1. We are fully convinced, after making these observations, 
that there is a connection between the common barberry and the 
black stem wheat rust. On the south side of this ruined field is 
a large planting of common barberry bushes, which have been 
badly infested by the rust. We have observed that the rust 
started on the side of the field next to these bushes and that 
now the worst infestation is on the side nearest the barberries. 
2. We desire to go on record as favoring any legislation 
looking toward the complete eradication of the common barberry 
bush, believing it to be of no value, but on the other hand a 
serious menace to the wheat-growing industry.
