Reference your telegrams No. 160 dated 21st February [1] and No.

173 dated 12th April [2], regarding exchange bi-monthly service
liaison letters. Regarding the Air Department, the liaison letters
exchanged regularly between the Chief of the Air Staff [3] in
Australia and the Australian Air Liaison Officer, Ottawa [4],
appointed in connection with the Empire Air Training Scheme,
together with the reports of meetings of the Supervisory Board air
training plan forwarded to Australia provide a satisfactory
liaison so far as the Royal Australian Air Force is concerned. Any
information relating to the R.A.A.F. desired by the Canadian air
authorities could be obtained through the Australian Air Liaison
Officer and it is thought that this arrangement would meet
Canadian requirements. Navy consider progress not sufficient in a
fortnight to justify bi-monthly letters on naval matters but if
reports desired Navy suggest once a quarter would suffice. Army
also consider quarterly letters would meet requirements. If
Canadian Naval and Army authorities wish commence exchange letters
in accordance foregoing please advise so that authorities here may
be requested reciprocate [5]
