My dear P.M.,

AIR DEFENCES OF AUSTRALIA

I enclose 'Times' announcement of Sir John Salmond's mission to
Australia. [1]

A Senior Officer of the Staff of the Imperial Defence College, of
whom Hankey [2] has a high opinion (but whom I am asked to keep
anonymous), writes privately to Hankey enclosing a memorandum on
the subject of Sir John Salmond's visit, of which, as you will
see, he does not approve.

Even admitting that there exists no accepted body of doctrine as
to the exact function and responsibility that the Air can take in
coast defence, it seems to me that this officer assumes too low an
order of intelligence and balance in Sir John Salmond. [3]

However, it is a point of view with regard to which you will no
doubt wish the Minister for Defence [4] to be aware.

I am, Yours sincerely,
R.G. CASEY
