Directions were given for the preparation of this medium 
obviating- the necessity of dializing, and making it possible 
to prepare this medium with greater certainty and greater 
accuracy. The use of the medium prepared in this way for 
f the culture of various organisms was illustrated by colonies 
of various bacteria growing in a thriving condition upon the 
medium.

17. The Efficiency of Soil Inoculation in the Production of 
Root Tubercles, F. U. Stevens, of the North Carolina 
Agricultural Experiment Station. 
Data was given concerning the inoculation of soils with 
liquid cultures obtained from the Department of Agriculture, 
Washington, D. C. From many tests conducted in various 
ways there was no evidence whatever that inoculation with 
these cultures was efficient in the production of tubercles 
upon the legumes. The cultures employed were issued in 
liquid condition in hermetically sealed test tubes, and were 
obtained directly from the Bureau of Plant Industry, Wash- 
ington, D. C.
