Produced by Marius Masi, Don Kretz and the Online Distributed Proofreading Team at http://www.pgdp.net Transcriber's notes: (1) Numbers following letters (without space) like C2 were originally printed in subscript. Letter subscripts are preceded by an underscore, like C_n. (2) Characters following a carat (^) were printed in superscript. (3) Side-notes were relocated to function as titles of their respective paragraphs. (4) Macrons and breves above letters and dots below letters were not inserted. (5) [int] stands for the integral symbol; [alpha], [beta], etc. for greek letters and [oo] for infinity. (6) The following typographical errors have been corrected: ARTICLE FORESTS AND FORESTRY: "These trees will all be of increasing importance." 'will' amended from 'wil'.
