April, '13] WEBSTER: LOGICAL BULLETIN ARRANGEMENT 183 



unless it be the words larva, pupa or adult, and the meaning of these 

 the average reader ought to know. I think it is best to explain these 

 common terms the first time they are used in the text, afterward using 

 them without further explanation. If a popular edition of the bulletin 

 is to be issued, the first part of the regular edition, including the dis- 

 cussion of the control measures, may be printed as a separate bulletin. 



Having concluded that part relating to the measures for control, we 

 are now ready for the more technical treatment, such as the past his- 

 tory, the synonymy, the stages in detail and the natural enemies of 

 the insect. In this part of the bulletin we are writing more for ento- 

 mologists; few others will pay very much attention to the technical 

 portion. Order is less important here, since the entomologist will look 

 for those things in which he is interested, and on account of his training 

 he is able to pick out more easily the essential points. But we must 

 have some order, and the chronological order such as indicated ap- 

 pears to serve as well as any other. The position for the bibliography 

 is, of course, at the end. 



Summaries are frequently placed at the end of a bulletin; a rather 

 natural position. Personally, however, I like to see them at the front, 

 where they may be encountered as soon as a bulletin is opened, and 

 boiled down to a single page, giving the real essentials of the bulletin. 



Such an arrangement of material as has been here indicated the 

 writer has been using in entomological bulletins of the Iowa Experi- 

 ment Station during the past four years and it has proved to be very 

 satisfactory. 



In order to bring out the arrangement here considered a little more 

 clearly, there is given below an outline on which a bulletin of this kind 

 may be built up. This refers to a monographic bulletin, concerning 

 one insect.

3.' Appearance of the injury. 



4. The insect's appearance (brief descriptions) 



5. Time of appearance of the generations (briefly).

7. Steps advised. 



8. Past history. 



9. Destructiveness. 



10. Distribution. 



11. Food plants. 



12. Classification. 



13. Life history.
