Common barberry (Bcrbcris vulgaris) was not often 

 seen about the dooryards. All that I found occurred as single 

 clumps and in one hedge. Every specimen was badly infected 

 with the black stem rust of wheat {Puccinia graminis). The

 found at any one place. 



Privet {Ligiistruin vulgarc) is infrequent and when 

 found it occurs as a hedge. It grows fairly well and when
