PART III. WORKING KNOTS

Vines used as ropes, and knots tied in them, may have been
the first technical devices used by humans to help them with
their daily tasks. Part III presents historical accounts of two
fields of knots where their working uses and importance in
the service of mankind are clearly defined and acknowledged.

The knots and ropes used by seamen and fishermen play a
significant role in the history of knots. The first chapter de-
scribes some of this history, and discusses the rope problems
encountered by persons who sail boats and bring fish from
the seas.

The second chapter deals with a broad class of knots which
the author calls life support knots. Under this heading he
groups the cordage and knots used in activities such as moun-
taineering, rock climbing, rescue work, abseiling, and caving.
He traces the historical development of these activities, and
describes many of the knots used in them, paying special
attention to the properties required of them in life support
tasks.
