This passage, which Denmark had so long considered as the key of the Baltic, is, in its narrowest part, about three miles wide; and here the city of Elsinore is situated; except Copenhagen, the most flourishing of the Danish towns. Every vessel which passes lowers her top-gallant sails and pays toll at Elsinore; a toll which is believed to have had its origin in the consent of the traders to that sea, Denmark taking upon itself the charge of constructing lighthouses, and erecting signals, to mark the shoals and rocks from the Cattegat to the Baltic; and they, on their part, agreeing that all ships should pass this way in order that all might pay their shares: none from that time using the passage of the Belt, because it was not fitting that they who enjoyed the benefit of the beacons in dark and stormy weather, should evade contributing to them in fair seasons and summer nights. Of late years about ten thousand vessels had annually paid this contribution in time of peace. Adjoining Elsinore, and at the edge of the peninsular promontory, upon the nearest point of land to the Swedish coast, stands Cronenburgh Castle, built after Tycho Brahe's design; a magnificent pile--at once a palace, and fortress, and state-prison, with its spires, and towers, and battlements, and batteries. On the left of the strait is the old Swedish city of Helsinburg, at the foot, and on the side of a hill. To the north of Helsinburg the shores are steep and rocky; they lower to the south;and the distant spires of Lanscrona, Lund, and Malmoe are seen in the flat country. The Danish shores consist partly of ridges of sand; but more frequently they are diversified with cornfields, meadows, slopes, and are covered with rich wood, and villages, and villas, and summer palaces belonging to the king and the nobility, and denoting the vicinity of a great capital. The isles of Huen, Statholm, and Amak, appear in the widening channel; and at the distance of twenty miles from Elsinore stands Copenhagen in full view; the best city of the north, and one of the finest capitals of Europe, visible, with its stately spires, far off. Amid these magnificent objects there are some which possess a peculiar interest for the recollections which they call forth. The isle of Huen, a lovely domain, about six miles in circumference, had been the munificent gift of Frederick the Second to Tycho Brahe. It has higher shores than the near coast of Zealand, or than the Swedish coast in that part. Here most of his discoveries were made; and here the ruins are to be seen of his observatory, and of the mansion where he was visited by princes; and where, with a princely spirit, he received and entertained all comers from all parts, and promoted science by his liberality as well as by his labours. Elsinore is a name familiar to English ears, being inseparably associated with HAMLET, and one of the noblest works of human genius. Cronenburgh had been the scene of deeper tragedy: here Queen Matilda was confined, the victim of a foul and murderous court intrigue. Here, amid heart-breaking griefs, she found consolation in nursing her infant. Here she took her everlasting leave of that infant, when, by the interference of England, her own deliverance was obtained;and as the ship bore her away from a country where the venial indiscretions of youth and unsuspicious gaiety had been so cruelly punished, upon these towers she fixed her eyes, and stood upon the deck, obstinately gazing toward them till the last speck had disappeared.
