These Dangerous and Sensitive aPlay-

Oyer 500 children have been hurt or
perhaps crippled for life in the last five
years from playing with blasting caps.
II this had Unopened at one time what

world HIT because the accidents are
spread all over the country and happen
at the rate of only about ten a month
nothing is done by the authorities. In
deed. nothing can be done except to ed
ncate the whole population to realize
how dangerous these exceedingly use
fnl things are when they are out OF
their proper place. And what dread
FIJI thing it is going through life Grip
pied or blinded for want of little care
and knowledge.
Boys often play In and around quar-
ries on Sundays and sometimes pick
up stray caps and start to investigate
them. 1t is the rarest thing that they
ever do this without getting hurt.
They perhaps know they are danger
GUS and that a spark or blow win ex-
pI0de them. but they do not realize
how sensitive they are. how violent

tots. and because the blasting caps are
called Dy this name it Is natural to
think that the TWO articles belong to
the same family. They may, but they
! bear about the same resemblance to
each other that a hungry man eating
tiger does to the gentle pussy cat.
There are lots of ways Of getting
crippled by exploding blasting caps be-
sides hitting them with hammer and
putting them in the fire. Extracting
the contents with pin distributes un-
told fingers; holding lighted match
under them or thrusting the flaming
end into the cap gets immediate ac-
ton. In the mines and quarries even.
where the men who have to use blast
ing caps every day ought to know bet
ter. there are plenty of mangled hands
and punctnred hides as the result of
crimping caps on fuse with a jack
knife, pointed nail or any tool that's
handy.
Many miner has blown a hole
through his face In biting the cap on
the fuse and others have filed them
selves with copper or have, been killed
outright by the sparks from their hat
lamps or pipes dropping in an open
box OF caps. j, Lots of blasters continue
to bite the caps on the fuse and think
that because they havenever exploded
them they never will, but some day
they will bite the business end and
lose something besides teeth. 1t is
much easier and lots safer to use the
crimper. tool made for the purpose.
Accidentally stepping on cap will
often spoil a perfectly good foot.

they are applied.

the most sensitive and about the most
impulsive explosive In common use
Blasting caps contain anywhere from
fifteen to twenty grains.of it. Primers
for firearms cartridges usually contain
not more than one grain. That's what
the hammer or firing pin of a gun or
pistol hits to ignite the powder in the
work the other way. The powder from
the fuse ignites the illuminate In the

The explosion of the illuminate is so
exceedingly quick that the flying par

caps will blow a beautiful square hole
right through a two inch oak plank
One cap will blow child's hand off

The point to be remembered is that
when blasting cap goes of it does
great damage locally. There is no es-
Gaping It's effects. Among all the 600
or more accidents reported from playing
with blasting caps there are only two
or three in which somebody was not
hurt
Electric blasting caps are just as
