LIGHTS, LONG (OR STEVENS’).
The composition is similar to that for blue lights. The cases are made of brown paper, and are of the same diameter as the one-pound signal rocket. The case is cut to the length of 9·75 inches, one end being perforated at an inch from the bottom to allow a wooden pin to pass through it, for the purpose of attaching the handle to the case.
Two coats of paint are given to the cases.
A long light will burn five minutes.
LIGHTS, SIGNAL (BOXER’S)
This is similar to the Light, long, but has only one inch of composition.

Four pounds of the gunpowder are mixed into a thin paste with a portion of the gum-water boiling, in this the cotton is then immersed. Six pounds of gunpowder made into a stiff paste, with the remainder of the gum-water, is spread on the top of the match, which is afterwards reeled off, the remaining two pounds of powder being sifted on the match while on the reel, and some of the stiff paste being held in the hand through which the match passes.
