One thing especially noticed in Maine
is the impetus given to the apple can
ming business by the partial failure of
the apple crop. Fruit that was formerly
considered only good enough for cider
escaped the press this year and has gono
into cans to help to furnish the world
with apple sauce.
"A year ago the average daily pro-
duction of petroleum in Pennsylvania,
according to tho PHILADELPHIA Times,
was SO, 900 barrels. Now it is 5000.
The prime cause of this increase was
the advance to a dollar per barrel in
price whom the production fell to so, 600
barrels, and the effect of the increase to
$1,000 is u drop in prices to 20 cents
"A remarkable fact has been con-
clusiyely demonstrated in regard to beet
culture in Germany, that the longer the
variety of beet root the smaller the per-
centage of sugar have tho smaller roots.
A poor crop, as it might be called, pro-
vided it is of variety naturally with
small roots, does not indicate u poor
crop of sugar.
"A London merchant reioices be-
cause he tried music as a medicine. His
boy, six years old, was dying with ty-
phoid, and was quite insensible with no
appearance of being able to live through
the night Knowing his sons fondnesS
for music, the father procured large
music box, and caused it to play, with
the result that the child's attention was
aroused and his life saved by the reac-
ton
The most complex of all tho animal
tissues is the brain. The fibers in one
single optic nerve have been counted
under microscope TO the number Of
about 500, 900. When you consider that
the brain is largely made up of fibers
you see how vast this number becomes.
SO with regard to cells: they are count
less. No method of science has been
able to count the cells in single square
quarter of an inca of the outside cover
ing of the brain.
The Ministry Of Imperial Property
has decided to take energetic measures
to develop the resources of the districts

There is enormous mineral wealth in
those districts, and the woods and the
lands that can be made arabic would
yield large returns to the government
if properly managed. The forests Of
those two districts occupy no less shan
go, 900 dessyatins, about 200, 200 acres Of
land.
1t seems probable that the great, at
least the immediate, flu ture of astronomy
lies in the judicious use of spectroscopy
and photography, rather than in the in
crease of optical power by the construc-
ton of large telescopes. Give a small
telescope with a plate attached to il
time enough and it will see as muci2
as big one will show to the most
sensitive eye. AS dry plates will retain
their sensitivenesS, exposure can be
continued for days, shutting off the
light when the object has sunk too low
in the west, and recommending it when
ltshall be high enough in the east again

"A correspondent of the London
Times says that on September 30 he and
his party saw rainbow which formed a

an hour during their ascent of the Fin
steraarhorn. There WERE" he says,
heavy clouds lying some 1000 feet be-
low, on the Aar glacier, and it was on
these that the beautiful, brilliantly coll
ored ring lay. A secondary circle was
also visible. We were near the summit
of the peak when we first observed it,
and from that point the face of the
mountain on the Grimsel side is almost
perpendicular.
Even now we have some active vol
canoes of no little energy on our earth,
and we know that in former days the
volcanoes must have been still more
| powerful; that, in fact the Vesuvius of
the present must be merely pop gun
in comparison with volcanoes which
have shaken the earth in those primi-
tive days when it had just cooled down
from its originally fiery condition. 1t
seems not impossible that some of those
early volcanoes may in the throes of
their mighty eruptions have driven up
pieces of iron and volcanic substances
with violence great enough to shoot
them off into space.
