the river, and proceeded downward along its course. For
many miles the river was found to be two
and a half to six feet iu depth, but very
crooked and ahout sixty feet in width. The
character of the river is very uniform from
near its source to its mouth, with only ocsional rapids and shallows. To render it
navigable, two or three dams would have to
he removed, and a number of wing-dams
constructed to deepen the channel. On
approaching its mouth, the party could not
find a passage into the lake, owing to the rank
growth of the tules; yet it is said that an
outlet forty fect in breadth, opening into
the lake or sink is known to exist, and has
becu passed through hy settlers and Indians.

Ede, employed at the Royal Guu Factory
Department, Woolwich Arsenal, (Eng.)
Revised and enlarged from tho fourth
edition, by D. Appleton & Co., New York,
1867. For salo by A. Roman & Co., San
Francisco.
The above publication shows the work of
a practical mind. Myr. Ede is no mere theorist ; but is one who has a thorough practical knowledge of what he writes. The
title, ‘‘The Management of Steel,” does not
at all comprehend the full scope of the
work. The writer treats upon both iron
and steel, in nearly all their forms, conditious and manipulation. Thongh not ex. haustive, it nevertheless emhraces about
everything that is essential to he known to
the practical iron worker. It treats upon
the manufacture of iron and steel, the
choosing of steel for tools, annealing castiron and steel, hardening and tempering of
the same, oxpansion and contraction of
steel, shrinking of cast iron and steel, the
case-hardening of wrought iron, toughening
of steel for guns, shot, railway hars, etc.
This little work, of only 220 duodecimo
pages, will be found an inestimable treasure
to young mechanics who wish to make
themselves better acquainted with the materials upou which they work, and out of
which their tools are made. The importance of such information, hoth to young
apprentices themselves and the world at
large, can scarcely be estimated. Science
and the arts would thereby he advanced,
while the power of the head to contrive,
and the hand to execute, would be greatly
enlarged. YValuahle inventions would multiply, while those which perish at their
hirth, and see the light only to impoverish
instead of increase the wealth of the inventors, would be few indeed.

Of all the remarkahle applications of electro-magnetism, which have recently heen
made, perhaps the most extraordinary is that
of its introduction intoa mass of molten iron !
It is said that this experiment was recently
tested at one of the leading iron work estahlishments in Sheffield, with most unexpected results and success. The effect is
descrihed as surprising; the metal appears
to hubble and boil, while the perfect fusion
is much expedited, and the quality of the
iron greatly improved in toughness and
hardness. It appears that much of the impurity that remains after the ordinary process, is driven out by the action of the
magnetic current; hence it is inferred that
this new application of electro-magnetism,
may be regarded as full of promise in this
direction. It is to be hoped that further
particulars may soon be made public; and
in the meantime it is suggested that it is a
ease for the application of Wilde’s electromagnetic machine. If there is anything in
the alleged discovery, it would scem that
with the powerful currents therehy gencrated, the results must he proportionally
important. The accounts do not describe
the manner in which the current is introduced into the molteumass. Theinferenac,
however, would seem to be that the furnace
is isolated, and kept fully charged by a
powerful battery. Smee’s battery was used
. in the instance referred to.
