She might well exclaim in astonishment. Instead of the landscape which had met their eyes before, there was nothing to be seen but a great white wall of mist that seemed to close them in on every side, as if some giant hand had suddenly drawn down a blind between them and the distance. "Whew!" exclaimed Ralph, starting to his feet, and indulging in a long-drawn-out whistle. "This is a nice fix! We're in the middle of a cloud. I never saw it coming up. It will be uncommonly awkward to get out of it. What a shame of old Pendle Tor to play us such a trick!" "Will it soon blow over, do you think?" asked Irene. "I don't know," replied Meta rather gravely. "Sometimes the clouds stay on these moors for days and days together. I wish we had noticed it sooner, and gone down to the road again before we were surrounded. I'm afraid it may be very difficult to find our way now." "I don't think it's any use waiting," said Leonard, "it mayn't clear for hours. We'd better pack up our traps, and make the best push we can to try to strike the path." "We must all stick close together," remarked Ralph. "It won't do to get divided, or we might never find each other again. We'd better keep well to the right; there's an old quarry on the left, and it wouldn't be exactly pleasant to walk into it. Luckily I've a pocket compass on my watch chain." Very much sobered in spirits, the picnic party hastily packed up the baskets, and, choosing Ralph as guide, set off down the hillside, hoping to find some track that would lead eventually into the road below. It was a strange walk, groping their way through what Monica described as "white darkness". The heavy mist hung in the air like a blanket, so completely shutting them in that they could scarcely see each other at a distance of even a few feet, and it was only by keeping near enough to touch one another that they managed to avoid being separated. Though they had some general idea of their direction, they did not really know where they were walking, and stumbled blindly on through heather and bilberry bushes, over stones and rocks, only feeling that they were going downhill. It was very slow progress. Ralph stopped continually to consult his compass, and occasionally gave a loud "cooee", in case they might find some wandering shepherd or countryman who would be able to help them. There was no answer to his calls, however--only the occasional bleat of a sheep that sounded far off and muffled through the mist. They knew there was neither cottage nor farm within hail, and unless they could strike the road they might wander on hour after hour over the moors, only getting farther and farther out of their way. Tired out with the rough trudge, the girls at last declared they must sit still for a few minutes and rest.
