Influence of Soil Temperature on Fusarium in Cabbage 79 
After the soil moisture had become constant, seed of the Commercial 
Hollander strain was planted in the usual manner, and the final data were 
recorded 28 days later. A few days after the plants emerged from the 
soil, they were thinned to the desired stand and a half-inch layer of mineral 
wool was placed over the surface of the soil to equalize surface tempera¬ 
tures. In Table XII the average results from the duplicate receptacles 
are shown separately for each experiment at the end of different periods 
of time. The average results of the two experiments are given in Table 
XIII and shown graphically in figures 9 and 10.
