Ero,, the renort of i smallpox hos

From the report of a smallpox hos
pital near London it appears that an
nnyaccinated child runs q risk OF
death from smallpox more than sis
times us greatas the child who has
undergone the harmless operation nee
essary to protect him from that disease
The forest land in European Russia
is rapidly decreasing, threatening u
loss of wood supply and serious
change of climate. Its area is now es-
timated at 33 per cent of the total area
of the country, while that OF Austria
is 30 per cent, of Germany rs, France
10, Italy Is, and Turkey IA per cent.
Prof. G. f. Wright infers that the
Niagara River has worn the whole OF
the gorge from Queenstown to the
falls, with perhaps some little help
from re-glacial erosion above the
Whirlpool. The rate of erosion, calcu-
lated at about three feet year, would
make the time required not over TO-
600 or $4,000 years,
An English observer has declared
that fully one bushel of grain per acre
has been destroyed hy small birds
alone in his country. He has estl-
mated that if the number OF small
birds were reduced by one-half the
annual saving to the country would
amount to more than $3,600,000.
A quarter of II century ago a!r. u. T..
Symons instituted the first general
series of rainfall observations ever
made in England. He has since then
gradually extended his system, ana
there are now nearly 5000 observers,
no less than 2433 stations having fur
ished perfect records of the rainfall
last year. Valuable in many ways as
this work may be to the English
people, the observers have not only
rendered their services without COM
pensation But have also borne most OF
the expense of making known the re-
suits of their observations. II
OF all solar problems" said Prof. c..
a. Young in. his annual address as
president of the American Associa-
ton for the advancement OF Science,
"the one which eXcites the deepest
and most general interest is that re-
lating to the solar heat its mainten-
ance and it's duration. For my own
part. find no fault with with the
solution proposed by Helmholtz, who
accounts for it mainly for the slow con-
traction of the solar sphere. The on
ly objection of much force is that it
apparently limits the past duration OF
the solar system to a period not much
exceeding some twenty millions OF
years; and many of our geological
friends protest against so scanty an
allowance. The same theory would
give us perhaps, half as much time
for our remaining lifetime, but this is
no objection, since | perceive no reason
to doubt the final cessation of the
SUMS activity, and the consequent
death of the system.
Researches by Swedish and Finnish
sayants furnish evidence that salmon
are in the habit of making enormous
journeys across the Baltic-quitting the
rivers of the northern Sweden and Fin
land in the autumn for visit to the
shores of Northern Germany during
the winter, and returning to theif
haunts in the spring. In Germany
land Norway efforts have been made
to learn something of the migration of
salmon through the plan of liberating
carefully marked specimens and offer
ing rewards for particulars concerning
their re-capture. In 1872 a thousand
marked salmon were turned into the
Weser, but not until u few weeks ago
was the first capture of a marked fish
reported the fish being taken near the
place where it was put into the river
its weight being thirty pounds, and its
marks showing that it was thirteen
years old in 1882. Several hundred
salmon and trout, plainly marked
with tags, were liberated in Norway
during last autumn and winter;
