lofty moors of Mossdale and Abbotside, some of which, are diversified by 
waterfalls of considerable height. During the earlier part of its course it 
runs in an eastern direction, almost parallel with the Swale, at a distance 
from it varying from five to seven miles. Opposite the town of Askrigg it 
receives a considerable stream from Seamer water, which rises amongst 
the summits of Stake Fell and Yokenthwaite moor. The district which the 
Ure drains on the north is necessarily very limited, and seldom exceeds 
three miles in breadth. It includes the town of Leyburn, and the ruins of 
the castle of Bolton. Below Askrigg are three interesting waterfalls, the 
largest of which, Millgill Force, is 69 feet in height. There is another, 
rather lower down, at Aysgarth, after which the river is considerably 
augmented by the united streams which flow down Bishopdale and 
Waldendale. Passing beneath the peak of Penhill, (1817 feet) at Middle- 
ham, it is joined by the Cover, which rises near to Little Whernside, not 
far from the head of Nidderdale. At Witton and Jerveaux Abbey it enters 
the central vale, and flows in a south eastern direction for the remainder 
of its course. From Masham to its junction with the Swale, it forms the 
boundary between the north and west ridings. 
Surface. — As mentioned under the last district, a portion of the water- 
shed between the Swale and the Yore attains the arctic region. At the 
point of juncture between the north and west ridings, the peaks of Wild 
Boar Fell, Swarth Fell, Bow Fell, and Sayls, attain or exceed 2200 feet. 
Between Widdale and Cotterdale, and towards the head of the former 
dale, and along the summit of drainage between Wensleydale and Kettle- 
welldale, are several fells of considerable altitude, with lateral ridges 
between Bishopdale, Coverdale, and Nidderdale. The remainder of the 
western portion of the district, including the valley of the Ure above 
Hawes, and the moorlands to Leyburn and Witton, are comprised in the 
middle zone. The lower zone includes a narrow strip of surface which 
stretches along the north side of the river to its junction with the Swale, 
and the less elevated portions of the various dales. 
Structure. — As before mentioned, the watershed between the Swale 
and the Ure consists of mill-stone grit strata, which also descend to the 
river at Masham, and form the summit of drainage between Bishopdale 
and Coverdale. The surface of the remainder of the western portion of 
the district consists of a series of limestones of earlier date, which have
