Paper submitted to controvert popular idea that if building or other property in neighborhood of coal mine shows signs of dilapidation, mine should be blamed and expense must be put on mine proprietors; observations during period of years lead author to believe that in working of deep seams there is usually no fracture that reaches surface, but only gradual and slight lowering of surface; it is recommended that managers and surveyors take observations and levels on surface before working coal seams. Paper read before Inst. Mine Surveyors.
