3; and in _Ancient Monuments of the Mississippi Valley_, by E. George Squier.

22. Throughout this writing I have often felt the need of some sort of compendious work to guide me in my researches, and in all the collection of my works upon the subject I have found Mr. Baldwin's _Ancient America_ the most useful; and should the readers of these chapters desire a special work upon the subject of American antiquities I do not think they could find a single book on the subject which would be more satisfactory than the little work (293 pages) here referred to; and since I have quoted so extensively from it, I cite the following to show in what esteem Mr. Baldwin is held by one who is the author of the most elaborate work on the subject of American antiquities: "Mr. Baldwin's most excellent little book on _Ancient America_ is the only comprehensive work treating of this subject now before the public. As a popular treatise, compressing within a small duodecimo volume the whole subject of archaeology, including, besides material relics, tradition, and speculation concerning origin and history as well, this book cannot be too highly praised." Bancroft's _Native Races_, vol. IV, 2.

23. _Ancient America_, pp. 20-24. Rev. J. G. Fish speaking of some of these North American mounds declares that "the summit level of some of them contains more than twelve acres. At their base they appear like walls stretching up to heaven and it requires but a stretch of the imagination to fancy them mouldering bastions and ramparts of some ancient fortress." _Bible in the Balance_, p. 237.
