The periodical publications of the station have been as 

 frequent as in preceding years ; four bulletins, from ten to 

 eleven thousand copies each, and eight circulars of official 

 analyses, seven thousand copies each. The interest in these 

 pul)lications is steadily increasing on the part of farmers, 

 and the growing interest of the press is well illustrated by 

 our numerous exchanges of periodical publications from 

 home and a])road, as may be seen from a subsequent 

 statement. 



It gives me pleasure, before concluding, to express to you 

 my due appreciation of the faithful and sul)stantial su})})ort 

 I have received from all parties engaged with me in the 

 work accomplished at the station. With the assurance of 

 my sincere thanks for your kind encouragement and indul- 

 gence, permit me to sign, 



Yours very resi)ectfully, 



C. A. GOESSMANN, 



Director of the Massachusetts State Agricultural Experiment Station.
