The editors will thankfully receive news matter and other items likely to be of interest to our readers. 
Papers will be published as far as possible in the order of reception, except that papers of reasonable 
length may be accepted in the discretion of the editor for early publication, at $3.00 per page for all 
matter in excess of six printed pages; in the case of other matter, the maximum of 2,500 words is still 
operative. Photo-engravings may be obtained by authors at cost. 
Separates or reprints, if ordered, when the manuscript is forwarded or the proof returned, will be

Attention is called to some changes in reprint rates, see the usual

The abstracts appearing in this issue were prepared by the editor 
and have the approval of the various authors. This method was adopted 
simply that we might start on a general plan designed to make all 
biological literature more accessible. Authors are urged to prepare 
abstracts for future articles, it may be required later, even if the papers 
are in the editor’s hands at the present time. The abstract might 
well include or take the place of the summary and should be so written 
as to give a comprehensive and accurate idea of the contents of the 
paper. Prepare it in such a way that abstract journals can do no better 
than reprint it, and the indexer have no difficulty in locating the im¬ 
portant topics or subjects. Employ concise though complete sentences 
and distinguish clearly between compilations or digests and contribu¬ 
tions to knowledge. Do not overlook methods whenever they are of 
importance. Get all this within approximately five percent of the 
length of the paper. The editor welcomes criticisms or suggestions in 
relation to this departure. He regrets that it may be impossible to 
please all. 
One of the items of business at the recent meeting of the Associa¬ 
tion was the reading of an invitation to an “International Conference of 
Phytopathology and Economic Entomology” to be held at Wageningen, 
Holland, next June (25th to 30th). 
It is good that such a conference has been called; and Wageningen 
will be an excellent meeting place, since it has been the headquarters of
