Leader Pipes.

These are for piping quickmatch; they are rolled exactly like pinwheel pipes, on wires of different thickness, to suit the size of the match. They must be large enough to admit the match easily, without much pushing, which would break it; otherwise, the more nearly they fit the match, the more rapidly it blows through. The fire is conveyed from the tail of one case to the mouth of another, by a short piece of pipe, d, fig. 80, with the match projecting at both ends; when the fire has to be conveyed to two other cases at once, a fresh bit of piping is slipped on, and the match left exposed, as at a; or a piece is cut out of the side, as at b; each end should be bent into a hook, as at c, to prevent its slipping back. Wheel cases are to be enveloped by rolling a piece of double-crown twice or thrice round them, two inches longer than the case, as fig. 82, shown by the dotted lines. Suppose you have six wheel cases ready charged; lay six pieces of double-crown flat before you, and work them back with the thumbnail, as before described; paste the 6 edges; lay the 6 wheel cases in a row, side by side, and draw the paste brush across the middle, as if pasting your knuckles; then roll one in each envelope, so that it projects an inch at each end. Put the leader pipe in, and tie it with a piece of carpet thread, thin twine, or waxed yellow flax or hemp, as at fig. 83. To join one pipe to another, to lengthen it; suppose you have a piece of match 40 inches, long, and two pipes of 20 inches each. Slip both the pipes on the match, so that they touch in the middle; take the end of one, so touching, gather it round the match; pinch the end of the pipe tapering, push it into the other, and bind a piece of pasted paper round, to secure the joint. In cutting a matched pipe straight across, of course the match inside gets cut flush; do not leave it so, but, with a pair of pointed scissors, cut away a quarter of an inch of the pipe all round, and bend the exposed match, as at c, fig. 80, before putting it into the envelope of the case. Besides a strong pair of pointed scissors, a small pair, 3 inches long, with rounded ends, to carry constantly in the waistcoat pocket, will be found convenient for many purposes.


[MAROONS.]

Take 3 inches of a 68 or 38 rocket case. Fix, in one end, a cork, half an inch long; put in 2 inches of F grain powder; on this, another cork. Wind string tightly round it, lengthwise, 6 or 8 folds, side by side; bend it to a right angle, and wind 6 or 8 more folds; and so on, till covered; then wind crosswise; and again, at right angles, as in fig. 74. Dip it into melted glue, and put by to dry. When dry, make a bradawl hole through one part, to reach the powder. Make sure of this, by inverting it, and letting a little drop out. Insert a short port-fire, having a piece of match at the bottom, and touch-papered at the top.
