As I made clear in November 2011, it is evidence that the assumption has been falsified that James is requested to provide.

It's incredible to me that someone writing on the History of Economic 
Thought list wants "evidence" that Keynes considered saving not to be 
spending by income earners but a withdrawal from the expenditure 
stream!  Incredible also because every introductory macroeconomics 
students learns that meaning of saving.  Anyhow, Robert can look up 
Keynes's meaning of saving in the _Treatise_ (1930), volume 1, p. 172, 
the _General Theory_ (1936), pp. 74 and 210; Keynes's _Economic Journal_ 
articles (December 1937) and (June 1938).  (Joan Robinson, _EJ_, 1938 
repeats Keynes's definition of saving to mean a withdrawal from the 
expenditure stream.)  Robert can also check these pieces of evidence, in 
contrast with the classical explanation that savings are spent by 
borrowers, that is, saving is not cash hoarding (Smith, Ricardo, and 
J.S. Mill) in chapter 2 of _Keynes and the Classics Reconsidered_ 
(Kluwer, 1998), a volume to which he contributed a chapter (7).
