8 BULLETIN N. C. BOARD OF HEALTH. Remedy.—liore tlirough tlie obstruction without rtMnoving casing. This trouble comes on gradually and is usually found only in a loose stratum. 3. Decay of Cusiny,—This may cause waste of water by lateral leakage. Tlie usual life of pipe in an artesian well is very brief—rarely more than seven years. In many cases the ])ipe becomes perforated in two years. As a rule, the more highly mineralized the water is, the more ra])id will be the decay of the pipe. Trouble of this kind increases rapidly after st^irting. Remedy, renew casing. 4. Eochanstion of Supply.—The source of artesian water is the rainfall. In the eastern L'nited States the w^ater-bearing strata are feil by an abundant and fairly uniform rainfall. Exhaustion of the supply is therefore not likely to happen as regards any particular bed nnless carrying capacity of bed has l>een overworked. When exhaustion not due to waste really occurs, there is no remedy. Fig. 6.—a typical artesian basin. A. water-bearing, porous bed, B, dry, porous bed. E, outlet of dry bed. F, level of outcrop of A.

ANALYSES OF NORTH CAROLINA DEEP \YATERS. The following analyses of samples from North Carolina public water supplies derived from deep wells were made in the State Laboratory of Hy^aene during the months of Jaauary and February, 1907.
