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 aiong the most com
pick yet scientific lines until the mas

The Chinaman. having invented

world, invented the firecracker so long
ago that the incident of its 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

indicative of the American character
--flamboyant. pyrotechnic and loud.
The Chinese cracker is a small affair,
considerably more 80 than the crack
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 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
article is still honestly made and that
western methods of cheap machine
manufacture have not invaded the
cradle of the firecracker.

veloped to prodigious proportions.

The preliminary In the manufacture
OF nearly all fireworks Is the making
of the case. The quality of paper
varies from the commonest straw.

Cases for skyrockets require fine
grade OF paper called rope board. The
paper Is first pasted aud then rolled
over mandrel. The drying process
takes four or Ave days and the case
then is ready for for charging. They
vary from two to 90 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
