Just to show the lieutenant that I was having a good time, I buzzed up again and did two more vrilles, looking out the whole time at the panorama of Pyrenees, villages, and river, whirling around with the most amazing rapidity. Not a thing for bilious or easily dizzy people though, as it means horses at the walk if you fail to do the right thing at exactly the right moment. After the acrobatics, we went to classes in machine-gun shooting and combat-flying--very interesting and practical, but not to be talked about. After Pau, I had forty-eight hours' leave in Paris, bought a few things I needed for the front, and was then sent to a place it is forbidden to mention, expecting soon to get to flying over the lines. On New Year's morning, as it was snowing hard and there was no flying, I sat by a cozy fire, in the house of some English people. Curious thing, running into them here. They are of the tribe of English who wander over the face of the earth, and make England what she is. The man of the house is an expert on ----, and has pursued his unusual vocation in Cuba, Jamaica, Honduras, Guiana, "Portuguese East" and other parts of Africa, as well as in Ceylon and a few other places I forget. Here he is now, as expert for the French. His wife and seven children, who speak French, Portuguese, Spanish, and Zulu, I think, follow him everywhere, and are everywhere equally at home. I have tea with them after work, and, needless to say, they are a Godsend in this desolate place. Let us all pray that next New Year's day we shall be thanking God for a victorious peace and returning to civilian life, never to put on uniforms again. The finest uniform of all is the old civilian suit--brass buttons and gold braid to the contrary. For this winter air-work, which is the coldest known occupation, I think, this is the way we dress. First, heavy flannels and woolen socks. Over that, a flannel shirt with sleeveless sweater on top, and uniform breeches and tunic. Boots and spiral puttees (very warm things, if not put on too tightly) go on next, and over all we pull on a great combination, or fur-lined "teddy-bear" suit--waterproof canvas outside. Over our boots we pull fur-lined leather flying boots, reaching half-way up to our knees. For head-gear, a fur-lined leather cap, and around the neck, several turns of gray muffler. A variety of mask and a pair of "triplex" goggles to protect one's face from the icy breeze. With all this, and heavy fur gloves, one can keep reasonably warm.
