Underground waters of southwestern Kansas . h it. Or it is possible for a mass ofsand to be entirety surrounded by an impervious clay, so that a drillpenetrating the sand will receive no flow because there is no pressureon the water the sand contains.

The experience with wells whichare of little value for weeks, or even months, after which time theybecome strong flowing wells, shows that in some way they becomechoked with sand, permitting only a mild flow until the sand isremoved by pumping or otherwise. It seems that the northern and western sides of the valley are themore productive. At present the best wells are in the northwesternportion of the valley, but flowing wells have been obtained all theway from Wilburn, on the northeast, to Meade, or possibly a mile ortwo south of Meade, to the southwest. The flow of the wells variesfrom a pailful in five minutes to 45 gallons per minute.

The water obtained from the wells is largely used for irrigationpurposes. Many of the wells were simply left flowing, and the waterallowed to waste, without any attempt to use it.
