112 KELL : SECTION AT BARROW COLLIERIES, WORSBRO'. 
The sod for commencing the sinking of the Barrow pits 
was cut on the 4th of June, 1873. 
Nothing worthy of notice took place until reaching the 
blue bind, just above the Kents thick coal, where a heavy- 
feeder of water was met with. The seam of coal, 10 inches thick 
on the Hoyland section, corresponds. I think, with the Kents 
thick coal on the Barrow section. Several layers of dark 
and blue bind were passed through before reaching the next 
thin seam of coal, which is also found at Hoyland, although 
rather thinner. A throw found at a depth of 20 yards con- 
tinued for 169 yards down the shaft. We have again dark 
and blue bind, more or less strong, and a good deal inter- 
mixed with ironstone down to the Barnsley seam, which is 
met with at a depth of 91 } T ards, but had been previously 
worked by S. J. Cooper, Esq. 
As you will notice from the sections, I have taken the 
Silkstone seam as the datum line throughout, and which 
seam is found at a distance of 378 and 376 yards respectively 
below the Barnsley bed, at the Barrow and Hoyland Collieries. 
Between the Barnsley seam and the Swallow Wood, met 
with at a depth of 151 yards, and 3 feet thick, four thin 
seams of coal are passed through, which are also found at 
Hoyland, shewing the regularity of the strata ; but a short 
distance above the Swallow Wood, a very hard stone, 5 yards 
thick, was met with. 
At the Rockingham Colliery, the Swallow Wood is found 
at a depth of 22 yards, and about 2 feet 8 inches thick. 
About 15 yards of rather strong material, including 6 
inches of cank, was sunk through, before reaching the next 
seam of coal ; but there is no trace of this cank at either 
Hoyland or Rockingham. A few yards deeper and we enter 
the Lidget rock, which appears to vary much in thickness, 
and I am happy to say, bearing in mind the difficult}' of 
penetrating such a very hard stone, that we had only 48 feet
