Excerpt from An Experimental Investigation Into the Flow of Marble, 1901 In the present paper* a first contribution to such a study is presented, pure Carrara marble being the rock selected. At the outset the endeavour was made to submit this rock to the first of the three conditions above mentioned only - that is, to bring to bear upon it great pressure from all sides, a pressure, however, which should not be equally great in every direction, but which, while always exceeding the elastic limit of the rock, should be greater in one direction than in others, thus tending not merely to bring about cubic compression but to determine a flow of the material in one direction. For this purpose it was sought to enclose the marble in some material having a much higher elastic limit than the rock itself, and possessing at the same time a very considerable ductility, so that it would move without rupture when the pressure became sufficiently high. Under such conditions it was believed the marble could not break in the ordinary way, even when submitted to a pressure far above that which under ordinary conditions would be required to crush it, for it would be enclosed on all sides by a stronger substance, and the pressure being increased it would remain intact until the elastic limit of the enclosing material had been exceeded, when it would commence to move, acting as water or any other enclosed fluid might.
