The old, long bridge is a structure of stone, and of considerable consequence. It was erected in Ireland's memorable year, 1798, and near this place one of her most important battles was fought, which ended to her disadvantage, and resulted, in 1801, in the surrender of her power, and the establishment of English rule. It is too much to expect that England, who so long ago established its authority in India, and in our time in Cyprus, thousands of miles away, should resist the temptation of subjugating a land so indefensible as Ireland, which lay at her very door. The bridge having been built in her last great battle year, a stone slab in the parapet records the fact. Here are the inevitable barracks. They are of stone, three stories high, and very extensive. There were evidences of military rule in every place yet visited. The soldiers are all young. None are over thirty years of age, and many not more than eighteen. All are stout and robust, and each is a picked man. The uniform coats are red, with gilt buttons, the pants are a dark plaid; they look dandyish. These men are the best physique of the nation, and, as a whole, put to a bad use. They are always to be found on the street, either singly, by twos, or in squads, each with a switch-cane, said to be furnished by the government. The police are English, for no Irish person is trusted, and they are finely dressed in dark clothes. They are very civil and gentlemanly, and, like the soldiers, are picked men. Save on a single occasion in Dublin, we saw no disturbance of any kind, nor any service rendered by the police. What interested us most was an old tower on this main thoroughfare, situated at the extreme end of the quay on the land side, and just out to the sidewalk line, in close contiguity with the surrounding buildings. It is fifty feet high, and about thirty-five feet in diameter, and is built of irregular ledge stone, of a dark gray or brownish color; is very plain, as far as a projection near the top, of a few inches; above this it is continued up plain some two or three feet higher, having a conical roof which comes down apparently inside of the stone work. There is a single door in the first story. Just above this, to the left, is a stone tablet, about two and a half feet wide and five feet high, with pilasters and pediment top,--the whole much like a dormer window. The inscription is as follows:-- IN THE YEAR 1003 THIS TOWER WAS ERECTED BY REGINALD THE DANE. IN 1171 IT WAS HELD AS A FORTRESS BY STRONGBOLD, EARL OF PEMBROKE. IN 1463 BY STATUTE 3D, EDWARD IV, A MINT WAS ESTABLISHED HERE. IN 1819 IT WAS REEDIFIED IN ITS ORIGINAL FORM AND APPROPRIATED TO THE POLICE ESTABLISHMENT BY THE CORPORATION BODY OF THE CITY OF WATERFORD. RT. HON. SIR JOHN NEWPORT, BT., M.
