Besides the book of ship's rules, every master when first appointed to command a ship is addressed by special letter from the company, of which the following passage is an extract: You are to dismiss all idea of competitive passages with other vessels and to concentrate your attention upon a cautious, prudent, and ever-watchful system of navigation, which shall lose time or suffer any other temporary inconvenience rather than incur the slightest risk which can be avoided. Mr. Sanderson, one of the directors, in his evidence says with reference to the above letter: We never fail to tell them in handing them these letters that we do not wish them to take it as a mere matter of form; that we wish them to read these letters, and to write an acknowledgment to us that they have read them, and that they will be influenced by what we have said in those letters. THE ROUTE FOLLOWED. The _Titanic_ left Southampton on Wednesday, April 10, and after calling at Cherbourg, proceeded to Queenstown, from which port she sailed on the afternoon of Thursday, April 11, following what was at that time the accepted outward-bound route for mail steamers from the Fastnet Light, off the southwest coast of Ireland, to the Nantucket Shoal light vessel, off the coast of the United States. It is desirable here to explain that it has been, since 1899, the practice, by common agreement between the great North Atlantic steamship companies, to follow lane routes, to be used by their ships at the different seasons of the year. Speaking generally, it may be said that the selection of these routes has hitherto been based on the importance of avoiding as much as possible the areas where fog and ice are prevalent at certain seasons, without thereby unduly lengthening the passage across the Atlantic, and also with the view of keeping the tracks of "outward" and "homeward" bound mail steamers well clear of one another. A further advantage is that, in case of a breakdown, vessels are likely to receive timely assistance from other vessels following the same route. The decisions arrived at by the steamship companies referred to above have, from time to time, been communicated to the Hydrographic Office, and the routes have there been marked on the North Atlantic route charts printed and published by the Admiralty; and they have also been embodied in the sailing directions. Before the _Titanic_ disaster the accepted mail steamers outward track between January 15 and August 14 followed the arc of a great circle between the Fastnet Light and a point in latitude 42° N. and 47° W. (sometimes termed the "turning point"), and from thence by Rhumb Line so as to pass just south of the Nantucket Shoal light vessel, and from this point on to New York. This track, usually called the outward southern track, was that followed by the _Titanic_ on her journey.
