But he stayed to watch the Tank get under way, and after watching her performance and course for a few hundred yards he returned to his motor-bike with struggling doubts in his own mind as to how and in which direction he was likely to be the bigger fool—in believing or in refusing to believe. The Hotstuff snorted once or twice, shook herself, and rumbled internally; her wheel-bands made a slow revolution or two, churning out a barrowload or so of soft mud, and bit through the loose upper soil into the firmer ground; she jerk-jerked convulsively two or three times, crawled out of the deep wheel-ruts she had dug, turned, nosing a cautious way between the bigger shell craters, and then ploughed off on a straight course towards the road across the sticky mud—mud which the dispatch-rider had utterly failed to negotiate, and which, being impassable to him, he had, out of the knowledge born of long experience, concluded impassable to anything, light or heavy, that ran on wheels. A wide ditch lay between the field and the road, but the Hotstuff steered straight for it and crawled tranquilly across. The dispatch-rider watched the progress across the mud with great interest, whistled softly as he saw the Tank breast the ditch and reach out for the far bank, with her fore-end and nearly half her length hanging clear out over the water, gasped as the bows dipped and fell downward, her fore-feet clutching at and resting on the further bank, her bows and under-body—the descriptive terms are rather mixed, but then, so is the name and make-up of a Land Ship—hitting the water with a mighty splash. And then, in spite of himself, he broke from wide grins into open laughter as the Hotstuff got a grip of the far bank, pushed with her hind and pulled with her fore legs and dragged herself across. If ever you have seen a fat caterpillar perched on a cabbage leaf’s edge, straining and reaching out with its front feet to reach another leaf, touching it, catching hold, and letting go astern, to pull over the gap, you have a very fair idea of what the Hotstuff looked like crossing that ditch. She wheeled on to the road, and as the dispatch-rider, with mingled awe, amazement, and admiration, watched her lumbering off down it he saw an oil-blackened hand poked out through a gun port and waggled triumphantly back at him. “Damme,” he said, “I believe she _can_ swim, or stand on her head, or eat peas off a knife. She looks human-intelligent enough for anything.”
