Once within the swamp, we had to be careful not to deviate from the narrow track, which offered a firm foothold.

On each side lay shallow sheets of stagnant water overlying a treacherous bottom of semi-fluid mud, which rose above the surface here and there in moist, sweltering banks, mottled over with occasional patches of unhealthy vegetation. Great purple and yellow fungi had broken out in a dense eruption, as though Nature were afflicted with a foul disease, which manifested itself by this crop of plague spots.

Here and there dark, crab-like creatures scuttled across our path, and hideous, flesh-coloured worms wriggled and writhed amid the sickly reeds. Swarms of buzzing, piping insects rose up at every step and formed a dense cloud around our heads, settling on our hands and faces and inoculating us with their filthy venom. Never had I ventured into so pestilent and forbidding a place.

Mordaunt Heatherstone strode on, however, with a set purpose upon his swarthy brow, and we could but follow him, determined to stand by him to the end of the adventure. As we advanced, the path grew narrower and narrower until, as we saw by the tracks, our predecessors had been compelled to walk in single file. Fullarton was leading us with the dog, Mordaunt behind him, while I brought up the rear. The peasant had been sulky and surly for a little time back, hardly answering when spoken to, but he now stopped short and positively refused to go a step farther.

“It's no' canny,” he said, “besides I ken where it will lead us tae.”

“Where, then?” I asked.

“Tae the Hole o' Cree,” he answered. “It's no far frae here, I'm thinking.”

“The Hole of Cree! What is that, then?”

“It's a great, muckle hole in the ground that gangs awa' doon so deep that naebody could ever reach the bottom. Indeed there are folk wha says that it's just a door leadin' intae the bottomless pit itsel'.”

“You have been there, then?” I asked.
