Hartshead and Mirfield, and near the old Huddersfield and 
Leeds road, a considerable " throw" up to the South is found. 
The extent of ihis elevation is supposed to be not less than 
100 yards, which opinion is corrroborated by the levels. — 
The line of Section then intersects another outcrop of the 
* Blocking Coal,' which may be traced through the village 
of Mirfield, to the South side of the river Calder, where it 
has been worked by the Wheatleys and the Walkers. — In 
the township of Thomhill, the ground rises Southward from 
the river, and sufficient cover is obtained for the * Lime 
Coal,' or ' Wheatley's three-quarters Coal,' and the ' Crom- 
well bed,' which have been worked for many years by 
Messrs. Wheatley. I have taken many lines of water levels 
here, but I have not been able to ascertain the average dip 
of the strata, owing to their distracted state. — From this 
high ground, the line of Section descends the dell in Mr. 
Ingham's estate, where the * Cromwell bed' is worked ; and, 
further on, it crosses the outcrop of the ' Flockton Coal ;' 
then climbs the bold escarpment of ' Bradgate rock,' on 
which stands the village of Thornhill, and proceeds along a 
plain, about a quarter of a mile in length, to another 
escarpment, on the brink of which are Mr. Ingham's col- 
lieries, working the ' Flockton Thin Coal.' — A deeply de- 
nuded valley separates this cliff from the rising ground of 
Emroyd, under which Messrs. Briggs and Stansfeld are 
working a seam of coal that lies about 81 yards below the 
* Flockton Thin Coal. The levels in Emroyd Colliery ge- 
nerally range nearly East and West. — Having attained the 
summit of the Emroyd ridge, at a point about half-way 
between Overton and Middlestown, the line of Section de- 
scends into the Coxley valley ; passes through the steep wood 
on the opposite side, and goes over another hill, betsveen 
Midgley and Netherton, into the Bullcliffe Wood valley. — 
It then traverses an elevated ground, in the township of 
Bretton, crossing the Denby Dale road, at Sun Wood, and
