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 $2.00 per page or plate. Additional hundreds or less, 4 pages

There is perhaps no phase of economic entomology requiring more dis¬ 
cretion in its administration than that relating to plant quarantines. 
The conference of Federal and State officials last April summarized in 
our issue for June 1, pages 431-433, formulated a program which leaves 
little to be desired in the way of a working agreement. Recent advices 
from the chairman of the conference informs us that all the States in 
the Union and in addition Porto Rico, Guam, Hawaii and British 
Columbia have now ratified the agreement. This is a notable step in the 
right direction and should be followed as soon as possible by such modi¬ 
fications in regulations and practices as to put it into full effect. Even 
then there will be a multiplicity of nice points requiring decision from 
time to time. 
The report of the Rockefeller Foundation for 1923 contains an ac¬ 
count of the attempt to eradicate yellow fever from Brazil and records 
an absence of cases from Mexico, Central America, Ecuador and Peru. 
It suggests the ultimate eradication of this scourge from the entire 
world. The report also discusses the malarial control work started in 
1916, special attention being given to rural areas. Last year special 
malarial investigations were carried on in the United States, Brazil, 
Nicarauga, Palestine, Philippine Islands, Salvador and Porto Rico. 
The work of the Foundation, world wide in scope, affords additional 
proof that under ordinary conditions many communities can reduce 
malaria to an almost negligible point and at a per capita cost within the 
limits of local taxation. These great benefits to humanity are striking 
illustrations of applied or economic entomology, since the control of
