next the water supply than the others and sand contained by far the 

 least. 



(21) Sand, with 7.77 per cent of moisture, gave up its moisture to 

 loam much more readily than did loam with 31.09 or clay with 24.62 per 

 cent of moisture. 



(22) The rate of rise of moisture from soils of varying fineness when 

 used either as water sources or water absorbers varied inversely with 

 the fineness. Water rose to a height of over 30 inches in a loam soil 

 from a moist sand in 94 days, while from a moist clay it rose little more 

 than 6 inches in this length of time. In all soils the most rapid rise of 

 the water was during the period soon after being placed in contact with 

 the water. 



(23) Although the rise of the moisture was more rapid in the sand 

 and loam than in the clay, the rise continued steady longer in the clay 

 than in the others.
