I don’t know why I am fascinated by this battered yard sale sale acquisition but I can’t stop delving into marine knowledge of another era. The book is a highly detailed manual of everything one needed to know to become a serious sailor in 1913. Well-thumbed, taped together, the book contains study notes, in real ink, browning at the edges, of its long-ago owner, one Francis Walsh of Nova Scotia.
From the book I learned how to deal with accidents during squall, how to adjust a sextant, how to send up a topgallant yard and rig out a jibboom, how to stow jute or cotton cargo, how to put out all lights and ban hobnailed boot with metal nails when powder or dynamite is coming board. Using a hand lead line, the helmsman must call out, “by the mark 5” when at 5 fathoms. (Mark Twain took his pen name from riverboat soundings.)
At the back are the Master’s Civil and Legal Duties and Board of Trade requirements. There is a fine of £500 for carrying passengers on more than one deck below the waterline. Should scurvy break out, issue a double allowance of lime juice and preserved vegetables such as cabbage and onions. Sighting of a derelict vessel must be reported to the Lloyd’s agent at the next port of call. A large red flag must be displayed on a destroyer or gunboat when submarines are exercising in the area.
The original wind scale made by Admiral Beaufort in 1805 has become obsolete in consequence of the changes in the rig of ships. With a hydrometer is found the draught which a ship should be loaded in fresh water of any density so as to have a given draught in sea water. In a heavy squall to the windward under reefed sails, lower away and furl the upper topsails. Use a clove hitch for hitching ratlines to the shrouds.
Communication is a big concern for all vessels. Morse Code, for example, is laid out, letter by letter, ready for learning, only a part of skills to learn.
Lots of other useful information abounds. A fathom is six feet, a league is three miles, a ton of fresh water is 210 gallons, a cable is one tenth of a nautical mile. A ship’s coal consumption varies with the cube of the speed. The diameter and lenses of anchor lights should not be less than eight inches. The amount of water a vessel displaces is equal in weight to the vessel and cargo. A single vessel approaching a squadron of warships would be well advised to keep out of the way.
A vessel in distress can fire a gun or explosive device at one minute intervals, display a square flag above or below a ball or sound the fog signal continuously. Did the Titanic sound its foghorn for help? It must have had a big one which surely would have carried to ship it could see on the horizon.
And so the fascinating information goes on and on. I sincerely hope Francis passed his tests and eventually rose to captain. If he learned everything in Tait’s he would certainly be well qualified.
