Inc Qlmculty or 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 a
thin sheet Of copper between the sur
faces to be welded, which are coated
with reducing substance. At tenn
perature of 1900 centigrade the copper
is rendered completely fluid by the gas
or vapor given off by the reducing sub
stance, and in this state 1t penetrates
into the steel on both sides of the
junction, producing a cohesion of the
molecules so strong that If 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.

Africa, one on the east and the other
on the west coast, to study the noxious
insects, interest residents in the prob
lens which they present, and promote
scientific knowledge of the best ways
of exterminating them. The Natural
History Department of the British Mu.

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

Near Dax, In southwestern France
exists very remarkable oak. which 1!
an object of veneration for the inhab
itants of the surrounding regions. 1T
short trunk is encircled with gtganti
raised roots, giving It, at the level o
the ground, circumference Of 50 feet
The massive branches spread over
circle so broad that 500 persons cal
find room beneath them. The age o
the tree is estimated to be not les
than 1000 years, yet 1t shows fey
signs of decrepitude, although the In
terror of the trunk Is hollow. 1t 1
the first tree In the neighborhood t
cover itself with leaves, and the las
to be deprived Of them. At the june
tion of the immense branches are tw
cavities, which are always full Q
water, and the peasants ascribe mil
aculous properties to this water. Ono
every year there is a pilgrimage to tn
sacred oak of Quillacq, and at mit
night between June % and "a the pi
grims begin their devotions aroun
the foot of the tree.
Speculation as to the origin of tn
meteoric stones and irons that occ;
sionaly fall from the sky has pee,
liar charm for the imagination. Th
density Of these bodies and the gres
size of some Of them constitute arg
ments in favor Of the view that the
must have been elected from som
|, massive body in space, such as the su
or a star. In discussing the peculis
, mteorites which fell some years ago
, Brennan, Kan, DR.. o. w. Huntingto
suggests that we may infer, from the
composition, from what part Of tt
heavenly body that elected ther
: they came. The heavy metall
, meteorites, called siderites, ma
, plausibly be supposed to ha,
come from the deeper parts of
star; the light, stony ones, called ae
, olites, from the superficial layers; ar
' the rare ''pallasites," like the Bre
ham meteorites, which are Intern
, diate in composition, from the trans
\ tional zone between the outer cru
and the dense interior nucleus.
