Sir,

I.
Referring to your letter number 2347 of the 20th. inst.,
I have now obtained a great deal of the information required to
enable my Firm to deal with the matters upon which we were asked
to advise.
II. It will however be necessary for a considerable number
of borings to be made to enable us to deal with number (ii) item
in your letter, viz. "The provision of wharves and warehouses
provided with railway communication".
III. I have handed to your assistant Mr. Duncan a plan showing
the position of borings required at Hung Hom Bay, Tai Wan and
Pelcher Ridge. Each boring has a number or a letter. The former
borings should be completed first. If it then be ascertained that
a good foundation is fourd on a fairly uniform slope on the first
series of borings it will only be recessary to make a few check
borings of the second series. If on the other hand the first
series of borings reveals a good bottom at irregular levels it
will be necessary to complete the second series.
IV. Borings are of course expensive and take considerable
time and consequently it is of great importance that they should
be carried out under capable supervision and that the description
of the material met with at different levels should be accurately
recorded. All borings should be carried down to a depth of 50
feet below low water ordinary spring tides and if a good foundation
be not found at this level they should be contirued until a good
foundation is reached. Fy a good foundation I mean rock, gravel,
coarse sand or hard clay which will not disintegrate in water.
Samples of the differert materials passed through in the different
borings should be preserved in compartmert boxes and these boxes
