"I am really _sorry_ that we shall not be able to spend the holidays together this year, as we have often done so _delightfully_ in the past, but I feel that I am only doing _what is right_.  It is _so important_ in these terrible times that everybody should practise the _strictest economy_ in food; and every one must do what he (_or she_) can for our dear country; and I have every hope that by going about the villages in my caravan, as I told you in my last, and delivering simple lectures on the greens and other public places, I may persuade the dear people, _especially the mothers_, that it is not _really necessary_ to health to have _both_ bacon _and_ eggs for breakfast _every_ morning.  If you were a little older and more experienced I am sure that you would be able _and willing_ to give me _very great_ assistance; but after your _arduous labours_ at school I feel you need complete rest from brain work, and you will get that nowhere so well as with _dear_ Mr. and Mrs. Trenchard.  To make up for your disappointment in being deprived of our usual simple pleasures I send you a little pocket-money, which I am sure you will spend _wisely_.  I _hope and believe_ that you will not indulge in luxuries; we all of us owe it to our _King and country_ to eat as little as we can.  You will find that _barley water and onions fried in margarine_ make an excellent light breakfast; will you tell Mrs. Trenchard that, _with my love_?  In the course of my tour I hope to reach Polstead before your holidays come to an end.  I will give you good notice, and rely on you to ensure me a _large audience_.
