Where much material has to be handled one shoveler 13 Relics of the Revolution can keep two sifters busy, each taking turn to sift and shovel atshort intervals. An etiective addition to the means of exploration is the sound-ing rod or probe, which was devised by Mr. Calver, a slender andpointed steel rod set into a wooden handle, which can be presseddown into the soil, to locate obstmctions and objects bidden belowthe surface. Practice makes perfwt. and the constant use of this. Explorers and Visitors implement affords the user almost as valuable service as an eyethat could see below the sod. An object such as a stone can bedetermined by prodding its hard surface, and its size can be definedby piercing the soil around it. The feeling of an oyster shellis quite distinct, as it can be pierced by a sudden thrust, while ahuman bone is quite distinctive to the sense of feeling ou therod. and a tree root has as characteristic a feel a bone or 14 The Search for Relics a piece of metal. ^Mien a bard floor has been traced by the rod,the work of exploration consists in removing the top soil and heavymaterial down to a point just above the floor line, which is indi-cated by judgment.
