Therefore he only waited awhile for fear of being discovered, till Master Huckaback turned to the left and entered a little gully, whence he could not survey the moor. Then John remounted and crossed the rough land and the stony places, and picked his way among the morasses as fast as ever he dared to go; until, in about half an hour, he drew nigh the entrance of the gully. And now it behoved him to be most wary; for Uncle Ben might have stopped in there, either to rest his horse or having reached the end of his journey. And in either case, John had little doubt that he himself would be pistolled, and nothing more ever heard of him. Therefore he made his pony come to the mouth of it sideways, and leaned over and peered in around the rocky corner, while the little horse cropped at the briars.
But he soon perceived that the gully was empty, so far at least as its course was straight; and with that he hastened into it, though his heart was not working easily. When he had traced the winding hollow for half a mile or more, he saw that it forked, and one part led to the left up a steep red bank, and the other to the right, being narrow and slightly tending downwards. Some yellow sand lay here and there between the starving grasses, and this he examined narrowly for a trace of Master Huckaback.
At last he saw that, beyond all doubt, the man he was pursuing had taken the course which led down hill; and down the hill he must follow him. And this John did with deep misgivings, and a hearty wish that he had never started upon so perilous an errand. For now he knew not where he was, and scarcely dared to ask himself, having heard of a horrible hole, somewhere in this neighbourhood, called the Wizard's Slough. Therefore John rode down the slope, with sorrow, and great caution. And these grew more as he went onward, and his pony reared against him, being scared, although a native of the roughest moorland. And John had just made up his mind that God meant this for a warning, as the passage seemed darker and deeper, when suddenly he turned a corner, and saw a scene which stopped him.
For there was the Wizard's Slough itself, as black as death, and bubbling, with a few scant yellow reeds in a ring around it. Outside these, bright water-grass of the liveliest green was creeping, tempting any unwary foot to step, and plunge, and founder. And on the marge were blue campanula, sundew, and forget-me-not, such as no child could resist. On either side, the hill fell back, and the ground was broken with tufts of rush, and flag, and mares-tail, and a few rough alder-trees overclogged with water. And not a bird was seen or heard, neither rail nor water-hen, wag-tail nor reed-warbler.
