As the eye passing upwards reads
"Nitro-glycerine factory, very danger

use for which the building is intended
and the necessity for watchful care over
it is apparent. At the door were seen
lying iron casks sheeted inside with lead
and in these casks are imported the pure
glycerine and mixed acids used in the

by machinery to the upper story
and dumped into a mixing tub,
in which the mixing blades are
moved by crank turned by a man
who is stationed in tight box and has
in front of him a thermometer. As the
glvcerine runs into the acid, the vapor
is engendered in which life is scarcely
supportable, hence the man turning the
crank is stationed in close box. The
acid and glycerine in their admixture
rapidly heat, and the compound has to
be toned down by cold water or ice,
the greatest watchfulness is necessary
ut this point, rs the heat is allowed to
run up to eighty degrees, and the nitro
glycerine explodes at ninety degrees,
there remains but ten degrees of heat
between the known and eternity, or, rs
the manager remarked, if the heat was
allowed to run up to ninety degrees they
would not have time to pucker their
mouth to say good-by.

work is going on, strangers are never

manufactured has an explosive force ten
times greater than thai of blasting pow

although dynamite is understood to be
extremely dangerous to handle, it is

as would be the case were the substance

The cartridges are made TO hold from
