diagram (fig. 2) in a suitable scale. The lower curve represents the vertical 
displacement and the upper one the slope of the ground. The course of the curves is 
very similar to that of fig. 1, as we would expect, except at the points very near to 
the edge of the loaded area, where, as there is no discontinuity in the load in this 
case, the slope remains finite.

Let us take an example, with the same assumption regarding the various constants 
and the position of the point of observation as in the former example, and suppose 
that the total amount of the load is the same as before, i.e., the mean height of the 
tide is one metre. Then we shall have 
xfr = U12x HU 8 = 0 // '0023, 
0 - 3'21 x KG 8 = 0"’0066, 
and 
^ + 0 = 4-33 x ICG 8 = O^’OOD, 
nearly the same as the result in the former example.
