Many instances have occurred in South Lincolnshire where " faults" have been the cause of failure in obtaining water from wells and borings. They generally intercept the flow of the water, and in some cases their presence is shown by surface springs, due to this cause. As every well-section gives some additional information on the hydro-geology of a district, so it is of the greatest importance that the strata and results of such well or boring should be recorded intelligently and systematically. For want of this, much valuable information has been lost even in this limited area, and considering the fact that no boring can be undertaken with any confidence as to the result without the most careful study of the geological conditions of the particular district, this is especially to be regretted. With regard to the " hazel-twig" and other methods of divination the author's experience has been most unfortunate. Out of eight instances where he has had an opportunity of observing the results obtained by the "water-finder," six have proved ttotal failures. To return, however, to the consideration of "faults," it often happens that by this means pervious strata are brought into juxtaposition with impervious strata, as when Limestone is faulted against a Clay bed. In this condition, if the dip is towards the fault, an underground reservoir will be formed, but if the dip is away from the fault, it may cause a waterbearing bed such as the Limestone to be total...
