place to state the economic uses of these valuable beds, as few persons appear to 

 be aware of the many purposes to which they are applied. The upper beds of 

 limestone, which are usually of a light colour, are polished, cut into squares, and 

 employed for paving ; the grey limestones are prepared in the same manner, and 

 likewise used for paving ; hence they are called in Warwickshire the " paving- 

 beds." In flooring halls, the light and grey squares of these beds, laid diagonally, 

 produce a very good effect and form a durable pavement. The shales are 

 burned in kilns, and ground between cylinders to a fine powder ; by this means 

 a first-rate cement is prepared, which is largely used in the Midland Counties, 

 and is sold at the works for one shilling a bushel, or at the rate of four shillings 

 per barrel.
