LIST OF WORKS AND AUTHORS CITED. 
The object of this alphabetical list is to permit convenient reference to authorities 
without either deforming the pages of the present work by footnotes or cumbering 
the text with more or less abbreviated indications of editions, volumes, and pages, as 
well as titles and names, which in some cases would have required many repetitions. 
The list is by no means intended as a bibliography of the subject, nor even as a state- 
ment of the printed and MS. works actually studied and consulted by the present 
writer in the preparation of his copy. The details and niceties of bibliographic 
description are not attempted, the titles being abbreviated, except in a few instances 
where they are believed to be of special interest. The purpose is to include only the 
works which have been actually quoted or cited in the text, and, indeed, not all of 
those, as it was deemed unnecessary to transfer to the list some well-known works 
of which there are no confusing numbers of editions. When a publication is cited 
in the text but once, sufficient reference is sometimes made at the place of citation. 
When it would seem that the reference should be more particular the work is men- 
tioned in the text, generally by the name of the author, followed by an italic letter 
of the alphabet in a parenthesis, which letter is repeated in the same fourm under 
the author’s name in the alphabetical list followed by mention of the edition from 
which the citation was taken, the number of the volume when there is more than 
one volume of that edition, and the page; also a reference, when needed, to the 
illustration reproduced or described. 
Example: When the voluminous official publication of Schoolcraft is first quoted 
on p. 35, the reference is to p. 351 of his first volume, and the name ‘‘ Schooleraft” is 
followed by (a). On turning to that name in the list there appears under it a note of 
the work and the letter (a) is followed by “1, p. 351.” The references to this author 
are so many that all the letters of the alphabet are successively employed—indeed, 
some of them do duty several times, as several references in the text are to the same 
page or plate. Thereferences to this single author would therefore have required at 
least thirty footnotes, or corresponding words in the text, instead of thirty italic 
letters divided between the several places of citation. 
The abbreviation and simplicity of the plan is shown where there are many edi- 
tions of the work cited. One of the most troublesome for reference of all publica- 
tions is that of the Travels, etc., of Lewis and Clarke. The letter (a) after those 
names on p. 419, repeated under the same names in the list, refers to p. 66 of the 
edition specified. 
When the italic letter in parenthesis precedes the title of a work in the list, 
reference is made to that work as a whole without specific quotation. So also 
when no such italic letter appears. Occasionally the title and imprint of a maga- 
zine or other continuous publication appears in the list without note of volume 
and page. This occurs where the authority is noted elsewhere, generally more than 
once, with only curt reference to the serial publication, and is intended to avoid repe- 
tition. 
The simple scheme is designed, while avoiding bibliographic prolixity, to give 
practical assistance to the reader in finding the authorities cited, when desired. 
Scientific pretense has sometimes been sacrificed for simplicity and convenience.
