The opinion that a youth killed by a fall of stone in Cortonwood Colliery on November 16th ought not to have been allowed under the roof until timber had been re-set was expressed by the Sheffield District Coroner (Mr A. P. Lockwood) at an inquest at Wath on Saturday, on Arnold Hodgkiss (19) , haulage hand, of 25, Concrete Cottages, Brampton.
