The difficulty of welding the new
tool steels to cheaper grades has led to
the invention Of new process. by
which the Yields are successfully ac-
complished. 1t consists in placing
thin sheet of copper between the sur
faces to be welded, which are coated
with reducing substance. At a tenn
perature of 200 centigrade the copper
is rendered completely fluid by the gas
or yapor given OF by the reducing sub
stance, and In this state 1t penetrates
Into the steel on both sides Of the
junction, producing cohesion OF the
molecules SO strong that II the welded
piece Is afterward broken, the fracture
tends to pass through the steel on one
side or the other, instead Of following
the weld.
The recognition of the important
part played by certain insects In the
spread of disease has led to the organ
tzation of the African chronological
Research Committee. Two trained en-
tomologists are to be dispatched to
Africa, one on the east and the other
on the west coast, to study the noxlous
insects, interest residents in the prob
lens which they present, and promote
scientific knowledge of the best ways
Of iexterminating them The Natural
History Department of the British Mu-
scum, the London and Liverpool
Schools Of Tropical Medicine and the
leading English universities have Of
fered to take part in the work. The
committee will cooperate with work
done by other organizations in Egypt,
the Sudan and South Africa.
Near OAK, In southwestern France.
exists very remarkable oak, which is
an object of generation for the inhab.
itants of the surrounding regions. Its
short trunk is encircled with gigantic
raised roots, giving 1t, at the level of
the ground, circumference Of SO feet.
The massive branches spread over a
circle SO broad that 500 persons can.
find room beneath them. The age of
the tree is estimated to be not less
than 1000 years, yet 1t shows few
signs of decrepitude, although the sin
terror of the trunk is hollow. It is
the first tree In the neighborhood to
cover itself with leaves, and the last
to be deprived of them. At the juno
ton of the immense branches are two
cavities, which are always full Of
water, and the peasants ascribe mir
aculous properties to this water. Once
every year there Is pilgrimage to the
sacred oak of Quillacq and at mid
night between June % and "a the pill
grims begin their deyotions around
the foot of the tree.
Speculation as to the origin/of the
| meteoric stones and irons that occa-
sionaly fall from the sky has pecu-
| liar charm for the Imagination The
density of these bodies and the great
size of some of them constitute argu-
ments in favor of the view that, they
must have been elected from some
massive body in space. such as the sun
| or a star. In discussing the peculiar
mteorites which fell some years ago at
Il bTSuudlup III. ". w.
suggests that we may infer, from their
composition, from what part OF the
heavenly body that elected them,
they came. The heavy metallic
meteorites. called siderites, may
plausibly be supposed to have
come from the deeper parts OF q
star; the light. stony ones. called aer-
olites, from the superficial layers; and
the rare "pallasites," like the Bren-
ham meteorites, which are interme-
diate in composition. from the transit
tional zone between the outer crust
and the dense interior nucleus.
Every man thinks that as he is pass
ing through the world. he does .
whole lot of good he gets no credit
for.
