This is a very rare treatise on the lead mines of the Alston Moor region of Cumbria, England. Wallace (1832-?) divides his work into two books. The first covers the first 95 pages and is devoted to theories of the formation and geological structure of the mining districts of Alston Moor. He discusses the deposition of the various strata, their uplift and structure, theories concerning the formation of the types of veins, their present trends and characteristics of each type of vein, distinguishing features of crosscutting veins, and Werner's views on the veins. Book two covers the remainder of the work and is devoted to the current understanding of the laws thought to regulate metal deposits as illustrated by the lead veins of Alston Moor. Wallace examines each lead deposit at Alston Moor, gives an analysis of the veins characteristics, compares the vein to the surrounding country rock, compares the deposits to each other in terms of size, characteristics and mineralogy. He then provides an analysis of the theories of vein formation based on his understanding of the lead veins of Alston Moor. The plates are tinted views, and colored sections of the major veins.
