 By an order which came into force in 1898, regulating the navigation of Southampton Water, all sailing vessels must give way to steamers of 1000 tons or over. On the Thames and Mersey there has for some time existed an unwritten law to the same effect, which it is expected will shortly receive the sanction of the legislation.

The following are the Board of Trade regulations relating to pilot signals:—
