Beans Grown in Soil with and without N. OC. “ Floats.” 
Two pots were filled with garden soil, and to one was added 75 
grams of unacidulated ground phosphate rock. In each were grown 
two beans (yellow eyes), until they were just passing out of bloom, 
when they were examined. Below are tabulated the results :

Water was supplied to each pot as needed by the growing plants. 
It is a singular coincidence that the beans, as harvested from the 
two pots, should weigh the same. 
Further experiments are needed before making any generaliza- 
_tions, and discussion of results is reserved until other’ experiments 
are completed.
