surface of the soil of those to be inoculated. Sterilized sphagnum was 

 then placed over the soil to the depth of an inch, and covers were tied 

 over the tops of the pots. After three days some of the pots were placed 

 outdoors, being set in the soil so that the tops were level with the surface 

 of the ground; others were left inside the violet house, where the tempera- 

 ture is kept cool. Check pots not inoculated were similarly prepared. 

 At each planting made thereafter a control pot, made up of fresh uncon- 

 taminated soil, was inoculated in the same manner as were the pots in- 

 oculated earlier. Twenty-five clean beans of the variety Refugee Wax 

 were planted in each pot except in the first planting, when the variety 

 Extra Early Refugee was used. After planting, the pots were kept in the 

 warm house. The results are given in table 4.
