EXPERIMENT STATION RECORD. 



Vol. XX. June, 1909. No. 12. 



With the present number the abstract portion of the twentieth vol- 

 ume of Experiment Station Record is brought to a close. This por- 

 tion of the vohime contains 1,200 pages, of which 1,054 are devoted 

 to abstracts, 7G to editorials and special articles, and the remainder 

 to station and miscellaneous notes. The customary author and sub- 

 ject indexes will be issued separately somewhat later. 



The number of abstracts in the volume is 5,33G, which is by far 

 larger than in any previous volume, and nearly 700 in excess of the 

 number in Volume XIX. It is estimated that the preparation of 

 this material involved the review of 40 reports of the American ex- 

 periment stations, 398 station bulletins and circulars, and 232 publi- 

 cations of this Department, together Avith the examination of fully 

 20,000 copies of other publications, including periodicals, books, etc., 

 appearing in twelve or more different languages. 



The distribution of the abstracts by subjects was as follows : Agri- 

 cultural chemistry, 469; meteorology — water, 193; soils — fertilizers, 

 66G ; agricultural botany, 176 ; field crops, 306 ; horticulture, 223 ; for- 

 estrj'^, 222; plant diseases, 259; economic zoology — entomology, 542; 

 foods — human nutrition, 559; animal production, 383; dairy farm- 

 ing — dairying — agrotechny, 304; veterinary medicine, 475; rural en- 

 gineering, 97 ; rural economics, 197 ; agricultural education, 169 ; and 

 miscellaneous, 96. 



The twenty volumes of the Record thus far issued contain about 

 71,650 titles, besides editorials, special articles, and notes. The sta- 

 tion reports abstracted have numbered 868, the station bulletins and 

 circulars 6,912, and the publications of this Department 3,055. 



It is of interest to note that of the total number of abstracts about 

 36,400, or somewhat more than one-half, have appeared in the eight 

 volumes issued since the publication of the first general index. It 

 is hoped to cover this period by a general index to Volumes XIII-XX 

 in the near future.
