your any thing but love to you: solicitous as they have ever been for welfare, always consider the same tender solicitude as exerting itself, even in cases most opposite to your desires; and let the remembrance of what they have done and suffered for you, ever preserve you from acts of disobedience, and from paining those good hearts which have already felt so much for you, their children. The Emperor of China, on certain days of the year, pays a visit to his mother, who is seated on a throne to receive him; and four times on his feet, and as often on his knees, he makes her a profound obeisance, bowing his head even to the ground. Sir Thomas More seems to have emulated this beautiful example; for, being Lord Chancellor of England at the same time that his father was a Judge of the King's Bench, he would always, on his entering Westminster Hall, go first to the King's Bench, and ask his father's blessing before he went to sit in the Court of Chancery, as if to secure success in the great decisions of his high and important office. Dr. Dodd. QUEEN MARY'S BOWER, CHATSWORTH. 66 HEN the widowed Mary, Queen of Scots, left France, where she had dwelt since her fifth year—where she had shared in the education of the French King's own daughters, in one of the first convents of the kingdom, and been Hhe idol of the French Court and people, it is said that, as the coast of the happy land faded from her view, she continued to exclaim, Farewell, France! farewell, dear France—I shall never see thee more!" And her first view of Scotland only increased the poignancy of these touching regrets. So little pains had been taken to "cover over the nakedness and poverty of the land," that tears sprang into her eyes, when, fresh from the elegant and luxurious Court of Paris, she saw the wretched ponies, with bare, wooden saddles, or dirty and ragged trappings, which had been provided to carry her and her ladies from the waterside to Holyrood." And then the palace itself; how different from the palaces in which she had lived in France! Dismal and small, it consisted only of what is now the north wing. The state-room and the bedchamber which were used by her yet remain, with the old furniture, and much of the needle-work there is said to have been the work of her hands. During her long and melancholy imprisonment in England, the art of needle-work and reading were almost her only mode of relieving the dreary hours. From the moment Mary of Scotland took the fatal resolution of throwing herself upon the supposed kindness and generosity of Elizabeth, her fate was sealed, and it was that of captivity, only to be ended by death. She was immediately cut off from all communication with her subjects, except such as it was deemed proper to allow; and was moved about from place to place, the better to ensure her safety. The hapless victim again and again implored Elizabeth to deal generously and justly with her. "I came," said she, in one of her letters, "of mine own accord; let me depart again with yours: and if God permit my cause to succeed, I shall be bound to you for it." But her rival was unrelenting, and, in fact, increased the rigours of her confinement. Whilst a prisoner at Chatsworth, she had been permitted the indulgence of air and exercise; and the bower of Queen Mary is still shown in the noble grounds of that place, as a favourite resort of the unfortunate captive. But even this absolutely necessary indulgence was afterwards denied; she was wholly confined to the Castle of Fotheringay, and a standing order was issued that "she should be shot if she attempted to escape, or if others attempted to rescue her." Burns, in his "Lament of Mary, Queen of Scots," touchingly expresses the weary feelings that must have existed in the breast of the Royal captive:— "Oh, soon to me may summer suns Nae mair light up the morn! And in the narrow house of death, And the next flowers that deck the spring, TUBULAR RAILWAY BRIDGES. In the year 1850, a vast line of railway was completed from Chester to Holyhead, for the conveyance of the Royal mails, of goods and passengers, and of her Majesty's troops and artillery, between London and Dublin— Holyhead being the most desirable point at which to effect this communication with Ireland. Upon this railway are two stupendous bridges, which are the most perfect examples of engineering skill ever executed in England, or in any other country. The first of these bridges carries the railway across the river Conway, close to the ancient castle built by Edward I. in order to bridle his new subjects, the Welsh. The Conway bridge consists of a tube, or long, huge chest, the ends of which rest upon stone piers, built to correspond with the architecture of the old castle. The tube is made of wrought-iron plates, varying in thickness from a quarter of an inch to one inch, riveted together, and strengthened by irons in the form of the letter T; and, to give additional strength to the whole, a series of cells is formed at the bottom and top of the tube, between an inner ceiling and floor and the exterior plates; the iron plates which form the cells being riveted and held in their places by angle irons. The space between the sides of the tube is 14 feet; and the height of the whole, inclusive of the cells, is 22 feet 3 inches at the ends, and 25 feet 6 inches at the centre. The total length of the tube is 412 feet. One end of the tube is fixed to the masonry of the pier; but the other is so arranged as to allow for the expansion of the metal by changes of the temperature of the atmosphere, and it, therefore, rests upon eleven rollers of iron, running upon a bed-plate; and, that the whole weight of the tube may not be carried by these rollers, six girders are carried over the tube, and riveted to the upper parts of its sides, which rest upon twelve balls of gun-metal running in grooves, which are fixed to iron beams let into the masonry. The second of these vast railway bridges crosses the Menai Straits, which separate Caernarvon from the island of Anglesey. It is constructed a good hundred feet above high-water level, to enable large vessels to sail beneath it; and in building it, neither scaffolding nor centering was used. The abutments on either side of the Straits are huge piles of masonry. That on the Anglesey side is 143 feet high, and 173 feet long. The wing walls of both terminate in splendid pedestals, and on each are two colossal lions, of Egyptian design; each being 25 feet long, 12 feet high though crouched, 9 feet abaft the body, and each paw 2 feet 4 inches. Each weighs 30 tons. The towers for supporting the tube are of a like magnitude with the entire work. The great Britannia Tower, in the centre of the Straits, is 62 feet by 52 feet at its base; its total height from the bottom, 230 feet; it contains 148,625 cubic feet of limestone, and 144,625 of sandstone; it weighs 20,000 tons; and there are 387 tons of cast iron built into it in the shape of beams and girders. It sustains the four ends of the four long iron tubes which span the Straits from shore to shore. The total quantity of stone contained in the bridge is 1,500,000 cubic feet. The side towers stand at a clear distance of 460 feet from the great central tower; and again, the abutments stand at a distance from the side towers of 230 feet, giving the entire bridge a total length of 1849 feet, correspond ing with the date of the year of its construction. The side or land towers are each 62 feet by 52 feet at the base, and 190 feet high; they contain 210 tons of cast iron. The length of the great tube is exactly 4/0 feet, being 12 feet longer than the clear space between the towers, and the greatest span ever yet attempted. The greatest height of the tube is in the centre—30 feet, and diminishing towards the end to 22 feet. Each tube consists of sides, top and bottom, all formed of long, narrow wrought-iron plates, varying in length from 12 feet downward. These plates are of the same manufacture as those for making boilers, varying in thickness from three-eighths to three-fourths of an inch. Some of them weigh nearly 7 cwt., and are amongst the largest it is possible to roll with any existing machinery. The connexion between top, bottom, and sides is made much more substantial by triangular pieces of thick plate, riveted in across the corners, to enable the tube to resist the cross or twisting strain to which it will be exposed from the heavy and long-continued gales of wind that, sweeping up the Channel, will assail it in its lofty and unprotected position. The rivets, of which there are 2,000,000—each tube containing 327,000—are more than an inch in diameter. They are placed in rows, and were put in the holes red hot, and beaten with heavy hammers. In cooling, they contracted strongly, and drew the plates together so powerfully that it required a force of from 4 to 6 tons to each rivet, to cause the plates to slide over each other. The weight of wrought iron in the great tube is 1600 tons. Each of these vast bridge tubes was constructed on the shore, then floated to the base of the piers, or bridge towers, and raised to its proper elevation by hydraulic machinery, the largest in the world, and the most powerful ever constructed. For the Britannia Bridge, this consisted of two vast presses, one of which has power equal to that of 30,000 men, and it lifted the largest tube six feet in half an hour. The Britannia tubes being in two lines, are passages for the up and down trains across the Straits. Each of the tubes has been compared to the Burlington Arcade, in Piccadilly; and the labour of placing this tube upon the piers has been assimilated to that of raising the Arcade upon the summit of the spire of St. James's Church, if surrounded with water. Each line of tube is 1513 feet in length; far surpassing in size any piece of wrought-iron work ever before put together; and its weight is 5000 tons, being nearly equal to that of two 120-gun ships, having on board, ready for sea, guns, provisions, and crew. The plate-iron covering of the tubes is not thicker than the hide of an elephant, and scarcely thicker than the bark of an oak-tree; whilst one of the large tubes, if placed on its end in St. Paul's churchyard, would reach 107 feet higher than the cross of the cathedral.
