SCIENCE AND INDUSTRY

Evansville, Ind, miners viii run a
cooperative mine.
Within a radius of forty miles Of
Rochester, N. Y, there are more than
1,50O fruit evaporators, with capacity
varying from twenty-five bushels per
day to 1000 bushels each.
Fifteen years ago there were no
oranges shipped from California, while
last year over three thousand carloads
were exported. In 1875 the Southern
Pacific road shipped 500 pounds of rails
ins; last year 26, 900, 900. In seventeen
years there has arisen an industry
which in 1890 returned to California
people Ss,OO0,OOO.
The transit of Mercury was success
fully observed at the Naval observatory,
Washington. The best observations
were made with two telescopes of three
inches aperture. The astronomers of
the Naval observatory are well aware
of the fact that small telescopes are
best for viewing objects near the hori-
Eon, while large ones are practically
useless.
DIR. Holbrook attributes the preva-
lent poor quality of our teeth largely to
their lack of employment, owing to our
use of foods cooked soft, and so he
recommends the eating of raw, dry,
hard wheat, which duly exercises the
teeth and promotes flow of saliva-say,
teaspoonful daily. Nails, hair and
teeth-analegou tissues that thrive in
savagedom-seem to be ''fading, still
fading" with the progress of civilization.
--"Silver Thaw' is the name applied
to a winter phenomenon of frequent
occurrence at Ben Nevis observatory.
It consists of rain falling when the air
is below freezing point and congealing
whenever it reaches the ground. Of
course, this points to an inversion of
the temperature, which is lower on the
mountain-top than at greater heights,
and, being largely associated with a
| cyclonic distribution of pressure, it is
of considerable ''forecasting" value.
Monsieur Monnet uses chloride of
ethyl as local an@sthetic instead of
the ether spray, and DR.. Redard, of the
Geneva School of Dentistry, thinks it
very useful, as it should be for several
purposes as it can be employed without
apparatus. 1t is put up in Theoretically
sealed glass tubes, which at one end are
| drawn out into a fine point. On break
ing off the end of this capillary tube,
the warmth of the hand holding the
other end is sufficient to cause the
chloride to be expelled in a fine jet,
which, vaporizing directly, freezes the
substance on which it is directed.
AT a recent meeting of the Royal
Society, of Edinburgh, DR.. A. Bruce
read paper on case of cyclopia, or
single eye, which has come under his
notice. There was single socket for
the eye, of lozenge shape, and situ-
ated in the middle of the base of the
forehead. The socket was furnished
with two pairs of eyelids, upper and
lower. The nose was represented by q
short process of tissue and skin attached
to the forehead above the medal eye.
A microscopic section of the socket
showed two rudimentary eyes, with the
two rudimentary retinB apparently
springing from a single optic vesicle.
Nobody thinks of New Jersey as a
possible rival of California in the MAX
ing of wine or as competitor with
France in the growing of grapes, yet
time may prove it such. The first grape
growing in New Jersey was done in the
sandy region around Bridgeton and
Vineland, but the industry has since
followed the piney sand belt almost to
South Amboy, and grapes are now con-
sidered in the categories of half the far
mers of Ocean and Monmouth counties.
There have been bad years recently,
when there was production, but
nothing has hindered the growth of the
business, and this year more acreage
than ever is devoted to grapes. There is
as yet no wine making to speak of, but
the outlook is that we shall presently
all be drinking New Jersey claret and
wondering whether it comes from
France or California.
