The lamps' room at Ewald colliery !

In this picture you can see the lamps' room at the German Ewald colliery. After the shift the lamps are stored in the shelves and during that the accumulators are recharged. In earlier times the lamps made it possible to control whether all miners returned from their shift or not, because each miner had a special number and by this it could easily be identified who did not return, maybe because of an accident or for another reason.

I received this picture from Petra and her husband, so that I can present it to you. Thank you both for the support. If you want you can contact Petra by sending her an e-mail.
