198 DEPARTMENTAL REPORTS. 



detailed index, as a means of looking np work which has been done 

 on a i)articular snbject, increases with eacli volume issued. The 

 combined index, which is in preparation, will furnish a full subject 

 index to experiment station work since the passage of the Hatch Act, 

 and to a very large proportion of the contemporaneous investigation 

 along lines related to agriculture. 



Tlie demand for the Record has necessitated a small increase in the 

 edition during the year. Its circulation is, as before, confined to 

 such persons as are engaged in agricultural research or instruction, 

 under a fairly broad interpretation. The foreign list is sent largely 

 in exchange at present and results in an increasing amount of period- 

 ical literature, experiment station reports, separates, and scientific 

 papers which materially assist in following up the foreign literature 

 of agricultural science. 



The review of the literature of agricultural science in the Record is 

 made more complete and comprehensive year by year, and the devel- 

 opment of various agencies for agricultural investigation adds con- 

 stantly to tlie material to be reviewed. During the past year no less 

 than 1,500 scientific journals, periodicals, and serials have been fol- 

 lowed up systematically, some of these being weeklies. In addition 

 to these a very large number of reports of municipal. State, and Gov- 

 ernment experts, commissions, and boards from all over the world 

 have been reviewed. That the great amount of labor involved in the 

 issuing of the Record is not misdirected is evidenced by the place 

 which it has taken among abstract journals and by the use which is 

 being made of it by the nearly two thousand exi^eriment station inves- 

 tigators, agricultural instructors, and public officials who receive it. 

 Fewer leading articles were included in the last volume than in some 

 of the iH'evious volumes owing to a lack of available space. Several 

 valuable articles have been secured whose publication it was neces- 

 sary to i^ostpone. This pressure of material has made it necessary to 

 print the Record in a smaller type in order to gain space. Beginning 

 with Volume XIII brevier type has been used in place of long primer, 

 which will enable about one-third more material to be printed without 

 increasing the number of pages. 



The twelfth volume of the Experiment Station Record comprises 

 1,205 pages, and contains abstracts of 348 bulletins and 55 annual 

 reports of experiment stations in the United Slates and 158 publica- 

 tions of tlie Department of Agriculture. The total number of pages in 

 these publications is 31,208. The total number of articles abstracted 

 is 3,271, classified as follows: Chemistry, 172; botany, 158; fermenta- 

 tion and bacteriology, 38; zo'ology, 31; meteorology, 99; air, water, 

 and soils, 135; fertilizers, 139; field crops, 353; horticulture, 320; for- 

 estry, 130; seeds and weeds, 80; diseases of plants, 248; entomology, 

 334; foods and animal production, 314; dairy farming and dairying, 

 181; veterinary science, 347; technology, 25; agricultural engineer- 

 ing, 56; statistics and miscellaneous, 121. 



Special articles were also published in this volume of the Record as 

 follows : ' ' Notes on horse feeding," by E. Lavalard ; ' ' New agricultural 

 building at Kansas State Agricultural College;" "International con- 

 gresses of horticulture, viticulture, and agriculture at Paris," by 

 W. H. Evans; "New buildiug for the College of Agriculture at the 

 University of Illiuois," aud "Russian soil investigations."
