Mr. Rowland Childe’s large diagram represents a true 
section of this West-Riding coal field, which is twenty- two 
miles in length. It is drawn to a longitudinal scale of six 
inches to one mile, and vertically sixty feet to one inch. It 
is taken from the Kirkburton colliery on the S. S. W., by 
the Emly Moor, Flockton, Denby Grange, Ossett, Round 
Wood, Methley, Kippax, and Garforth collieries, to near 
Micklefield on the H. N. E. 
The thick black lines in the section are the coal beds in 
the carboniferous rocks, and the vertical ones the faults, 
throws or dislocations, breaking through the coal measures, 
forming walls between them, and dividing them into 
chambers. 
From Kirkburton to near Wakefield is the first great 
chamber or field of coal, the seams in which dip down east- 
wards considerably below the surface of the ground. From 
Wakefield to Methley the beds of coal lie nearly level. 
From Methley to Kippax they are concave or slightly dish- 
shaped. From Kippax to Garforth the beds of coal rise very 
rapidly again to the ground, until near Micklefield they crop 
out nearly at right angles, or unconformably against the 
Magnesian Limestone. 
At the Kirkburton colliery the Halifax soft coal, the 
lowest bed in the series of coal measures resting on the Mill- 
stone Grit, could be reached by the shaft of that pit at a 
depth from the surface of the ground of about 303 yards. 
At the Victoria colliery, near Wakefield, that bottom bed 
would require a shaft to reach it of 7 67 yards, whilst under 
the Pontefract Park it will probably be necessary to sink 
1,016 yards to exhume the coal, and at the Denaby Main 
colliery 1,204 yards ; until at a little distance H. N. E. of 
Micklefield, the Low Moor and Halifax beds crop out al- 
together against the Magnesian Limestone, and beyond that 
point, and in that direction, no coal would be found.
