Bulletin . or long distances, but in a few instances a single vein maybe traced either .by the outcrop or continuous quartz debris for distancesvarying from one to two miles, and in one case the so-called Mother Lodevein was traced by outcrop or almost continuous quartz debris for nearlythree and one-half miles. All veins of the district have characteristicpeculiarities, such as pinches and swells both linearly and vertically,which tend to give them the appearance of numerous connected quartzlenses. In fact, in many instances the lenses are disconnected, and in othersthey are joined together only by a mere stringer of quartz. In other casesthe fractures are apparently continuous for longer distances than the veinsshow them to be. In such eases vein matter has been developed only atirregular intervals in the fissures. These peculiarities have a practicalapplication in doing development work, in that even though the vein pinchesto very narrow limits, or is lost altogether, the fracture in which it.
