London, Sampson, Low, Son and Marston, 1864. The first U.K. edition of Marsh's foundational work on conservation, published the same year as the U.S. edition, and during the period that Marsh was living abroad, as U.S. minister to Italy, a post first awarded him by President Lincoln. Vastly influential: published 10 years after Thoreau's Walden and five years after Darwin's The Origin of the Species, Marsh called out human degradation of natural resources and warned of Man's outsized and lasting effects on his environment, with particular attention to the interdependency of ecosystems, or, in his words, "the harmonies of nature." This edition was typeset and printed in London. Quarterbound in green calf with gilt spine, marbled boards, endpapers, and page edges. Modest rubbing to the board edges; small numerical stamp first blank; minor foxing to endpages and margins of prelims; still a near fine example. A key volume in the history of conservation and environmentalism. [#036439] $2,500
