%X The technique of the processor farm has become a very widely
   used for parallelising applications, often being mentioned
   without reference to any source.The goal of this work has
   been to put together a complete and rigorous understanding
   of what the technique can be used for and what is needed in
   order to arrive at an efficiently farmed application. This
   paper consists of these two parts.We have shown, via the
   UNITY theory of programming, that the basic structure of the
   processor farm may be used to parallelise a much wider
   domain of applications than has generally been
   considered.Second, we show by example, how to build
   efficient implementations for the first generation of INMOS
   Transputers. This work is new in that it is the first that
   has been able to test farming harnesses by taking an
   abstract view of the application.This paper has been written
   in a semi\-"instruction manual"" style. Also
   it should serve as an introduction to the subject.
