In making a fascine, straight twigs about the thickness of a man's finger are laid side by side, and firmly compressed together by a strong rope or chain attached to the extremities of two levers.

While held in this position the twigs are firmly bound together by withs or cords.

Fascines are used in constructing trenches, batteries, &c., and for filling up wet ditches.
The _sap-fagot_ is a strong fascine about ten inches in diameter and two feet in length, with a picket inserted through the middle.

It is used in the double sap in connection with gabions.
_Sand-bags_ are usually made of coarse canvass.

When filled with earth they are some six or eight inches in diameter, and from eighteen inches to two feet in length.
