N2  - In connection with studies on corn rust (Puccinia sorghi Schw.) conducted at the University of Wisconsin during the year 1919-1920, data were obtained particilarly on: (1) the relation of temperature to germination of urediniospores; (2) the relation of temperature of infection by urediniospores; (3) mode of host penetration in uredinial infection; (4) overwintering of urediniospores; (5) relative susceptibility of corn apecies. Corn seedlings were grown in the greenhouse in eight-inch pots and in flats six inches deep. Urediniospores were obtained from infected plants in the greenhouse, excep when otherwise stated. Inoculations were made by rubbing the corn leaves with a scalpel or platinum loop. All inoculated plants were incubated in a moist chamber for thirty-six hours immediately following inoculation. In the course of the studies it was noted that when urediniospores were shaken from pustules their percentage of germination was higher than when the spores of the same as follows: A droplet of water was squeezed from the drooper and gently stroked over the top of the pustule, the mature spores were picked up readily by the surface pf the drop
