were but slightly injured. However, severe injury occurred between the 
temperatures of n° and 23 °. Growing-point destruction resulted only 
at 15°, i8°, and 21 0 . 
Experiment 2.—In, Experiment 2 plants were grown at the various 
temperatures in unsterilized soil inoculated with the same strain of Corti¬ 
cium, vagum as that used in Experiment 1. These were checked by a 
similar number of plants grown in uninoculated soil. Except for the 
increased number of seeds planted in each pot, Experiment 2 was practi¬ 
cally a duplicate of Experiment 1. Twelve seeds were planted in each 
pot in both the inoculated and uninoculated soil. The results were as 
shown in Table III*
