The Privy Garden, on the west side of the mansion, is enclosed within a high and closely-cut hedge, with a close walk or avenue all around it. In each of the four angles stood a mulberry tree, said to have been planted by King James I., and in the centre is a pond surrounded by rock-work. The three pairs of splendid entrance-gates, of French metal work, and of the most elaborate and artistic character, were put up by the late Marquis of Salisbury in 1846, when Hatfield House was honoured by the presence of her Majesty and the Prince Consort. The town of Hatfield presents few objects of antiquity; it stands on the side of a hill, on the height of which are the gates of the mansion. Close at hand is the parish church, a structure with little pretence to architectural beauty. We may not omit to mention that at the termination of the grounds runs the clear and beautiful river Lee—here of considerable depth. There is no bridge to cross to the other side, where are the kitchen gardens of the house, but a ferry-boat is always at hand. On a steep above the river is the yew-tree walk—a series of pathways bordered by the venerable trees, dwarfed generally, but producing a most agreeable effect. In all respects, therefore, Hatfield House is largely gifted by Nature as well as Art. CASSIOBURY. CASSIOBURY, or Cashiobury, as it is sometimes spelt, lies about a mile distant from Watford, in Hertfordshire. It is, therefore, within easy distance—sixteen miles—from London, and may be considered as one of the breathing places of denizens of the Metropolis. The name of Cassiobury is said, and with reason to be derived from the Casii, a tribe of the Britons who occupied the district, and whose stronghold, Verulamium, lies only a few miles away. The Casii were, at the time of the landing of Julius Cæsar, commanded by Cassivelanus, under whom they fought many battles with the invaders. The hundred is still called the hundred of Cassio, and the affix of _bury_ evidently signifies an assemblage of dwellings surrounded by walls, or a burgh or borough. “Being as its name implies, the only _bury_ within the manor of Cassio during the Saxon era, it might have been either the seat of justice for the hundred (for the name _bury_ will admit of this construction), or an occasional retreat of some of the British princes residing at Verulamium, of whom Cassivelanus was one,” and by some writers it is stated to have been “the actual seat or home of Cassivelanus.”
