No. 4.] NITROGEN AND FERTILITY. 165 



ings the past two days have been so successful, not only in 

 quality of addresses but in the numbers we have had and in 

 the interest that has been taken. I feel very well pleased 

 that the invitation was accepted, and that the Board decided 

 to hold these meetino-s here in Worcester instead of in sonic 

 other place. 



The question which we have to discuss this forenoon is 

 certainly an interesting one, and I have the pleasure of 

 introducing to you Dr. Chas. D. Woods, director of the 

 Maine Agricultural Experiment Station, who will speak on 

 the subject of " Nitrogen in relation to soil fertility."
