232 Mr, Budvle's Synopsis of the Newcastle Coal Field. 



east and west. From its commencement at the Chirton Pit, it passes 

 through Flatworth Pit, WilUngton Bell and Brown Pit, Wallsend C 

 and D Pits, Bigge's Main A Pit, Heaton High Pit, across the Ouse 

 Burn and to Jesmond Middle Pit. Then across the Town Moor to 

 the Cow-gate, through the Fenham division of Benwell Colliery, and 

 across the Main Dyke, at about half a mile north east of Denton-hall, 

 and then in a direct line to the Coronation Pit at Walbottle. The 

 linear direction in this has been better preserved than in any of 

 the other sections. The deepest part of this section is between the 

 two Dykes on the west side of the Flatworth Pit, the High Main Coal 

 there being about V25 fathoms from the surface, bringing in the 

 18 fathom Post, which originates in Jarrow, and is described in Sections 

 No. 1 and 4. Below this we have the Grindstone Post, the several di- 

 visions of the '70 fathom Post, and the Main Post. 



The Grindstone Post continues in from this point to Heaton High 

 Pit, when it crops out and does not again appear further west. To the 

 eastward it crops out before it reaches Chirton Pit. 



In describing the various dislocations in this Section, I will take the 

 Main Post as my standard. At the Chirton Pit this Post is found in 

 full perfection, at 40 fathoms from the surface, where it is 10 fathoms 

 thick. It dips rapidly, and in an increased ratio from this pit to an 18- 

 fathom down-cast Dyke, at the Flatworth Pit. After being thrown down 

 by this Dyke, it runs, with a very gentle dip, for about 320 yards, 

 where it is again thrown down o fathoms. It then goes on, still dip- 

 ping very gently for 335 yards, where it meets with a 9-fathom upcast. 

 This is the point of the greatest depression, as the strata rise both east 

 and west from it, and answers to the point of the greatest depression un- 

 der Jarrow Slake, as noticed in Section No. 4. The Main Coal here 

 is only 114 fathoms below the sea level, while under Jarrow Slake it is 

 152, which shows a rise in the seam of 38 fathoms between the two 

 points in a northerly direction. After passing this 9-fathom upcast, 

 the strata run without interruption, with a gentle rise, through the 

 whole extent of Willington and Wallsend Collieries into Bigge's Main, 

 where they are thrown down by a 9-fathom Slip Dyke to the west. The
