Saucissons.
7. Saucissons.—These differ only in form from the foregoing articles; till lately no distinction was made between them, nor (in our opinion) ought any to exist, but the French Artists have thought proper to give them the above name from the supposed resemblance they bear to a sausage.
The cases of Marroons are made cubical, those for the present articles are made cylindrical, and in proportion must be about four times their exterior diameter in length; their diameters may be from one to two and a half or three inches, and their cases increasing in strength as their dimensions.
The cases must be choaked or pinched at one end after the manner of rockets, and tied quite close; and afterwards the former, on which they are rolled, should be pressed hard upon the bottom to make it smooth, and to take out the wrinkles left by the choaking; the former, or interior diameter, should not exceed one half of the exterior diameter of the case.
The cases being thus prepared, they are to be filled with coarse powder one diameter, and one fourth high, and the rest of the paper must be folded down tight upon the powder; then bind them tight in every direction with strong packthread dipped in glue, and they are then left to dry as before.
They may be rendered luminous, and the match applied in the same manner as to Marroons.
Batteries of Marroons &c.
Batteries of Marroons, &c.—These, it has been said, if well managed, will keep time to a march, or a slow piece of music. They must indeed be well managed to do so; I have (with care) made several trials, but in neither was I fortunate enough to produce that uniformity in their intervals, as to mark correctly their commencement of each bar of the music; which, if they do not, they fail entirely as to this property. But, however, much effect may be produced by these noisy pieces by arranging them on several stands, with a number of cross rails, on which they are to be nailed, and connected together by means of leaders &c. of different lengths, according to their distance asunder, observing to use the large and small marroons and saucissons in order to produce a greater variety in the reports, which during the exhibition of other articles is their chief purpose.
A Battery with the leaders complete is represented in [Fig. 19].
