PRELIMINARY REPORT ON PEAT.

system, except where prefatory pages numbered with such figures have to be cited.
The system just described is essentially that used by most American botanists (outside of New England) at the present time, and its advantages over the awkward and antiquated methods of using Roman Volume numbers, parentheses, the abbreviation pp., etc. and sandwiching dates in between volume and page numbers, as still practiced by several other classes of scientists, ought to be self-evident.
Bulletins, monographs, and annual reports of geological surveys, proceedings oT learned societies, etc., are treated in about the same way. Where a work cited forms a volume by itself the total number of pages and illustrations-instead of the first and last-and the city where published are usually given.
The names of authors are arranged alphabetically, and where two or more papers by the same author are mentioned these are arranged chronologically.
GENERAL WORKS.
ASHLEY, G. H. The maximum rate of deposition of coal. Econ. Geol. 2: 34-47.
f. 2-6. 1907.
Contains valuable data on the rate of accumulation of peat.
BARTLETT, H. H. The submarine Chamaecyparis bog at Woods Hole, Massachusetts. Rhodora II: 221-235. pl. 82. Dec., 19o9.
An interesting study of the development of a peat bog, which has some bearing on Florida problems.
BASTIN, E. S., and DAVIS, C. A. Peat deposits of Maine. U. S. Geol. Surv.
Bull. 376. 127 pp., 2 plates, 20 figs., and folded map. 19o9.
Reviewed in Jour. Am. Peat Soc. 2: 73-74. 1909.
BEYER, S. W. Peat deposits in Iowa. Iowa Geol. Surv. 19: 689-733. "1909.",
(1910).
Contains many analyses and a bibliography of Iowa peat (the latter compiled by J. H. Lees). Although the author makes no record of the fact, summer is the wet season in Iowa, as in Florida, and this has doubtless favored the accumulation of peat in a comparatively dry climate. BULASK, F. J. A brief history of peat development in Michigan. Jour. Am.
Peat Soc. 1: 30-33. 1908.
CAMPBELL, M. R. Peat. U. S. Geol. Surv. Mineral Resources i906: 121141212.
1907.
Contains a brief mention of Florida peat, among other things.
