tents of the bowl may be emptied into
large tank which is always filled
with water.
Paddles continually stir the mixture

This building was declared by Mr.
O'Brien to be the most dangerous of
the whole plant The watts and cylin-
ders are made of lead. which is the on
ly substance which will withstand the
action of the acids. The most promi-
nent feature OF the equipment is lit

is combined with the wood pulp. These
mills resemble the ancient stone mills
Of South America with the difference
that they do not grind but simply mix
the dynamite TO the right consistency
for the next process, that of filling the
paper shells. a wonderful elevated
railroad system brings the ingredients
10 their mixer. The cars are automa-
tically controlled and are very accu-

nitro glyoerine with the wood pulp is

for packing
Throughout the plant the most mod
crn and up-to-date methods OF manu-
featuring are used. The acids. glyce-
rine and ro-glycerine are sent from
one building to another by compressed
air. Electric power is used except in
instances where steam is considered
more consistent and safer.
Engineer O'Brien has sunk hydrau-
lie wells which furnish water for the
whole plant. Great precautions are
taken against danger Of fire and hoses
are always connected with the hyd-
rants. The electric lights are enclosed
in double glass globes and in glass
cases in the walls. The wires are en-
closed In lead pipes TO protect them
from the fumes. The plant has it's
own electric plant, makes its own
steam and compressed air. has erected
several large concrete buildings whore
the company makes its own acids and
has its own railroad equipment. The
materials used in the manufacture Of
the acids are secured from all parts
OF the world and this manufacture is n
very important part of the works.
AS soon as the plant begins opera
tons large number OF men will find
employment there. Dynamite will be
the only product of the plant and the
nearness TO the mines OF the copper
country, and the admirable facilities
for shipping, both by rail and by wa
ter, should make the venture a big
success,
