‘Wait a moment,’ said I, ‘and let us see what is beyond. There may be a deepish hole there.’

We leaned over, and could see nothing. My companion got down from the boulder with a grave look.

‘I was just going to jump when you spoke,’ he said. ‘Lucky I didn’t. I wonder how deep it is?’

We hunted about for a stone, and by and by found one about the size of a man’s head. This the youngster tossed over the boulder into the darkness, and we stood looking at each other, by the little clear-burning light of the wax match. I do not know how long we stood there, for time has a knack of magnifying itself beyond belief in such conditions, but it was long, long before an awful hollow boom came rolling to our ears from the depth. We turned without a word, and stumbled back towards the daylight, and when we reached it I looked at the young Englishman and saw that all the roses had faded from his healthy young cheeks, and that he was as gray as ashes.

‘I was going to jump when you spoke,’ he said. ‘Precious lucky for me I didn’t.’

I congratulated him very heartily on not having jumped, and our search for natural wonders being ended we went back to the hotel. We made inquiry there—at first in vain—about this inner cavern, but at last we came across the Garde Champêtre of the district, who told us that the depth was unknown. He and some of his friends had had the curiosity to try to measure it, but they never had rope enough.

It befell on the morning of the next day that I wandered out alone, and in the course of the first score yards encountered Schwartz, who was demonstrative of friendly civilities. I returned his salutations, and he gave me to understand in his own too-humble manner that he would like to accompany me. I let him know that I should be delighted by his society, and away we went together. The ground was firm with last night’s frost and musical to the sabots of peasants and the iron-shod feet of horses. The hills and fields were covered with a powdery snow that threw their grays into a dark relief, and the air was so still that I could hear the bell-like tinkle of chisel and stone from the quarry nearly a mile away. We entered the Bois de Janenne together, and wandered through its branchy solitudes by many winding pathways. There is a main road running through this wood, cut by order of the commune for the pleasure of visitors, and the middle of this road was white with a thin untrodden snow. On either side this ribbon of white lay a narrower ribbon of gold where the pines had shed their yellow needles and the overhanging boughs had guarded them from the falling snow. The ground ivy was of all imaginable colours, but only yielded its secrets on a close examination, and did not call upon the eye like some of the louder reds and yellows which still clung to the trees. Here and there the fusain burned like a flame with its vivid scarlet berries—chapeau de curé the country people call them, though the colour is a little too gay for less than a cardinal’s wearing. For the most part the undergrowth was bare, and the branches were either purple or of the tone of a ripe filbert, so that the atmosphere, with the reflected dull golds and bluish-reds and reddish-blues, was in a swimming maze like that of a sunset distance, though the eye could scarcely pierce twenty yards into the thick-grown tangle.

Schwartz and I rambled along, now and then exchanging a sign of friendly interest, and in a while we left the main path and wandered where we would. Suddenly Schwartz began to hunt and sniff and bark on what I supposed to be the recent trace of a rabbit or a hare, and I stood still to watch him. He worried industriously here and there until he disappeared behind a clump of brushwood, and then I heard a sudden ‘Yowk!’ of unmistakable terror. After this there was dead silence. I called, but there was not even the rustle of a leaf in answer. I waited a while and called again, but still no answer came. Not in the least guessing what had befallen the dog, I mounted the hillside and came to the clump of bushes behind which he had disappeared. There I found a hole some three feet wide and two in height, a hole with sides of moist earth, formed like an irregularly-shaped funnel, and affording at its farther end little more than room enough for a creature of Schwartz’s size to pass. At the narrow end the earth was freshly disturbed.

I shouted down this reversed trumpet of a hole. I listened after every call I explored the place so far as I could with a six-foot wand cut from a near tree. I heard no movement, no whine of distress, and I touched nothing with the wand except the roof of the cavern into which poor Schwartz had fallen. At length I gave him up for dead, remembering the adventure of the day before, the terrible space of time which had elapsed before the echo of the fallen boulder came booming from the abyss, and thinking it as likely as not that Schwartz had fallen to an equal depth. When I got back to the hotel I told the tale as well as I could, and one of the servants took the news to Schwartz’s master.

When once this lamentable accident had happened, it became surprising to learn how frequently its like had happened before. There was scarcely a sportsman in the village who had not his story of some such disappearance of a dog whilst out shooting. The poor beast would become excited in pursuit of game, would dash headlong into a set of bushes and emerge no more. Then a moment’s examination would reveal the fatal cave. I am certain that I heard a good half-score of such histories. The cave, by the way, was not always fatal, for I heard of cases in which the dog had been known to find his way out of the underground labyrinth, and return home dreadfully thin and hungry, but otherwise undamaged. These cases gave me some faint hope for Schwartz, but as day after day went by the hope faded, and I made up my mind that I had seen the last of him. I was sorry to think so, for he had been very much a friend and a companion.
