To the south of Belvoir the Marlstone Rock is exposed in 
the quarries of Woolsthorpe, Knipton, and Branston, and in 
all of these the junction of the ferruginous and arenaceous 
beds is very sharply defined. On the high ground opposite 
Belvoir Castle the Marlstone is worked in a field south of 
Woolsthorpe Cliff Wood, by the Stanton Coal and Iron 
Company. Throughout this extensive area, that is to say 
between Hoi well and Scalford on the south, and Woolsthorpe 
and Denton on the north, or broadly speaking, in the district 
lying between Melton Mowbray and Grantham, the Marlstone 
Rock maintains an average thickness of from twenty-five to 
thirty feet. Over the greater part of this area the upper or 
iron-bearing beds, generally in a thoroughly weathered or 
oxidised and friable condition, very favourable for working, 
are well represented. It is in the above district that the 
Marlstone is now coming most extensively into the market as 
an iron-producing rock. Towards this end, very material 
assistance will be rendered by the new mineral lines of the 
Great Northern Railway, namely the Eaton and Eastwell 
branches of the Waltham branch, now rapidly approaching 
completion, the Woolsthorpe branch of the Nottingham and 
Grantham line, with its projected extension through Denton 
to Harston, and by the Midland Railway Company’s Holwell 
Extension branch of their Nottingham and Melton line. At 
the present time the ironstone is being worked by the Holwell 
Iron Company, the Eastwell Iron Company, the Stanton 
Coal and Iron Company, the Staveley Coal and Iron Company,
