But, amidst all these wonders of 1851, are there no plain, simple, practical plans sent in? There are a good many. Some of these are certainly not very attractive, presenting, as they do, the appearance of a superior kind of barracks, hospitals, alms-houses, nursery-grounds; and one of these plans is laid out entirely like a series of cucumber-frames, with shifting lights at top. There are, however, several of these sober designs which possess great practical merit, and have preserved a due consideration of the terms on which the competition was proposed. Of these, the Commissioners and Committees have availed themselves in all respects suited to their own views and wishes; and out of all these, combined with their own especial fancies, they seem likely to produce an interminable range of cast-iron cow-sheds, having (as a specimen of the present high state of constructive genius) an enormous slop-basin, of iron frame-work, inverted in the centre, as an attraction for the admiring eyes of all the nations. But other problems have to be solved. The classification and arrangement of the raw materials, the manufactured articles, the machinery, and the works of plastic art, is a question of very great importance. It not only involves the things themselves, but their respective countries. Should the productions of each country be kept separate? This appears the natural arrangement, or how should any one make a study of the powers of any special country. Prince Albert, it seems, wishes otherwise. He thinks that a fusion of the productions of all nations will be more in accordance with the broad general principle of the Exhibition—more tending to amalgamate and fraternise one country with another. This feeling is excellent; but we fear it would cause an utter confusion, and amidst the heterogeneous masses, nobody would be able to make a study of the productions of any particular nation. An eminent civil engineer suggests that the productions of the respective countries should be ranged together from side to side of the entire width of the edifice—thus you can at once see the works of industry of England, France, Germany, America, Switzerland, &c., &c., by walking up and down from one side to the other; and you can obtain a collective view of the works of all these countries by walking longitudinally, or from end to end of the building. To some such classification and arrangement as this, we think, the Committee will be compelled to have recourse at last.
