[" Toorak."—1. You appear to have taken every care to establish a good sward on your green, and the only conclusion that we can arrive at is that the weeds were in the seed. […]1 2. Baron Von Mueller identifies the plant you send as the Gnaphalium japonicum,2 a native of Australia. It is perennial, but may with ordinary care be got rid of.]

Letter not found. The text given here is from 'The Yeoman. Answers to correspondents', Australasian (Melbourne), 18 April 1896, p. 725. Assuming that the reply would be published in the next available issue in this weekly newspaper, it is dated to 10 April 1896 as the likely earliest date it would have been sent.
