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 amount of liquid nitro-glycerine between the webs. Hehence concludes that the gelatine is best made by first mixing the nitro-cottonthoroughly in the cold with part of the nit ro-glycerine. and then after gelatin-ization adding the rest of the nitroglycerine. It is claimed that in this way J See Nos. 209, 213,.
