SCIENCE AND INDUSTRY.

The Scientific American thinks that
the devices for sending torpedoes to de-
stroy any vessel three miles from shore
in safety, through any kind of sea, may
also be used in sending hfeboats an
equal distance to rescue passengers from
a wreck.
Two marked improvements have
recently been made in the use of gas for
lighthouse illumination. One is process
of enriching gas made from ordinary
coking coal by the addition of hydro
carbon and heated air. The other is the
new dioptric lens.
Mr.. Sinclair has discovered new
mode of respiration in myriapods, the
breathing organ in scutigera holding
q position intermediate between the
trachee of myriapods and the lungs OF
spiders. He holds that the trache@
have developed into the lungs of spiders
and scorpions.
1t is stated that German firm has
perfected means of making profita-
BILE disposition of sawdust by which 1T
is applied to a mechanical use and has
thus far been attended with success.
An acid is mixed with the sawdust and
the whole mass nodded into blocks or
any other form, resulting in a fine ma
terial for building purposes. The blocks
assume extreme hardness of surface and
are practically non-combustible.
-Double-headed snakes have been
known to occur; and in German jour
nal DIR. Collins, of Berlin, describes and
10; ~ Ix md
mentions four other cases of such mall
| formations. Double-tailed lizards have
| occurred. also double-headed and dou-
| ble-tailed fishes. DIR. Collins infers that
all such cases as double tails are due to
abnormal processes of regeneration,
| after the original tail has been lost.
| 1t has been finally settled that the
shoe and leather industry will have a
separate building at the worlds fair.
Representatives of that industry have
! accepted the site offered them, and will
erect, at an expense of 800, 900, a build
ing, measuring $50 by 600 feet, in which
they will show an almost endless array
| of leather products and every process
in their manufacture from the raw hide
to the most finished article.
q The Schweizerische Bauzeitung pub
fishes very interesting note concern
ing the influence of steam on magnets
When heated by steam they lose from
2S to 81 per cent. of their magnetic
| power. But if, after being remagne
tized, they are again submitted to the
action of heat, the loss of power is insig
nificant, and diminishes as often as th'
operation is repeated. This would seen
/ to point to the means of permanently
magnetizing pieces of steel.
| Honey could be immensely i'm
proved by the planting of the flower
known to yield a fine favored nectar
Everyone knows the difference in th'
quality of the comb contents in differ
ent parts of the same country and ii
different regions The Narbonne hone
obtains it's fine favor by being harveste
chiefly from labiate plants, such as rose
mary, ETC., and though it appears tina
the Maltese honey does not, as ofte
stated, owe its fine aroma to orang
blossoms, the latter undeniably pei
fumes the Greek honey.
} The census bulletin shows the tots
area of land devoted to the cultivatio
of hemp in the United States in 1889, t
| have been 25, O54 acres, and the produC
; ton of fiber 1,511 tons, valued g
|, 81, ,1O2, ,6O2. The average yield per acr
is 1,029 pounds, and the average valu
per acre s44.Ol or s95. 70 per ton. KeI
| lucky produced 93.s7 of the total hem
| crop of the country. Illinois produce
4.S3 per cent. and the remaining 81
states from which hemp was reporte
had an aggregate yield of only 161 ton
Following are Some interesting st
d tistics of the rapidly developing industr
Of Argentina. The area of the cane plal
e tations this year is AZ, 500 acres, which,'
L the usual rate of production, will vie
!, 1,s79, ,Oo0, 900 pounds of cane. The arr
d of cultivation in 1889 was 34,250 acr
and the yield was 100000 pounds
S cane. The gross value of the crop tn
n year is estimated at $12, 75O, 600, as cor
e pared with s6, 1876, 600 in 1889. There q
e thirty-six sugar factories, representa-
n a capital value of about s20,0Oo,000
g gold. The actual production in Is
n was 77,O0O. 900 pounds, and this yea,
weld is estimated at $4,000, 900 pound
or 81, 500 ogsheads.-Chicago Herald.
