More than half of this money had been spent (where it was needed most) in nations firmly within the Russian orbit. Yugoslavia received $429 million worth of food, fuel, commodities, industrial supplies and other necessary aid, Czechoslovakia $270 million, Poland $474 million, Byelorussia and the Ukraine $250 million, and Albania $28 million...

He keeps watch on its movements, working through a corps of super-tough field men. They have to be tough: observations in comfortable latitudes are helpful but not sufficient. Pole spotters have to travel into the Arctic where the pole hides out. This year three Madillmen surrounded the pole, set up delicate instruments to chart its lines of magnetic force...
...earth's favorite playmates in the lonely vastness of space is the Gia-cobini-Zinner comet, which sweeps around the sun in a lopsided orbit once every six and a half years. In 1933, two sweeps ago, the earth passed within 500,000 miles of the place where the comet had been 80 days before. The result: a gaudy shower of meteors...
...clear the earth with speed to spare, says Professor Herrick, a space ship should start at 8 miles per second. Once clear, it becomes a miniature planet with an orbit of its own. The gravitation fields of surrounding bodies pull it hither & yon. By taking advantage of these pulls, the space navigator can guide his ship...
keep the glider in the earth's orbit, so the great pull of the sun would make it spiral inward toward the orbit of Venus...
