The Restoration came, and changed every thing. The Scots regained their independence, and soon began to find that independence had its discomfort as well as its dignity. The English parliament treated them as aliens and as rivals. A new Navigation Act put them on almost the same footing with the Dutch. High duties, and in some cases prohibitory duties, were imposed on the products of Scottish industry. It is not wonderful that a nation eminently industrious, shrewd, and enterprising, a nation which, having been long kept back by a sterile soil and a severe climate, was just beginning to prosper in spite of these disadvantages, and which found its progress suddenly stopped, should think itself cruelly treated. Yet there was no help. Complaint was vain. Retaliation was impossible. The Sovereign, even if he had the wish, had not the power, to bear himself evenly between his large and his small kingdom, between the kingdom from which he drew an annual revenue of a million and a half and the kingdom from which he drew an annual revenue of little more than sixty thousand pounds. He dared neither to refuse his assent to any English law injurious to the trade of Scotland, nor to give his assent to any Scotch law injurious to the trade of England. The complaints of the Scotch, however, were so loud that Charles, in 1667, appointed Commissioners to arrange the terms of a commercial treaty between the two British kingdoms. The conferences were soon broken off; and all that passed while they continued proved that there was only one way in which Scotland could obtain a share of the commercial prosperity which England at that time enjoyed, [274] The Scotch must become one people with the English. The Parliament which had hitherto sate at Edinburgh must be incorporated with the Parliament which sate at Westminster. The sacrifice could not but be painfully felt by a brave and haughty people, who had, during twelve generations, regarded the southern domination with deadly aversion, and whose hearts still swelled at the thought of the death of Wallace and of the triumphs of Bruce. There were doubtless many punctilious patriots who would have strenuously opposed an union even if they could have foreseen that the effect of an union would be to make Glasgow a greater city than Amsterdam, and to cover the dreary Lothians with harvests and woods, neat farmhouses and stately mansions. But there was also a large class which was not disposed to throw away great and substantial advantages in order to preserve mere names and ceremonies; and the influence of this class was such that, in the year 1670, the Scotch Parliament made direct overtures to England, [275] The King undertook the office of mediator; and negotiators were named on both sides; but nothing was concluded.
