and the materials in them and the levels between which such
materials were found should be carefully labelled. It will be
better if the labelling of the different compartments be done by
writing with indelible pencil on the wood of the box and making
the box divisions wide enough for this purpose. Copies in a book
of the labelling of the boxes and compartments should be preserved.
It will be necessary to send us the journal and a diagram of each
boring and also a plan showing the position of each boring. A
certain number of the boxes containing samples of the borings
should also be sent to us. It will not be necessary to send all
the boxes provided these sent are typical and will, with the
description in the diagrams, enable us to form an opinion of all
material met with.

it would be advisable to take some additional current observations.
The observations recently taken were on the low tides as the high
tides occurred at night when float observations are not possible.
VI. In additions to the borings and current observations, I

sheltered deep water Harbour was probably the reason why very little
expenditure has been incurred in the past but the same reason
would, in my opinion, justify expenditure in keeping a record
of all changes and alterations. The large number of reclamations
completed, in progress or proposed will no doubt make their
influence felt in the future by causing some alterations and it is
important that a proper harbour survey on standard lines permanently
marked should be completed so that comparisons may be made from
time to time. I would like to suggest that the Staff of the
