"While looking for nests, thirty-five years ago. I was one day on the rock, and I often noticed, coming in and out of this nook, a _grand duke_ and its mate, two magnificent birds, the head as large as my fist, and the wings six feet across. I heard the cry of their little ones, and I said to myself: 'They are near the cavern, at the end of the terrace. If I could take just one turn a little beyond the gap, I should have them!' By means of looking and leaning over, I managed to see the corner of a step just above the precipice. I found a strong holly tree beside it. I grasped the tree, put out my leg, and there I was! What a fight, Hullin! the old bird and his mate were ready to tear my eyes out. Luckily, it was daylight. They flew at me like fighting-cocks, pecking at me, and screaming horribly all the while; but the sun dazzled them. I kicked them with all my might. At last they fell down stunned over the top of that old fir tree down below there; and all the jays round about, the thrushes, the greenfinches, the tomtits, kept flying round about them till night-time, to strip them of their feathers. You can't imagine, Jean-Claude, the heap of bones, of skins of rats, leverets, of skeletons of all sorts, that I found in this nook. It was a regular pest-house. I lost no time in clearing it all out, and discovered this narrow passage. I must tell you there were two young ones. The first thing I did was to wring their necks, and stuff them into my bag; that done, I entered very quietly, and you shall see what I found. Come on." They then crept along beneath the narrow and low vault formed by enormous blocks of red stone, and through which the lantern they carried cast a flickering light. At the end of about thirty feet, a vast cavern of circular form, hollowed out of the solid rock, appeared before Hullin. At the bottom were ranged in pyramids about fifty little barrels, and at the sides a great number of bars of lead and bags of tobacco, with the strong odour of which the air was filled. Marc left his lantern at the entrance of the vault, and now stood looking proudly on his den, while a smile curled his lips.
