"A large vein OF pure white sand,
suitable for making glass, has been
found near Pittsburgh, Pa. The dis.
coyery will save the glass manufact-
urers of that city thousands of dollars
annually, as they have hitherto been
obliged to send across the Allegheny
Mountains for their sand.
An engineer of Manchester, En-
gland, is introducing novelty in paper,
viz, paper fle-hafts and tool-handles,
which are said to be practically indie.
structible and much cheaper than wood
or malleable iron hafts. Placed under
steam-hammer, although they can be
flattened, they can not be split or
cracked. ss.
"A sample of oranges pluclsed from

Victor Meyer, an eminent German
chemist believes 1--WE may reasonably

.ered like starch, in boiling water, yet
both the wood fiber and the starch can

Aluminium and alloys aie now pro-
uced in considerable quantities by
hree distinct methods from certain |
lays, corundum, etc. In one case the |
aetallic sodium retorting process is en-
mployed, in another the electrical |
melting furnace process, and in a third
he direct smelling substitution process |
J resorted to. The last-named method,
'hich has proved very successful, con-
lists in producing chemical alloy
'ithin water-jacketed furnace and
,etal fume condenser = without any
,etallic sodium or electricity the
roduct being equaled by only one
ther, which may be classed as the
olidified solution of one metal into
mother.
