EXPERIMENT 2 



The Influence of Subsoil on the Distribution of Capillary 

 Water in the Overlying Soil 



Conduct the experiment in every particular as in Ex- 

 periment 1, already explained, except that in paragraph 4 

 of directions, the cylinder be placed .on the surface of a 

 bucket full of dry sand of the same kind and grade as that 

 used in the cylinder. 



EXPERIMENT 3 



The Influence of a Heavy Subsoil on the Distribution 

 of Capillary Water in the Overlying Soil 



Conduct the experiment in every particular as in Ex- 

 periment 1, except that in paragraph 4 of directions, the 

 cylinder be placed upon heavy clay. (If the cylinder 

 can be placed upon bare ground, of a nature heavier than 

 the sand in the cylinder, preferably heavy clay, the same 

 or similar results should be obtained. In this case the 

 filter paper may be dispensed with.) 



EXPERIMENT 4 



The Influence of a Layer of Gravel or Coarse Material on 

 the Distribution of Capillary Water in the Overlying Soil 



Conduct the experiment in every particular as in 

 Experiment 1, except that the fourth section from the 

 bottom be filled with very fine gravel, or very coarse 

 sand, and that the gravel or sand be moistened before it is 

 introduced. In this experiment, the lower four sections
