As no diplomatic history of Chile has been published the well known historian Francisco A. Encina has culled from his monumental 20 volume Historia de Chile those paragraphs and chapters relating to the Argentina-Chile negotiations concerning their boundary dispute from its beginnings, and more especially from mid-century through the Treaty of 1881. There are no chapter divisions in the book, only the same titles of sections taken from the larger work. Less than a hundred words have been changed and one footnote added. There is an introduction by another person which sets the stage. The materials in this volume are taken from the Historia de Chile as follows: XII, 609-620 [pp. 1-12]; XIV, 110-119 [pp. 12-22]; XV, 35-44 [pp. 22-31]; chap. ii excluding pages relating to Peru and Bolivia [pp. 31-97]; chaps, xii-xiii [pp. 97-168]; XVI, chap. xxii [pp. 169-221]; pages 502-513 [pp. 221-233]; XVII, 273-279 [pp. 233-240]; pages 431-444 [pp. 240-250]; pages 576-593 [pp. 250-268]. There is an index.
