DIVISION OF SOILS 



In this division Prof. M. J. Funchess has secured results 

 from his laboratory and field experiments that promise great 

 practical as well as scientific value. 



A continuation of the experiments to determine the lasting 

 effect of certain organic toxins indicates that most compounds 

 lose their toxicity after being in contact with soil for a time. 



At this date, there is no indication of a toxic effect of vanillin, 

 cumarin, or quinoline added in July, 1917, to the soil from the 

 Arlington farm. 



The work on the development of soluble manganese in acid 

 soils is yielding very interesting results. It has been very 

 clearly shown that nitrification of dried blood may bring into 

 solution relatively large amounts of manganese. Further, it
