A device is described consisting essentially of a pressure tank, an air pump, and a pressure gage, together with pipes, valves and fittings by which a dye solution is forced into the crack to be explored. Then by drilling, the crack is followed inward until it is bottomed. The depth of the crack is established by a pressure test. Some results obtained using the device are reported.
