|30 April 1915
|'I send you the only copy we can spare of the report sent in by you and Mr Hill in July 1914; but I can find no trace of the second report which you say was sent in about April 10th of this year. We have no record of its having been sent direct here, and Mr PArsons to whom I have applied, has no record of it.'
