The Extracts of Letters to Cronwright-Schreiner were produced by Cronwright-Schreiner in preparing The Life and The Letters of Olive Schreiner. They appear on slips of paper in his writing, taken from letters that were then destroyed; many of these extracts have also been edited by him. They are artefacts of his editorial practices and their relationship to original Schreiner letters cannot now be gauged. They should be read with considerable caution for the reasons given.. Cronwright-Schreiner has written the date and where it was sent from onto this extract, and that ‘When I got to Hanover I got the Col. Sec to send an expert mental Health officer up, who found the source of typhoid contamination, & the epidemic was thus stopped.’.
