teries, or by the use of primer of gun-cotton
or nitroglycerne.
Fourth-In the absence Of caps etc, it can be
exploded in bore-holss by first charging with
Hercules, and then putting on top of the charge
inch or so of rifle or fine blasting powder. in
this insert the safety fuse. and lamp as usual.
IL Is much better to use caps, however.
Fifth-It can be exploded, under great pres
sure, by fire alone-say II put in bore-hole IN
iron and tight plug inserted, under other
similar circumstances, OF by fire alone, if used in
granular form, under favorable conditions
heat, and the heat slowly increased TO 5000
Fahr.
seventh-A very little can be exploded on an
anvil or stone by striking heavy blow with a
hammer, if only a very Thin layer is spread on;
but only that which comes under the force of the
hammer can explode.
If much is spread to come between the two
hard substances it will not explode.
Elghth-It can be exploded by inserting
heated bolt of iron considerably beneath the sur
face OF the mass, so as to increase the tempera-
ture of the surrounding powder TO 5000 Fair.
The effect would be the same If the powder was
placed in water and a heated bolt of iron was
thrown in amongst it. Do not thaw it by putin e
It into WAFER; but II you will persist in violating
our Instructions, don't throw pieces of hot iron
or stone in amongst it, Use common sense and
do not violate the plain instructions of wisdom
and experience.
WHAT WILL NOT EXPLODE IT.
First-It will not be exploded by fire alone in
the open air, excepting under such creum-
stances as have been before mentioned; for this
reason it is much safer to transport by any man
ner of conveyance than common powder, and it
is safe to transport as resin, turpentine var
nishes, matches, fabrics of cotton, and numer-
Gus other articles carried as ordinary merchan-
disc. Although manufacturing and shipping
constantly many thousand pounds each month
for thirteen years, we have never had any ex-
ploson in transportation,
Second-It will not explode by rough han 1liu e
or railing from any height; or the shock given it
| by railroad or other accident by the overturn-
ing or collision of cars, ETC., etc.
Third-It will not explode by any amount of
tamping with wooden tampng rod, as directed
In TINS pamphlet. Tamping with an iron or steel
tamplng bar is entirely unnecessary, especially
II the same is struck with sedge or hammer,
as is too often the foolish practice OF ignorant
persons.
Fourth 1t will not explode by being thrown,
In small quantities, on to red hot iron, onto
bright burning Goals; in which case 1t will take
fire and defiagrate rapidly without explosion
but do not presume from this thar you can bury it
in very hot sand, or the smouldering ashes of the
blacksmiths forge--in which you are liable
to raise the temperature gradually to the ex-
plOding point.
Fifth-It will not explode by placing it in a
dry vessel and setting that in another contain
ing boiling hot water, AS the heat OF WAFER.
when not under pressure, will only reach 212o
Fair. But do not presume from this that it is
safe to put the cartridges into the water to thaw
and set the thawing vessel over fire; to lay
the powder under any form, in contact with
steam heated pipes. or on, or around a steam
boiler, steam under pressure very rapidly in
creases In temperature above 212o Fair.
Sixth-It will NOT explode by carrying it inside
your shirt, or putting some cartridges in your
boots to thaw while you are at work, as a miner
would have to have very "blue Monday" to get
hot enough to explode Hercules Powder In this
way, whatever might happen in any other This
method OF thawlng is often practiced, and is
good way where small cartridges are used.
Seventh-It will not explode by being kept in
a storehOuse or magazine, for any length of
time, the composition Of Hercules renders it
impossible for any spontaneous decomposition to
take place by generating heating gases.
In short, while there numbers of other
high explosives that are strong enough and VIC
lent enough in their actions, and win do good
execution, so long as they steer clear of acct
dents by reason of dangerous Eliminates used
in their composition, by needless carelessness in
their manufacture, or by using impure material,
etc, they are, for these and many other reasons
much inferior TO Hercules Powder.
All the materials used IN the manufacture of
Hercules Powder are of the purest and best
quality that can come from the refiners' hands,
often costing us double treble those that are
less pure During the past year paid upward
of $4,000 for articles other manufacturers do
not use, to make our powder safe and of best
quality for transportation and storage.
In the manufacture of our nitro-glycerine we
use only the best dOubledstilled glycerne
which the art OF chemistry produce it be-
ing entirely free from all organic Impurities
Our works are under the most careful sgper-
intendence, and the most experienced workmen
employed.
Each one of these numerous forethOughts may
seem but little, but for years they have reward
ed US with the most unparalleled freedom from
accidents OF all kinds; and we count 1t a great
pleasure when we say, that in the great business
of mining and stump blasting, always attended
with many dangers and risks, that less sorrow
and heart-aches have been caused from MANNED
limbs and sudden deaths by accidents in using
Hercules Powder than by that of any other ex-
plosive known; and we can truly assert that no
accident has happened with 1t hut what it can be
traced TO gross carelessness and disregard of in
structious laid down for its use.
We trust that in the future, as in the past we
Will be rewarded by the liberal patronage of the
buyer and consumer.
