experiments show that symbiosis between certain bacteria and plants 

 requires further investigation before the full scope of its practical appli- 

 cations, purposive inoculations of soils on an agricultural scale, can be 

 realized. Further, the author has experimented with artificial soils in 

 which the proportions of calcium salts, nitrates, phosphates, and other 

 ingredients were varied, and comes to the conclusion that, for agri- 

 cultural purposes, the chemical composition of the soil is quite as 

 important as the nature of its bacterial flora.
