Sweeping Operations.

H.M. Vessels are constantly engaged in sweeping operations off ports in the United Kingdom.

Whilst so engaged, they work in pairs connected by a wire hawser, and are con- sequently hampered to a very considerable extent in their manoeuvring powers.

With a view to indicating the nature of the work on which these vessels are engaged, they will show the following signals:

A black ball at the foremast head and a similar ball at the yardarm, or where it can best be seen, on that side on which it is dangerous for vessels to pass.

For the public safety, all other vessels, whether steamers or sailing craft, must keep out of the way of vessels flying this signal, and should especially remember that it is dangerous to pass between the vessels of a pair.
