The cup of woe was not yet full. In England, with revolution principles, the mercantile party had mounted to power, and commerce in those days was everywhere ridden by the fallacy of protectionism, which killed the only good articles in the Treaty of Utrecht, those opening free trade with France. Ireland, the English protectionist regarded as a foreign country, and a particularly dangerous enemy to his interest. The cattle trade having been killed by the act of Charles II., the Irish had taken to the export trade in wool and to woollen manufactures. The wool grown on Irish sheepwalks was of the finest, and was eagerly purchased by France and Spain. This industry also English monopoly killed by prohibiting the exportation of wool to foreign countries and the importation of Irish woollen goods into England. The same jealous rapacity seems to have successively killed or crippled the cotton industry, the glove-making industry, the glass industry, the brewing industry, to each of which Ireland successively turned; English greed being bent, not only on excluding the Irish competitor from its own market, but on keeping the Irish market to itself. Ireland had been promised free enjoyment of the linen trade, which Strafford had encouraged by promoting the growing of flax while he discouraged the wool trade; yet even this promise Irish financiers could accuse England of eluding by tricks of the tariff. England needing more bar iron than she could produce, the importation of bar iron from Ireland was allowed; but the consequence was a consumption of timber for smelting which denuded Ireland of her forests. Cromwell's union would have secured to Ireland exemption from the disabilities of the Navigation Laws. The Restoration imposed them. They killed her trade with the colonies and killed her shipping interest at the same time. "The conveniency of ports and harbours," said Swift, "which nature has bestowed so liberally upon this kingdom, is of no more use to us than a beautiful prospect to a man shut up in a dungeon." In all this Ireland was treated as a colony, meant only to be a feeder to the imperial country. But her position was worse than that of the colonies, in which commercial restrictions generally were loosely enforced, and which, when strict enforcement was attempted by Grenville, rose in arms. The colonies, moreover, were regarded with pride and affection. Popish Ireland was regarded with contempt and hatred. The lawful trade in wool with foreign countries England had suppressed. Its place was partly taken by a smuggling trade, for which the inlets of the Irish coast afforded the best of havens, and which had the people everywhere for confederates. Thus, in every line, religious, social, educational, and commercial, the Irishman found the law his inveterate enemy. Could he fail to be an inveterate enemy of the law?
