The First Division Coals 



WOORGREENS COLLIERY 



The two Woorgreens seams, separated by 24 feet of sedi- 

 ment, are only worked at Woorgreens Colliery, a short distance 

 West of Cinderford Bridge Station, on the road to the Speech 

 House. No other seams are worked here, so the place of 

 origin of the plants to be found on the comparatively small 

 heap of this colliery is perfectly definite. The shales, how- 

 ever, are very soft and wet, and crumble away rapidly, so 

 that it is not easy to procure good specimens. For this reason 

 repeated visits, after spells of fine weather, are likely to meet 

 with greater success than a casual visit, perhaps on a showery 

 day. The commonest species to be found here are the Cala- 

 mite foliage, Calamocladus cquisetiformis (Schloth.) Plate 

 XXXVII, fig. 5, the fronds Sphenopteris {Renatdtia) chcero- 

 phylloides (Brongn.) and Pecopteris polymorpha, Brongn. (Plate 

 XXXVII., fig. 3) with the Lycopod stem Lepidodendron 

 lanceolatum, Lesq. 



Among the rarer plants are 



Annularia galioides (L. and H.) 



A. sphenophylloides (Zenker). 



Neuropteris ovata, Hoffm., Plate XXXVII., fig. 6. 



Pecopteris Miltoni (Art.), Plate XXXVII., fig. 2 



Lepidodendron Wortheni, Lesq. 



The Second Division 



The coals of the Second Division are thin seams, the 

 Lowery Seam (2 ft. i inch) being the thickest. The Starkey 

 and the Rockey Coals are the other chief coals. As a rule, 

 the collieries working the coals of the Second Division do not 

 work those of the First or Third, but they mine several seams 

 belonging to the Second Division together. The partings 

 between the seams consist of shales and sandstones, the former 

 predominating. In order to win these thin seams, enormous 

 quantities of these rocks have to be removed, brought to the 

 surface and thrown on the waste heaps. The collieries work-
