In 1901 the development of the petrol engine was still so slight that it did not admit of the construction, by any European maker, of an engine weighing less than 12 lbs. per horse-power. Manly, working at the instance of Professor Langley, produced a five-cylindered radial type engine, in which both the design and workmanship showed a remarkable advance in construction. At 950 revolutions per minute it developed 52.4 horse-power, weighing only 2.4 pounds per horse-power; it was a very remarkable achievement in engine design, considering the power developed in relation to the total weight, and it was, too, an interruption in the development of the vertical type which showed397 that there were other equally great possibilities in design. I'll run upstairs and bathe my eyes, and I shall still have time to write before dinner, said Castalia, and left the room.

There is the bald narrative, but it is worthy of some amplification. If Ader actually did what he claimed, then the position which the Wright Brothers hold as first to navigate the air in a power-driven plane is nullified. Although at this time of writing it is not a quarter of a century since Ader鈥檚 experiment in the presence of witnesses competent to judge on his accomplishment, there is no proof either way, and whether he was or was not the first man to fly remains a mystery in the story of the conquest of the air. A book reviewer since 1967, including a five-year stint as editor of the Sunday Times Book Review, Leonard also write a warmly personal, frequently humorous column in the Wednesday Times titled "Private Lives." A collection of 69 of the columns appeared in book form last year under the title Private Lives in the Imperial City (Knopf, $8.95). In addition, he has published four novels and hundreds of free-lance articles for magazines ranging from Playboy to the New Republic. For years he wrote TV reviews for Life magazine under the pseudonym "Cyclops." Recalls Leonard: "It was a good way to turn your brain to Spam." Because of his various committee assignments and his strong support of most of Carter's policies, says Rangel, "I am forced to meet with the president more than probably many other members of Congress. I often stop by the White House on my way to the office." Rangel also likes to talk about Chip Carter, the president's son, who is involved in a project called City in Schools, designed to upgrade the neighborhoods outside certain schools. Chip has taken a special interest in Harlem, and one school in particular near Morningside Park. "I am confident that with Chip Carter's help, and with my help, Morningside Park will soon show some improvements. I hope that Columbia University will assist us too." WESTSIDER PAUL GOLDBERGER The development of the aeroplane between 1912 and 1914 can be judged by comparison of the requirements of the British War Office in 1912 with those laid down in an official memorandum issued by the War Office in February, 1914. This latter called for a light scout aeroplane, a single-seater, with fuel capacity to admit of 300 miles range and a speed range of from 50 to 85 miles per hour. It had to be able to climb 3,500 feet in five minutes, and the engine had to be so constructed that the pilot could start it without assistance. At the same time, a heavier type of machine for reconnaissance work was called for, carrying fuel240 for a 200 mile flight with a speed range of between 35 and 60 miles per hour, carrying both pilot and observer. It was to be equipped with a wireless telegraphy set, and be capable of landing over a 30 foot vertical obstacle and coming to rest within a hundred yards鈥?distance from the obstacle in a wind of not more than 15 miles per hour. A third requirement was a heavy type of fighting aeroplane accommodating pilot and gunner with machine gun and ammunition, having a speed range of between 45 and 75 miles per hour and capable of climbing 3,500 feet in 8 minutes. It was required to carry fuel for a 300 mile flight and to give the gunner a clear field of fire in every direction up to 30 degrees on each side of the line of flight. Comparison of these specifications with those of the 1912 trials will show that although fighting, scouting, and reconnaissance types had been defined, the development of performance compared with the marvellous development of the earlier years of achieved flight was small. Belinda, you do not realise the full extent. This is a more serious, a more frightful matter than you seem to think. Do you think she might鈥攕ome day? I have always been a rebel, she proclaims regally, dressed in a stylish Edwardian outfit with padded shoulders at her midtown office. Quite heavily made up, with hot pink lipstick and a Cleopatra hairdo, she looks considerably younger than her age. The strident quality of her voice is reminiscent of a Broadway chorus girl's, yet is delivered in a crisp, businesslike manner. During the interview she rarely smiles or strays from the question being asked. For some reason, she declines to say much about her new book, How to Look 10 Years Younger, which is scheduled for publication in April. Instead, she stresses the simple, common-sense rules about beauty that have guided her career from the beginning. I'll run upstairs and bathe my eyes, and I shall still have time to write before dinner, said Castalia, and left the room. Well, I daresay the thing was exaggerated, as so often happens. For my part, I never could see what there was in the girl to make so many people admire her. A certain freshness, perhaps; and some men do think a great deal of that pink-and-white sort of insipidity.
