WINING AND SOTRENTIFIC-PRESS4). The principal mass
of ore (a, ¢,) lies in the
direction of the argillaceous slates of which the
mountain is made up.
At the depth of about
400 feet, it sends off a
branch (6), which dips
at a considerably less
angle than thé slates
themselves. ‘The greatest thickness of the
mass of ore is over 150
feet; and its length is
about 1900; but the dimensions decrease in depth, and at 800 feet its thickness is
about 20, and its length 750 feet; so that there can be little
doubt that the mass will terminate entirely at a certain not
very great depth. The ores of this singular mass are chiedly
sulphurets of iron, zinc, lead and copper, intimately blended
together, and-almost entirely destitute of cangue.
‘The auriferous quartz veins of most gold regions belong
to this class of deposits. They consist of belts of quartzose
matter with sulphuret of iron, which near the surface is decomposed into a hydrated oxide, and contain gold disseminated through these substances, and sometimes in the adjoining rock, in fine particles, or, occasionally, large lumps.
These belts ran with the strata and dip with them, and in
other respects exhibit the phenomena of segregated rather
than of fissure veins. .
Practically, the most important feature of this class of deposits is that they cannot be depended on in depth as true
veins ; as they seem almost always to be richest near the
surface, and frequently terminate altogether at no very considerable depth. Nor is the ore or metal matter distributed

through them with as much regularity as in the true veins, . .
forming often a series of nests and pockets ranged in a general linear direction, and counected by mere threads of ore

Krvrr’s Cast Steen *Tyres.—Two of these tyres have
been loaned to Mr. Krupp by the North London Railway
Company, and are placed in the Exhibition, with his magnificent show of 100 tons of cast-steel cannon, axles, tyres,
crank, intermediate and other shafts, together of the value of
$90,000.
‘The tyres above referred to have run sixty-seven thousand
miles, and do not yet require turning. 'The road is very severe upon tyres, and the engines are of the heayiest class,
and continually under the brake, tho stoppages avcragiug
about every mile.
Here is an extract from a report made to the Board of Directors by their engineer, dated April 14, 1862: “The engines of this line run one million miles per annum, in round
numbers, and this mileage performed by Krupp’s tyres would
cost £733 6s. 8. while by the Low Moor tyres the cost would
be £2,087 10s.”
The average thickness of the tyres is 2.21 inches, and
Krupp’s are caleulated to be worn down to one inch before
they are discarded. To rn 189,539 miles will require one
set of Krupp's tyres, four times turned, at a cost of £139, or
six sets of Low Moor, twelve times turned, at a cost of £396,
without making any allowance for the value of the old me:
tal—which is greatly in favor of Krupp’s. The cost, therefore of running one thousand miles is 14s. 8d. by Krupp’s,
and £2 Is. 9d. by Low Moor tyres, showing a saving of 65
per cent.
It is a remarkable fact that the Belgian steel is even inferior to iron, showing clearly that the quality of Krupp’s
steel, and not the mere fact of his tyres being steel at all; is
the important consideration. —American Railutiy Review.
GiRDS BUDDING KNIFE.
Theaccompanying illustration, executed at this office,
represents Mr. E. D. Girp’s Buppinc Kytes, a most inyaluable invention for the Pacific States. Mr. J. Silversmith, of
San Francisco, has been authorized to dispose of the right
for States, Territories and counties for the Pacific Coast
only.
This invention-is one of the many California has thus far
produced, and is certainly deserving of her, it being the most
useful and practicable for the purposes designed. The horticulturist who once adopts this knife will find its value
so evident that ever after its services will be indispensable,
since with it much labor and expense are saved. In speaking of it the Stientific_Americon says :
“The above engraving illustrates a knife which is caleulated to facilitate materially the process of budding. Upon
the ends of the blades are formed crescent-shaped ctosses of
steel with fine edges for cutting the T-shaped slit in the bark
of the tree to be budded. ‘These blades with their crosses
are made of different sizes, so that some one of the three
may be adapted to the size of the tree to be operated upon.
“Tt is the practice of some horticulturists to remove the
bit of wood which is cut from the scion with the bud, and to
insert the bark only with the bud. To save this operation,
the round blade is formed with several curves in its edge, so
that it will cut the bark alone from the scion without taking
off the bit of wood,'the curves heihg of different radii to
adapt them to scions of different sizes. ,
“ With this knife several operations are reduced to one,
and the process of budding is greatly facilitated. The crescent-shaped cross is pressed through the bark. making the
transyerse cut, and then by simply carrying the knife down,
the vertical slit is made, and the bark is raised at the same
time ready to receive the bud. ‘This knife was used in Galifornia during the last season, for budding several thousand
trees, and it gave great satisfaction to the operators.”
Those desiring to purchase will please address Julius Silversmith, San Francisco, respecting terms, &c.
