Q.-How is the Commercial Code applied in making Boat Signals ?

A.-The Distant Signals are used. The symbols of Square Flags, Pennants, and Balls, can be made with handkerchiefs and hats. These signals are made from right to left, and read from left to right. (See page 378).

Q.—What means are there for reporting ships passing along the English Coast.

A.-Signal stations have been established at many of the salient points of the coast, * and on ships passing and making their names known by Commercial Code Signals, the officers in charge of the stations forward reports to the "Shipping Gazette" for publication.

Q. How are Signal Letters for the purpose of making a ship's name at sea to be obtained for British Registered ships?

A.-By applying to a Registrar of Shipping at one of the Custom Houses, or to the Registrar General of Seamen in London.

The Signal Stations already established are as follows:-Broadstairs, Deal, Dover, Dungeness, Yarmouth (Isle of Wight), Prawle Point (near the Start), Caldy Island (Tenby), Great Yarmouth, Flambro' Head, and Bridlington.

At these Signal Stations the Commercial Code is the only Code recognised, and vessels of any nation which make their names known in passing these stations by means of the Commercial Code will be reported in the “Shipping Gazette.'

At present the duties of the officers at the Signal Stations will be limited to forwarding reports, of vessels passing, for publication in the “Shipping Gazette,” but at some future time, when the telegraph system is extended, these Signal Stations may be made still more useful to the mercantile marine of this country by being the means of forwarding urgent messages from the owners to their ships or vice verså
