Bur-Hill (see page 162), the Excavation is immensely deep 

 and wide into the upper part of the Coal Series, as I judge; 

 tfom thence for about 2^ m. the Excavation is in the 

 Lime-stone Shale, the River appmachnig a Hill of Luiie- 

 stone Shale at Bur- Hill, \V" of Little Eaton, and others, 

 in a range called Duiiield Bank, having the isl Grit 

 Hock upon them; the Ouartz Gravel floor to the Val- 

 ley, t-xtends up as far as this Excavation in Shale near 

 Makeney, but no furiher. Hctween Millord and Make- 

 nev, the River is deeply and suddenly excavated in the 1st 

 Grit Rock, which is there crossing to the west side of it, and 

 the River then for about 2 m. has its course in the 'st Coal- 

 shale, and the Artriilaceous Grit beds in it, crossing the 

 line of Section in Mr. VVliilehurst's Plate \..*, SudEdil. of 

 his " Inquiry," ntar the SVV corner of Bclper Town ; the 

 2nd Grit Rock upon it, being cut entirely through at the 

 N end of the Town, and a large Hummock of it left lo th.e 

 \V, which the Wirkjworth Road crosses. For about the 

 next n)ile and quarter, ihe Excavation is aiiain made very 

 deep in the I si Grit Rock, up to Toad moor Bridge at 

 Blundon-Ford, near the niouili of the Amber, and thence 

 the same is cui m the Limestone Siiale, to Cromford Bridge, 

 having entered ihe western edge of the i;reat Deiiudaiioii 

 around Crich (see ])age 171)» l-be l!»t Grit forms prodigious 

 Ciifls in the Heights on each side the River, uj) to Cod- 

 dinglon, near the inoulh of VVakebridge Sough (now driving 

 to the Crich Cliff Mines), on the we»i side, ihtsc Ciifls of 

 1st Gnt turn o[f, on the north side of Crondord Moor, to 

 Barchill Edge Hill, and on the east side ihey terminale> 

 abruptly at a Fault. 



At Cromford Bridge the Excavation enters on the 1st 

 Lime Rock, and having cut through this, at the Paper MiH 

 in Matlock- Bath Dale (see page CB), it crosses ihe 1st 

 Toadstone (which is here crossing the River to the east 

 bank, see page 281) ; from hence tor about -«■ of a mile, the 

 bed of the River is on the 2nd Lime Ruck : the 1st Toad- 

 stone then awain crosses to the west side, and immediately 

 the 1st Lime Rock does ihe same: and then the River runs 

 for a short distance upon an Excavation in a sunk piece or 

 Trough of Shale, and quickly after, by a rapid rise of the 

 measures towards the north, the I si Lime, and ihcn the 1st 

 Toad-ilone, again cross the River, and immediatelv the 2iid 

 Lime Rock does the same; and the River then for about 

 ihe ^ part of a mile, at the foot of the High Tor, luns upon
