Your telegram 133 of 8th September. 
I fully discussed with Sir John Anderson position with regard to
tube alloy  work in America and at Montreal. As you know, this
work was originally started in England under the direction of the
D.S.I.R.  but was transferred to America as being more suitable
than these Islands for experimental work that had to be done.
Work in America was a joint Anglo-American project but has
increasingly passed under American direction. The work being clone
in Montreal is by a purely British team working on a different
line from that being followed in America. The greatest secrecy is
being observed and the Americans are particularly sticky about new
workers being introduced and only specifically named individuals
who have particular qualifications are being accepted.
In regard to work at Montreal no further physicists are required
but the group could make use of a chemical engineer or a
mechanical engineer with chemical experience and it has been
tentatively suggested that Australia might be able to provide this
The upshot of my conversation with Sir John Anderson was that he
is consulting with his technical advisers and will further advise
me later. In our conversation Anderson emphasised that all the
present work is directed towards the military aspect. Should
future developments lead in the direction of industrial and
economic utilisation he recognises there would have to be a
reconsideration of the whole position.
