Recent experiments have demon
strated that an incandeseent electric
light of 100-candle powder. sunk twenty
feet in the ocean. will illuminate the
surface sufficiently to distinguish OBJ
jects within radius of 25O feet.
Experiments ON the speed of the
electric current prove that if proper
conductor could be wound around the
globe : ,nal parting from it at any
point of it would return to the starting
point in one-half of second.

Pulled woods are largely used in the
manufacture of tiaunels. and one reason
Of their being SO used is because the
process of pulling, either by burning or
sweating. destroys the telling properties
Of the fiber, and so better fits it for use

Cream of tartar occurs in the Juices
Of many fruit, among them the grape
and pineapple; and W hen the grape
juice is being fermented to make wine,
a hard crust. known as argo. is formed
On the sides of the cask, consisting main
ly of acid tartrate of potassium. but also
containing tartrate of lime and some
,oloring matter of the wine.
The force popularity believed to be
exerted by nitro-glycerine and dyna-
mite, when exploded. is somewhat
mis-estimated. Thus experiments show
that the power developed by the ex-
plosion of a ton of dynamite is equal
to 1915 foot-tOns: one ton of nitro
glycerine, similarly exploded. will exert
a power of ca, 452 foot-tons, and one
ton of blasting gelatine, similarly ex-
ploded, shows force of 1850 tons.
More than S1O.OOO.OOO worth Of
oysters were shipped from Maryland to
all parts of the world this season.
Over fifty thousand persons are en-
ployed in the industry in the State, and
it supports besides l 800 schOoners and
sloops. To enforce the law for the reg

tains an ''oyster navy" consisting Of
five steamers, six schooners, and eight
sloops.
1t has long bee known that gold
is to some extent volatile at high tenn
perature; but it is evidently far more
volatile than has hitherto been believed.
Mr.. Crookes mentioned incidentally at
the last meeting of the English Chem
ical Society that he has found gold to
boil violently when heated in the
oxyhycrogen flame, and. in fact, to be
30 volatile that there would seem to be
no doubt that it might be distilled in
an apparatus similar to that employed
by Stas in distilling silver.
"A new theory of the formation of
mountains has been offered by MIR. T.
Melard Reade, the we'll known En-
glish geologist. He supposes that the
periods of great sedimentary deposit
that preceded the birth of every large
mountain range have been followed by
great elevation of temperature, pro-
ducing expansions of the strata, with
consequent forcing up of ridges.
Laboratory experiments with the var
ious rocks show that heating would
give such results.
