pasted on proper page, and point of insertion 
should be clearly indicated. 
Original copy and one carbon copy of manu- 
script should be submitted. The author should 
retain a carbon copy. Although due care will be 
taken, the editors cannot be responsible for loss 
of manuscripts. 
Introduction and summary. It is desirable to 
state the purpose and scope of the paper in an 
introductory paragraph and to give a summary 
of results at the end of the paper. 
Dictionary style. It is recommended that authors 
follow capitalization, spelling, compounding, ab- 
breviations, etc, given in Webster's New Inter- 
national Dictionary (unabridged), second edi- 
tion; or, if desired, the Oxford Dictionary, Ab- 
breviations of titles of publications should, if 
possible, follow those given in U. S. Department 
of Agriculture Miscellaneous Publication 337* 
Footnotes. Footnotes should be used sparingly 
and never for citing references (see later). 
When used, footnotes should be consecutively 
numbered by superior figures throughout the 
body of the paper. Footnotes should be typed 
in the body of the manuscript on a line imme- 
diately below the citation, and separated from 
the text by lines running across the page. 
Citations of printed sources. All references cited 
should be listed alphabetically by author at the 
end of the paper, typed double-spaced. Refer- 
ences to books and to papers in periodicals 
should conform to the following models:

In the text, sources should be referred to by 
author, date, and page, as follows: 'It was noted 
(Rock, 1916: 18) that . . or "Rock (1916: 
21-24) says . . 
Quotations. Quoted matter of fewer than five 
printed lines (about 200 characters) should be 
given in the text in the usual form, using double 
quote marks. Longer quotations should be set 
flush with left margin. The author is responsible 
for the accuracy of quoted material. 
Numbers. Decimals, measurements, money, per- 
centages, time; enumerations in which any figure 
is 10 or over; and isolated enumerations of 10 
and over should be given in Arabic figures, 
rather than spelled out, except when the number 
begins a sentence. 
Illustrative Matter 
Illustrations should accompany manuscript, on 
separate sheets. Often more valuable than a 
photograph is a good line drawing, which may 
be reproduced by the zinc etching process. 
Figures and graphs. Copy for figures and graphs 
should always be drawn large enough to allow 
for at least one-third reduction by the engraver. 
Copy should consist of carefully prepared line 
drawings in one color only, drawn in India ink 
on plain white drawing paper or tracing cloth. 
Co-ordinate paper with lines in light blue (a 
color which will not show in a photograph) may 
be used; but co-ordinates which should appear 
in the finished graph must be drawn in India 
ink. If original figures may not be conveniently 
submitted with manuscript, duplicate rough 
sketches or photographic prints may be fur- 
nished to aid the editors in their decisions. 
It is strongly urged that an indication of scale 
be incorporated as a part of all drawings in 
which magnification and size are critical con- 
siderations. 
Photographs. Photographs should be chosen for 
clarity in portraying essential information. 
They should be printed for contrast, on glossy 
paper, and should be sent unmounted. They 
should be identified with serial number written 
in soft pencil on the back to correspond with 
list of captions. 
Tables. Tabular matter should be kept to a mini- 
mum. Each table should be typed on a separate 
page, and its position indicated on the manu- 
script. 
Captions. Readily identifiable captions for fig- 
ures, graphs, photographs, and other illustrative 
matter should be supplied. 
Proofs 
Proofs should be corrected Immediately and 
returned at once to the Editor-in-Chief. All 
queries on proofs should be answered. 
Reprints 
Reprints or separates should be ordered when 
proofs are returned. Each contribution will en- 
title the author (or group of authors) to 50 free 
reprints, without covers (these 50 to be divided 
where more than one author is named). At the 
time proofs are returned, authors may order 
additional reprints, with or without covers, at 
prices indicated in a schedule accompanying 
proofs.
