Table I. — Showimj the Influence of Soil Decoctions u2)on Oermviation 

 of Seeds immersed for Six Hours in Decoctions made by licrcolating 

 500 G.c. of Water through 400 Grams of Soil; 800 Seeds used in 

 Each Treatment, except with the Soy Bean, where only 700 ivere 

 ■used, making a Total of 21 , 700 Seeds. 



The })rcccding table shf)ws the results obtained from ex- 

 periments in Avhich 21,700 seeds were emploj^ed. Since a 

 large number of seeds were used in these experiments, quite 

 accurate averages were obtained, and the factors due to 

 variation are eliminated to a large extent. There is appar- 

 ently a slight gain due to treatment shown in these experi- 

 ments. The best average results were given by the boiled 

 subsoil and loam, followed by the normal, while the sterilized 

 loam is below the tap water seeds. By noting carefully the 

 results obtained in these experiments, together with the 

 nature and color of the decoctions, we surmised that the de- 

 coctions were too strong for the best results, consequently 

 they were diluted with Avater to one-half strength in the next 

 experiment.
