Mousing a Hook

               Mousing a hook prevents the load from hopping
               out. But make certain before you apply the load
               that the load is on the hook, not on the mousing.

             Consider the things you want to lash. What shapes
             are they? What materials? How heavy? Under what
             conditions are they expected to remain together? Is  the other hand, long pieces are sometimes appropri-
