But, as he had explained to Kennedy, it was now impossible for him to descend, except by releasing a quantity of gas proportionate to his loss of ballast at the time when he had rescued the missionary. He therefore opened the valve of the outside balloon. The hydrogen escaped, and the _Victoria_ quietly descended into the ravine. As soon as the car touched the ground, the doctor shut the valve. Joe leaped out, holding on the while to the rim of the car with one hand, and with the other gathering up a quantity of stones equal to his own weight. He could then use both hands, and had soon heaped into the car more than five hundred pounds of stones, which enabled both the doctor and Kennedy, in their turn, to get out. Thus the _Victoria_ found herself balanced, and her ascensional force insufficient to raise her. Moreover, it was not necessary to gather many of these stones, for the blocks were extremely heavy, so much so, indeed, that the doctor’s attention was attracted by the circumstance. The soil, in fact, was bestrewn with quartz and porphyritic rocks. “This is a singular discovery!” said the doctor, mentally. In the mean while, Kennedy and Joe had strolled away a few paces, looking up a proper spot for the grave. The heat was extreme in this ravine, shut in as it was like a sort of furnace. The noonday sun poured down its rays perpendicularly into it. The first thing to be done was to clear the surface of the fragments of rock that encumbered it, and then a quite deep grave had to be dug, so that the wild animals should not be able to disinter the corpse. The body of the martyred missionary was then solemnly placed in it. The earth was thrown in over his remains, and above it masses of rock were deposited, in rude resemblance to a tomb. The doctor, however, remained motionless, and lost in his reflections. He did not even heed the call of his companions, nor did he return with them to seek a shelter from the heat of the day. “What are you thinking about, doctor?” asked Kennedy. “About a singular freak of Nature, a curious effect of chance. Do you know, now, in what kind of soil that man of self-denial, that poor one in spirit, has just been buried?” “No! what do you mean, doctor?” “That priest, who took the oath of perpetual poverty, now reposes in a gold-mine!” “A gold-mine!” exclaimed Kennedy and Joe in one breath. “Yes, a gold-mine,” said the doctor, quietly. “Those blocks which you are trampling under foot, like worthless stones, contain gold-ore of great purity.” “Impossible! impossible!” repeated Joe. “You would not have to look long among those fissures of slaty schist without finding peptites of considerable value.” Joe at once rushed like a crazy man among the scattered fragments, and Kennedy was not long in following his example. “Keep cool, Joe,” said his master. “Why, doctor, you speak of the thing quite at your ease.” “What! a philosopher of your mettle—” “Ah, master, no philosophy holds good in this case!”
