INDUSTRIAL.

A NEW industry is the shipment of liv
frogs from this country to England TO
breeding purposes.
The following is given as simple
welding powder: One part dry borax, on,
part fine iron filings, one-quarter par
prussiate of potash; it is sprinkled on til,
surfaces, the latter being previously slight
ly moistened. The pieces of iron ant
steel are then tightly bound together witt
iron wire, heated to about 800 degrees, anG
lastly placed under steam hammer OF
passed through rOlls.-Scienttfc Ar1erican
THE trade In tissue-paper patterns il
enormous. One house recently ordered
5000 reams of paper and 100000 envel
opes in which to place the patterns. These
patterns are SO perfect that dresses for cos
| tune parties are easily mac G, and are fast
becoming popular. These patterns are a
real boon to the mother Of family living
| far from any village or settlement. Every
garment worn by men, women or children
can be made from them; they are notched
at the places to join them; the number of
yards for each garment and its trimming
is faithfully given, ingenuity is fostered,
comfort is promoted, and, in fine, we are
inclined to class paper patterns among the
great inventions of the age.-N. Y. Sun.
AN extensive manufacture of lock and
morticed bricks is carried on at Water
bury, England. These bricks, while pro-
ducing workmanship greatly superior to
walls built with pressed brick-being
tongued, grooved and locked at intervals
at each angfe-are also found to be strong
er than common handmade bricks, be-
sides possessing the additional recon-
mendation of effecting saving of two
thirds in the material used. These lock
and mOrticed brick, it also appears, are
adapted to extensive and varied uses, and
are specially serviceable where space and
light with solidity are an object. Their
usefulness is likewise very manifest it Is
stated, when employed for the building Of
or sustaining and retaining entertainments,
sea and other walls, quays and river front
ages, as also in the erection of shafts, and,
in fact, the formation of all works to
which bricks can be applied.
A VERY important, but, until quite re-.
Gently, neglected, constituent of the waste
heap are the old iron, battered saucepans,
old pals, rusty hoops, and hOrse-shoes and
nails from the road. All waste soldered
articles now have the solder extracted from
them, as it is more valuable than the iron
and the cheaper metal is then melted. Nor
are the hOrseshOe-nai1s mixed with the
common east-iron, as they are much sought
after by gun makers for the purpose of
making stub-twist barrels. Scraps of iron
it is found, may be made very useful in Sc
curing the copper in the strecms washing
veins of copper pyrites; pieces of bat
tered iron are placed in tanks, into which
these are collected, and under these cir
cumstances the copper incrusts the iron, in
process of time entirely dissolving it,
mass of copper thus taking the place of
the iron, and the residuum, in the shape
Of colored deposit, is at times taken out,
dried and smelted. These are but few
among the almost numberless examples of
utilization processes now in vogue, and by
means of which the merest and apparent
ly most worthless waste is made to yield
an important value.
