stroy any vessel three miles from shore
in safety, through any kind of sea, may
also be used in sending lifeboats an
equal distance to rescue passengers from
wreck.
Two marked improvements hzvo
recently been made in the use of gas for
lighthouse illumination. One is a process
of enriching gas made from ordinary
coliing coal by the addition of hydro
carbon and heated air. The other is the
new dioptric lens.
Mr.. Sinclair has discovered a new
mode of respiration in myriapods, the
breathing organ in scutigera holding
position intermediate between the
tachee of myriapods and the lungs of
spiders, He holds that the trachee
have developed iato the lungs of spiders
and scorpions.
1t is stated that German firm has
perfected a means of making profta-
bic disposition of sawdust by which it
is applied to u 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 fine ma
terial for building purposes. The blocks
assume extreme hardness of surface and
are practically non-combuStible.
--Double-hcaded snakes have been
known to occur; and in German jour
nal DR. Collins, of Berlin, describes and
figures double-tailed earthworm and
mentions four other cases of such NAL
formations. Double-tailed lizards have
occurred. also double-headed and dou-
| N.,t1 1NI E.ls
all such cases as double tails are due tc
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 900 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.
The Schweizerischc Bauzeitung pub
fishes "a 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-
nifcant, and diminishcs as often as the
operation is repeated. This would seem
TO point to the means of permanently
magnetizing pieces of steel.
Honey could be immensely i'm
proved by the planting of the flowers

Everyone knows the difference in the
quality of the comb contents in differ
ent parts of the same country and in
different regions. The Narbonne honey
obtains its fine flavor by being harvested
chiefly from labiate plants, such as rose
mary, etc, and though it appears that
the Maltese honey does not, as often
stated, owe it's fine aroma to orange
blossoms, the latter undeniably per-
fumes the Greek honey.
The census bulletin shows the total
area of land devoted to the cultivation
of hemp in the United States in 1889, to
have been 25,0j4 acres, and the produc-
| ton of fiber 11.511 tons, valued at
81, 102, ,602. The average yield per acre
is I ,020 pounds and the average value
per acre S44.01 or $95.79 per ton. Ken
tuckY produced 90. 81 of the total hemp
crop of the country. Illinois produced
4.S3 per cent. and the remaining six
states from which hemp was reported
had an aggregate yield of only 161 tons.
Following are some interesting sta
tistics of the rapidly developing industry
of Argentina. The area. of the cane plan
tations this year is Al, 500 acres, which. lat
the usual rate of production, will yield
1,S79, ,OOO, 900 pounds of cane. The area
of cultivation in 1889 was 34,25O acres
and the yield was 1,5O7, 900 pounds of
cane The gross value of the crop this
year is estimated at S12, 75O, 900, as COM
pared with Sc, 1G5 900 in 1889. There are
thirty-siX sugar factories, representing
capital value of about S20,0OO,00O in
gold. The actual production in 1899
was 1900, 900 pounds, and this years
yield is estimated at 100000 pounds,
or $4,000 ogsheads,-Chicago Herald.
