Yours ever, DINS. _December 19, 1917._ MY DEAR MRS. HALBERT: After all, it is the surprises that add the most spice, and it was certainly a pleasant surprise to receive your knit helmet. As a matter of fact, no gift could have been more aptly chosen. The only helmet I had was knit by a girl friend whose enthusiasm was greater than her skill; it no doubt represented much painstaking, but romance will not keep the head warm nor the ravelings out of one’s eyes when aloft, and I had wished hard and oft for a helmet of just the type you sent; others had them. Thank you so much for it, it fits perfectly. You probably know something of how my time has been spent. I am still in the LaFayette Flying Corps of the French Foreign Legion. We have been through four French schools of aviation and are now as good pilots as can be made without experience at the Front. We are now working in machines the same as are used at the Front, and engage daily in target practice and sharpshooting as well as the theory of gunmanship. We have been trained for pilots in the class machines, that is, fighting monoplane biplanes. They travel at a speed of from ninety to one hundred and fifty miles an hour; in a dive they will go two hundred and fifty or so. Aerial acrobatics in these machines are like a morning swim, and they have the appearance of a clipped-wing dragon fly. The life is wonderful and healthy and full of thrills. Every flight brings a new experience. We have flown circles around the highest peaks of the Pyrenees and swooped over the bathers at Biarritz. We have played hide-and-seek in the clouds and fought sham battles above them. One day I went to an altitude of 21,500 feet and froze three finger tips; I came down out of the sunshine through a snow storm and landed in the rain after sunset. Such changes were never possible before this age. They are a great strain on the system, and it is resisting that strain which is an aviator’s real work. The rest is play and sport. I would like to write more but must go to bed. Thank you again for your thoughtfulness. My best wishes for a happy, prosperous New Year to the Halbert family. As ever, sincerely, DINSMORE. _December 28, 1917._ DEAR FAMILY:
