A problem peculiar to mining is how to transmit radio signals through rock.

BOOK REVIEWS
Parallel experiences and narratives in the histories of South Africa and of Ireland, and the ways in which the stories of pain and of hope are shared by storytellers who guide visitors in museums and heritage sites in each context, make for an important and timely comparison. The authors reflect, in the closing pages of this book, on the relevance of museums in the twenty-first century.

He came to South Africa in 1899 as a volunteer with his Indian Regiment in the South African War (1899-1902). Afterwards, he joined the Neumann Group as their Company Secretary. The original shingle roof has been replaced with slate.
