                                                          identical loop into it, passing the second end in a

                                                          both ends into the eye in the middle.

                                                             It’s only because the scope of this book is not
                                                         encyclopedic that more suggestions have not been
                                                         included. But I couldn’t leave out the comments of a
                                                         Mr. John “Fud” Benson who wrote to say, “In tying
                                                         the Ashley Bend I was struck by its resemblance to
                                                         a two-strand Wall and Crown Knot. . . . ” Indeed,
                                                         the two knots are analogous, even though they are

                                                         Bends on a par with the Ashley Bend.

               to gauge their resistance to slipping. Each knot
               (tied in mohair—a very slick, springy material) was
               given a series of as many as 100 sharp, even tugs
               and rated by the number of tugs needed to pull it
               apart. The results were presented on page 273 of
               The Ashley Book of Knots, and are reprinted here
               with permission.
                  The figures in the table represent relative secu-
               rity and should be considered a guide only, since
               most bends will fare better in regular cordage.
               For example, the Sheet Bend is adequate for use
               in three-strand manila, hemp, and spun Dacron,
               but should not be used in slicker materials such
               as filament Dacron, nylon, most polypropylene, or
               any double-braid rope. In the latter cases, a more
               slip-resistant bend such as the Ashley or Strait is
               called for. Of the bends described above, the Sheet
               Bend fared the worst, coming apart after an aver-
               age of 22.3 pulls. Next came the Double Sheet Bend
               at 36.2. The Carrick Bend lasted through 70.8
               pulls, and the Ashley Bend endured 100 tugs with-
               out slipping at all.
                  The other three recommended bends were not
               included in the test, but my own experience leads
               me to rate the Ashley Hawser Bend in a league
