It seemed, however, that in their attempts to find the house they had covered more country than they remembered. The tracks meandered all over the place and gradually became fainter until, after half an hour's walk, they gave out altogether, having become filled up with fresh snow. This placed them in an extremely serious predicament as it meant that if they could not find the Ark they would have to remain out all night. Their only indication of the Ark's direction was that it must lie on lower ground, so they trudged down a slope hoping eventually to come to the water, which would give them the line of the shore. But the slope ended in a valley-bottom which rose to a steeper hillside, so, now silent and anxious, they turned back and tried the other way.
Lavina, who loathed the cold, was feeling absolutely desperate and cursed herself for having allowed her curiosity to overcome her reluctance to accompany the others on the expedition. But she knew no good purpose could be served by worrying the men, who were doing their best to find the way, so she said nothing. It was Margery who began to complain and irritated the others by nagging at them until Gervaise abruptly told her that she would do better to save her strength for further walking than to dissipate it in pointless criticisms.
For three hours they wandered, first in one direction and then in another, their spirits sinking lower and lower, until at last Hemmingway stumbled over the dead horse. They knew from its colour and position that it was the one which they had seen on first landing, so the Ark could not be very far away. While the rest remained near the horse, Derek set off at a brisk walk down the gentle gradient and kept in touch with the others by yodelling to them every few minutes. His first cast took him too far to the right; but when he felt that he must have passed his objective he turned back and began to move in a constantly increasing spiral, until he eventually came upon the giant snowball that the sphere had become in their absence. He then returned to the others and led them in along his last tracks.
It was past four in the afternoon when they wearily dragged themselves up to the door of the Ark, and as they had left it at nine o'clock in the morning they had been out in the snow for over seven hours, walking nearly the whole time; and for four of those hours they had been lost. In consequence they were frozen to the marrow, ill-tempered and thoroughly tired out. It was not until they had drunk some hot tea laced with rum that any return of cheerfulness manifested itself among them and they all agreed that never again would they leave the Ark during a snow-storm.
Even the tea and rum failed to warm Lavina. She sat shivering in a chair, her small face pinched and miserable until Derek, who thought of little else but her well-being, suggested that he should get her some hot bottles and that she should go to bed.
She thanked him with a pale smile and agreed that would be best; but she had a bad night and was feverish when she woke the following morning, having caught a nasty chill.
Gervaise doctored her and said that she had better stay in bed until she felt all right again, so she did not get up for the next three days; but she did not miss anything by remaining in her cabin as the snow continued to fall without interruption and the others did not leave the Ark except to stretch their limbs in its immediate vicinity.
The fact that they were now able to get away from each other by going outside their steel home enabled Sam and Margery to have some long talks while walking up and down in the snow. Sam reported the conversation he had had with Lavina and Margery derived much secret satisfaction from the way things had gone. She was surprised and pleased that Lavina had made so little trouble but gave her sister little credit for the fact that it was her direct mind and generosity which really formed the basis of the agreement.
In Margery's eyes, Sam had done the right and manly thing in tackling Lavina without delay, and she felt sure that it must have been Sam's own firmness which had carried the tricky interview through to a successful conclusion. The very fact that Sam insisted on giving Lavina full marks only made Margery admire him the more for his strength and modesty, and she felt that her sister, although impetuous and self-willed, must be a weak creature underneath to have surrendered her man with hardly a struggle. Margery had no doubts in her own mind that with Lavina nominally out of the way she could now safely count on having Sam to herself; but then, she did not really know Lavina.
Being able to leave the sphere made a great difference to Derek as he was able to get as much exercise as he wanted without being dependent on the weather, and whenever he was not engaged trying to amuse the sick Lavina in her cabin, or asleep in his own, he was out in the frosty, snow-filled air which he thoroughly enjoyed.
As he soon grew tired of walking up and down within sight of the Ark he decided to employ himself in banking the snow up under its platform and cutting a set of steps in the bank up to its door. Some of the others helped him in his shovelling from time to time and the business was completed by the end of the second day of Lavina's indisposition.
It then occurred to him that it would be a good thing for Fink-Drummond, too, to have some exercise, so he brought the madman up from his prison, muffled him in a warm coat and, taking him outside, walked him up and down. As he could only take very short paces, owing to the chain which linked his ankles, the experiment did not prove very successful and such slow-going was anything but pleasant with the thermometer well below zero.
It was a long time now since Fink-Drummohd had had one of his fits of insanity, although he still remained apparently dumb; so, having decided that there was little risk of trouble as long as he was in this quiet mood, Derek borrowed Hem-mingway's loaded crop in order to defend himself if he was attacked and undid the padlock which secured the chain round the prisoner's legs. The result justified his humane gesture as the lunatic seemed delighted at the chance to stretch himself properly, and behaved quite perfectly, even when he was led back to his cell afterwards and had the chains replaced on his feet.
It was on the fifth day after they had been lost that the snow at last ceased falling. White clouds heavy with it still lingered overhead, but once again they were able to see the surrounding country. To the south of them the great flood had disappeared but the five days' fall of snow had been so heavy that it was impossible to pick out the characteristics of the landscape in detail. On every side they could see long, rolling slopes of snow running into other slopes until these gradually faded into the distance, while in the foreground the universal whiteness was broken here and there by a hedge or coppice that had not been completely covered. They had just decided to set out on another expedition to try and find the grey stone house when the clouds parted and a pale sun shone through.
It was ten days since Gervaise had had a chance to shoot the sun so he immediately got out his sextant, and so eager were the others to know in what country they had come to earth that all thought of the expedition was abandoned while he took an observation and worked out their position. At last he said:
'Our latitude is now 71 degrees 26 minutes north.'
"Then we're still right up in the Artie Circle,' Hemmingway said at once, 'and much farther north than Iceland.'
'I think we must be in Greenland,' Gervaise replied, 'although I'd never imagined that its scenery looked anything like that which we saw here on the day we were washed ashore.'
'I hadn't, either,' Hemmingway agreed, 'but the scenery of the world doesn't vary quite as much as most people are apt to think. I've seen photographs of parts of semi-tropical Africa which look very like England; and in winter, when there's plenty of snow on the mountains, distant views of Greece might be mistaken for Norway later in the year. Still, if only the sky keeps clear you'll be able to get some altitudes of the stars tonight and fix our longitude; then we'll really know where we are.'
