In 1881 two furnaces were erected at Asfordby, near Melton Mowbray ; but 
much of the iron-ore obtained in the district is sent away to be smelted. 
Mr. E. Wilson has calculated that where the available thickness of workable 
ore is 6 feet, the yield would be about 12,000 tons of ore, and 4,000 tons of 
metallic iron per acre.* 
The Middle Lias ironstone lias been worked at Tilton-on-the- 
Hillj Holwell, Wartnaby, Long Clawson, Eastwell, Stathern, 
Eaton, and Harston, in Leicestershire ; at Woolsthorpe and 
Denton, south-west of Grantham, and at Caythorpe and Leaden- 
ham, between Grantham and Lincoln. In structure the rock is 
more or less oolitic ; but some specimens show only organic 
fragments that have been replaced by iron-ore.
