332 THE COLLIERY GUARDIAN. February 12, 1915. In the Freystrop district the lowest vein that has been worked is generally identified as the .Kilgetty Vein. The Catshole Vein has been occasionally worked. The name Catshole Vein is sometimes applied in the Reynalton and Loveston district to a poor vein that overlies a s-trpng sandstone at some distance above the Lower Level Vein, but this is totally distinct from the Catshole Vein of the district to the east. The Lower Level Vein has been more worked than any of the lower veins; it has been recognised with certainty as far west as Loveston Cross, and a vein which probably corre- sponds with it can be traced for about' two miles to the west of that place. It is characterised especially by the abundance of lamellibranchs, chiefly Carbonicola aquilina (J. de C. Sow.), in the roof. At Reynalton the thickness of measures between the Lower Level and the Catshole Vein or the 27-fathom rock, which crops at Cloverhill Farm, appears at first sight exceptionally great. In fact, if the dips be relied on,r the vertical distance between the Catshole Vein, near Hare Stepis, and the Lower Level Vein at Reynalton would be at least 160 yds., instead of 26 yds. as in the New Hays shaft. But the intervening ground shows a •succession of strike-ridges and deep, strike hollows in each of which there is some indication of a coal. These features do not exist in the ground to the east, and their incoming here is probably due to overthrusting; in fact, the Lower Level Vein is said to crop twice to the north of Reynalton. ; About half a mile to the west of.Verbeston a vein has been worked near the crop. It seems to correspond in position with the Lower Level Vein, but no lamelli- branchs were found, though some fish remains, includ- ing Coelacanthus sp., a mesolepid scale and a palseo- niscid, were collected by Mr. J. Pringle on one of the tips a quarter of a mile south-east of Campshill. In the Freystrop district the second vein above the supposed Kilgetty Vein is sometimes referred to as the Bon Ville’s Court Vein, which is another name for the. Lower Level Vein in the Saundersfoot district. It is. probably repre- sented among the thin veins worked near the crop in and to the west of Martietwy Wood. Another vein, which is called the Little Rock Vein, was worked on the downthrow side of the Trewern Fault north-east of Shipping, and an old shaft 200 yds. from the farm in. that, direction was said to be 32 yds. to the vein. There ,,are also shallow workings at Shipping on what is probably a higher but unnamed vein. ' (3) Between the Erroxhill and the Harbour Faults.—• The Erroxhill Fault is the name given to a more or less continuous disturbance which runs from the coast near Amroth, by 'Sardis Mountain, along the south side of Ring’s Moor, and thence down the Cresswell Valley. The throw of the fault is estimated at 93 yds. near Sardis. Mountain, but at more than .200 yds. westwards of the junction with the Wiseman’s Bridge Fault. The Harbour Fault runs from Saundersfoot Harbour to the south of Jeffreston, and has the effect of a downthrow to the north, but is probably a powerful overthrust from the south. The belt of ground lying between these two lines of disturbance occupies a central position in the coalfield, and includes the newest measures existing in this part of Pembrokeshire, and the majority, though not all, of the crops of the Timber Vein. Within it much coal has been raised from the Rock, Timber, Lower Level, and Kilgetty veins, but the last two alone are now worked, in the Bonville’s Court Colliery. The syncline at Woodside and the anticline at Hean Castle have already1 been noticed. The anticlinal. axis ranges north-westwards, a little south of the Speculation Pit, and on its southern flank the sandstone overlying the Lower Level Vein forms a broad outcrop dotted over with old shallow shafts. The Kilback shaft, 150 yds. west of the castle, reached the vein at 44 yds. depth on the northern flank of the anticline, and another, 350yds. north-west of Coppet Hall, reached .it at 34 yds. depth on the southern flank. To the south of the anticline there are two crops visible south-east of Kiillawen, both probably in Stinkard veins, and a line of old crop workings in a stream 200 yds. south-east of Netherwood in an unknown seam. At the head of this stream the Ventilating Pit of the Bonville’s Court Colliery was sunk in 1846. The Ventilating Pit appears to have started about 50 ft. below the horizon of the Timber • Vein. What is sup- ' posed to be that vein crops in the railway cutting west of the pit in a position which accords with that view. The Tower Pit was commenced in the ’crop of the "Rock Vein of the Timber Vein series. A Stinkard, 10 in. thick, was traversed at 228 ft., the Rock Vein of the Lower Level Vein series at 332 ft., the Garland Vein at 474 ft., and the Lower Level Vein at 504 ft. In 1876-78 the shaft was carried down to the Kilgetty Vein. ■The shaft is situated in a belt of ground which is limited on the south by the Harbour Fault, and is itself traversed by innumerable folds and overthrusts, so far as regards the surface. At a depth, however, the Lower Level and Kilgetty veins, though not free from disturb- ance, have proved to be comparatively regular and continuous. The southern limit referred to is, shown on the map as a continuous line of overthrust ranging from Sanders- foot Harbour, between Cold Inn and East Williamston, and thence to the south of Jeffreston. This line may be regarded as a diagrammatic representation of what is probably a complex of thrusts, but to trace out indi- vidual thrust planes is impossible. The crops within this belt are traceable only where the coals have been “ smutted,” but this method of working was so prevalent in former years that probably few crops, of the Timber Vein at least, have been missed. The Foxhole Pit, sunk in 1882-3, but now abandoned, is 350 yds. south of the Tower Pit, and close to the southern margin of the belt of ground under description. The Moreton Colliery was situated in this belt of ground near Wooden, and about 500 yds. west of the railway. The downcast shaft reached the Rock Vein at 55 fins., N.Sid* S.Sid. '“’□to#’ . U
