274 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 2 



which vitally interests the farmer. Concise discussions of experi- 

 ments performed may well find a place under this head, but the 

 average reader will be satisfied with a well summarized discussion of 

 these results and with the conclusions drawn from them fully as well 

 as if all the data upon which they are based be submitted, for he will 

 accept the judgement of the writer and will rarely study all the 

 details. It is of course important that due prominence be given to 

 these experiments as they show the experimental work done by the 

 writer. 



Under Means of Control a definite distinction should be made by 

 headings between those which are preventive and those which are 

 remedial. More and more we are laying emphasis on preventive 

 measures and we should aid the reader to distinguish between pre- 

 vention and remedy. Under both of these heads, sub-headings should 

 indicate clearly against what stage of the insect the preventive or 

 remedy is effective and the action of the preventive or remedy should 

 be clearly explained. Definite descriptions of the use of the preven- 

 tive or remedy should be given so that it may be followed easily by 

 the reader untutored in such matters. 



The bulletin may well close with a few references to the more im- 

 portant publications available which might be consulted by those 

 who wish further information upon the subject in hand, but the long 

 bibliography is of no value to the average reader. With the short 

 bulletin, if it is well summarized, no index is usually necessary pro- 

 viding the different parts have been well indicated with proper type. 



Spray Calendar. — A publication which has always been popular 

 has been the spray calendar. It is a sort of farmer's encyclopedia of 

 practical entomology and plant pathology and is one which will 

 constantly be open to improvement. It is a question whether the 

 original style of calendar form is the most desirable and we have 

 noticed that many of the stations are now issuing Directions for the 

 Treatment of Insect Pests and Plant Diseases, rather than a spray 

 calendar. The idea that a definite calendar can be issued by which 

 the agriculturist can fight his pests according to some rule, is an ex- 

 ceedingly enticing one but one which hardly tends to encourage him to 

 secure that understanding of a pest which is necessary for its intelli- 

 gent and successful control. It is the writer's belief that the form 

 of publications now being issued by Cornell, Geneva and other stations, 

 giving concise descriptions of the pests arranged under the crops that 

 they attack, with brief suggestions for remedies, and then a descrip- 

 tion of the various insecticides and other means of insecticidal con- 

 trol, is much better than the calendar form.
