If the country round Boyle Abbey cannot be said to be very interesting or beautiful, the place where the ruins stand is charming. They rise from the banks of the Boyle river, the first large tributary of the Shannon. The river rushes under the very walls of the monastery with a rapid current, and at its highest flood it is generally as clear as crystal, for it rises in, or at least flows through, Loch Ui Gara, which is only a few miles from Boyle, and its waters are filtered in that lake before they reach Boyle. And here it may not be out of place to say that the generally clear waters of most of the rivers of Ireland add greatly to the beauty of its scenery. Scotch rivers are also generally clear, and the reason they are clear is the reason why the Irish rivers are clear, and that is, because they are filtered in the lakes through which they generally flow. A limpid river is one of the most beautiful things in nature, but a river of dirty water would not be beautiful if it flowed through the Garden of Eden. Almost all rivers that are not filtered by passing through lakes are sure to be dirty. For this reason the St Lawrence may be said to be the only one of the great American rivers the waters of which are clear. To know what an abomination a river of dirty water is, one should see the Missouri. The river that rushes past the ruins of Boyle Monastery is not only clear but limpid. Its pure, rushing waters are one of the principal attractions in the vicinity of the ruins. The ruins of Boyle Abbey are very fine. The monastery was a large one, one of the largest in Ireland, and was surrounded on almost every side with extensive gardens. The walls of many of those gardens still remain, and seem as sound as they were when first built. The ruins of the Monastery, and the ruins of its adjoining buildings, are covered with the most luxuriant growth of ivy to be seen on any ruins in Ireland. The thickness of its stems, and the size and deep green of its leaves, are remarkable. This extraordinary growth of ivy must eventually tumble down the walls. It may preserve them for a time, but will destroy them in the long run. But without its ivy and its limpid river, the ruined Monastery of Boyle, grand and interesting as it is, would lose a great deal of its attractions.
