The Slates of Wales

By F. J. North, D.Sc., F.G.S.

Preface from the original booklet . . .

WALES, with about sixty slate-mines and slate-quarries employing more than eight thousand people, produces the best slate in the world, and furnishes over eighty per cent of the total slate-output of the British Isles. It is fitting, therefore, that the National Museum of Wales should give prominence to exhibits dealing with the nature and origin of slate and its distribution in the Principality. The object of this pamphlet, prepared by the Keeper of Geology in the Museum, is to expand, in the simplest possible language, the information contained in the Museum labels into a form which may be found of use also by those who are unable to visit the collection.
