with great advantage, particularly after the introduction of the Davy Lamp 

 in 1815, until the working of the Main Coal Seam ceased in April, 1831. 

 The working of this seam ceased before it was entirely exhausted, at the 

 time of the union strike of the pitmen in April, 1831. Those misguided 

 men, on this occasion, would not allow the shifters to go down the pit to 

 keep the workings open ; and, before the dispute was settled, the roily and 

 tram-ways had crept so close, that it was not deemed worth while to open 

 them out again.* 



7. — The Dip and Rise of the Colliery, and Slip Dykes. 



There are few fields of coal, of the extent of this colliery, which lie so 

 regular, or are so free from Slip Dykes or Hitches. 



The engine level, from the B Pit, runs first north, and then north-east, 

 till it tails out under the Parsonage House, in the village of Wallsend. 

 After crossing the 13-feet upcast to the north, which lies 165 yards south 

 from the C Pit. From this point the seam rises gently to the east, west, 

 and north. 



From the B Pit the seam dips east about 8 fathoms to the G Pit, which is 

 nearly in the bottom of a swelly, as, at a short distance to the east of the G 

 Pit, the seam takes a gentle rise to the eastward. The G Pit engine lifts 

 the water from this low level, and has, for many years, been the only en- 

 gine employed on the colliery. From these favourable circumstances the 

 colliery was easily drained. 



The principal slip dyke is called the Delight Pit Dyke, so named 

 from having first been discovered in the Delight Pit, Walker Colliery. 

 This dyke runs quite through the colliery, from west to east, passing at 

 150 yards south of the A Pit, where it is a down-cast of 5^ fathoms, and at 

 88 yards south of the G Pit, where it is a down-cast of 8^ fathoms. The 

 coal on the south side of this dyke, in the A Pit, was worked by a stapel 

 and horse gin ; but the G Pit was sunk %\ fathoms below the seam, and the 

 coal was wrought there by a stone drift, driven from the pit, which cut the 



* By this act of violence a number of old and infirm men who had been employed at 

 shift-work (ridding stones and lowering the tram-way, &c.) in the pillar working, were 

 thrown out of work, to their great distress.
