may be taken as an average of the side cuttings, for
one-third of the length of the line in the Buller valley,
below the Devil's Grip—(see fig. 2). It must be
observed that there are places where the cross sections
would be less favorable than is shown in figure, while
on the other hand there are many places where they
would be more favorable, so that on the whole the
sketch may be taken, excluding the retaining wall, as
a fair average, as far as my judgment goes. The pitched
facing to the embankment would be necessary in some
cases where the natural slope terminates close to the
edge of the river.

would be a great interruption to the trade at the
