Shells, made by uniting two hemispheres, containing powder, and furnished with balls and a fuse, are also a destructive weapon of the same character.
Sec. XXXV. Of Incendiary Rope.
We have mentioned, under the head of Tourteaux, or tarred links and fascines, the compositions made use of for these preparations. The composition for incendiary rope is as follows:
| Sulphur | 12 | parts |
| Saltpetre | 6 | —— |
| Rosin | 2 | —— |
| Camphor | 2 | —— |
| Meal-powder | 4 | —— |
| Grained powder | 2 | —— |
The rosin, sulphur, camphor, and saltpetre are melted, and mixed thoroughly together, and the kettle, which contains them, is removed from the fire; the gunpowder is then added, and intimately blended.
The mixture is again heated, and the rope is then immersed in it, and suffered to remain until it has imbibed sufficiently. It is then taken out, and allowed to cool.
After this operation, we melt, in a separate kettle, the following substances:
| Rosin | 4 | parts. |
| Pitch (or tar) | 4 | —— |
| Mutton suet | 2 | —— |
When they are melted, and mixed, the rope previously prepared as above, is thrown into the mixture, and then removed and hung up.
