that at 320 feet this pressure equals that of 10 atmospheres, of 100 atmospheres at 3,200 feet, and of 1,000 atmospheres at 32,000 feet, that is, about 6 miles; which is equivalent to saying that if you could attain this depth in the ocean, each square three-eighths of an inch of the surface of your body would bear a pressure of 5,600 lb. Ah! my brave Ned, do you know how many square inches you carry on the surface of your body?"
"I have no idea, Mr. Aronnax."
"About 6,500; and as in reality the atmospheric pressure is about 15 lb. to the square inch, your 6,500 square inches bear at this moment a pressure of 97,500 lb."
"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 neutralise 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 lb.; 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 lb.—that is to say, that you would be flattened as if you had been drawn from the plates of a 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 organisation to withstand such pressure!"
"Why!" exclaimed Ned Land, "they must be made of iron plates eight inches thick, like the armoured 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?"
CHAPTER V
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 favour.
The frigate skirted the south-east coast of America with great rapidity. The 3rd 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 lost 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 towards the north-west, 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.
I myself, for whom money had no charms, was not the least attentive on board. Giving but few minutes to my meals, but a few hours to sleep, indifferent to either rain or sunshine, I did not leave the poop of the vessel. Now leaning on the netting of the forecastle, now on the taffrail, I devoured with eagerness the soft foam which whitened the sea as far as the eye could reach; and how often have I shared the emotion of the majority of the crew, when some capricious whale raised its black back above the waves! The poop of the vessel was crowded on a moment. The cabins poured forth a torrent of sailors and officers, each with heaving breast and troubled eye watching the course of the cetacean. I looked and looked till I was nearly blind, whilst Conseil kept repeating in a calm voice:
"If, sir, you would not squint so much, you would see better!"
But vain excitement! The Abraham Lincoln checked its speed and made for the animal signalled, a simple whale, or common cachalot, which soon disappeared amidst a storm of abuse.
But the weather was good. The voyage was being accomplished under the most favourable auspices. It was then the bad season in Australia, the July of that zone corresponding to our January in Europe, but the sea was beautiful and easily scanned round a vast circumference.
The 20th of July, the tropic of Capricorn was cut by 105d of longitude, and the 27th of the same month we crossed the Equator on the 110th meridian. This passed, the frigate took a more decided westerly direction, and scoured the central waters of the Pacific. Commander Farragut thought, and with reason, that it was better to remain in deep water, and keep clear of continents or islands, which the beast itself seemed to shun (perhaps because there was not enough water for him! suggested the greater part of the crew). The frigate passed at some distance from the Marquesas and the Sandwich Islands, crossed the tropic of Cancer, and made for the China Seas. We were on the theatre of the last diversions of the monster: and, to say truth, we no longer LIVED on board. The entire ship's crew were undergoing a nervous excitement, of which I can give no idea: they could not eat, they could not sleep—twenty times a day, a misconception or an optical illusion of some sailor seated on the taffrail, would cause dreadful perspirations, and these emotions, twenty times repeated, kept us in a state of excitement so violent that a reaction was unavoidable.
And truly, reaction soon showed itself. For three months, during which a day seemed an age, the Abraham Lincoln furrowed all the waters of the Northern Pacific, running at whales, making sharp deviations from her course, veering suddenly from one tack to another, stopping suddenly, putting on steam, and backing ever and anon at the risk of deranging her machinery, and not one point of the Japanese or American coast was left unexplored.
The warmest partisans of the enterprise now became its most ardent detractors. Reaction mounted from the crew to the captain himself, and certainly, had it not been for the resolute determination on the part of Captain Farragut, the frigate would have headed due southward. This useless search could not last much longer. The Abraham Lincoln had nothing to reproach herself with, she had done her best to succeed. Never had an American ship's crew shown more zeal or patience; its failure could
