DIAGRAM OF THE WESTERN WHARF.
The diagram is portion of a sketch attached to the report by Messrs. Williams and Furkerl " showing tendency to deformation under stresses acting and results of such stresses." There is a note on the original that the deformation is exaggerated for clearness. The drawing represents a typical cross-section, illustrating the formation of the sea-bed after dredging into " benches," upon which, after the piles had been driven, a rubble mound was formed, with its top about 12 feet wide, its shape being shown in outline. On the top of this rubble mound is shown a gravity retaining wall of loose random rubble on the part now standing (concrete on the wrecked part). Between this wall and a similar wall 011 the top of the tide deflector, to the westward, was a space which had been partly filled to form a roadway; spoil was being tipped behind the outer end of the wharf when failure occurred.
