Taking into account the vast growth of the metropolis, we are not surprised at so luxurious a means of healthful enjoyment as a racquet court presents being added to the establishments or institutions of this very clubbable age. Hitherto Clubs had been mostly appropriated to the purposes of refection; but why should not the social refinement be extended to the enjoyment of so health-giving sport and manly a pastime as racquet? The experiment was made, and with perfect success, immediately upon the confines of one of the most recent settlements of fashion--Belgravia. It is private property, and bears the name of "Prince's Club Racquet Courts." The Club, established in 1854, is built upon the Pavilion estate, in the rear of the north side of Sloane-street, the principal entrance being from Hans-place. The grounds are of considerable extent, and were originally laid out by Capability Brown. They were almost environed with lofty timber-trees; and the genius of landscape gardening, fostered by wealth, rendered this glade in the Brompton groves of old a sort of rural elysium. The Pavilion estate was once the property of Holland, the well-known architect, who planned Sloane-street and Hans-place, as a building speculation; and, in the grounds nearly between them, built himself what was then considered a handsome villa, the front of which was originally designed by Holland as a model for the Prince of Wales's Pavilion at Brighton; hence the name, the Pavilion estate. In the grounds, among the remains of Brown's ornamental work, was an icehouse, amidst the imitative ruins of a priory. Here, also, were the Ionic columns (isolated) which were formerly in the screen of Carlton House. The Club buildings comprise seven closed courts; a tennis court; gallery and refreshment rooms; baths, and a Turkish bath. Prince's Club is a subscription establishment; and its government is vested in a committee. Gentlemen desirous of becoming members of the Club must be proposed and seconded by two of its members. Two of the rules enact--that members have the privilege of introducing two friends, but that such visitors, if they play, be charged double the rate charged to members; and that no hazard, dice, or game of chance be allowed in this Club. Their Royal Highnesses the Prince of Wales and the Duke of Cambridge are members. AN ANGLING CLUB.
