358 FLORIDA GEOLOGICAL SURVEY-THIRD ANNUAL REPORT.
BIBLIOGRAPHY.
This is divided into two parts; the first including works relating to peat of other states or peat in general, and the second, those relating to the geography or peat resources of Florida.
Much more extensive bibliographies than this, which will be useful to any one who wishes to go, into the subject deeply, can be found in several of the works named in the first list. Most of the older books cited by other writers on peat have not been acces sible to me, however, and this list does not aim to be complete, but merely to give references to a few of the more important recent papers on the subject. Those relating exclusively to peat machinery or methods of utilization are not mentioned.
The second list includes titles of nearly everything that has been published (outside of newspapers and other ephemeral publications', on Florida peat, as well as several -important works r9f a geographical nature which have been consulted in preparing the descriptions of the natural divisions of the state. (A few of the papers in the first list also contain incidental references to Florida.) ManNy other more or less geographical titles can be found in the bibliography of Florida geology by Dr. Sellards, in the first annual report of this Survey.
For the benefit of readers who may not be familiar with modern methods of bibliographic 'Citation a brief explanation of the system used will not be out of place. In the case of magazine articles, the title is followed by the name of the magazine (often abbreviated), the volume number-or year for annual publications with no separate volume number-in Arabic; a colon; the first andl last pages of the article, connected by a short dash or hyphen (even if the article 'occupies only two pages) ; the numbers of the illustrations, if any (p1. meaning plates and f., figures in the text) ; and finally the date (giving the real date when known, which is often different from the alleged date, especially in State and government publications and in magazines). In a few cases (Science for example) where a magazine has changed hands and taken a new start, with new volume numbers, a series number has to be used, and this is placed before the volume number, in Roman figures, followed by la period.* This is the only use made of Roman numerals in thi-~
