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 
supplied to authors at the rates given below. Note that the number of pages in a reprint may be 
affected somewhat by the make-up, and that part of a page is charged as a full page. Carriage charges 
extra in all cases. Shipment by parcel post, express or freight as directed. 
One hundred separates or reprints at $2.50 per page or plate. Additional hundreds or less, 4 pages 
or less, $1.00; 5-8 pages, $1.50; 9-12 pages, ’1.75; 13-16 pages, $2.00; 17-24 pages $3.00; 25-32 pages, 
$4.00. Covers suitably printed on first page only, 100 copies, or less, $4.50; additional hundreds, or 
less, $1.75. Plates inserted, $1.75 per hunlred, or less. Folio reprints, the uncut folded pages (50 
only), sixteen page signature, or less, $3.00. 
The international conference on phytopathology and economic 
entomology in Holland last June was a notable gathering. It is a source 
of much gratification that our association was so ably represented and 
that we can reproduce in this issue a photograph of most of those in 
attendance. Such gatherings emphasize the essential unity of problems 
in the various countries and make possible more effective cooperation as 
a result of better understanding. The recognition of economic ento¬ 
mology as a science independent from phytopathology is in accord with 
American ideals and, in our estimation, fully justified by the facts, 
though it is recognized by all that there should be close cooperation 
between students in both branches. 
There are two phases of learning, the technical and the general. The 
former appeals to the investigator and is adopted to some extent, through 
necessity, in many commercial activities. Technicalities tend to break 
the solidarity of a community or group, and to that extent are undesir¬ 
able. On the other hand they make for greater precision. Specializ¬ 
ation in science has gone to such an extent that many in related groups 
know little of the activities of their associates and the general public 
even less. It is recognized that many technicalities are unavoidable if 
there is to be an extension of knowledge, and few would seriously question 
the wisdom of research. “Science Service” has been doing some notable 
work in popularizing science. The writer has been lead to suggest that 
investigators may help in this direction by avoiding unnecessary 
technicalities in their writings. Not many will read works requiring 
the constant use of a glossary. Is it fair to compel students in each 
group of natural science to acquire an extended special vocabularly,
