GOVERNMENT NOTIFICATION.—No. 291.
The following Hydrographic Notice is published for general information.
By Command,

LOCAL NOTICE TO MARINERS, No. 54.
Wusung Bar Dredging Operations.
Notice is hereby given that on and after the 19th instant, whenever the dredger Anding is at work, or in a position for working on the Bar, symbols will be hoisted at her masthead to indicate her position relatively to the line of Bar Marks, as follows:-
ONE DIAMOND; to show that she is on the line of Bar Marks.
ONE BALL; to show that she is in a position to the North of the
line of Bar Marks.
TWO BALLS; to show that she is in a position to the South of the
line of Bar Marks.
The Anding will as a rule be moored with four, or possibly more, anchors, the positions of which will generally be marked by wooden spar buoys painted red. The buoys will be attached to the anchors by the shortest lengths of chain which it may be found practicable to use; as, however, they are liable to be carried away, or to be swept under by the current, absolute reliance cannot be placed on their being always seen.
2:
It is further notified that the depth signalled from Harbour Master's Wusung Station is the depth in the Channel in the line of the Bar Marks; allowance is not made for the height of the mushroom anchors above the level of the bed; this may be taken to be about three feet.
Night signals to indicate the depth will not be shown when the Dredger is on the Bar. It is however intended to remove her during the strong Spring tides in the summer months.
Attention is again drawn to the necessity that all steamers should go dead slow when passing the Dredger, whether she is actually at work or not; and all responsibility for damage or loss resulting from an infringement of this rule will rest with the offending vessel.
