EXPERIMENT STATION RECORD, 



Vol. VI. Ko. 1. 



With the beginning of the present volume of the Record the general 

 arrangement of the abstracts has been materially changed. The topical 

 arrangement, which heretofore has covered only the abstracts of station 

 publications and the list of titles of recent investigations, has now been 

 extended to the entire contents of the Record. Abstracts of station, 

 Department, and foreign investigations are grouped together by sub- 

 jects. Titles, reprints, and articles of less scientific interest are printed 

 in brevier type and arranged at the end of theresijecfcive topics, thereby 

 economizing considerable space. The list of the station publications 

 abstracted is continued in the table of contents of each number, so that 

 the account of the work of any station can be easily found. 



The change in arrangement is intended to make the Record more 

 convenient for reference and for general reading, to improve its general 

 appearance, to economize space, and to provide for further extension 

 of the subject matter. Abstracts and titles of articles on agricultural 

 science in American publi(;ations will be included. It is the imrj^ose 

 to make the review of the literature in the several lines as compre- 

 hensive as practicable, so that this publication may be a record of the 

 progress of agricultural science. 



Under the new arrangement the scientific divisions of the Depart- 

 ment will more definitely cooi)erate with this Office in the preparation 

 of the Record. 



The unpublished investigations of the late Prof. Gnstav Kiihn, for 

 twenty-five years director of the experiment station at Mockern, Ger- 

 many, have recently been compiled and published by his successor. Dr. 

 O. Kellner.^ These works cover a period of nearly twenty years, and 

 represent a large part of the life-work of this eminent investigator. A 

 list of Prof. Klihn's published works has already been given (E. S. R., 

 3, p. 837). The part now presented to the public is perhaps of even 

 greater scientific value. It had been withheld from publication until 

 results could be verified by further experiments or a series of investi- 

 gations completed. In this respect it presents a striking example of
