The editors will thankfully receive news items and other matter likely to be of interest to sub- 

 scribers. Papers will be published as far as possible, in the order of reception. All extended con- 

 tributions, at least, should be in the hands of the editor the first of the month preceeding publication. 

 Contributors are requested to supply electrotypes for the larger illustrations as far as possible. Photo- 

 engravings may be obtained by authors at cost. The receipt of all papers will be acknowledged. — Eds.

It is perhaps unnecessary to state that the appearance of

 The August number is now in press and may be mailed

The Insect Pest Survey recommended by the association at its last 

 meeting is an accomplished fact and the first two issues of the monthly 

 Bulletin and a number of special Reports give a more definite idea of 

 possibilities than could be obtained from any general discussion of 

 plans. The survey organization affords a ready means of picturing 

 the seasonal developments of the country and as a whole it will be of 

 value in proportion to the cooperation it receives. 



It has started excellently and it remains for those who advocated 

 the departure to give such support that there can be no question as to 

 the merits of the undertaking. Insect life recognizes no political boimd- 

 aries and is very subject to local and more or less irregular, frequently 

 poorly understood fluctuations. One problem of the survey is to ac- 

 cumulate all such data and as general tendencies become better known, 

 the probabilities of utilizing them in practical ways are greatly increased. 

 The survey may be characterized as a nation-wide attempt to cooper- 

 ate along scientific lines. It can succeed only through mutual service. 

 The men in the field must provide data, — there can hardly be too much. 

 Those in charge must see that the information is promptly distributed 

 in a convenient form. As a consequence of organizing this stu-vey, 

 every man's work will have a perspective not heretofore possible in 

 many instances. There are also great possibilities in the proposed 

 annual digest and later, as data accumtdate, in the recognition of dis- 

 tinct tendencies in various sections. The successful control of insect
