Now a Canadian inventor, Scott Alexander, 55, has developed a new device that breaks ice upward. The new present seagoing ice plow, called the Alexbow, may well render present-day icebreakers obsolete...
Since the trials, Alexander has refined his Alexbow. Pushed by a 2,500-h.p. tug, he says, it can now tackle ice from three to four feet thick. He also proposes a detachable version that could be fitted to any vessel, and a plow that could be built onto the bow of a ship during construction. "There is no question in my mind," he says, "that one day icebreakers will no longer be used. Cargo ships themselves will do the ice-breaking." In a prelude to such an era, two Alexbow-equipped barges will be driven...
...present, there is little doubt that defoliation operations will continue. Says the MRI report: "The ecological changes caused by herbicides at the current rate of use have in no measure reached the proportion of ecological disturbance caused by the plow, ax and uncontrolled burning...
...prose style of Harvard's course catalogue can make a literate student pretty drowsy. Most programs are chosen by word of mouth, and among those students who plow regularly through their catalogues, there is a tendency to dismiss whole areas of human endeavor, like Soil Mechanics and Urdu, which appear to the untrained eye irrelevant. Yet a careful reading of the catalogue brings scholastic joy to a small, notoriously uncommunicative group of undergraduates who have effected a virtual monopoly over the University's more exotic, which is to say more enjoyable, selections. Opposing monopoly, we bring this list forthwith...
