BOARD OF AGRICULTURE. 



in addition to those of the county societies, fifteen experiments 

 were commenced. One has been relinquished, and fourteen 

 have been carried through the three years' course to completion. 

 It is proper for us here to express our especial obligations to 

 P. C. Brooks, Jr.,Esq.,the.obliging Secretary of the Massachu- 

 setts Society for Promoting Agriculture, for his kindness in 

 placing in our hands the returns of these experiments as 

 received from the competitors, otherwise through the negligence 

 of the secretaries of some of the agricultural societies who 

 failed to return copies to the Secretary of the Board of 

 Agriculture, we should have been deprived of them entirely. 

 A condensed summary of each experiment is here given for 

 future reference and comparison.
