In this work the seed has always been treated for the preven- 

 tion of scab, the crop has received liberal fertilizer and careful 

 attention, particularly to spraj'ing and cultivation. The seed 

 has been carefully selected and stored each year. By growing 

 the different varieties for four years, and each year discarding 

 the poorer ones, we have several very good varieties left. 



It is hoped another year to begin an attempt to ito prove 

 some of the varieties by the tuber unit and hill selection 

 method, and to determine, if possible, how long certain varieties 

 when selected in this way may be grovvn in this locality before 

 "running out."
