description	129,621. Lundberg, H. T. F., and Nathorst, H. J. H. July 8, 1918, [Convention date]. Locating conductors.-A vein of ore or mineral, shown by the shaded area, is located by tracing the equipotential lines due to current, preferably alternating, flowing through the earth between two long electrodes A', A , which may be straight ropes or wires. The curves are traced by searching-rods connected to a galvanometer, telephone receiver, &c.
