we're demonstrated at recent trials carried
MI ot Treherbert, Rhondda valley, South
Wales. In the first experiment an eighty

Ia side, was smashed through by an ounce
and half OF carl o-dynamite, about nine
inches of the rail being blown clean away.

we're also exploded inside two thick lead
cylinders of a capacity of four and three
| f1urtb cubic inches, with the result that
mis- capacity was expanded to nearly thirty

dynamite.
Similar charges Of the two explosives
we're then placed inside two thick steel
tubes. each one foot long. The ordinary
dynamite burst its tube well, but the carbO-
dynamite did its work much better, bending
the tube as well as bursting it, and sending
| il some fifteen yards from the point of ex-
p0siOn.
The last experiment in the open consisted
| in placing one ounce each OF carbo-dvna-
mite and ordinary dynamite on fat steel
disks, three inches i'll diameter and tive-six-
teenths of an inch thick, and supported on
| rings or collars After the explosion it was
found that the ordinary dynamite had III
dented its disk quarter of an inch, while
the carbo-dynamite had caused a concavity
seven-sixteenths of an inch deep, or three
sxteenths of an inch deeper than the other,
besides driving its supporting ring deeply
into the ground.
In order to show that in using carbo-
dynamite in underground work 10 noxiOus
| fumes arise, an experiment was made in a
tunnel half a mile long constructing for The
Rfondda and Swansea bay railway. When
shot had been fired in the rock at the
beading of the tunnel with one pound of
S,bo-dynamite no deleterious fumes could
lie oct, cted. When, however, subsequently,
shot was fired with one pound of ordinary
dynamite noxlous vapOrs were plainly dis

will enable miners to pursue their arduous
work without injury to health, and the
advantage claimed for it, that no injurious
fumes are generated in its explosion, seems
70 be well established.
As carbo-dynamite is not affected by
moisture, not exuding or parting with its
mtro-glycerine when exposed to damp or
water, it may safely be mixed with that

inexpensive, and that its cost to the user

these latter points remain, of course, to be
| proved, but from what has been said of its
use and effect there can be no doubt that a
very formidable rival has arisen to ordi-
nary dynamite and that the introduction
oicarbo-dynamite in mining or tunneling
work Is only question of time.
