may be easily obtained, the possibility of obtaining water 
from deep wells most not be overlooked. The following 
table gives data concerning the quality of water found in 
deep wells penetrating the same strata from which a supply 
at Indianola would be obtained:

From this table it is far from certain that an acceptable 
quality of water would be secured from a deep well. To 
reach the deepest strata from which water is obtained in 
the above mentioned wells (the Saint Peter and Saint Croix 
sandstones) the well at Indianola would have to reach a 
depth of 1800-2200 feet. The receipts, which are at 
present only about $2,500 per year, will not. warrant 
expenditure on such an uncertainty. 
If the necessary quantity and quality of water alone 
were to be considered the place where the pumping station 
ought to have been located is just north of Middle river, 
six miles north of Indianola, on a strip of second bottom 
land which extends southward to near the river. Here, at 
a depth of only twenty-five feet below the second bottom, 
the sands contain an inexhaustible supply free from iron. 
The drainage area up the river from this place is about 
four hundred and eighty square miles. Should the river 
itself go dry, as it did in 1895, the sand below the bed of 
the river could be relied upon to furnish a supply during 
the drought. At this point the pumping station would be 
within half a mile of a railroad on a level bottom land 
over which a branch road oould be easily laid, and near 
coal mines from which coal could also be hauled in
