In all probability Leland's form represents '_Cotter End_,' by which name, though not given in most of the maps, part of the hill is still known. =Cove=: often means 'cave' in Yorkshire and Scotland, but as a rule it is a large recess in a hill-side. =Craven=--_Camden_ remarks that the country lying about the head of the river Aire is called in our tongue _Craven_, 'perchance of the British word _Crage_, that is a _Stone_. For the whole tract there is rough all over, and unpleasant to see to; which [with?] craggie stones, hanging rockes, and rugged waies.' Modern climbers, however, find it hardly rocky enough for them, at least above ground, and have been driven to invent a new variety of climbing--the subterranean. Exploration of the numerous _potholes_ which honeycomb the limestone hills has of late years become a favourite pastime, and, in truth, it combines science with adventure to a marked degree. Any one who tarries for any length of time among these Yorkshire dales should read Mr. H. Speight's handsome volume, which gives a very complete account of the beauties and the curiosities which they have to show. =Cross Fell=, in Cumberland, long enjoyed the reputation being one of the highest mountains in England, and as late as 1770 its height was calculated at 3,390 ft., which is some 500 ft. more than it is entitled to. It was earlier than most English mountains in becoming the object of scientific curiosity, and an account of it will be found in the _Gentleman's Magazine_ for 1747. It is chiefly celebrated for the Helm Wind originating from it. =Cumberland= is the premier climbing county. The best centres are _Wastdale Head_, _Rosthwaite_ or _Seatoller_, _Buttermere_, _Keswick_ and _Eskdale_. The cream of the climbing is on those fells which are composed of rocks belonging to what is called 'the Borrowdale Series,' such as _Scafell Pillar_, _Gable_, _Bowfell_, and as a rule the finest climbs are found on the sides which face the north and east. _Cross Fell_ does not belong to the same mountain-system as those just mentioned, and offers little climbing. The best cliffs on the coast are about _St. Bees_ Head.
