It would scarcely be fitting that this Volume should go forth to the Public without a few words of Preface from one of A. L. O. E.鈥檚 own family. One such appeal had already been made and responded to by a gift of money. It had been made immediately after the arrival of the newly-married couple in Whitford, on the ground of the unforeseen expenses attendant on installing themselves in their new habitation. In answering it Lord Seely had written kindly, but with evident disapproval of the step that had been taken. "I cannot, Castalia," he said, "bid you keep anything secret from your husband, and yet I can scarcely help saying that I wish he did not know of the cheque I inclose. I fear he is disposed to be reckless in money matters; and nothing encourages such a disposition more than the idea that aid can be had from friends for the asking. Ancram will recollect a serious conversation I had with him the evening before your marriage, and I can only now reiterate what I then assured him of鈥攖hat it will be impossible for me to repeat the assistance I gave him on that occasion." The United States paid tribute to British efficiency by adopting the British system of training for its pilots; 500 American cadets were trained at the School of Military Aeronautics at Oxford, in order to form a nucleus for the American aviation schools which were subsequently set up in the United States and in France. As regards production of craft, the designing of the Liberty engine and building of over 20,000 aeroplanes250 within a year proves that America is a manufacturing country, even under the strain of war. Dr. Bodkin still lives and rules in Whitford Grammar School. His wife's life is brightened by the sight of her Minnie's increased health and strength. But she has never quite forgiven Matthew Diamond, and has been heard to say that young Mrs. Diamond's children are the most singularly uninteresting she ever saw! Theoretically the two-stroke and the four-stroke cycle engines possess exactly the same thermal efficiency, but actually this is modified by a series of practical conditions which to some extent tend to neutralise the very strong case in favour of the two-stroke cycle engine. The specific capacity of the engine operating on the two-stroke principle is theoretically twice that of one operating on the four-stroke cycle, and consequently, for equal power, the former should require only about half the cylinder volume of the latter; and, owing to the greater superficial area of the smaller cylinder, relatively, the latter should be far more easily cooled than the larger four-stroke cycle cylinder; thus it should be possible to get higher compression pressures, which in turn should result in great economy of working. Also the obtaining of a working impulse in the cylinder for each revolution of the crankshaft should give a great advantage in regularity of rotation鈥攚hich it undoubtedly does鈥攁nd the elimination of the operating gear for the valves, inlet and exhaust, should give greater simplicity of design. Horatia. The Aerolites.... 日本视频网站www色 Weasel. [Shaking his head.] There鈥檚 some others I know seem running the same road. For naval work, kite balloons were carried in a378 specially constructed hold in the forepart of certain vessels; when required for use, the covering of the hold was removed, the kite balloon inflated and released to the required height by means of winches as in the case of the land work. The perfecting of the 鈥楥oastal鈥?and N.S. types of airship, together with the extension of wireless telephony between airship and cruiser or other warship, in all probability will render the use of the kite balloon unnecessary in connection with naval scouting. But, during the War, neither wireless telephony nor naval airships had developed sufficiently to render the Navy independent of any means that might come to hand, and the fitting of kite balloons in this fashion filled a need of the times. My dearest Valentine.鈥? A most excellent young man! And, I'm sure, most devotedly in love with Rhoda. We find the temperature so comfortable here! said Violet. "Dear Castalia always has her rooms deliciously warm, we think."
