_The Dug Well._--A dug well is one of the older types of wells. It should be large enough in diameter to permit ingress and egress to all parts of it for repairs or for cleaning. Most dug wells require cleaning occasionally, due to the entrance of dirt at the top and to the washing in of clay and silt with the ground water. Many of these wells contain harmful gases which have proved fatal to those entering them. Before an attempt is made to clean such a well or to make any repairs, a lighted candle should be lowered into it. If the candle is extinguished, it will be dangerous to enter until the well has been thoroughly ventilated. A dug well will vary in depth from 20 to 60 feet, depending upon the distance it is necessary to dig for an adequate supply of water. Types of pumping apparatus are on the market to cope with any depth in digging such a well. If dug wells are shallow, the water supply depends very largely upon current rainfall and in times of prolonged drouth there may be a serious shortage. Fairly deep wells of this type are usually very satisfactory and will supply surprisingly large amounts of water when the demand is made upon them.

The water from such wells is absolutely pure and it never fails. This is because subterranean streams have been tapped which are not subject to possible surface contamination, nor are they dependent upon showers for replenishment. Special power apparatus is necessary for constructing an artesian or drilled well. The drilling costs from $3 per foot up, depending upon the nature of the subsoil and whether rock is encountered. Unless such a well has been drilled in the immediate vicinity it is not possible to hazard even a guess as to when water will be struck. The consolation that such an undertaking has for the owner is in knowing there will be no doubt as to quantity or purity when the strike occurs. _Water Pumps._--Pumps are now available which operate automatically by electricity and constantly supply the home with fresh water drawn from the earth as needed. The requirements for the pump and the motor will vary with the depth of the well and the water requirements of the family. In all such cases, therefore, it is desirable to call in for consultation engineers or competent representatives of pump manufacturers or distributors. It should be borne in mind that adequacy of supply is most important and that economy in first cost, achieved at the sacrifice of an adequate supply, may be a definite handicap to necessary home services.
