and the intervening spaces be cut out so as to leave a perfectly white 

 margin between the different parts. The lettering of figures can 

 usually be done more neatly by the engraver's artist than by the ento- 

 mologist and may be readily indicated by pasting a loose sheet of thin 

 paper over the front of the plates and marking on it the lettering at 

 the exact point where it is wished. Plain plates are much to be pre- 

 ferred to the artistic scroll work and embellishments formerly em- 

 ploj^ed by some of our engravers. The plate should always be small 

 enough so that the legend may be placed immediately beneath it. A 

 plate put in the front of a bulletin with others scattered thru it and 

 then the legends tucked away on the last page are inconvenient for 

 the reader and probably very often the legends remain unread. 



For very many purposes line drawings are much to be preferred 

 to half-tones and it is to be regretted that we have become so infat- 

 uated with the ease of the photographic process that most of us de- 

 cline to take the time to make presentable drawings where we do not 

 have artists at our command. Undoubtedly a reaction in this matter 

 will soon occur. But even with the line drawings, if they cannot be 

 reasonably artistic they had better be omitted. The man who reads 

 the Station publications usually has some sense of the proprieties and 

 a crude drawing will hardly appeal to him as in keeping with the 

 reasonable dignity which should accompany the publications of a 

 scientist. 



Arrangement. — The arrangement of the bulletin should be logical 

 and with a natural sequence. A brief introduction pointing out 

 the general importance of the subject considered, followed by a 

 short historical sketch and a brief consideration of the extent of in- 

 jury due to the pest, may well occupy the first page or two. The 

 life history is generally the key to the methods of control and should 

 follow. The various stages of the insect should be distinctly but 

 briefly described and figured. In very many cases it will elucidate 

 the life history to the reader if the method and place of hibernation 

 be first described and the various stages and transformations of the 

 insect thru the season be followed thru the summer until it again 

 goes into hibernation. One of the things most difficult for the aver- 

 age man to understand is the number of generations and the trans- 

 formations of an insect and this should therefore be made as clear as 

 possible. The description of the various stages may well be placed 

 at their respective points in the discussion of the life history, rather 

 than being separated and the different stages described separately. 

 The different stages of the life cycle is often made clear by an illus- 

 tration such as has been frequently used by various entomologists
