Briggs. --This method of obtaining a supply seems to be coming into general notice. In my opinion its success depends entirely upon the locality. This section of country (Terre Haute, Ind. , ) for miles has a splendid bed of water-bearing gravel underlying it at a depth from the surface of from twentyfive to forty feet, about on a level with the bed of the Wabash river. It appears to me that the point in Query 51 in regard to air getting into suction pipes is not necessary to be discussed.
