They may havebeen caused by dropping a lead apron into the It is advisable thatthe machinery be not running whilst the trough is being filled. If the stirrersare driven electrically there should be an automatic cut-out to the motorto prevent the use of too much force. Starting from the theory that blasting gelatine has a webbed structure,\V. A. Hargreaves, Inspector of Explosives in South Australia, has arrivedat the opinion that it does not possess sufficient sensitiveness unless therebe a considerable am
