“A simple question to ask you, sir,” replied the Canadian.
“Speak, Ned.”
“How many men are there on board the Nautilus, do you think?”
“I cannot tell, my friend.”
“I should say that its working does not require a large crew.”
“Certainly, under existing conditions, ten men, at the most, ought to be enough.”
“Well, why should there be any more?”
“Why?” I replied, looking fixedly at Ned Land, whose meaning was easy to guess. “Because,” I added, “if my surmises are correct, and if I have well understood the captain’s existence, the Nautilus is not only a vessel, it is also a place of refuge for those who, like its commander, have broken every tie upon earth.”
“Perhaps so,” said Conseil; “but, in any case, the Nautilus can only contain a certain number of men. Could not you, sir, estimate their maximum?”
“How, Conseil?”
“By calculation; given the size of the vessel, which you know, sir, and consequently the quantity of air it contains, knowing also how much each man expends at a breath, and comparing these results with the fact that the Nautilus is obliged to go to the surface every twenty-four hours.”
Conseil had not finished the sentence before I saw what he was driving at.
“I understand,” said I; “but that calculation, though simple enough, can give but a very uncertain result.”
“Never mind,” said Ned Land urgently.
“Here it is, then,” said I. “In one hour each man consumes the oxygen contained in twenty gallons of air; and in twenty-four, that contained in 480 gallons. We must, therefore, find how many times 480 gallons of air the Nautilus contains.”
“Just so,” said Conseil.
“Or,” I continued, “the size of the Nautilus being 1,500 tons, and one ton holding 200 gallons, it contains 300,000 gallons of air, which, divided by 480, gives a quotient of 625. Which means to say, strictly speaking, that the air contained in the Nautilus would suffice for 625 men for twenty-four hours.”
“Six hundred and twenty-five!” repeated Ned.
“But remember, that all of us, passengers, sailors, and officers included, would not form a tenth part of that number.”
“Still too many for three men,” murmured Conseil.
The Canadian shook his head, passed his hand across his forehead, and left the room without answering.
“Will you allow me to make one observation, sir?” said Conseil. “Poor Ned is longing for everything that he cannot have. His past life is always present to him; everything that we are forbidden he regrets. His head is full of old recollections. And we must understand him. What has he to do here? Nothing; he is not learned like you, sir; and has not the same taste for the beauties of the sea that we have. He would risk everything to be able to go once more into a tavern in his own country.”
Certainly the monotony on board must seem intolerable to the Canadian, accustomed as he was to a life of liberty and activity. Events were rare which could rouse him to any show of spirit; but that day an event did happen which recalled the bright days of the harpooner. About eleven in the morning, being on the surface of the ocean, the Nautilus fell in with a troop of whales—an encounter which did not astonish me, knowing that these creatures, hunted to the death, had taken refuge in high latitudes.
We were seated on the platform, with a quiet sea. The month of October in those latitudes gave us some lovely autumnal days. It was the Canadian—he could not be mistaken—who signaled a whale on the eastern horizon. Looking attentively one might see its black back rise and fall with the waves five miles from the Nautilus.
“Ah!” exclaimed Ned Land, “if I was on board a whaler now, such a meeting would give me pleasure. It is one of large size. See with what strength its blow-holes throw up columns of air and steam! Confound it, why am I bound to these steel plates?”
“What, Ned,” said I, “you have not forgotten your old ideas of fishing!”
“Can a whale-fisher ever forget his old trade, sir? Can he ever tire of the emotions caused by such a chase?”
