Some work has been done on a general index to the eleven volumes 

 of the Record thus far published and Bulletin Ko. 2 of this Office, 

 which is essentially another volume of the same character, being a 

 digest of the reports of the stations for 1888. Such an index has 

 become a labor-saving necessity in connection with the Avork of this 

 Office, and it is hoped that on its completion it may be found practi- 

 cable to print it for the use of the readers of the Record. 



MISCELLANEOUS PUBLICATIONS. 



The miscellaneous publications of the Office consist chiefly of (1) 

 technical bulletins and reports and (2) farmers' bulletins, including 

 the series known as Experiment Station Work, and are prepared 

 under the immediate editorial supervision of Mr. AV. H. Beal. 



TECHNICAL BULLETINS. 



Farmers' Reading Courses (Bulletin No. 72, pp. 36), prepared by 

 L. H. Bailey, professor of horticulture, Cornell University. This 

 bulletin shows the scope and methods of work followed in farmers' 

 reading courses in the United States, which, "as an important jjliase 

 of the general movement among our agricultural colleges to go out- 

 side of their class rooms and promote the education of our farmers 

 along the lines of their art are now attracting widespread attention." 

 It reviews their history and present status, describing reading courses 

 actually in operation in seven States, and contains suggestions regard- 

 ing the organization of such courses, witli an ai)pendix, showing rep- 

 resentative documents used in the courses in various States.
