We heard the celebrated organ of St Benedict, which has been praising God in tremendous hallelujahs ever since it was put up, and a hundred years have only matured the richness of its tones. Its voice was gushing out as we entered the church, and filling nave and aisle with a diapason of all that was soft and soothing, as if a choir of Guido's angels had broke out in harmony. A stream of fresh water issues under the old town-wall, and an immense mass of incumbent lava, of at least ninety feet high, impends just above its source, the water struggling through a mass of rock once liquefied by fire, in as limpid a rill as if it came from limestone, and so excellent in quality that no other is used in Catania. Women with buckets were ascending and descending to fetch supplies out of the lava of the dead city below, for the use of the living town above. Moreover, this is the only point in Catania where the accident of a bit of wall arresting for some time the progress of the lava current, has left the level of the old town to be rigidly ascertained. Here, as at _Aci-Reale_, balconies at windows, for the most part supported by brackets, terminating in human heads, give a rich, though rather a heavy, appearance to the street. Much amber is found and worked at Catania. It has been lately discovered in a fossil state, and in contiguity with fossil wood; but we were quite _electrified_ at the price of certain little scent-bottles, and other articles made of this production. You see it in all its possible varieties of colour, opacity, or transparency. The green opalized kind is the most prized, and four pounds was demanded for a pair of pendants of this colour for earrings. Besides the yellow sort, which is common every where, we see the ruby red, which is very rare: some varieties are freckled, and some of the sort which afforded subjects for Martial, and for more than one of the Greek anthologists, with insects in its matrix. _This_ kind, they say, is found exclusively on the coast of Catania. There are such pieces the size of a hand, but it is generally in much smaller bits. Amber lies under, or is formed _upon_ the sand, and abounds most near the _embouchure_ of a small river in this neighbourhood. Many beautiful shells, fossils, and other objects of natural history, appear in the dealers' trays; and polished knife-handles of Sicilian _agate_ may be had at five dollars a dozen. THE LAST OF THE KNIGHTS. DON JOHN AND THE HERETICS OF FLANDERS. It would almost seem as though chivalry were one of the errors of Popery; so completely did the spirit of the ancient orders of knighthood evaporate at the Reformation! The blind enthusiasm of ignorance having engendered superstitions of every kind and colour, the blow struck at the altar of the master idol proved fatal to all.
