[A] AIRE, (The) rises from a small lake on the moors of Yorkshire, north-east from Settle, descending through Aire-dale and Craven in its course to the south-east, which it pursues as far as Leeds, where, turning eastward, and meeting the Calder, it passes under Ferrybridge, flowing through the flattest portion of Yorkshire; and receiving the Don, a little north of Snaith, it unites with the Ouse above Booth Ferry, near Howden. This river is of greater extent than the Calder, and much its superior in navigation, being also joined by numerous canals from the west. Its origin is almost mountainous, in the midst of the wildest moors; and Aire-dale retains much of the same characteristic features of that line of country. The district of Craven is singularly romantic, being a rich vale, bounded by high hills, with the town of Skipton in its centre; below which it forms a beautiful valley to Keighley, full of trade and population; the Aire passes the picturesque ruin of Kirkstall Abbey, in its way to Leeds, the manufactories and villas of which flourishing place, and its vicinity, encompass its banks; after which it divides one of the richest plains in the kingdom to Ferrybridge, not far from the eminence where the town of Pontefract appears a conspicuous object, with its ruined castle and ancient church. Afterwards the Aire can boast little of beauty, as it advances through a level district to join the Ouse.

The great and attractive objects which grace its borders are placed in the far-extended territory of the Duke of Northumberland, at the entrance to which the lofty building, called Brisley Tower, thickly environed by plantations, overlooks all the wild country of Northumberland, including the bold range of Cheviot-hills on the north-west, close to the Scottish border. The Alne then enters a charming valley, beneath the ivied walls of Hulne Abbey, winding delightfully between lawns, woods, and groupes of trees and cottages, admirably disposed. From these monastic and rustic recesses, the river emerges into a spacious park, widened considerably by art, and gliding through the arches of a fine Castellan bridge, is proudly overlooked by the numerous towers, and lofty citadel of Alnwick Castle, the superb seat of the Northumberland family.
