Abstract
THE comment made by Prof. Piaggio in NATURE of March 21, upon the address by Sir Arthur Eddington, cites the famous prophecy by Sir William Crookes, made near the end of the last century, as to the probable wheat supply in the future, say thirty years from the time of his address. The comment indicates that the present wheat surplus is due to the recent advances in fixing nitrogen and making new fertilisers. Sir William Crookes saw future controlled nitrogen fixation as the gleam of light amid the murky gloom of anticipated short wheat rations. While modern fertilisers may have had a slight influence in bringing about the present flood of wheat, their effect has certainly been a minor one.
