Yore we find it in Middleham moor eight hundred and fifty feet, in 
Pen hill twelve hundred feet, in Bear’s Head nineteen hundred feet; 
on the north side of the Yore it is found at Leyburn seven hundred 
feet, above Bolton castle thirteen hundred feet, between Askrigg and 
Muker seventeen hundred feet, on the south side of Lovely Seat seven- 
teen hundred feet, in Cotter fell (not the hill so named by Mr. Nixon) 
sixteen to seventeen hundred feet. 
In Swaledale at Richmond the main limestone is three hundred feet 
above the sea, hence it rises westward south of the Swale to Downholme 
eight hundred feet, Sattron Hangers sixteen hundred feet, north side of 
Lovely Seat fifteen hundred and fifty feet; and north of the Swale, to 
Marsk, nine hundred and fifty feet, Fremington edge one thousand feet, 
Calvey sixteen hundred feet, Arkendale head thirteen hundred feet. At 
Swaledale head the main limestone is elevated seventeen hundred feet. 
In Teesdale at Rokeby the main limestone is four hundred feet above 
the sea, hence it rises westward along the Greta to Bowes nine hundred 
and forty-two feet, and Stainmoor fourteen hundred feet ; under grits 
and shales north-westward to Middleton one thousand feet, and Mickle 
fell two thousand five hundred and thirty-three feet. 
Axes of declination . — Besides this general slope from the Penine 
fault, we find local slopes related to certain valleys and other marking 
lines of physical geography. There is a decided and constant slope 
from the edge of Wharfedale to Wensleydale, which is evident in all 
the ridges between the southern branches of Wensleydale. The main 
limestone at Coverdale head is elevated sixteen hundred feet above the 
sea, and it sinks north-east to East Witton twelve hundred feet in 
twelve miles : under Buckden pike it is eighteen hundred and fifty feet ; 
at the head of Walden dale sixteen hundred feet, but sinks north-east 
to twelve hundred in Pen hill ; at the head of Bishopdale it is nineteen 
hundred feet ; hence the dip to Pen hill north-east is seven hundred 
feet in seven miles, but in the direction north-west, the rock ranoes 
level, for it is equally high in Bear’s head. This result of a maximum
