GREENHOUSE EXPERIMENTS 
The greenhouse studies on susceptibility of grain varieties to stripe 
rust were carried out in a wing of the greenhouse at the Oregon Agri¬ 
cultural Experiment Station, at Corvallis. The methods used were the 
same as previously outlined in the investigation of specialized races. 
The results of the inoculations made in the greenhouse during the 
three seasons, 1917-18, 1918-19, and 1919-20, using 92 different varieties 
and strains of wheat, are embodied in Table VIII. The method used 
in computing data has already been explained in connection with Tables 
III and IV.
