In a paper on Fossil Bacteria-Renault, illustrated by slides from the stereopticon, Professor Woodworth showed evidences of the existence of bacteria many ages ago, as is shown in fossils from...
...which the 3000 or more feet of dislocations were produced along this great fault line. It was thoroughly demonstrated that after a vertical movement of the rock for about 2000 feet, the irregularity of surface thus produced was almost obliterated through long wearing away by water. Then extensive lava flows were spread over the rock. At a later and relatively recent time movement on the fault line took place again so that the eastern part of these lava flows now stands 1000 feet above the western part, with a formidable cliff separating...
