And as the opening of the century may be considered notable for the first mention of _Usquebagh_, so its close is memorable for the first employment of fire-arms. In the year 1489, according to Anglo-Irish Annals, "six hand guns or musquets were sent to the Earl of Kildare out of Germany," which his guard bore while on sentry at Thomas Court—his Dublin residence. But two years earlier (1487) we have positive mention of the employment of guns at the siege of Castlecar, in Leitrim, by Hugh Roe O'Donnell. Great guns were freely used ten years later in the taking of Dungannon and Omagh, and contributed, not a little to the victory of Knock-doe—in 1505. About the same time we begin to hear of their employment by sea in rather a curious connection. A certain French Knight, returning from the pilgrimage of Lough Derg, visiting O'Donnell at Donegal, heard of the anxiety of his entertainer to take a certain Castle which stood by the sea, in Sligo. This Knight promised to send him, on his return to France, "a vessel carrying great guns," which he accordingly did, and the Castle was in consequence taken. Nevertheless the old Irish, according to their habit, took but slowly to this wonderful invention, though destined to revolutionize the art to which they were naturally predisposed—the art of war. The dwellings of the chiefs, and of the wealthy among the proprietors, near the marches, were chiefly situated amid pallisaded islands, or on promontories naturally moated by lakes. The houses, in those circumstances, were mostly of framework, though the Milesian nobles, in less exposed districts, had castles of stone, after the Norman fashion. The Castle "bawn" was usually enclosed by one or more strong walls, the inner sides of which were lined with barns, stables, and the houses of the retainers. Not unfrequently the thatched roofs of these outbuildings taking fire, compelled the castle to surrender. The Castle "green," whether within or without the walls, was the usual scene of rural sports and athletic games, of which, at all periods, our ancestors were so fond. Of the interior economy of the Milesian rath, or dun, we know less than of the Norman tower, where, before the huge kitchen chimney, the heavy-laden spit was turned by hand, while the dining-hall was adorned with the glitter of the dresser, or by tapestry hangings;—the floors of hall and chambers being strewn with rushes and odorous herbs. We have spoken of the zeal of the Milesian Chiefs in accumulating MSS. and in rewarding Bards and Scribes. We are enabled to form some idea of the mental resources of an Anglo-Irish nobleman of the fifteenth century, from the catalogue of the library remaining in Maynooth Castle, in the reign of Henry VIII. Of Latin books, there were the works of several of the schoolmen, the dialogues of St. Gregory, Virgil, Juvenal, and Terence; the Holy Bible; Boethius' Consolations of Philosophy, and Saint Thomas's Summa; of French works, Froissart,
