...instrument hasn't a broad enough beam for its height. Since the drumheads are approximately six feet in diameter, the surface area of each is about 28 1-4 square feet, if you remember your plane geometry. When the calfskin is hit a good wallop, this makes quite a radius of vibration; unfortunately the sides are so close together that most of it is dissipated inside the drum, producing a low tone that doesn't carry very far. But the tone is there nevertheless, and the claim that the real boom is produced by a smaller instrument is absolutely unfounded...
...proclamation of martial law last Saturday, Governor Quinn declares that Narragansett Park and all the surrounding territory in Pawtucket within a radius of one mile is "in a state of insurrection." This conclusion rests on the following findings of fact...
...anywhere on earth. In a joint manifesto the British insurers said they think they have made "a substantial contribution to the cause of world peace," explained that property owners unable to take out war risk policies will be forced to start "working for peace," concluded: "The wide radius of action of modern aircraft has made the area of destruction almost illimitable. Incendiary bombs have increased enormously the potential damage to property. Writing of war risk insurance on land has become in fact little more than a gamble, which plays no part in insurance, where rates are based on scientific application...
...Theatre which would sponsor an annual Mohawk Drama Festival in July and August. Governor Lehman, the Boy Scouts and civic bodies all over the Mohawk Valley have enthusiastically sponsored the Festival. Colonel Frederick S. Greene, State Superintendent of Public Works, had Festival road signs posted in a 50-mi. radius of Schenectady, and this year, the Festival's third, he will be rewarded with a small part in The Farmer Takes a Wife. And this week another series of carefully presented revivals begins at Chautauqua, N. Y. when the able, 22-year-old Cleveland Playhouse company moves...
...Construct an angle, any angle. Bisect it. At a point, any point, on the line of bisection, draw lines to sides of angle and perpendicular to bisector. You have now got a straight angle within the original angle. Using the point as center and length of equal perpendiculars as radius, describe a semi-circle upon the straight angle and within the original angle. Trisect the straight angle by trisecting the semi-circle. The points of trisection of the straight angle will also trisect the original angle...
