Illustrations are extremely valuable adjuncts to scientific papers 

 and their free use should be encouraged, provided the}- elucidate a point 

 or points and can be employed to as good or better advantage than their 

 equivalent in text. The large amount of copy submitted for publication 

 in connection with high printing rates has compelled most careful 

 scrutiny of illustrations in order to secure the best results. There is no 

 question but that an illustration in a scientific publication should tell 

 a real stor}\ It should do it as well and preferably better than text 

 and applying the test of recent years in regard to printed matter, it 

 should tell a hitherto unrecorded tale. The mere fact that an illustration 

 represents a condition or process not heretofore known or described 

 for one part of the country does not justify the expense of reproduction in 

 a publication having a world wide circulation, though it could undoubt- 

 edly be used to excellent advantage in locally distributed literature. 



Occasionalh' a considerable series of most excellent photographs 

 are submitted. Limited resources make reductions imperative and in 

 some cases most of the points can be clearly established by using only a 

 portion of the series. Sometimes, an attempt is made to include too 

 much on a plate. A few well engraved figures showing what is desirable 

 are better than a larger number reduced so greatly as to obscure essential 

 features. It is suggested that authors, with the above in mind study 

 critically their illustrative material before submitting it for publication.
