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
