on the deep side they hit the Brooch coal in advance of the Thick coal, as in the diagram. Moreover, there were certain wet beds (1 in diagram), beds from which water came out, above the Brooch coal. Now, in a shaft (B) sunk to the Thick coal on the crop side of the fault, these beds were not passed through, and the shaft was quite dry; while in the shafts (C) farther from the fault, they were met with, and the shafts were quite wet. This likewise agrees with the diagram, and the facts are explicable only on the supposition of its correctness. Job Taylor likewise assured me that on the deep side of the fault the coal was "pinched" towards the fault by the descent of the roof, as in the diagram. If the reader will draw perpendicular lines from the ends of the Thick coal No. 3, where they are traversed by the fault, up to the surface, the space between those lines will give him the width of the fault according to the common notions of it.
Shut End faults.[1]—A little north-west of the commencement of the Corbyn's Hall fault, two parallel faults strike nearly north from the Boundary fault near the Standhills, one throwing down to the west about 300 feet, another up to the west 150 feet, with a complicated and broken piece of ground between them. They coalesce or come very near together, just south of the Dudley and Kingswinford turnpike road, and thence proceed as one fault north-by-east, just west of the Shut End furnaces, with a total downthrow to the west of 180 feet. This fault, called the Shut End fault, is believed to run by Askew bridge up to the Russell's Hall fault there.
Tansy Green Trough.—It sends a considerable branch from Shut End by Cooper's bank, nearly to the Graveyards, which has a downthrow to south-east of about 120 feet. This branch forms a trough with the northern or north-eastern extension of the Corbyn's Hall fault, both running nearly east and west, and having a downthrow of about 90 feet towards each other.
Even at Shut End the fault is not a single fissure, like the Corbyn's Hall fault, but a wide dislocation made up of a number of steps or smaller fractures (see Horizontal Sections. Sheet 25, No. 7). Mr. Colly, the ground bailiff, was kind enough to give me the details of a gate-road that was driven through the fault, starting from the Thick coal on the "crop" side of it, i.e., the upcast side. The gate-road was horizontal, but they met, in driving, with beds lying at various angles, of which the following are the details:-—

This red ground No. 16 was outside of the faulty ground, and at the end of the 33 feet they sank a "jackey pit," and found the Two-foot coal which they had just previously passed through lying horizontally 22 feet below them. The whole length of the gate-road was 261 feet,
