and each photograph and drawing should boar a number corresponding to that in 
dist just mentioned, and its proper legend. The author should attend to 
his; if it is not done it entails unnecessary work for the editors and may 
se regrettable errors. Furnish only illustrations of the highest possible 
tity. The standard can not be set too high. A poor illustration often is 
Worse than none 2t 211, because it is misleading. A few first-class pictures 
owing the adult, egg, larva, and pupa stages, together with one showing the 
characteristic work of the insect, are worth double the number of poor illus- 
trations which are not to the point. Where photographs are to be made showing 
ersons engaged in remedial work or other activities it should be borne in mind 
tures and expression should indicate that they appreciate this. Where possible,

most desirabie. It may be in pencil, if necessary, as it can easily be put in 
printable shape in Washington. 
‘Subject Matter, 
_ Above all things, be brief. See your subject simply, outline it concisely. 
Use few technical terms--only those that are absolutely necessary--and explain 
the meaning of these as you proceed. Although it is not desirable to lay down 
any hard and fast rule on the subject, the matter in the bulletin should be ar- 
ranged about as follows: 
Table cf Contents:- The primary, or perhaps also the secondary, head- 
ings of the various sections of the bulletin only need be mentioned under *"con- 
tents." They should be arranged in double columns. 
Description of the Stage which is Most Injuricus:- Include no charace 
teristics which can not be seen by the unaided eye, and, as previously stated, 
avoid technical terms wherever possible. 
: Distribution:- Furnish a map where possible. Do not go into details 
here regarding particular outbreaks. Simply tell where the insect occurs, and 
in what character of country, when this is limited by topographical or soil 
conditions. 
; Economic Eee anoee A brief history of the more important outbreaks 
“may be included here, and it is also important to state, when possible, the actual 
‘loss, in money or in Sims of bushels, tons, etc., of the crop attacked. 
Manner of Injury:- This information may be given in a circumstantial 
‘manner, care being taken to avoid the inclusion of irrelevant matter. Do not 
‘mention names of investigators, or attempt to give credit, as this is not per- 
missible in a Farmers' Bulletin. 
Seasonal History:- State first whether the insect has a complete or 
incomplete metamorphosis. Couch this statement in simple words. Then outline 
the transformations in brief detail, stage by stage, afterwards going into the 
necessary details of each stage. 
Conditions Favorable to Outbreaks:- By the exercise of a little 
care, this statement can be rendered interesting and useful and it should, if 
‘possible, contain information which will allow the reader to be forewarned, of 
an outbreak. 
Natural Enemies:- Under this head the principal insect and vertebrate 
enemies may be described briefly, and illustrations of each form should be sup- 
plied when possible. It is not advisable, in the present state of our knowledge, 
to mention fungoid enemies of insects in popular publications. All evidence so
