TRIM, 22 m. N.W. of Dublin, is the assize town.--See picturesque ruins of an ancient Castle, celebrated through all the periods of Irish history; once the property of Mortimer Earl of March: situation romantic; many ruins of Monasteries. The ruins of Bective Abbey stand on a high bank of the Boyne, about 3 m. E. of Trim. Here the tourist may contemplate the domestic range of buildings connected with the Ch.; and, as the walls and division of the apartments are still pretty entire, may form a very good idea of monastic manners. The S. side a range of 12 arches, supported by clustered pillars, opens into a gallery which also runs along the W. From this gallery is an opening into a range of cells, gloomy and inconvenient, and seemingly fitter for the dead than the living. The whole place is indeed sombre in the extreme, with its Gothic doors and windows in several places, and projecting towers and turrets. The outline is picturesque, and deserves a visit. Clonard has some curious monuments in its Abbey ruins. At Newton are the remains of the Ch., belonging to a monastery founded in the 13th century; though much shattered, yet they have once been august, and are now sweetly enveloped in ivy. Tradition attributes (falsely) an ancient tomb to a daughter of King John. On the road from Trim to Mitchelstown see the ruins of a square fortress with circular turrets at the angles, called Scurlack's Town Castle, seated on the borders of the river Boyne, which is here a silent stream full of weeds and rushes. MINERALS. Limestone:--quarries at Ardbraccean, resembling marble. Potter's clay:--has been discovered near Dunshaghlin; is deemed superior to that of Staffordshire. Vitrescent stone:--found in quarries near Slane. BOTANY. _Drosera anglica_, Great Sundew:--on a bog near Isaac-tower. _Nymphæa alba_, White Water Lily:--in the Boyne and other rivers. FERMANAGH. This county will always be an object of interest to the tourist, on account of Lough Erne, besides several smaller pieces of water, on all of which are situated some of the finest mansions and demesnes in the island. Its general surface is mountainous, interspersed with extensive boggy tracts, which rendered it, in early times, almost impregnable, when possessed by the sept of M'Guires. Bounded, S. and W. by Leitrim; N. by Donnegal and Tyrone; E. by Monaghan and Cavan. BELLCOO, 9 m. S.W. of Enniskillen, and on the verge of the county, though a small is yet a neat village, and may form a station for the tourist, being seated on a considerable stream that runs into Lough Mac Nean, and thence to Lough Melve. The well called Davugh Phedric is noted as a cold bath, and nearly equal to Holywell in force. See ruins of Ch. 1 m. From hence also the tourist may visit Florence Court.
