These varieties and strains were tested by sowing a number of pots of 
each, about 10 kernels being sown to a pot. When the seedlings were in 
about the second or third leaf, they were inoculated with a culture of 
leaf rust obtained from volunteer rye at La Fayette, Ind., and maintained 
in the greenhouse as stock material. Infection appeared in from 7 to 
10 days and when the rust had reached its maximum development, 
usually about 2 weeks after inoculation, notes were taken. Table II
