There have been good reasons for the complaints about the answering of letters, acknowledgements of subscriptions and so on. Of our office staff of seven persons a couple of years ago, not one remains. Bill DeCosier, our first office boy, was shot down in his Spitfire over the North Sea a couple of months ago. Of the rest, two are now prisoners of war, one in the A.I.F., two engaged on munitions production and even little Patsy is now a WAAF! Recently we made arrangements with an established office to handle our business affairs. This should mean vastly improved service without any drain on manpower. With regard to our war effort: Mr. Straede is a physicist in a munitions factory; Mr. Keast handles his short-wave pages in his spare time, and personally, having been rejected on account of physical unfitness, I put in over 56 hours per week as manager of D. M. HULL & Co., an engineering factory engaged solely on war work. Under the circumstances we feel that we are doing our best to justify the confidence of the thousands of subscribers and supporters who are greater in number today than ever before in the seven years history of the publication. - A.
