Louisiana is becoming very i'm
portant sugar and lumber State.
The boy bakers in San Francisco's
| industrial school make bread for all the
public institutions.
"A meteorological station is to be es-
tablished at Tiberias, Palestine, which
| is $50 feet below the level of the Medit-
erranean.
M. Beauregard, an eminent Egypt
ologist believes that Egypt at che time
of the Pharaohs exhibited the mixed con-
dition of combining the use of flint i'm
plements with acquaintance with the
means of extracting copper and blend
ing 1t with other metal.
| "A now textile material, called vege-
table flannel, is now being manufactured
| in Germany, out of pine leaves. The
fiber, somewhat resembling hemp, is
spun, knitted and woven into under.
garments, blankets and clothing OF
various kinds. This fabri3 is said to
keep the body warm without heating,
and is exceedingly cheap and durable.
I'm observations with kites and bal.
looms, Prof. Leonhard Weber has found
that the atmosphere is negatively elec-
trified up to height of about one hum
dred yards, beyond which tits positively
electrified in degree increasing very
rapidly with the distance from the earth.
The negative electrification of the lower
| strata of the air is attributed to the
presence of germs and dust particles.
The authorities say that the dura-
tion of a lightning flash is not otinfinitesi-
NAL, but that the flash lasts a measura-
BILE time. For example, if one sets a
camera in rapid vibration and exposes
in it plate so as to receive the impress
sion of the flash, it is found that the i'm
pressions appear widened out on the
negative, showing the negative to have
moved during the time the flash was in
| existence.
-"I notice." said prominent brick
maker to a Detroit Free Press reporter,
that there is now being introduced into
this country the famous Swiss patent for
making iron-clad brick" ''Iron-clad
brick?" "Yes, sir. That is to say, the
clay is mixed with certain amount of
iron ore and burned under certain re.
quirements of temperature, in a pecu.
liarly made kiln, etc. The result ia
something startling. Such brick are un.
surpassed even by stone itself. For paw.
ing they are simply unapproachable.
hope to see our Detroit manufacturers
take hold of this thing"
One of the industries now followed
in London, and certainly a novel and re-
markable one, even for this age, is that
of separating and storing. oxygen from
the atmosphere. This interesting pro-
cess has unique application in the ma
turing of spirits and in improving the
quality of beer, and, though this is far
from being the only application which
is made of pure oxygen, it is one which,
for various reasons, has excited most at
tention, especially in that department
of trade, on account of it's financial bear
ings. 1t is claimed that the oxygen, in
its contact with spirits, actually accom-
plishes in few days what, if left to the
natural and usual process, requires a
period of from three to five years. The
oxygen, it is said, gets rid of the fusel
oil quickly, thus relieving the liquid of
its most injurious property, and not only
this, but a maturer effect is also pro-
duced on beer by admixture with oxy-
Uen.
