One thing especially noticed in Maine
~ the impetus given to the apple can
ming business by the partial failure of
sne apple crop. Fruit that was formerly
considered only good enough for cider
escaped the press this year and has gone
INTO cans to help to furnish the world
with apple sauce.
"A year ago the average daily pro-
ouction OF petroleum in Pennsylvania,
according to the Philadelphia Timea
was 60. 600 barrels. Now it is IS. 600
The prime cause Of this increase was
the advance to dollar per barrel in
price when the production fell to 90, 600
barrels. and the effect of the increase to
$4,000 is drop in prices to 70 cents-
"A remarkable fact has been con.
clusiveiy demonstrated in regard to beet
culture in Germany, that the longer the
variety Of beet root the smaller the per
centage Of sugar have the smaller roots
A poor crop, as 1t might be called, pro-
vided 1t Is OF variety naturally with
small roots, does not indicate . poor
crop of sugar.
"A London merchant rejoices be-
cause he tried music as 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-
tion.
The most complex of all the animal
tissues is the brain. The fibers in one
single optic nerve have been counted
under microscope to the number of
about 800, 900. When you consider that
the brain is largely made up of hbers
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 inch of the outside cover
ing of the brain.

to develop the resources of the districts
Of Batum and Karsk on the Black Sea-
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

those two districts occupy no less than
60, 900 dessyatins, about 200, 900 acres Of
land.
1T seems probable that the great at
least the immediate, future of astronomy
lies In the judicious use of spectroscopy
and photography, rather than in the in
crease of optical power by the construc-
tion of large telescopes. Give . small
telescope with plate attached to it
time enough and it will SEQ as much
as big one will show to the most
sensitive eye. As dry plates win retain
their sensitiveness, exposure, can be
continued for days, shutting of the
light when the object has sunk too low
In the west and recommending it when
itshall 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
complete circle. visible for nearly half
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 col
ored ring lay. A secondary circle was
also visible. We were near the summit
of the peak when we first observed 1t,
and from that point the face of the
mountain ON the Grimsel side il 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 a 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 q violence great enough tn shoot
them of into space.
