Substation at Mitchell, Neb. and drying up of leaves that the typical wilting phenomena were scarcely realized. The vascular bundles were blackened and the blackening extended even into the petiole and the leaf veins. This rapid killing was at first strictly localized on that side of the plant t which the inoculum had been applied, even in the leaf, where the leaflets on one side of the midrib would he affected, and those on the other side not.
