_Tring Park_ (property of Hon. N. C. Rothschild) is surrounded by perhaps the most exquisite woods--largely of beech--in the whole county. Much altered in modern times, it is said to have been designed by Wren, and to have been visited by Charles II. The park is well kept, and contains many living curiosities placed here by Lord Rothschild, a lover of natural history. The _Museum_, at the top of Akeman Street, containing a fine zoological collection, is the outcome of his lordship's energy and benevolence. The _Museum House_, to which it is attached, is a prettily designed structure of red brick, with gables. _Tring, Little_, is a hamlet 11/4 mile N.W. from the town, and Tring Grove, a hamlet 11/4 mile N.E. The former is near the large reservoirs, upon which several of the rare birds mentioned in the Introduction (Section IV.) were observed. _Trowley Bottom_ (3 miles N.W. from Redbourn Station, M.R.) is a hamlet a little S. from Flamstead, in one of the most thoroughly rural districts in the county. The Roman _Watling Street_ (St. Albans-Dunstable road) is 1 mile N.E. _Turnford_ (11/4 mile S.W. from Broxbourne Station, G.E.R.) is a hamlet in Cheshunt parish, on the New River. _Broxbourne Bury Park_ is 1 mile N. _Two Waters_ owes its name to its position at the junction of two small rivers--the Gade and the Bulbourne. It is in Hemel Hempstead parish, and about 1 mile E. from Boxmoor Station. _Tyttenhanger._ (See Tittenhanger.) _Upwick Green_ (4 miles N.W. from Bishop's Stortford) is a hamlet on the Essex border. _Hadham Hall_ (see Little Hadham) is 1 mile S. VERULAM. Of the old Roman _municipium_ (_Verulamium_) there now remains above ground little more than some large fragments of crumbling wall in the valley of the Ver, immediately S.W. from St. Albans. Passing under the old Gatehouse and crossing the bridge at the Silk Mill the visitor, instead of turning right and following the course of the Ver, should keep straight on and pass the small gate into Verulam Woods. On his right as he follows the broad footpath will be the outer E. wall of the Roman city; on his left what appears a long gorge, overgrown by bushes and trees of many species, was once the _fosse_. Note the great thickness and solidity of the walls, and the tile-like bricks, similar to those in the Abbey tower, mingled with flints. Presently both wall and fosse turn sharply W. and may be followed in that direction for a considerable distance. The walls may also be traced at other spots farther W., particularly a large mass known as Gorhambury Block, believed to mark the boundary of the _municipium_ in that direction.
