The number of known explosives is
stated to have increased from twenty
five to LOO in thirty-two years.
Cold is not fatal to mlcro-organisms.
Or. Macfayden and Mr.. Rowland find
that an exposure for ten hours to a
temperature Of $50 degrees c. has no
appreciable effect on the vitality of NIL
cro-organisms.
Prof. Fleming Of London University
is now conducting important expert
ments in connection with the transmits
sion of electrical energy. 1t is said that
the professor has discovered ear by
which power can be distributed with
out wires by utilizing ether.
Caterpillars occasionally crawl from
their hiding places on warm days in
winter. The most common of these is
a thick furred worm with a red coat
banded with black, which has the ap-
pearance of chenille. OF the caterpil-
lars that live through the winter a large
number belong to species that require
more than N season to develop from
the egg to the perfect insect.
Moscow is probably the w~Orst-paved
city in the world. Great cobblestones
driven by hand into a loose bed Of sand
form a roadway which is always dusty
in summer and muddy in autumn and
in many Of the roads there is no at
tempt at a roadway of any kind. The
streets are badly watered and cleaned.
The yearly expenditure for these two
operations is only about $155,OOO.
Every traveller in France has been
struck by the sight of multitudes of
slender poplar trees growing by the
roadsides and brOOksides. Two or three
times in twenty years the branches of
these poplars are trimmed, and the
light wood thus obtained is dried and
sold to bakers, whose practical science
has taught them that the quick, intense
heat produced by burning poplar is ex-
cellent for giving a thick III to their
bread.
A gutla-percha substitute has recent
" been patented. 1t consists of a mix
ture of pulverized peat and resin oil.
The peat is dried thoroughly and is
then pulverlzed and sifted until it is
about the fineness of flour. 1t is then
mixed with equal parts by weight of
resin oil and , per cent Of amyl acetate.
1t is then stirred and worked until it
forms a smooth, dough-like mixture. 1t
can be worked into shape and is semi
hard like gu~tta-percha.
In Central Africa are fou-d districts
which impress the beholder with the
belief that the hand of man has shaped
their features, although there is now
no population capable Of producing
such effects. These districts, near Lake
Tanganyika, are called park lands, u
and their origin was recently explained
before the Linnean Society in London
by Mr.. Moore, as being due to the
spread of vegetation over a light sur
face soil gradually deposited above the
salt steppes left by former lakes. II
some places these districts are covered
with natural plantations that have &
quite hOmelike look"
The balloon races and contests con
Quoted in connection with the Paris
Exposition were productive of some
very interesting results. Every sun
day the spectacle was witnessed of
large number of balloons starting OIL
their journey. zone afternoon" say

point that be had fixed beforehand.
BY taking advantage of the variou
air-currents and s|killfully manipulating
the guideropes, surprising results wer

three of them landed in Russia. Abou
1.4OO miles were travelled in 81 hours.
