It was the peculiar structure of the English constitution, during this century and a half of prosperity and glory, that produced so remarkable a uniformity in the objects of the national policy. These objects were pursued alike by the Republicans and the Royalists; by the Roundheads and the Cavaliers; by the Whigs, during the seventy years of their rule that followed the Revolution, and the Tories, during the sixty years that succeeded the accession of George III. The policy was that of _protection to all the national interests, whether landed, commercial, colonial, or manufacturing_. Under this system they all grew and prospered, _alike and abreast_, in the marvellous manner which the pencil of Macaulay has sketched in the opening of his History. It was hard to say whether agriculture, manufactures, colonies, or shipping throve and prospered most during that unique period. The world had never seen anything like it before: it is doubtful if it will ever see anything like it again. Under its shelter, the various interests of the empire were knit together in so close a manner, that they not only all grew and prospered together, but it was universally felt that their interests were entirely dependent on each other. The toast "The plough, the loom, and the sail," was drunk with as much enthusiasm in the farmers' club as in the merchant's saloon. As varied as the interests with which they were charged, the policy of government was yet perfectly steady in following out one principle--the protection of the _productive classes_, whether by land or water, whether at home or abroad.
