92 RIVERS. 



monument to his fortunate enemy. The general current of 

 opinion places Derventio at Stamford Brig. But we have found 

 no camp there, nor any abundance of Roman reliquiae ; nor does 

 it seem likely that such a place, only seven miles from York, 

 should give a permanent name to a detachment of troops, as

 Brig, Roman urns and coins have been found ; and at Dunning- 

 ton a votive altar. 



The river now flows by Kexby, Elvington, and Wheldrake, 

 and receives a small branch from Pocklington at Cottingwith. 

 Ellerton Priory (of the 13th century) a little further south, and 

 now a parish church, stands on the east bank. Wresill Castle, 

 one of the most interesting of the many strongholds of the 

 Percys, is still farther down the river on the same side, and close 

 to the floodway of the Derwent, the navigation of which it must 

 have commanded. 



Most readers would have shared the delight which Leland 

 expresses in the following passage on Wresill : " One thing I 

 liked exceedingly in one of the towers, that was a study called 

 Paradise, where was a closet in the middle of eight squares, lati- 

 fied about, and at the top of every square was a desk ledged to 

 set books or covers within them, and these seemed as joined hard 

 to the top of the closet, and yet by pulling one or all would 

 come down breast-high in rabettes, and serve for desks to lay 

 books on." 



THE AIRE*. 



Airedale has an origin quite unlike that of any other great 

 Yorkshire dale, for its river springs at once, a full stream, from 

 under a huge cliff of limestone called Malham Cove, 285 feet in 

 height. The water is supplied by subterraneous channels in the 

 limestone ; some no doubt comes by this means from Malham 

 Water a beautiful lake, strangely placed on the high ground 



* ' Air ' is a British word for ' bright.'
