(Due to arrive Melbourne-24.4.26)
My dear P.M.,
Many thanks for your long letter of 16th January.  I am very glad to know the way your mind is working on the several important problems you speak about.
With regard to your American trip, I will try to produce some material for speeches in the near future and will post it to you at once.
I am much looking forward to your visit to this country and to the opportunities that it will give to discuss the many subjects of interest in your letter.
With my best wishes, I am, Yours sincerely, R. G. CASEY
