SCIENCE AND INDUSTRY .

An improved method or manutac-
turing scissors, or shears. consists in
casting t.c handles of iron. and zen
derinS them malleable. preparing the
steel blades in the usual manner,
welding the blades TO the malleable
handles by hammers or dies acting
up on the parts that are welded
together; finally, suhjecting each
handle and blade. when cold, to a
powerful pressure between dies. The
latter act upon the malleable portion
IN such way as to consolidate the
metal, smooth the surface, and re
move any imperfections there may be
III the shape.
An English mechanic has contrived
a simple and efficient means of sig
mailing between the signal man and
the engine driver, by the Use of a
bell or gong. The arrangement is
lnten led for use with or without ali
air whistle, conformity with the appli-
cation of the brake when air brakes
are used, whether pressure or vacuum
or when electric brakes are ap
piled. BY this form of contrivance,
the use of fog signals in foggy
weather may be rendered unnecessary
the cost Of them. as also the OK
pense of plate layers wages in laying
them, with all the attendant incon
yenlence, may be saved and the use
of the distance signal and cost of
maintenance may also, in many cases,
be dispensed with.
vi. Dessa II, the French chemist, is
still pursuing his interesting invcs-
LEGATIONS i'll respect to the action of
light, already rewarded with the dis
covery that oxygen may he converted
into ozone by the action Of light
rays. In arriving at this result, Nj.
Dessan employed very pure oxygen;
it was contained in a glass globe,
which, together with other appa
ratus, was carefully covered with
black paper, to prevent the admission
Of light. Under these circumstances,
it appears, the oxygen did not betray
the presence of ozone, but after the
rays from Drummond oxyhydrogen
lamp had shone upon the oxygen for
some twenty five minutes, ozone was
distinctly shown to be present on
testing with iodide of starch.
The operation of cruising and sep
arating clay is, it is now claimed.
greatly facilitated by the employment
of an ingeniously constructed ma
chine, recently introduced. This ap-
paratus presents the peculiarity Of
having two rolls set side by side and
parallel with each other. in suitable
housings, each roll having formed on
its face a right-hand groove, thlead
or screw. extending from the centre
to one end-a'so left hand screw or
groove extending from the centre to
the other end The rolls are then set
in their housings, with the right hand
thread or screw on one roll, in oppo
sition to the left hand groove or screw
on the other roll; thus, when the clay
is introduced between the rolls
through hopper fixed centrally
over them, the stones i'll the clay are
carried in the screws or groves to one
end of the rolls and there elected.
while the clay also passes through be
tween the faces of the rolls. and is in
this manner crushed or pulverized to
the desired condition.
A deacon, not accustomed to set
tunes, undertook it in the absence of
the chorister. He pitched it too
high and sang, II love to steal" and
broke down before he could add "a
while away" He tried again. Il
love 10 steal" but broke down again
Once more he rallied and sang: Il
love to steal" but this time it was
too low. and he broke down as usual.
and the pastor arose and said: 1T is
greatly to. be regretted! Let lis pray"
