From the day in 1796 when Capt. Moriarty, press-gang-officer at Cork, reported the arrival of the long-expected Brest fleet off the Irish coast, [Footnote: _Admiralty Records_ 1. 1621--Capt. Crosby, 30 Dec. 1796.] the question how best to defend from sudden attack so enormously extended and highly vulnerable a seaboard as that of the United Kingdom, became one of feverish moment. At least a hundred different projects for compassing that desirable end at one time or another claimed the attention of the Navy Board. [Footnote: _Admiralty Records_ 1. 581--Admiral Knowles, 25 Jan. 1805.] One of these was decidedly ingenious. It aimed at destroying the French flotilla by means of logs of wood bored hollow and charged with gunpowder and ball. These were to be launched against the invaders somewhat after the manner of the modern torpedo, of which they were, in fact, the primitive type and original. [Footnote: _Admiralty Records_ 1. 580--Rear-Admiral Young, 14 Aug. 1803, and secret enclosure, as in the Appendix. The Admiral's "machine," as he termed it, though embodying the true torpedo idea of an explosive device to be propelled against an enemy's ship, was not designed to be so propelled on its own buoyancy, but by means of a fishing-boat, in which it lay concealed. Had his inventive genius taken a bolder flight and given us a more finished product in place of this crudity, the Whitehead torpedo would have been anticipated, in something more than mere principle, by upwards of half a century.] Meantime, however, the Admiralty had adopted another plan--Admiral Popham, already famous for his improved code of signals, its originator. On paper it possessed the merits of all Haldanic substitutes for the real thing. It was patriotic, cheap, simple as kissing your hand. All you had to do was to take the fisherman, the longshoreman and other stalwarts who lived "one foot in sea and one on shore," enroll them in corps under the command (as distinguished from the control) of naval officers, and practise them (on Sundays, since it was a work of strict necessity) in the use of the pike and the cannon, and, hey presto! the country was as safe from invasion as if the meddlesome French had never been. The expense would be trivial. Granting that the French did not take alarm and incontinently drop their hostile designs upon the tight little island, there would be a small outlay for pay, a trifle of a shilling a day on exercise days, but nothing more--except for martello towers. The boats it was proposed to enroll and arm would cost nothing. Their patriotic owners were to provide them free of charge.
