lengths of piers, wharves,
or (in the case of enclosed
docks) dock quays, where
the maximum depth of to in water, referred Question 4, exists?
What percentage does the total of these lengthe bear to the total accommo- dation at the port ?
Bombay.
(a) The depth of 28 ft. (L.W.O.S.T) is found for a length of 3,000 ft. at the east wall and 770 ft. at the west wall of mole at the Alexandra Dotk
(8) The water aves of the Alex. andra Dock is 49-52 acres, and the length of quays 10,000 ft.
The total accommodation at the Fort amounts to 27,770 ft. of quay space for steamers.
The accommodation at the Alexandra Mole and Dock is about 50 per cent. of the total.

Calcutta.
The length of the jetty com-
pleted in 1914 is 585 ft. Total length of all jetties,
4,795 ft.
Total length of quay in docks,
10,216 ft.
There are also moorings in the
stream for 71 vessels.
6. What are the dimensions (length, loaded draught and beam at that draught) of the largest vessel which, under existing circum- stances, can be→
(a) berthed any pier
(L.W.OST)?
alongside
or wharf
(b) in the case of en- closed docks-
(1) admitted direct to or (2) admitted through
the entrance look of
any important dock or docks, H.W.O.N.T.?
There are no wharves or en-
closed docks.
The dimensions of the ships which can lie in the inner basin are only limited by the depth of water available. (See answer to question 4.)
(a) At the east harbour wall vessels of any length or beam could be berthed, but the draught is limited to 26 ft. 6 ine. (L.W.0.5.T.), allowing 1 ft. 6 ins. under the vessel's bottom.
(b) (1) Vessels of any length may be admitted to the Alexandra Dock with all | gates open. but at H.W.O.N.T. the beam is limited to 99 ft. and the draught to 32 ft. 9 ins.. allowing 1 ft. 6 ins. under the vessel's bottom.
The width of the entrance is
100 ft.
(2) If the vessels are locked in at H.W.O.N.T.. the dimensions are limited us follows:--
Ft. Ins. Length (approximate) 720-0 Loaded draught Beam
36 9 99 0
The above draught allows 1 ft. 6 ins. under the vessel's bottom at the outer eill, which is 4 ft. lower than the inner sill.
(n) A vessel of 530 ft. in length and of corresponding brain can be berthed aloug- side No. 8 Jetty, where the depth with dredging would be about 27 ft. to 28 ft. at lowest low water, which only occurs in the months of February and March, (b) A vessel of 560 ft. in length and of 78 ft. beam can be admitted direct into the Dock basin, but ordinarily the entrance lock is used, which admits vessels of 510 ft. in length, 58 ft. Ġ ins. Leam, and 27 ft. draught.
Colombo.
Ses answer to question 4.
The largest vessel hitherto berthed in Colombo Harbour is the Hamburg America
Co.'s S.S. **Cleveland. Length, 588 ft. 9 ins., beam 65 ft. 8 ins.. and loaded draught about 34 ft.
INDIA AND THE EASTERN COLONIES.
Hong Kong.
Holt's Wharf is a T wharf 470 ft. long. Room, with overhang at each end, for ship 700 ft. in length. Total wharf accommodation about
5,000 ft. Ninety per cent. of shipping lies at buoys, of which there are 12 in the harbour privately owned.
The existing capacity of the port for
large ships is as follows:-
Holt's Wharf-Vessels of 600 ft. to ft. beam and 700 ft. length,
30 ft. draught (one berth). Kowloon Wharves.-Vessels of 500 ft. to 600 ft. length, beam and 24 ft. draught. Six berths und a prospective wharf 600 ft. long and 30 ft. depth.
+1
Eight mooring Imoys capable of taking vessels of 1,000 ft. in length,
ft. bean and 36 ft. draught. Four mooring buoys capable of taking vessels of 1,000 ft. in length, ft. beem and 10 ft. draught.
Singapore.

The length of quays with a depth of 33 ft.
(L.W.O.S.T.) is at present 1,200 ft. There is wharfage accommodation in addition to the above some 5,000 ft. in length with from 22 to 30 ft. depth of water alongside (L.W.O.S.T.). This is in course of reconstruction to provide a minimum depth of 33 ft. of water (L.W.O.S.T.).
In addition to the reconstruction of the main wharves, a tidal basin or wet dock has been constructed 24 acres in extent, with a depth of 30 ft. (L.W.O.S.T.) which provides a further 3,800 ft. of berthing accommodation.
Quay space is also being provided for small vessels in the harbour, 4,139 ft. long, with a depth alongside of 18 ft. (L.W.O.S.T.).
Ships of any length and beam with draught not exceeding, say, 32 ft. can be berthed.
7. What are the dimensions Gength, breadth and depth over sill H.W.O.N.T.) of the largest dry dock or floating dock in the port
There is a floating dock, the
dimensions of which are as follows:--
Length over end platforms 230 ft.. breadth between wall 53 ft. 4 ins.
The dock can take a steamer of 1,400 tons displacement sad up to 15 ft. draught. This dock belongs to & private firm.
