Cautiously he craned his head over the edge of the flake, carefully keeping his weight as well back as he could. There was a ledge about two feet lower than the flake, very narrow, not more than three or four inches there; but having seen so many of these ledges in the quarry before, he had no doubt it widened. As that was the extreme end, it would be narrowest there. He thought he could get his foot on it, but the difficulty was what to hold to. It was of no use putting his foot on a mere strip like that unless there was something for his hand to grasp. Bevis saw a sand-martin pass at that moment, and it occurred to him that if he could find a martin’s hole to put his hand in, that would steady him. He felt round the edge of the groove, when, as he extended himself to do so, the flake tipped a little, and he drew back hastily. His chest thumped with sudden terror, and he sat still to recover himself. A humble-bee went by round the edge of the groove, and presently a second, buzzing close to him, and seeing these two he remembered that one had passed before, making three humble-bees. “There must be thistles,” said Bevis to himself, knowing that humble-bees are fond of thistle-flowers, and that there were quantities of thistles in the quarry. “If I can catch hold of some thistles, perhaps I can do it.” He wanted to feel round the perpendicular edge again, but feared that the flake would tip. In half a minute he got his pocket-knife, opened the largest blade, and worked it into the sand farthest from the edge--in the corner--so as to hold the flake there like a nail. Then with the utmost caution, and feeling every inch of his way, he put his hand round the edge, and moving it about presently felt a thistle. Would it hold? that was the next thing; or should he pull it up if he held to it? How could he hold it tight, the prickles would hurt so. He knew that thistles generally have deep roots, and are hard to pull up, so he thought it would be firm, and besides, if there was one there were most likely several, and three or four would be stronger. Taking out his handkerchief, he put his hand in it, and twisted it round his wrist to make a rough glove, then he knelt up close to the sand wall, and steadied himself before he started. The flake creaked under these movements, and he hesitated. Should he do it, or should he wait till Mark missed him and searched? But the battle--the battle might be lost by then, and Mark and all his soldiers driven from the field, and Pompey would triumph, and fetch long ladders, and take him prisoner.
