During the last ten years the Pacific fleet of the United States Navy has occasionally engaged in target practice off the coast of southern California. The sound of this gunfire has often been heard tar inland, especially at night and in the winter season as in Europe on the continent. The distance between the source and the points of observation was often so great that abnormal audibility is clearly indicated.
