This reprint of a rare and obscure pamphlet, originally published by Thomas Fiddick of Camborne in 1913, details the various experiments which he undertook whilst dowsing for mineral lodes in his native Cornwall, as well as giving a potted history of mineralogical dowsing in the area. It also gives details of his "Dowsing Cone" and instructions for its use. This book is an invaluable resource for those who study or practise the art of rhabdomancy, or for those who wish to learn more concerning the history of mining in Cornwall.
