In the Works and Correspondence of David Ricardo (Volume X) Piero Sraf
fa noted that the Mill-Ricardo case of the Ricardo Papers deposited at
Cambridge contained 'a paper probably in Bentham's hand-writing on th
e effects on profits of cultivating successive qualities of land'. In
1978 I made a search of the Ricardo Papers and no such document was to
be found. This note reports the discovery in Trinity College Library-
and provides a transcription-of a document that may be the elusive ite
m, though it is in James Mill's hand. (C) 1996 Academic Press Limited
