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.

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
