SCIENCE AND INDUSTRY,

:, About $40. 900, 900 is paid every year
IN Germany for the creation and pres
ervation of forests; 200, 900 families are
supported for them, while something
like 3,000,000 find employment in the
various wood industries of the empire
The total revenue from the forests
amount to s14, 500,0 900 and the current
expenses are So, 500,O 900.
Water always crystalizes in the
hexagona1 or six-sided system, and con-
sequently all snow crystals must be
formed by the combination of hexag-
onal, or in occasional cases. triangular
(hemihedral) forms The variety of
snow crystals is innumerable, but they
will always be found to have six sides
and angles, or multiples of that num-

New Zealand cheese and butter.
makers have urged their government
to secure the services of leading ex-
pert, to lecture and instruct In cheese
and butter making. They also advise
the establishment of a model factory,
the granting of certificates for skill,
also that the produce shipped to the
London market should be inspected by
a competent judge before being offered
for sale.
Assuming that each sheep clips four
pounds of wool, the English farmer is
receiving Is cents per sheep less, an
nual1y, than his average between 1860
and 1880. This makes a difference of
S75 on every hundred sheep, and as the
sale of wool Is estimated to make one
third of the gross revenue to the sheep
farmer, this is very serious factor in
his income.
DIR. Sanermann publishes in the Ga
zette de FRANKFORT some interesting re-
marks about artificial coloration OF
birds. Canaries, he says, when fed with
cayenne pepper, gradually change their
color. passing from yellow to red. Cay
enne pepper contains tinetorial sub
stance. an irritative principle and an
oil. When the last two substances are
extracted by sleeping in alcohol, pepper
loses its coloring properties, but an ad-
dition of olive oil restores them. From
this fact the conclusion is drawn that

"A remarkable discovery in the do
main of medical science is reported from
Vienna. DIR. X. L. Schleich claims that
the results obtained by the use of chlo-
reform and cocaine may be secured by
simultaneous Injections of solution of
sugar or salt or even of simple cold dis
titled water, while the i'll effects that
sometimes follow applications of the
former are avoided. This claim, it is
asserted, is based upon a series of ex-
periments, and some medical authori-
ties are said to be satisfied of the genu-
ineness of the claim.
Lizard skin has for the past two
seasons or so been a very popular mate
rial for card cases, purses, pocket-boobs,
and such articles, and large business
has sprung up in meeting the demand
for the raw material Over 500, 600
lizard skins were imported from the
Mexican state of Tabasco alone last
year, and the local governments esti-
mate puts the number of lizards killed
in that state during the same year. at
full j, 00O,0 900. Many of the skins went
to Europe, and large Quantities are
marketed in Mexico.
The delicate threads for hanging
the galvanometer needles are usually
made of silk! but Whistler finds that
fiber drawn from quartz cum be OBJ
tanned much finer, and IS 5:4 times
stronger than silk fiber of the same
diameter, and 4 times stronger than a
steel wire. The quartz fiber showed
also AZ times more scnsitiveness than
the silk fiber, and the needle returned
exactly to the zero point, which was
not the case with silk. The quartz
fiber, therefore, appears to be better
adapted to this Use than silk.
During 1892, I'll vessels aggregating
1, ,261, 107 tons were launched in the
United Kingdom. OF this number thir-
ty were war ships, aggregating Isl, 157
tons displacement The remaining 681
vessels totalled /, 100, $50 tons The out
put of the year falls below that of 1891
by about q, 900 tons. In both years the
| proportion of sailing tonnage was un-
usually high, amounting last year to
| over "a per cent, and in 1891 over %
per cent of the total production. The
output of 1880 Is the largest on record.
Making allowances for estimated pro-
| portionate values of steam tonnage
compared with sailing tonnage, the
output of 1899 was $50 600 tons below
| that of 1889.
