Non-Smithsonian authors should address inquiries to the appropriate department. If submission is invited, the following format requirements of the Press will govern the preparation of copy. _Copy_ must be typewritten, double-spaced, on one side of standard white bond paper, with 1-1/2" top and left margins, submitted in ribbon copy with a carbon or duplicate, and accompanied by the original artwork. Duplicate copies of all material, including illustrations, should be retained by the author. There may be several paragraphs to a page, but each page should begin with a new paragraph. Number all pages consecutively, including title page, abstract, text, literature cited, legends, and tables. A manuscript should consist of at least thirty pages, including typescript and illustrations. The _title_ should be complete and clear for easy indexing by abstracting services. Include an _abstract_ as an introductory part of the text, followed by an identification of the _author_ that includes his professional mailing address. A _table of contents_ is optional. An _index_, if required, may be supplied by the author when he returns page proof. _Headings_ are to be used discriminately and must be typed with extra space above and below. For matters of general style (including bibliography and footnotes or notes) follow _A Manual of Style_, 12th edition, University of Chicago Press, 1969. For more detailed treatment on footnotes and bibliography see Citation Style Manual prepared for MHT publications (October 1963). Use the modern order of citing dates: 29 February 1972. Simple _tabulations_ in the text (e.g., columns of data) may carry headings or not, but they should not contain rules. Formal tables must be submitted as pages separate from the text, and each table, no matter how large, should be pasted up as a single sheet of copy. Use the _metric system_ instead of (or in addition to) the English system.
