“Well,” cried the Professor, “as we have no guns we cannot hunt, that’s all.”

“Yes, but how about the instruments?”

“Here is the aneroid, the most useful of all, and for which I would have given all the others. By means of it I can calculate the depth and know when we have reached the centre; without it we might very likely go beyond, and come out at the antipodes!”

Such high spirits as these were rather too strong.

“But where is the compass?” I asked.

“Here it is, upon this rock, in perfect condition, as well as the thermometers and the chronometer. The hunter is a splendid fellow.”

There was no denying it. We had all our instruments. As for tools and appliances, there they all lay on the ground⁠—ladders, ropes, picks, spades, etc.
