His ideas indeed went beyond this: far larger schemes of extension were conceived by him in connection with the designs for the Government Offices. But [Illustration: THE PRIVY COUNCIL OFFICE, BOARD OF TRADE, AND TREASURY, WHITEHALL. AFTER THE ALTERATIONS BY SIR CHARLES BARRY.] [Illustration: TRENTHAM HALL, STAFFORDSHIRE.

TRENTHAM HALL.--The next group of alterations to be noticed brings into prominence a kind of work, in which he took the greatest pleasure, and achieved very brilliant results. This was the architectural laying out and ornamentation of gardens. Early in his career he had made some essay in this direction at Mr. Attree’s house in Brighton Park. Up to the last he retained almost a passion for it. His idea was that the definite artificial lines of a building should not be contrasted, but harmonized, with the free and careless grace of natural beauty. This could only be effected by a scheme of architectural gardens, graduated, as it were, from regular formality in the immediate neighbourhood of the building itself, through shrubberies and plantations, less and less artificial, till they seemed to melt away in the unstudied simplicity of the park or wood without. In this the architect and landscape gardener must work side by side. These views he had the opportunity of exemplifying on a grand scale in the works carried on for many years at Trentham Hall, the residence of the Duke of Sutherland. To the old building containing the state reception rooms, he simply gave a better cornice and improved its details, adding moreover a grand entrance hall, which served also as a billiard saloon, and communicated with the state rooms by a fine semicircular corridor. He succeeded also in grouping together very effectively the straggling offices of the great house. Though he could not effect all that he wished, he was able thus to give some grandeur and unity to the large mass of building. The design of the private wing has been already mentioned.
