Another useful portion of society is to be found in our records under the name of _liberi firmarii_, or free yeomanry, the formation of which, it is presumed, may be attributed in a great measure to the ecclesiastical establishments. The clergy, from their superior education, were wiser, in their generation, than their neighbours; and instead of allowing the produce of their lands to be eaten up by hordes of idle serfs, they preferred letting them at a valuation to industrious free men, whom they encouraged by the immunities which they had it in their power to grant. These free men were generally the descendants of the clergy, the younger sons of gentlemen, or burgesses possessed of small capitals. From this judicious management, the church lands were always the best cultivated, and consequently the most productive in the country. At an early period the maritime towns were frequented by foreigners; and the productions of almost every clime were to be found in Scotland. By an Act of Alexander III.,[8] it appears that the trade of the country had rather declined during his minority; the causes of which are stated to have been, captures by pirates, shipwrecks on the coast, storms at sea, and detentions on slight grounds in various ports and places. In order, therefore, to revive the foreign commerce of the kingdom, and give the necessary security and facility to transactions with strangers, all the lieges were strictly prohibited from interfering with the said traffic, except the burgesses at the different ports. This regulation gave confidence to foreigners, by bringing them into immediate contact with a description of men, with whom reciprocal advantages would naturally beget and maintain a friendly understanding.[9] The consequence of this liberal policy was soon felt; and before the year expired, vessels from all quarters made their appearance in the Scottish harbours, willing to exchange their cargoes for the productions of the country; and in the course of a few years, Scotland exhibited a very flourishing appearance, abounding in money and wealth of every description. The Flemings, whom the English had expelled, found protection and encouragement in Scotland, and were allowed to fortify their factory at Berwick, called “The Red Hall,” under condition of their defending it to the last extremity against the enemies of that kingdom. This engagement, as will be seen, they afterwards nobly performed.
