 sary to a clear understanilinL' of tiie text can be accepted for i)ub- 

 lication.

 good to carry them satisfactorily, the illustrations will be run as text 

 li^ures. Otherwise [ilatcs will be used. The maximum length for 

 full-|)a^fc illustrations is TVij inches, and the maximum width is 4Vs

 of the Ollice of Information of the department unless tiic bureaus 

 or stations can do it properly. 



All photographs should be submitted unmounted, and in an 

 envelope. 



On the back of each illustration there should be given the plate 

 or figure number ami the title of the accompanying nuinuscript. 



Inclosed with the illustrations there should be a sheet containing 

 a typewritten list of all the legends. In addition, the legends for 

 the text figures (but not for the i)lates) sliould be inserted at those 

 places in the text where the illustrations are to appear. 



Text figures and plates should each be numbered in the order 

 in which they are referred to in the text. 



Arabic numerals are used in numbering all text figures and plates. 



Separate parts of a text ligure or plate are placed in contiguous 

 position, instead of being separated by legends, nnd are designated 

 by Koman cajiital letteis A, B, C, etc. The parts of A. B, C, etc., are 

 designated in italic letters a, h, c, etc. 



In text references to figures or j)lates havinii these parts, the 

 numbers and the letters should be separated by couimas, thus: 



'•The plant shown in Plate O. B, a. * * * "' or in "Figure 10, 

 C,h, * * *r 



Also: "As may be seen in the infestctl phmt (j)l. .">. D. <?)," or 

 "(fig. 8, A, ^/)."^ 



The woids "ligure*'' and "plate" are capitalized when followed by 

 the numerical designation. A\'hen references ai'c made to tlu-m paren- 

 thetically they are al)bicvi:ite(l and lowei'-cased. (See examples in 

 last paragraph.)

 erature cited"; if fewer than seven, they should be given in footnotes.
