Sanderson's propaganda of this idea of the possible reorganisation of the world through schools came to an abrupt¹ end in the summer of 1922. He died suddenly of heart failure in the Botanical Theatre of University College, London, at the end of an address to the National union of Scientific Workers. He had chosen as the title of the address, 'The Duty and Service of Science in the New Era,' and it was in effect a recapitulation of his most characteristic views. He attached considerable importance to the delivery and he made unusual preparations for it.  
Upon his desk after his death seven separate drafts, and they were all very full drafts, of this address were found. In the margins² of the pages little sums have been worked out—so many pages[Pg 148] at three hundred words a page, four thousand, five thousand words; a full hour's talking, and still so much to say! There are little notes framed in a sort of Oxford³ frame of lines reminding him, for example, to 'say more of bringing scientific method into all parts of school.' On the reverse of the pages of manuscript are trial restatements. He tried back several times to a fresh beginning. There is a page headed 'The New School,' and giving three headings: the first, which he afterwards marked as second, is, 'The faculty⁴ of each member shall be developed'; the second, which became the first, is 'Community service—no competition'; the third is, 'Outlook—aim, more value than ability. Service. All are equal. The Spirit and the Bride say, Come. Let all that will, come.'
 
Then we find him trying over his ideas about science under a heading, 'What we claim for science.' Under that are a number of interesting subheads:—
 
'Its own value in the great discoveries.
 
'That its spirit is that of life, giving, changing, searching. (Marginal note:—without being[Pg 149] deterred⁵ by any of the results which may follow.)
 
'It is "natural" to the vast number of boys.
 
'Very directly applicable to needs.
 
'That it has a language and a message. (Marginal note:—it seeks to test, to create new standards, to fearlessly rewrite knowledge.)
 
'The same spirit. (? as Christianity: Editor.)
 
Finally he produced a draft which was at least his eighth. This he had printed and this he may have intended to read to the meeting. But he did not do so. In the end he spoke⁶ from a fresh set of notes, which must have been at least the ninth draft. T............
