"How do you like this, Nina?" said Ben Zoof.
"_Va bene!_" replied the child. "We are only living in the cellars instead of upon the ground floor."
"We will try and make ourselves comfortable," said the orderly.
"Oh yes, we will be happy here," rejoined the child; "it is nice and warm."
Although they were as careful as they could to conceal their misgivings from the rest, Servadac and his two friends could not regard their present situation without distrust. When alone, they would frequently ask each other what would become of them all, if the volcanic heat should really be subsiding, or if some unexpected perturbation should retard the course of the comet, and compel them to an indefinitely prolonged residence in their grim abode. It was scarcely likely that the comet could supply the fuel of which ere long they would be in urgent need. Who could expect to find coal in the bowels of Gallia,--coal, which is the residuum of ancient forests mineralized by the lapse of ages? Would not the lava-cinders exhumed from the extinct volcano be their last poor resource?
"Keep up your spirits, my friends," said Servadac; "we have plenty of time before us at present. Let us hope that as fresh difficulties arise, fresh ways of escape will open. Never despair!"
"True," said the count; "it is an old saying that 'Necessity is the mother of invention.' Besides, I should think it very unlikely that the internal heat will fail us now before the summer."
The lieutenant declared that he entertained the same hope. As the reason of his opinion he alleged that the combustion of the eruptive matter was most probably of quite recent origin, because the comet before its collision with the earth had possessed no atmosphere, and that consequently no oxygen could have penetrated to its interior.
"Most likely you are right," replied the count; "and so far from dreading a failure of the internal heat, I am not quite sure that we may not be exposed to a more terrible calamity still?"
"The calamity of the eruption breaking out suddenly again, and taking us by surprise."
"Heavens!" cried the captain, "we will not think of that."
"The outbreak may happen again," said the lieutenant, calmly; "but it will be our fault, our own lack of vigilance, if we are taken by surprise." And so the conversation dropped.
