The portability and rapid construction of these boats commended them to Cæsar's military eye, and later on, in one of his Continental wars, he ordered his soldiers to make some light boats in imitation of those he had seen in Britain, in order to carry his army across a river. But, though Cæsar especially mentions these vessels, he does not say that the British of his day had no other or larger vessels. Though they made use of hides and wicker, they must have known something of wooden vessels. There is no doubt that they or their ancestors had large "dug-outs", hollowed from huge trunks of trees in the same way as Robinson Crusoe constructed his famous boat. We know this because many of these have been discovered buried in the mud of our rivers. One of them, found in the bed of the Rother in 1822, was 60 feet in length and 5 feet wide. Others have been found in Lincolnshire, Scotland, and Sussex, though none of them was nearly as long as the Rother boat. We must remember, too, that the Phoenicians had traded to Cornwall for tin, probably for centuries, and the Britons must have been familiar with their comparatively advanced types of shipbuilding. But many writers on naval matters are of the opinion that our British ancestors, whose coracles are described by Cæsar, had, even at that time, really stout and formidable ships. The reason is this. The Veneti, a race who inhabited western Brittany, and the country at the mouth of the Loire, were a kindred race, and when attacked by Cæsar received assistance from Britain. Now the strength of the Veneti seems to have been in their ships, which gave the Roman galleys considerable trouble, and it seems more than likely that the British assistance they received came in the form of a squadron of similar vessels. According to Cæsar, the ships of the Veneti "were built and fitted out in this manner: their bottoms were somewhat flatter than ours, the better to adapt them to the shallows, and to sustain without danger the ebbing of the tide. Their prows were very high and erect, as likewise their sterns, to bear the hugeness of the waves and the violence of the tempests. The hull of the vessel was entirely of oak, to withstand the shocks and assaults of that stormy ocean. The benches of the rowers were made of strong beams about a foot wide, and were fastened with iron bolts an inch in thickness. Instead of cables they used chains of iron, and for their sails, utilized skins and a sort of thin, pliable leather, either because they had no canvas and did not know how to make sailcloth or, more probably, because they thought that canvas sails were not so suitable to stand the violence of the tempests, the fury and rage of the winds, and to propel ships of such bulk and burden". It is evident that these ships were for that period quite up to date. They were strongly built and iron-bolted, and had already discarded hempen cables for iron ones.
