Sixteen years later disorder broke out in north Britain, apparently in the district between the Cheviots and the Derbyshire hills, and was repressed with difficulty after four or five years' fighting.
It is customary to pluck the wool by hand rather than shear it, as this is believed to ensure a finer second crop. Black-faced and Cheviots are also found in some places.
The Roman road of Watling Street crossed the Cheviots at Brownhartlaw (1664 ft.), close to the camp of Ad Fines, by means of which the warlike Brigantes on the south and the Gadeni and Otadeni on the north were held in check, while another Roman road, the Wheel Causeway, passed into Scotland near the headwaters of the North Tyne and Liddel.
The Cheviots do not properly belong to the Uplands, from which they are separated by Liddesdale and other hollows and on which they abut abruptly.
Shorthorns and polled Angus are the commonest breeds of cattle; the sheep are mostly Cheviots and a Cheviot-Leicester cross, but the native sheep are still reared in considerable numbers in Hoy and South Ronaldshay; pigs are also kept on several of the islands, and the horses - as a rule hardy, active and small, though larger than the famous Shetland ponies - are very numerous, but mainly employed in connexion with agricultural work.
The South Tyne and Irthing valleys cut off the Cheviots on the north from the Crossfell section, which is also marked off on the south by the valleys of the Aire and Ribble from the Kinder Scout or Peak section.
