From then on the Engineers and New Jersey boats began to wobble and lose ground rapidly. Tech put it up to 32 at the mile and Rutgers soon afterwards to 35, but Chace had it steadied at 30 with a length and a half of open water to spare...
...powerful drive by the Jersey-men at the mile marked failed to gain any ground and they fell behind the Engineers. Different from their splashing contestants the Crimson blades kept the stroke down until the last minute when a snappy leg drive at 36 jumped the Bolles boat into a lead of a length and a half of open water...
...keep roaming dogs off his lawn, Arthur W. Burns, a Narberth, Pa. electrical engineer, strung a single wire around his property, a foot above the ground, attached the wire to his no-volt electric light system. When a trespassing dog grazed the wire last week, it got an electric shock, ran away yelping. Soon the Society for the Prevention of Cruelty to Animals heard about Mr. Burns's electric fence, asked for an injunction to compel him to remove it. Few days later the Philadelphia Electric Co. tested the fence, pronounced its amperage too low to harm dogs...
Currently there are some 250.000 miles of electric fence in use on more than 100.000 U. S. farms. Most of them consist of a single wire, though many farmers use two, or even three, for small animals. Two or three feet above the ground, the wires are connected with the no-volt electric supply line or to a 6-volt battery through a controller which governs the voltage and current so that the fence will shock livestock without injury. A survey Idaho took two years ago showed that the State's farmers are turning more & more to electric fences...
Leonardo da Vinci, who was so variously ambitious that he wanted to master birds' accomplishments as well as man's, declared in 1505 that no man would ever get his feet far off the ground until he had thorough knowledge of air and its currents. The invention of engines provided aviation with a shortcut, proved Leonardo partly wrong. But at the same time man did study the air, developed four types of motorless flying: gliding (coasting downward on still air); slope soaring (on rising air currents along the shoulder of a hill); cold front soaring (on the brow...
