Barberry and Its Relation to Stem Rust. 6Y 
ated about two and a half miles northeast of Rushville. A careful 
search of the community resulted in locating a twelve-foot hedge of 
barberry bushes, most of which were over ten feet high. The infected 
fields were about three-quarters of a mile in direct line of the prevailing 
wind from the barberries. 
Case 10. Jefferson County. A barberry hedge and several group 
plantings were found, late in the fall, about one and a half miles north- 
east of Madison. When the relation of the barberry to the stem rust 
cf wheat was explained to one of the owners she recalled that a severe 
rust infection cccurred last summer in a wheat field across the road 
from the barberries. 
Case 11. Wabash County. Six infected barberries were found on 
the grounds of the Children’s and Orphans’ Home, three miles south of 
Wabash. Just across the fence from them was a wheat field in which 
the crop was badly rusted. (Reported by W. E. Leer.) 
Case 12. An old planting of six large and several small barberry 
bushes was found on a farm eight miles southwest of North Manchester. 
The older bushes were about fifteen feet high, with stems several inches 
in diameter. A considerable rust infection was observed in wheat fields 
in this community within a radius of nearly two miles, especially in 
the windward direction. A field of oats and another of rye, about a 
quarter of a mile from the barberries, were also heavily rusted. (Re- 
ported by W. E. Leer.) 
Case 13. Wabash County. A severe case of stem rust infection was 
reported by Nathan Gilbert on his farm five miles southwest of Wabash. 
Upon investigation it was found that numerous barberry bushes covered 
a hillside just across the road from the wheat field in question (see 
Fig. 2). The bushes showed abundant infection of the aecial stage of 
the rust. The entire wheat field was heavily infected, especially within 
a distance of about 100 feet of the road, where the grain was black 
with rust. Another wheat field situated about three-quarters of a mile 
from the barberries also had a considerable infection, but much less 
severe than the nearer field. The prospective yield of the first field 
was reduced by at least 60 per cent. A number of local farmers held 
a meeting at this field to see the havoc wrought by the barberries. 
The guilt of the bush was so firmly established in their minds that they 
went on record with the following resolution: 
We, the undersigned farmers of Wabash County, Indiana, at 
a meeting at the farm of Nathan Gilbert in Noble Township on 
July 19, 1918, called for the purpose of observing the ravages of 
the black stem wheat rust on the seventeen-acre wheat field, 
desire to go on record as follows:
