FUNGI OF WARWICKSHIRE. 
Aug., 1889. 
workable stone is to be found only within an area of some 
thirty miles long by about ten miles broad, extending to the 
east of Bath between Chippenham on the north and Trow¬ 
bridge on the south. The thickness of the stone also varies 
considerably. At Box Hill, where it is believed to reach its 
maximum, it is about 45ft., comprising 12ft. to 15ft. scallet 
or finest grained, cut for ashlar or facing purposes, 15ft. to 
20ft. corn grit, used for dressings, and 16ft. to 22ft. ground 
stone ; while at Combe Down, only a few miles distant, the 
total thickness is but about 7ft. 
A characteristic of the stone may be mentioned : it is 
very light, its specific gravity when dry being but a shade 
over 2, while the generality of rocks forming the earth’s crust 
average from 2J to 3J times the weight of water. One 
hundred pounds of dry stone will absorb only nine pounds of 
water, and a sound block will stand a pressure of seventy 
tons on the square foot without cracking.
