Part of a 1910 plan, measuring about 8 feet by 5 feet, of the Beeston seam at Water Haigh colliery under the Calverley estate.
The Beeston seam was the deepest in the pit and was in two parts - the Low Beeston at 352 yards underground and the Top Beeston, at 349 yards. There were 4 feet 7 inches of coal in the top seam with a one inch band of dirt in the middle. The lower seam had two bands of coal - a 2 feet layer separated from a 1 foot 4 inches layer by 2 feet of dirt. There were similar plans for each of the seams at all the collieries on the Calverley land, including West Allerton, Rothwell and Newmarket.
