Once more we ate and drank, and as we did so an idea occurred to me.
“How is it,” said I, “that the air in this place keeps fresh? It is thick and heavy, but it is perfectly fresh.”
“Great heavens!” said Good, starting up, “I never thought of that. It can’t come through the stone door, for it’s air-tight, if ever a door was. It must come from somewhere. If there were no current of air in the place we should have been stifled or poisoned when we first came in. Let us have a look.”
It was wonderful what a change this mere spark of hope wrought in us. In a moment we were all three groping about on our hands and knees, feeling for the slightest indication of a draught. Presently my ardour received a check. I put my hand on something cold. It was dead Foulata’s face.
For an hour or more we went on feeling about, till at last Sir Henry and I gave it up in despair, having been considerably hurt by constantly knocking our heads against tusks, chests, and the sides of the chamber. But Good still persevered, saying, with an approach to cheerfulness, that it was better than doing nothing.
“I say, you fellows,” he said presently, in a constrained sort of voice, “come here.”
Needless to say we scrambled towards him quickly enough.
“Quatermain, put your hand here where mine is. Now, do you feel anything?”
“I think I feel air coming up.”
“Now listen.” He rose and stamped upon the place, and a flame of hope shot up in our hearts. It rang hollow.
