These are cases about 2¹/₂ inches long, and 1 inch diameter. Make a bottom to the case with ¹/₄ inch thickness of plaster of paris, so that it looks like a large pill box. Charge it solid, and at ³/₈ of an inch from the extremity, that is, ¹/₈ of an inch beyond the plaster bottom, round the circumference make five holes, as for saxons; run a bit of match round, connecting the holes. These, when fired, stand out at right angles, the plaster towards the spectator, so that the fire resembles a gas star, with 5 points, as in fig. 130.
