MAKING FIREWORKS
1T HAS DEVELOPED INTO A BIG
AMERICAN INDUSTRY.
And 1t Has All Been Worked Out
from the Ancient Chinese Fire
cracker - How They
Are Made.

The manufacture of fireworks has
developed from an imitation OF the
Chinese firecracker to an industry of
vast proportions in the United States.
Also from the humble and compare
tive harmless cracker, the product has
been developed along the most com.
pick yet scientific lines until the mas
ter of ceremonies at full dedged mod
ern fireworks exhibit must needs be
man with a comprehensive knoWl-
edge of the explosives he is handling.
The Chinaman, having invented
gunpowder a few thousand years be-
fore it came into use in the western
world, invented the firecracker so long
ago that the incident of it's birth has
been lost in the shuttle of history, but,
| curiously enough, the Chinaman in
this respect has stood at the initial
point of development, as he has in all
else that pertains to his life. He still
makes good firecrackers, but they are
of the same model and power as he
has used for hundreds of years. The
American, having stolen the idea, pro-
ceeded to develop it along lines truly
indicative of the American character
| -hamboyant, pyrotechnic and loud.
The Chinese cracker is a small affair,
considerably more so than the crack
er to buy which the small boy toiled
in the gray dawn carrying water to
the elephant, but at Chinese New
Years and other festival times a
string of their firecrackers suspended
from the end of a bamboo pole will
eXplode-every one of them-and
there will be no "sizzlers" nor blanks
found in the string. Which goes to
show that the handmade Chinese
western methods of cheap machine
manufacture have not invaded the
cradle of the firecracker.
But as all things American have de-
veloped to prodigious proportions,
leaving in the past the memory of sim
| plicity, so the firecracker of history
each year finds smaller place in the
demonstrations of America. Instead
there have come the rocket, the bomb,
the set piece and the appliances for
pouring forth torrents and volcanoes
of multi-colored fire. 1t is the manu-
facture of these goods that has grown
to such size and commercial conse-
quence.
The preliminary in the manufacture
of nearly all fireworks is the making
of the case. The quality of paper
varies from the commonest straw
| board to the finest bank note paper.
Cases for skyrockets require a fine
grade of paper called rope board. The
paper is first pasted and then rolled
| over a mandrel. The drying process
takes four or five days and the case
then is ready for for charging. They
vary from two to 20 inches in length
and from one-quarter Of an inch to two
inches in diameter. The loading Of
| skyrockets, up to the last four or five
years, has been done by hand, but the
machine now takes the place of the.
hand loader. A spindle placed in the
center of the case causes a cavity as
| the material is packed in around it.
The materials are scooped in, ham,
mered down until it is of rock-like
| hardness and then the spindle is with
| drawn. When the rocket is fired the
| large surface of material in the spin
die cavity catches fire at once. caus-
