limit, dependent upon the suggestive value of the details and incidental 
matter. Critical judgment is essential regarding what is feasible, so far 
as the agencies for publication are concerned, and what is desirable, so 
far as the reader and the permanent value of the research are concerned. 
2. Occasionally the progress of an extensive research is considerable 
and the data available are important, yet the entire problem has not 
been completed. Under these circumstances an article which is a pre¬ 
liminary report of very extensive research and which announces some of 
the more important new features of the work may be published in the 
Journal and the completed work issued later. 
3. Each paper in the Journal is reprinted in a separate form. 
DISTRIBUTION OF THE JOURNAL 
The complete Journal is issued every week. It is distributed free 
throughout the world to agriculture colleges and experiment stations, 
universities, Government depositories, large technical schools, and insti¬ 
tutions whose work relates directly to scientific research in agriculture. 
No copies whatever are for free distribution to individuals. 
For those who desire to purchase the Journal, the Superintendent of 
Documents, Washington, D. C., maintains a subscription list, the price 
of the weekly magazine being $3 per year. Single copies may also be 
purchased at varying prices, generally 10 or 15 cents. The Monthly List 
of Publications of the Department gives the price of each number, as well 
as a list of the contents. 
DISTRIBUTION OF REPRINTS 
Each Department Bureau or State Experiment Station has entire con¬ 
trol over the distribution of the reprints emanating therefrom, with the 
exception of the following automatic distribution: 
(a) One hundred copies will be sent to the author or authors for 
personal distribution. 
(b) Reprints of State Experiment Station papers will be sent to 
Department workers interested in the subject of the paper. 
DEPARTMENT REPRINTS 
Any number of reprints up to 1,500, including the authors' copies, will 
be furnished to Department Bureaus. 
Every manuscript emanating from the Department should be accom¬ 
panied by a scheme (yellow card) giving in detail the distribution to be 
made of the reprints. If reprints are to be sent to any of the permanent 
stenciled lists of the Division of Publications or the Government Printing 
Office, either the key numbers or the titles of such lists should be given. 
In addition, Department offices should send to the Division of Publica¬ 
tions addressed franks sufficient for mailing the reprints to the addresses 
that are not upon stenciled lists.
