On the 20th of May, 1867, the “ first stone “ of the Royal Albert Hall of Arts and Sciences, of which we present an illustration, was laid with all due solemnity and ceremonial by her Majesty the Queen ; and now, at the end of little over two years, the vast building is nearly completed, and is only waiting to be covered in by its vast roof to allow of all its interior fittings and arrangements being set up. In form it bears some resemblance to a Roman amphitheater, although its materialnamely, red brick faced with terra cottagoes far to destroy the illusion. Still, it is only justice ta the architect to admit that the general effect of his work is both pleasing and imposing. Its magnitude will be best indicated by giving the exact dimensions in figures. The long diameter of the outer wall is 272 feet, the short. est 238 feet, the le^th between the porches 388 feet, the breadth of the ellipse 332 feet, and the hight 135 feet. The interior is arranged to accommodate comfortably an audience of 8,000, to be divided as follows : In the arena, situate in the center of the building, 1,000 can be accommodated for the musical performances, and when the space is not occupied, by a flower show or an industrial exhibition. The amphitheater, which rises gradually all round the arena under the boxes, will hold 1,400, the boxes 1,100, the balcony 2,500, and the gallery 2,000. Theboxes have already subscribed for it at $5,000 each, and a great number of the single seats at $500, but it is calculated that between 5,000 and 6,000 sittings will still be available as a source of revenue for carrying out the objects of the hall. The building is now complete both as to its outer and inner walls, between which, it should be mentioned, run vast and airy corridors for promenade as well as ingress and egress. The next great work will be the fixing in its place of the immense roof of iron and glass, for the purposes of which the whole interior of the building is at present filled with a perfect forest of scaffolding. This roof will be the greatest span of any work of the kind yet erected. Its long diaJIleter will be 219 feet 4 inches; short, 185 feet 4 inchesan immense weight, it will be said, to be self-sustained. As, however, the calculations, have all been made for lead, where glass is only to be used, there is every reason to calculate on its strength and durability. The only remarkable feature remaining to be noticed is the great organ in course of erection by Mr. Willis, the builder of the organ in St. George's Hall, Liverpool. Its dimensions will be 75 feet wide at the base, 44 feet in depth, 60 feet in width, and hight 100 feet. There are to be 112 steps, and the bellows is to be kept going by two steam engines of from 6 to 8-horse power each. The largest organ at present known is the great organ at the Crystal Palace, but in the Kensington instrument the smallest pipe in the front will be longer than the longest pipe in the interior of its Sydenham predecessor. It is expected that the whole workbuilding, organ, and approacheswill be finished so as to open simultaneously with the proj ected International Industrial Exhibition in 1871, and that one of the earliest uses to which it will be put will be the ceremonial distribution of the prizes which will arise out of these exhibitions. The entire programme of its contemplated uses comprehends congresses, national and international, of science and art, performances of music on the grandest scale, distributions of prizes by public bodies, art and science conversazioni, agricultural, horticultural, and industrial exhibitions, and the occasional display of pictures and sculpture. For this latter purpose there will be an immense top-lighted gallery running all rouud the hall. It is satisfactory to be able to add that, in a building which is intended to accommodate assemblages of | may be 8,000 persons due care has been taken to provide ample facilities for entrance and exit.London Artizare. other various forms of fire-goods are usually applied, have, according to the Mechanics' Magazine, been patented in England. Instead of using fire-bricks, lumps, stones, tiles, or other forms of materials or compounds, in construction, burnt or unburnt, powdered ganister stone, quartz, sand, mica, sandstone, or other silicious material, plumbago, lime, baryta, steatite, and magnesia, are used, alone or separately, or in varied proportions with fire-clays, or with each other, or with silicious or other solutions, mixed or not with hair, fiber,saw- dust, shavings, or pulverized coke, or with other analogous materials. In applying the materials in a plastic state, wire may be used ag a supporter, or a skeleton or light framework not he necessary to keep large stocks of varied shapes of bricks, the loss of material and labor in making joints will be saved, while, in case of actual wear, additions can be supplied internally or externally to the structure so that it may be easily and speedily repaired.
