A scientific expert was appointed to the post of superintendent of land mines. In the first place, he had to perform the difficult work of prospecting and discovering new mines on plains and mountain slopes. He had to examine and infer from slags, ashes and other such indications whether a mine had been exhausted or not. This department was manned by several other experts, as also by mining labourers. It was also equipped with the necessary scientific apparata.
