=The Manufacture of Firecrackers in China.=--There were exported from
China during the year ending June 30, 1897, 26,705,733 pounds of
firecrackers, all from the province of Kwantung. The exports, however,
represent only a small portion of the number manufactured, as the use
of the cracker is universal all over China. They are used at weddings,
births, funerals, at festivals, religious and civil, and in fact on
all occasions out of the ordinary routine. The United States consul
general at Shanghai gives the following account of the industry: There
are no large factories; the crackers are made in small houses and in
the shops where they are sold. In making them only the cheapest kind
of straw paper is used for the body of the cracker. A little finer
paper is used for the wrapper. A piece of straw paper, nine by thirty
inches, will make twenty-one crackers an inch and a half long and a
quarter inch in diameter. The powder is also of the cheapest grade,
and is made in the locality where used. It costs about six cents per
pound. For the fuse a paper (called "leather" in Shanghai) is used,
which is imported from Japan, and is made from the inner lining of the
bamboo. In other places a fine rice paper is used, generally stiffened
slightly with buckwheat-flour paste, which the Chinese say adds to its
inflammability. A strip of this paper one third of an inch wide by
fourteen inches (a Chinese foot) long is laid on a table, and a very
little powder put down the middle of it with a hollow bamboo stick. A
quick twist of the paper makes the fuse ready for use. The straw paper
is first rolled by hand around an iron rod, which varies in size
according to the size of cracker to be made. To complete the rolling a
rude machine is used. This consists of two uprights supporting an axis
from which is suspended, by two arms, a heavy piece of wood, slightly
convex on the lower side. There is just room between this swinging
block and top of the table to place the cracker. As each layer of
paper is put on by hand, the cracker is placed on the table and the
suspended weight is drawn over the roll, thus tightening it until no
more can be passed under the weight. For the smallest "whip" crackers,
the workman uses for compression, instead of this machine, a heavy
piece of wood fitted with a handle like that of a carpenter's plane.
In filling crackers, two hundred to three hundred are tightly tied
together in a bunch; red clay is spread over the end of the bunch, and
forced into the end of each cracker with a punch. While the clay is
being treated a little water is sprayed on it, which makes it pack
closer. The powder is poured in at the other end of the cracker. With
the aid of an awl the edge of the paper is turned in at the upper end
of the cracker, and the fuse is inserted through this. The long ends
of the fuses are braided together in such a way that the crackers lie
in two parallel rows. The braid is doubled on itself, and a large,
