“I have no idea, Mr. Aronnax.”
“About 6,500; and, as in reality the atmospheric pressure is about 15 lbs. to the square inch, your 6,500 square inches bear at this moment a pressure of 97,500 lbs.”
“Without my perceiving it?”
“Without your perceiving it. And if you are not crushed by such a pressure, it is because the air penetrates the interior of your body with equal pressure. Hence perfect equilibrium between the interior and exterior pressure, which thus neutralize each other, and which allows you to bear it without inconvenience. But in the water it is another thing.”
“Yes, I understand,” replied Ned, becoming more attentive; “because the water surrounds me, but does not penetrate.”
“Precisely, Ned; so that at 32 feet beneath the surface of the sea you would undergo a pressure of 97,500 lbs.; at 320 feet, ten times that pressure; at 3,200 feet, a hundred times that pressure; lastly, at 32,000 feet, a thousand times that pressure would be 97,500,000 lbs.—that is to say, that you would be flattened as if you had been drawn from the plates of an hydraulic machine!”
“The devil!” exclaimed Ned.
“Very well, my worthy harpooner, if some vertebrate, several hundred yards long, and large in proportion, can maintain itself in such depths—of those whose surface is represented by millions of square inches, that is by tens of millions of pounds, we must estimate the pressure they undergo. Consider, then, what must be the resistance of their bony structure, and the strength of their organization to withstand such pressure!”
“Why!” exclaimed Ned Land. “They must be made of iron plates eight inches thick, like the armored frigates.”
“As you say, Ned. And think what destruction such a mass would cause if hurled with the speed of an express train against the hull of a vessel.”
“Yes—certainly—perhaps,” replied the Canadian, shaken by these figures, but not yet willing to give in.
“Well, have I convinced you?”
“You have convinced me of one thing, sir, which is, that if such animals do exist at the bottom of the seas, they must necessarily be as strong as you say.”
“But if they do not exist, mine obstinate harpooner, how explain the accident to the Scotia?”
At a Venture
The voyage of the Abraham Lincoln was for a long time marked by no special incident. But one circumstance happened which showed the wonderful dexterity of Ned Land, and proved what confidence we might place in him.
The 30th of June, the frigate spoke some American whalers, from whom we learned that they knew nothing about the narwhal. But one of them, the captain of the Monroe, knowing that Ned Land had shipped on board the Abraham Lincoln, begged for his help in chasing a whale they had in sight. Commander Farragut, desirous of seeing Ned Land at work, gave him permission to go on board the Monroe. And fate served our Canadian so well that, instead of one whale, he harpooned two with a double blow, striking one straight to the heart and catching the other after some minutes’ pursuit.
Decidedly, if the monster ever had to do with Ned Land’s harpoon, I would not bet in its favor.
The frigate skirted the southeast coast of America with great rapidity. The 3d of July we were at the opening of the Straits of Magellan, level with Cape Vierges. But Commander Farragut would not take a tortuous passage, but doubled Cape Horn.
The ship’s crew agreed with him. And certainly it was possible that they might meet the narwhal in this narrow pass. Many of the sailors affirmed that the monster could not pass there, “that he was too big for that!”
The 6th of July, about three o’clock in the afternoon, the Abraham Lincoln, at fifteen miles to the south, doubled the solitary island, this last rock at the extremity of the American continent to which some Dutch sailors gave the name of their native town, Cape Horn. The course was taken toward the northwest, and the next day the screw of the frigate was at last beating the waters of the Pacific.
“Keep your eyes open!” called out the sailors.
And they were opened widely. Both eyes and glasses, a little dazzled, it is true, by the prospect of two thousand dollars, had not an instant’s repose. Day and night they watched the surface of the ocean, and even nyctalopes, whose faculty of seeing in the darkness multiplies their chances a hundredfold, would have had enough to do to gain the prize.
