planks, which are 14in. wide and lin. thick. These planks are 

 bolted to angle iron at the corners, and are strapped with iron 

 on the sides; a rim of iron is fastened all round the outside 

 edge. The skips are weighed on one of Henry Pooley and Sons' 

 platform machines. When weighed, the skips are run into an 

 end tippler, the hooks of which catch the front axle of the 

 skip as the coal is tipped on to the screens (Fig. 65). 



Water is raised from the dip workings by a pair of rains 

 worked from the return sheave of the main haulage by gear- 

 ing, which increases the speed from 1 to 2. These force the 

 water to a water level, along which it flows to old workings, 

 which form a lodgment ; from this it is pumped to the surface

by the Tangye pumps. There are two Tangye pumps, one with 

 an Sin. plunger and 3ft. Sin. stroke, the other, which is held 

 in reserve, has a Gin. plunger and a 3ft. 2in. stroke. 



The coal is classed as forked, slack, and shandy or shovel- 

 filled. This is the only colliery in the Western coalfield that 

 makes coke. Coke is more expensive to make here than on 

 the South Coast, as the coal is harder to break up, requiring 

 about 40 per cent, more crushing power, and iii has to be 

 washed to reduce the quantity of ash, which causes a loss, be- 

 sides which the moisture has to be driven off, which takes time 

 and heat. The coke is good, and it is all consumed by W. & 

 J. Hoskins at the ironworks. To help equalise this extra
