Railways have proved among the greatest, as well as the latest, of the agents of destruction. In our island various cherished antiquities have been often most unnecessarily swept away in constructing these race-courses for the daily rush and career of the iron horse. His rough and ponderous hoof, for example, has kicked down, at one extremity of a railway connected with Edinburgh (marvellously and righteously to the dispeace of the whole city), that fine old specimen of Scottish Second-Pointed architecture, the Trinity College Church; while, at the other extremity of the same line, it battered into fragments the old Castle of Berwick, a fort rich in martial and Border memories, and a building rendered interesting by the fact, that in connection with one of its turrets there was--at the command of Edward I. "the greatest of the Plantagenets," (as his latest biographer boastfully terms him)--constructed, some six centuries ago, a cage of iron and wood, in which he immured, with Bomba-like ferocity, for four weary years, a poor prisoner, and that prisoner a woman--the Countess of Buchan--whose frightful crime consisted in having assisted at the coronation of her liege sovereign, Robert the Bruce. In the construction of the Edinburgh and Glasgow Railway the line was driven, with annihilating effect, through the centre of the old and rich Roman Station on the Wall of Antoninus at Castlecary. Some years ago, as I passed along the line, I saw the farmer in the immediate neighbourhood of this station busily removing a harmless wall,--among the last, if not the very last remnants of Roman masonry in Scotland. The largest stone circle near the English Border--the Stonehenge or Avebury of the north of England--formerly stood near Shap. The stone avenues leading to it are said to have been nearly two miles in length. The engineer of the Carlisle and Lancaster railway carried his line right through the very centre of the ancient stone circle forming the head of the chief avenue, leaving a few of its huge stones standing out on the western side, where they may be still seen by the passing traveller about half a mile south of the Shap station. If the line had been laid only a few feet on either side, the wanton desecration and destruction of this fine archaic monument might have been readily saved. Railway engineers, however, and railway directors, care far more for mammon and money than for mounds and monoliths.
