PUBLICATIONS. 



During the fiscal year 1911 sixteen publications were issued by this 

 office. Among these, two Farmers' Bulletins were published, one 

 (No. 401) on "The General Use of Concrete on the Farm." and an- 

 other (No. 505) on "The Benefits of Improved Roads." Both of 

 these have been popular ])ubIications. The concrete bulletin was 

 widely distributed among cement manufacturers and farmei's, and it 

 is believed that it has been of great value to persons working on a 

 small scale because of the simple directions offered in it. Farmers' 

 Bulletin No. 505 supplies to a certain degree a long-felt want for a 

 publication telling of the (>cf)n()mic value of good roads. 



Nine bulletins of the office were issued, as follows: Bulletin 36, 

 Descriptive Catalogue of Road Model Exhibit: 37, The Examination 

 and Classification of Rocks for Road T)uilding; 38, Methcds fdi- the 

 Examination of Bituminous Road Material; 39, Highway Bridges 

 and Culverts; 40, The Road Material Resources of Minnesota: 41,
