not clear and where the slumping of incoherent beds from river- 
terrace 1s reasonably certain to have occurred. А local difference in level k 
of the bed of large boulders just referred to may be attributed to river- 1 
scour when the bed was being laid down; it is also slightly off the line of 
the depression, which makes a turn of about 10? at its upper end, and as a 
result no clear exposure on its line occurs. The possibility of any supposed 
of the deformation is oriented in a N.W.-S.E. direction, parallel to the 
general direction of the “ Railroad." ; 
It is thus possible that the movements may have continued down to 
à very late geological time. "There are definite occurrences of recent dis- 
location on this line—e.g., that recorded from the Waipara Valley by 
Speight and Wild (Trans. N.Z. Inst., vol. 50, pp. 76-77, 19

from the up-stream river-bed, and depositing a proportion of it on the 
margins where the force of the wind was less and friction greater; and the -
