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. _FIRE SHIP._—_Proportion of combustible Stores for a Fire Ship of 150 Tons._ Nᵒ. Fire barrels, filled with composition 8 Iron chambers, to blow open the ports 12 Composition for priming, barrels 3½ Quick, match, ” 1 Curtains, dipped 48 Reeds, long, single dipped 150 ” short, { double dipped 75 { single dipped 75 Bavins, single dipped 250 The fire barrels are about 2 feet 4 inches high, and 1 foot 6 inches diameter. Each barrel must have four holes of about 6 inches square cut in its sides; and these holes must have a square piece of canvass nailed over them quite close. They are then filled with the same composition as for carcasses, and 4 plugs of about 1 inch diameter and 3 inches long, and well greased, are thrust into the top, and then left to dry. When dry, these plugs are taken out, and the holes driven with fuze composition, and quick match at the top; which goes from one hole to the other: after this the top is smeared over with mealed powder mixt up with spirits of wine. When dry again, a sheet or two of brown paper is laid over the top, and then one of the canvass covers, which is made secure by the upper hoop of the barrel. _Composition for dipping Reeds, Bavins, and Curtains._ lbs. Rosin 120 Coarse sulphur 90 Swedish pitch 60 Tallow 6 Mealed powder 12 This proportion will dip about 100 reeds and 25 bavins. Each curtain contains 1 square yard of barras. Each cover for fire barrels 1 do. of sacking. Immediately that the curtains, covers, &c. are dipped, they are to be strewed over with fine brimstone, before the composition grows cold.
