Note 59 — Appendices

The following passage from Townsend's Journey through Spain (Vol. II., p. 56), is curious as showing where jet was formerly found in this Peninsula. “When I returned to Oviedo, a gentleman gave me a collection of amber and of jet, of which there is great abundance in this province: but the two most considerable mines of it are in the territory of Beloncia, one in a valley called Las Guerrias, the other on the side of a high mountain in the village of Arenas, in the parish of Val de Soto. The former is found in slate, and looks like wood: but when broke, the nodules discover a white crust, inclosing yellow amber, bright and transparent. Jet and a species of kennel coal, abounding with marcasites, universally accompany the amber.”
