98 RELATIONS OF SOIL TO WATER 



Rep. 1892-3-4, 91) are especially instructive as the mechanical 

 analysis of the soils is also given. The experiments were 

 made in copper tubes i inch in diameter; the tubes were 

 in i ft. lengths, fitting into each other. One side of the 

 tube was glass so that the contents might be observed. 

 The bottom tube was closed at its lower end with muslin. 

 The tubes were filled with air-dried soil, stirred in the tube 

 with a wire, and made firm by a slight tapping on the table. 

 The composition of the soils, and the details of the rise 

 of water in them, are shown in Tables XV and XVI.
