Wereless for Miners.

An invention has been brought to light which will serve to considerably minimise the dangers to which every day the large number ol underground workers are exposed. A clever German subject, Herr J. H. Reinecke, of Westphalia, has invented a system of wireless tele:graphy for use in mines. The system has been adopted at Dinnington Main Colliery in Yorkshire, where instruments have been fixed at two points and conversations have been carried on with the same ease as is the case with ordinary telephones. There is a portable instrument adapted for use in the cage whilst ascending and descending the shaft, and so a means of communication with those above ground in time of disaster has been established. By this means rescue work will be considerably facilitated, for entombed miners will be in direct communication with the pit-head, thus being able to call for assistance and give directions as to their whereabouts and the bast means of reaching them.
