not only how much and what the character of the drainage water 
but how much water is required to supply that column in 
droughty periods, from a constant water table at a given depth. 
If this method of supply and measurement of receipts and 
adits of water works well, then, in order to attain more 
nearly to the actual physical conditions of our soils there must 
be variation of this water table in harmony with that of the natural 
soil, or a considerable number of different depths must be studied 
to enable a fairly accurate generalization to be made as to subjects 
with which lysimetry deals. 
PREPARATION OF THE NEW LySIMETERS. 
The details of construction, placing, and the principle involved 
in working these lysimeters was given by one of the inventors.* 
The samples of soil taken at the time of filling the lysimeters 
were subjected to moisture determinations, and the following 
data, including the moisture determinations have been compiled 
from the records made by Mr. Goff.
