We now pass under the great Gothic arch of Brickeen Bridge, and are in Lough Leane, or the lower lake. It has an area of five thousand acres, being five miles long, and three wide, with a very irregular shore, comprising, high and low lands, coves and inlets, a few mountain recesses, and a great variety of pleasing scenery. Its islands are thirty in number, few of which, however, measure more than an acre in extent. The largest are Rabbit Island, of more than twelve acres, and Innisfallen, of twenty-one acres. Many of them have a fancied resemblance to particular things, and so are named Lamb, Elephant, Gun, Horse, Crow, Heron, Stag. The chief beauties of this great sheet of water are its generally placid surface, the mountains bordering it on the south and west, and its unlikeness to either of the others, in its low lands, and its estates stretching off to the north and east. It abounds in quiet nooks, bays, and inlets, breaking its margin; and the barren rocks on one side contrast finely with the verdure of the shore on the other. Sir Walter Scott has given a magic charm to Loch Katrine by reciting its legends; but, had he been so disposed, he could have given a like halo to these lakes, for legends of O'Donoghue and of the McCarthys abound, and supply such romantic materials as few countries can boast. As a sample we quote but one:-- Once in seven years, on a fine morning, before the sun's rays have begun to disperse the mist from the bosom of the lake, O'Donoghue comes riding over it on an elegant snowwhite horse, with fairies hovering about him, and strewing his path with flowers. As he approaches his ancient residence, everything resolves itself into its original condition and magnificence; the castle itself, banquet halls, library, his prison, and his pigeon house, are as they were in the olden time. Any one who desires, and is courageous enough to follow him over the lake, may cross even the deepest parts dry-footed, and ride with him into the caves of the adjoining mountains, where his treasures are deposited and concealed; and the daring visitor will receive a liberal gift for his company and venture, but before the sun has arisen, and in the early twilight, O'Donoghue recrosses the water, and vanishes amid the ruins of the castle, to be seen no more till the next seven years have expired. The part of the lake first entered is called Glena Bay, and as the opposite shore, some three miles away, is low, the distant surface of the lake seems to melt into the horizon, producing an effect not made by either of the other lakes. Here on the little bay's shore is the picturesque cottage of Lady Kenmare; and in the woods and highlands, which for a couple and more miles bound the western shore of the lake, are red deer, and the place was once a famous hunting-ground.
