Letter from William B Hardy to A D Hall Informs Hall that the Committee's role is to determine the physiological needs of [Allied] nations in calories, then arrange for any deficit between this and the home-produced food supplies to be transported -- feels that the right men could work out the problem, but 'whether the politicians would welcome the result of the work is, however, doubtful' -- asks if Hall could propose a French scientific agriculturalist for the Committee. 4 December 1917
