2. Battery Fascines—are made from 8 to 12 feet long, and from 10 to 12 inches thick; used for the revetement of the parapet, &c.
3. Trench Fascines—from 4 to 6 feet long, and from 4 to 9 inches thick; used at sieges.
4. Water Fascines—6 feet long, from 1 to 2 feet thick; used to cover marshy and wet situations; they must be loaded with stone to make them sink.
5. Covering Fascines—are used to form the tops of magazines or saps. They ought therefore to be composed of the strongest branches, with the addition of a few poles, that they may bear a considerable weight.
6. Sap Faggots—3 feet long, 8 inches thick.
Attentions in making Fascines—The bands must be from 10 to 12 inches asunder, of birch, hazle, or other pliant wood, well twisted. The fascines must be drawn close with a choke rope, previous to being tied.
In laying the wood to form the fascines, the shortest and smallest pieces should be laid inside. Three men are usually employed at each trestle, with two to collect the stuff.
In general a saucisson of 18 feet may be finished at each trestle in half an hour.
Birch and fir are the bell woods for this work.
Fascines are sometimes bent so as to coincide with the angles of the battery. The Prussians double some of the fascine stuff, so as to make a loop at the end of the fascine, which being laid over one another at the corners, and a stake driven through the loops, are very strong.
