The following is the Distribution of the Depth of a Camp of Infantry or Cavalry, when the Ground permits.
If the ground on which the camp is to be formed will not, from a swamp in the rear, or any other circumstance, admit of each troop or company being formed in one row perpendicular to the front; the distribution of the front of a battalion or squadron must be more contracted than the above, and laid out as follows: Find how many perpendicular rows will be required, by dividing the number of men in the battalion or squadron by the number the ground will admit of in one row; then the number of rows being multiplied by the breadth of one in front, will give that part of the front to be occupied by the rows; and the difference between it and the whole front allowed for the battalion or squadron, will be left for the streets; which, if the streets are to be equal, must be divided by their number, to find the breadth of each; or is otherwise easily divided into streets of unequal breadths. When two guns are attached to a battalion, they are posted on the right in the following order: from the right of battalion to the center of the first gun, four yards—from this to the second gun, 6 yards.—The muzzles of the guns in a line with the serjeants’ tents.
The subaltern of artillery, if any, in a line with the subalterns of infantry.—The rear of the gunner’s tents in a line with the rear of the battalion tents.
For the proper positions for camps, see the word [Reconnoitering]; and for the encampment of a park of artillery, see the word [Park].
CARCASSES.—Composition.
| Saltpetre | 50 | parts. |
| Sulphur | 25 | |
| Antimony | 5 | |
| Rosin | 8 | |
| Pitch | 5 |
Valencienne’s composition, so called, from its having been used by the Austrians at the siege of that place, has the effect of making shells answer the purpose of carcasses after they burst:
| Saltpetre | 50 | parts. |
| Sulphur | 28 | |
| Antimony | 18 | |
| Rosin, or Swedish pitch | 6 |
This composition is cast in copper cylindric moulds of 6 inches long, and of different diameters according to the shell in which it is to be used. It must be put in along with the bursting powder in pieces as large as the shell will admit, without preventing the fuze being driven down.
