Nor, indeed, is it likely that the Conqueror’s fleet included many ships of a superior class or size, as we know that the great bulk, if not the whole of them, were built or collected, and fitted between the first of January and the latter end of August. Norman writers of the period state that their merchant vessels or transports were in length about three times their breadth, sometimes propelled by oars, but generally by sails: their galleys appear to have been of two sorts, the larger, occasionally called galleons, carrying in some instances sixty men, well armed with iron armour, besides the rowers. The smaller galleys, which are not specially described, doubtless resembled ships’ launches in size, but of a form enabling them to be propelled at considerable speed. Besides these, the Normans would appear to have also used, for purposes of war, small light boats covered with leather resembling those already described.[510] [Sidenote: State of trade and commerce.] It is almost as difficult to arrive at any sound conclusion with regard to the actual state of trade and commerce in England at the time of the Conquest as it is with regard to the shipping. Agriculture, which had been in so flourishing a state under the Roman government, that large shipments of corn were frequently made to the Continent, had been much neglected during the long wars between the Britons, Saxons, and Danes; and there is no instance on record of any export of grain of any sort during the whole period of the Anglo-Saxon rule. On the other hand, in unfavourable seasons, the Britons did not grow enough for themselves, though the country must have been thinly peopled, and, consequently, but too frequently suffered severely from famine. In the account of the sales of church property and of other estates, many records of which are still extant,[511] we find that land even of the best quality seldom realized a higher price than five pounds[512] of silver for a hide of land, showing that while the people must have been widely scattered few persons were in opulent circumstances.
