...probably less than one-seventh the density of that of the earth. Because of its smaller mass, its gravity is much less and objects on its surface weigh only about one-third as much as the same objects would on the surface of the earth. It has also distinct polar caps, which increase and decrease with seasonable variations. It has also no marked clouds in its atmosphere. It has no surface elevations probably not over 2,000 or 3,000 feet in altitude. It has no oceans. Its year or period of revolution is close to 687 days...
...from a normal of between 1.94 and 1.98 to 1.90 in the past two years. This has lowered the temperature of the open oceans all over the world about 4½ degrees F. If this heat loss should become only twice as great, it is estimated that the permanent polar ice cap would descend over the subarctic and upper temperate zones. Canada would, become almost uninhabitable. Climates everywhere are now upset. Drought is threatening in India and California. These changes in the solar constant appear to move in cycles of about three years. Whether they have any relation...
...Pisa in Northern Italy, Roald Amundsen is testing the two special machines built by the German designer Dormier. In a few days he will fly north by way of Zurich, through Germany and Norway to Spitzenbergen. Thence to the North Pole and Alaska. In the barren wastes of polar territory, a forced landing means almost certain death...
When the rivers thaw the two parties will start downstream on the unknown courses of two of the large rivers (one of them the Colville), which flow into the Polar Sea. He may bring back good tidings of oil. He will surely return with a record of adventure...
...Norway. The expedition (set for July) plans to explore the territory between Spitzbergen, Norway, and Point Barrow, Alaska. Apart from collecting data for scientific aeronautics, Amundsen and Davison will explore 1,000,000 square miles of territory, and gather information as to the possibilities of commercial flying across the Polar regions-which may ultimately furnish the shortest route between the three continents of America, Europe and Asia. The Dornier plane has a radius of action of 1,300 miles; Spitzbergen is 500 miles from the Pole, but over 1,700 miles from Point Barrow. The explorers will, therefore, make several...
