...launched the first graduate studies in history in the U.S. As a practicing historian, he wrote a classic, nine-volume study of the Jefferson-Madison administration. He hobnobbed with the great, picked every first-rate brain of the Victorian era, traveled from the South Seas to the Arctic Circle, and finally totted up the findings of a lifetime in his pessimistic masterpiece, The Education of Henry Adams...
...change is most noticeable in Canada. The mean annual temperature of Montreal, said Dr. Kimble, has risen from 42°F in the 1880s to 46°F in 1950. Along the bleak natural boundary between Canada's forests and the barren Arctic, the trees are marching northward. Saplings of tamarack, spruce and birch are appearing where none grew before...
...final test, a magnetometer survey, was hastily completed just before the quick-coming arctic winter was about to close down. The scientists carried a sensitive magnetometer all around the crater, charting the magnetic lines of force. Under the northern rim they found what they were looking for: a "magnetic anomaly" indicating that a large mass of metal-bearing material lies buried far below the surface...
...Chubb Crater and the lake that now fills it will never be a handy tourist attraction like Arizona's meteorite crater near Canyon Diablo. It is close to Hudson Strait, on a granite plain so desolate that even arctic animals prefer to live somewhere else. Discovered by Prospector Fred W.

Then a hand-started blower drives the heated air over the engine proper, forces it through the crankcase and around the walls of the cylinders. In no more than ten minutes the engine is warm enough to start...
