These two great plans are now shortly to be carried out. There remain others, the execution of which must surely be a question only of time. For the work, which has been commenced, of remodelling our public offices, can hardly stop short. The Board of Trade, the Foreign Office, and the India Board cannot be allowed to exist as isolated specimens of a better style, contrasting with the meagre ineffectiveness of our older buildings. HORSE GUARDS.--In 1846 Sir Charles received instructions to prepare plans for the enlargement of the Horse Guards. To confine himself to the limits of instructions was hardly possible for him. He had long sighed over the insignificance of the building, and the want of all effect about the Parade. Insignificant in itself, it seemed still more unworthy of its position, as forming a part of the “Via Regia,” the Sovereign’s approach to Parliament. Ideas floated before his mind of a second “Place du Carrousel.” The opportunity was too tempting to be resisted. Accordingly he provided indeed for additional accommodation by an additional story; but, having done this, he made a further ideal design, raising the centre into a tower-like mass, introducing other alterations on all sides, and transforming the building into a grand composition. The Parade by ornamental enclosures was brought into architectural connection with the design; the road from the Mall led by a gentle sweep to a grand entrance opposite the building, and at this entrance the “Marble Arch,” then just removed from its position at Buckingham Palace, and cast upon the world for a habitation, was to be placed. The Wellington Statue, then also in search of a resting-place, was to form a central feature of the Parade, over which its illustrious original still presided. The other buildings near, the Admiralty, Treasury, &c., were to be brought into connection with its design; and a grand Place d’Armes was to be formed, second to none in Europe. The idea was long a favourite one; he returned to it again in his “Metropolitan Improvements,” and his work at the Board of Trade shows what might have been effected by his talent for conversion. Nothing indeed was done; there was some doubt whether the foundation of the old building would bear the additions contemplated. The design itself, intrusted to the Government, was lost, and no trace of it can now be found. But, sooner or later, the work must be carried out, and, when it is carried out, it will in all probability follow the main lines of the arrangement which has thus been indicated. BRITISH MUSEUM.--Another design of his on a still larger scale had relation to an institution, in which he always felt the most lively interest.
