It was now no longer necessary or even possible to steer the Astronef. She was directed solely by the repulsive force which would carry her with ever-increasing swiftness, as the attraction of the earth diminished, towards that neutral point at which the attraction of the earth is exactly balanced by the moon. Her momentum would carry her past this point, and then the "R. Force" would be gradually brought into play in order to avert the unpleasant consequences of a fall of some forty odd thousand miles.
Andrew Murgatroyd, relieved from his duties in the wheel-house, made a careful inspection of the auxiliary machinery, which was under his special charge, and then retired to his quarters in the after end of the vessel to prepare his own evening meal.
Meanwhile, her Ladyship, with the help of the ingenious contrivances with which the kitchen of the Astronef was stocked, had prepared a dainty little souper à deux. Her husband opened a bottle of the finest champagne that the cellars of Smeaton could supply, to drink to the prosperity of the voyage, and the health of his beautiful fellow-voyager. When he had filled the two tall glasses the wine began to run over the side which was toward the stern of the vessel. They took no notice of this at first, but when Zaidie put her glass down she stared at it for a moment, and said, in a half-frightened voice:
"Why, what's the matter, Lenox? look at the wine! It won't keep straight, and yet the table's perfectly level—and see! the water in the jug looks as though it were going to run up the side."
Redgrave took up the glass and held it balanced in his hand. When he had got the surface of the wine level the glass was no longer perpendicular to the table.
"Ah, I see what it is," he said, taking another sip and putting the glass down. "You notice that, although the wine isn't lying straight in the glass, it isn't moving about. It's just as still as it would be on earth. That means that our centre of gravity is not exactly in line with the centre of the earth. We haven't quite swung into our proper position, and that reminds me, dear. You will have to be prepared for some rather curious experiences in that way. For instance, just see if that jug of water is as heavy as it ought to be."
She took hold of the handle, and exerting, as she thought, just enough force to lift the jug a few inches, was astonished to find herself holding it out at arm's length with scarcely any effort. She put it down again very carefully as though she were afraid it would go floating off the table, and said, looking rather scared:
"That's very strange, but I suppose it's all perfectly natural?"
"Perfectly; it merely means that we have left Mother Earth a good long way behind us."
"How far?" she asked.
