The explosions at the Oaks and Talke Collieries destroyed more

than five hundred•lives, and subscriptions exceeding 4,0001. have been received for the bereaved families. It is now ascertained that the cause of the Talke explosion was the use of a naked light by a blacksmith, who was found with his head blown to pieces and his candle near him. These horrible accidents have revived the discus- sion as to the best methods of prevention, and Professor Tyndall suggests the lighting of the works by electric light, the rays being directed by reflectors. This light will shine in a closed vessel. Would it not be possible to light a coal mine thoroughly and cheaply with coal gas, the flame being enclosed in the Davy lamp, as that of the candle is now ?
