It is the purpose of this paper to call attention to a rust epiphytotic in l 858, which apparently has been overlooked in the study of plant disease prevalence in Iowa. Early Iowa agricultural records and newspapers contain numerous reports of the calamitous wheat and oat failures caused by rust in 1858, yet this rust year has not been reported in any scientific publication from Iowa. Miss Hamilton2, who summarized material regarding a rust epiphytotic that occurred in 1878 in southern Minnesota, northern Iowa and Wisconsin, likewise makes no mention of the epiphytotic of 1858.
