The ocean contains about 2,139
grains of salt and other solids per gal
Ion. and the Dead Sea about 1900
grains per gallon.
Glass bricks, German product, are
translucent. but not transparent, and
possess the advantages Of being acid
proof and of harboring no disease
germs.
The celluloid wind screens of auto
mobiles give great risk Of fire. Very
fine copper gauze is said to have proven
a satisfactory substitute, being easily
seen through and non-inf1ammable,
while it does not crack like celluloid.
The low efficiency Of the steam en-
CINE tempts inventors with great posi-
bilities Of saving fuel. NJ. Cantor.
European engineer, has hit upon an
altogether new form Of heat engine,
and proposes to use for power the ex-
pansion Of the gas produced by the
burning Of liquid fuel-like petroleum
and alcohol-when sprayed upon a
white hot oxidizing material, like
oxide of copper. The oxygen removed
from the copper Divide would be re-
stored by an air jet. Pending practi-
cal test, 1t is claimed that the highest
possible rate of expansion would be
produced in the working gas, and that
a greatly increased thermoydynamie
efficiency would be secured.
Professor w. e. Ayrton points out
that the common expressions buying
electricity" and consuming electric
current are misleading. No electricl-
ty is used up in lighting buildings,
driving machinery, and propelling cars
and trains. "Just as much electricity
flows away per minute. through the
return conductor, from your electric
ally lighted house as flows to 1t
through the coming conductor. The
electric current is like butchers cart
carrying round meat-you no more
consume current than you consume
cart. 1t is not the vehicle but what 1t
leaves behind that the consumers buy,
meat in the case of the butchers cart,
and energy in the case Of the electric
current"
The construction of an ordinary tele-
graph-line between Lima, on the Pa
cific side Of the Andes in Peru, and
Iquitos, near the Amazon, being all
but impossible, because Of the density
Of the forests and the animosity Of
the ignorant natives, the wireless
method is to be employed. Already
communication by wireless telegraphy
exists between Lima and Puerto Ber-
mudez and this line will be extended
to IQuitos, distance Of about 600
miles, with three intermediate stations
If the enterprise succeeds, it is the in
tention to extend the wireless COM
munication across the whole width Of
Brazil to Manaos and Para, thus link
ing the Atlantic and Pacific oceans
across the Andes and the great Bra
lillian plains.
The Pomelo, sometimes called the
Chinese breadfruit, citrus-fruit
which may be described as cross be-
tween the orange and the grapefruit,
combining the good points Of both, is
the subject Of an interesting report by
Mr.. Anderson, the United States con-
sui at Hangchow. Mr.. Anderson re-
CARDS it as the finest fruit grown in
the far East. He believes that 1t
might be introduced with profit into
the southern United States. Already,
1t is understood, a few persons in this
country are cultivating the pomelo
but not upon a commercial scale. In
China, it is believed, this fruit has
been cultivated for at least 1000 years
The best pomelos in the world are said
to come from a little valley near q
large Chinese city named Chang Chew,
lying inland from Annoy, and not yet
opened to foreign trade. The sum-
mers in this valley are hot and rather
damp, and the winters are without Sc
| we're frosts.
