Unfortunately the journal referred to in Ir.

Duncan's report, descriptive of the strata passed through

by the borings and prickings, has not yet amme to hand,

we are only able to form an opinion of the material by

inspection of the samples. These, of course, represent the

material after being broken and churned up by the bering

teels and are, therefore, incomplete without the description

20companying them.

Nevertheless from an examination of the samples

taken, in conjunction with the recorded penetration of the

pricker used in taking the prickings, it appears to us that

the material below the line marked "hard as derived fre

borings", should prove satisfactory for the foundations of

of this "hard" drope to a depth too great to admit of the

foundations being carried right down therete, we consider

that a satisfactory foundation sould be obtained by means of

a rubble mound deposited in a trench dredged some few feat

below the line marked "hard se derived from prickings”.

Before preparing contrast drawings for carrying out the work

it would be advisable to take some further borings along

the sxaet lines of the works as decided upon.

As already mentioned, the tidal currente as

derived from the numerous observations taken, are of very

moderate strength and should net, in our opinion, cause any

difficulty in bringing vessels alongside the quays.
