218 Mr, Bubble's Synopsis of the Newcastle Coal Field. 



NOTES REFERRING TO THE SYNOPTICAL TABLE AND MAP. 



The Newcastle Coal Field is divided into two large districts, called 

 the Tyne, and Wear Water ; the former comprising all the collieries 

 which ship their coals on the Tyne, the latter comprising all those col- 

 lieries which ship their coals on the Wear. To facilitate the descrip- 

 tion of this Coal Field, I have sub-divided the Tyne and Wear districts, 

 each into two parts, as follows, viz. : — 



THE TYNE. 



The sub-division east of the meridian of Newcastle, coloured pink on 

 the Map, Plate XX., extends from the river Blyth to the south side of the 

 Tyne, as far as the seams of Coal have yet been explored in that direction. 

 The sub-division west of the meridian of Newcastle, coloured buff" and 

 blue on the Map, extends from the line of separation between the col- 

 lieries, on the two rivers, to the south, to the crop of the several seams 

 to the west and north. I have found it necessary to separate this sub- 

 division into two parts, viz. the Tanfield and Ryton districts, as will 

 appear afterwards. 



THE WEAR. 



The sub-division east of the meridian of Chester-le Street, coloured 

 green on the Map, and which I call the Houghton-le-Spring sub-divi- 

 sion, extends from the line of separation, between the rivers on the 

 north, as far to the south of the Wear as the Coal has yet been explor- 

 ed in that direction — say to Shadforth. The sub-division west of 

 the meridian of Chester-le- Street, coloured yellow, extends from the 

 Tyne district on the north, to the Auckland country to the south, and 

 to the crop of the seams to the west.
