Colonel Ford expressed a desire to take the clock home with him to show it to his wife. On his way, the jolting of the cab was sufficient to partially release the winder, and the hammer of the pistol descended during the night. Of course, the cartridge and dynamite had been previously removed by the Inspectors. Before referring at length to the next important event in the history of dynamiters for the year 1884, we would remind the reader that we have only dealt in detail with two types of infernal machine: the clock system, which may be set in advance to act some hours later; and the burning fuse, which was employed in some of the earlier explosions alluded to. The infernal machine found at Cork and preserved at New Scotland Yard shows this method of working very clearly (Fig. 14). It is a wooden box about a foot square and separated into divisions. One compartment is fitted with clockwork, to which a fuse is attached and which passes through to the other part of the box filled with gunpowder. This box would hold about 8lb. of powder. When the lid is removed the clockwork starts, the fuse is fired, and the gunpowder explodes. A fuse is a series of strands of hemp with a column of gunpowder running through. There are many varieties, and every manufacturer has a special mark on the fuse he makes, so that the authorities can always trace it. We lit a fuse and found that it burnt at the rate of a yard a minute; it can, therefore, easily be adjusted to any time required. We now, however, come to the most deadly of all weapons used by dynamiters--the bomb, which explodes instantly on falling. These bombs--as the shrapnel shell, used in artillery--can only be designed for one purpose, the destruction of human life: they are essentially man-killing infernal machines. On April 11th, 1884, three metal bombs, containing dynamite, were found in the possession of Daly, at Birkenhead, who was subsequently sentenced to penal servitude for life. [Illustration: FIG. 14.--INFERNAL MACHINE FOUND AT CORK.] The old-fashioned bomb was of a shape resembling an egg, with nipples like gun nipples and percussion caps. It was weighted at one end to insure its falling on the point intended. The Barcelona bomb was spherical, but similarly fitted with nipples. This is the Orsini type.
