The nearest working collieries to the site of the hole are 
Micklefield (about 12^ miles distant in a north-westerly direction), 
and Fryston CoUieries (about 11 miles south-west), where the 
Beeston Bed is worked at depths of 750 feet and 1,620 feet 
respectively. The Coal Measures at these two places are dipping 
south-east, and it was to be expected that at Barlow the seams 
of the Lower Coal Measures would prove to be at a very 
considerable depth from the surface. The primary object of 
the borehole was to prove the existence of Coal Measures 
and the depth at which they lie in Lord Londesborough's 
estate.
