"The tide flows down, the wave again Is vocal in its wooded walls; My deeper anguish also falls, And I can speak a little then." It is at the Bargain Pool, past the pretty village of Llandogo, that the Severn tide is first met. Now, although the scenery is sublime, there can be no gainsaying that the rise and fall of the tide mars the beauty of the Wye. Instead of the clear mountain water, the stream is turbid, and at low tide the banks present great stretches of soft mud. For the first time the stream now takes on a commercial aspect, lazy barges floating up and down, and a few enterprising little steamers making their cautious way round the sharp bends.

Coming round a bend in the river one catches sight of the beautiful ruin with startling suddenness. It stands close by the waterside, on what was once a meadow stretching away from the Wye. Here the hills rise in a complete circle, and nestling in the midst of this amphitheatre is the abbey, a ruin, it is true, yet not so mutilated by the hand of Time as to make it impossible or even difficult at this day to imagine it as it stood in all its completeness and beauty. Whether Tintern, unspoiled by Time and neglect, was as impressive as it is in its decay, though the greenest of green grass now grows on the floor once trodden by the white-robed monks, and the rooks sit in a jet-black line on the top of the roofless walls--one may very well doubt. Those who have passed even a day in and about the ancient abbey will find it easy to believe that its history is one of serenity and peace. The hills that ring it round stand like a cordon of mighty giants to beat back all worldliness that would enter the charmed circle. The very air hangs heavy and still, and the river, forgetting its wild youth and stormy middle age, passes by, if one might so describe it, with bared head and hushed breath. Here for hundreds of years lived successive generations of monks, having little, wanting little, passing their days in the deepest peace and solitude; and though they have long since vanished, they have left behind them what is perhaps the finest monastic ruin in the kingdom.
