John Maynard Keynes: Letter to Roy Harrod, July 4, 1938:
Tilton, Firle, Lewes.
4 July 1938
My dear Roy,
There is no doubt that your Presidential Address [to the British Economic Associaton] which I have sent to the printer [for the next issue of the Economic Journal], is very interesting; and it will provoke plenty of thought. Indeed it is much the best Presidential Address for many years. I am very glad to print it in full; but I would remind you that it will take considerably over an hour to read at a reasonable pace.
