My dear Prime Minister,
Gepp  left this morning after a few last hectic days completing as many things as were possible to complete and so far as development and scientific research was concerned, making arrangements with me for the continuation of the investigations which have been commenced.
I have been very glad to have had the opportunity of getting to know him as well as I have and I should rather like to stress one point to you-a point which, needless to say, I have fully stressed to Gepp himself. I feel that he has so active a mind and so much enthusiasm that there is a quite real danger of his overdoing things to the detriment not only to his health but perhaps even to the work of the Commission.
I think it would really be a most useful thing if you were to ask Gepp to make a point of avoiding Saturday work whenever he is in Melbourne. I presume he will find it necessary to travel about a good deal. When he is away from Melbourne, he will doubtless find it essential to work any and every day but while in Melbourne if he freed himself from all questions affecting the Commission on both Saturday and Sunday, I think it would be to the general advantage not only to Gepp personally but also to the whole work on which he is engaged.
I had Sir James Cooper  to lunch with me to meet Gepp and they made a very favorable impression of one another, with the result that Gepp invited Cooper to act on the Advisory Committee  which, with I understand your approval, he has decided to set up at Australia House.
Yours sincerely, F. L. MCDOUGALL
