This optical illusion evidently takes place because there are no points of comparison on these large s.p.a.ces. It was thus with the "Pilgrim,"

which decreased to the eye and seemed already much more distant than she really was.

Half an hour after leaving her, Captain Hull and his companions found themselves exactly to the leeward of the whale, so that the latter occupied an intermediate point between the ship and the boat.

So the moment had come to approach, while making as little noise as possible. It was not impossible for them to get beside the animal and harpoon it at good range, before its attention would be attracted.

"Row more slowly, boys," said Captain Hull, in a low voice.

"It seems to me," replied Howik, "that the gudgeon suspects something.

It breathes less violently than it did just now!"

"Silence! silence!" repeated Captain Hull.

Five minutes later the whale-boat was at a cable's length from the jubarte. A cable's length, a measure peculiar to the sea, comprises a length of one hundred and twenty fathoms, that is to say, two hundred meters.

The boatswain, standing aft, steered in such a manner as to approach the left side of the mammal, but avoiding, with the greatest care, pa.s.sing within reach of the formidable tail, a single blow of which would be enough to crush the boat.

At the prow Captain Hull, his legs a little apart to maintain his equilibrium, held the weapon with which he was going to give the first blow. They could count on his skill to fix that harpoon in the thick ma.s.s which emerged from the waters.

Near the captain, in a pail, was coiled the first of the five lines, firmly fastened to the harpoon, and to which they would successively join the other four if the whale plunged to great depths.

"Are we ready, boys?" murmured Captain Hull.

"Yes," replied Howik, grasping his oar firmly in his large hands.

"Alongside! alongside!"

The boatswain obeyed the order, and the whale-boat came within less than ten feet of the animal.

The latter no longer moved, and seemed asleep.

Whales thus surprised while asleep offer an easier prize, and it often happens that the first blow which is given wounds them mortally.

"This immovableness is quite astonishing!" thought Captain Hull. "The rascal ought not to be asleep, and nevertheless----there is something there!"

The boatswain thought the same, and he tried to see the opposite side of the animal.

But it was not the moment to reflect, but to attack.

Captain Hull, holding his harpoon by the middle of the handle, balanced it several times, to make sure of good aim, while he examined the jubarte's side. Then he threw it with all the strength of his arm.

"Back, back!" cried he at once.

And the sailors, pulling together, made the boat recoil rapidly, with the intention of prudently putting it in safety from the blows of the cetacean's tail.

But at that moment a cry from the boatswain made them understand why the whale was so extraordinarily motionless for so long a time on the surface of the sea.

"A young whale!" said he.

In fact, the jubarte, after having been struck by the harpoon, was almost entirely overturned on the side, thus discovering a young whale, which she was in process of suckling.

This circ.u.mstance, as Captain Hull well knew, would render the capture of the jubarte much more difficult. The mother was evidently going to defend herself with greater fury, as much for herself as to protect her "little one "--if, indeed, we can apply that epithet to an animal which did not measure less than twenty feet.

Meanwhile, the jubarte did not rush at the boat, as there was reason to fear, and there was no necessity, before taking flight, to quickly cut the line which connected the boat with the harpoon. On the contrary, and as generally happens, the whale, followed by the young one, dived, at first in a very oblique line; then rising again with an immense bound, she commenced to cleave the waters with extreme rapidity.

But before she had made her first plunge, Captain Hull and the boatswain, both standing, had had time to see her, and consequently to estimate her at her true value.

This jubarte was, in reality, a whale of the largest size. From the head to the tail, she measured at least eighty feet. Her skin, of a yellowish brown, was much varied with numerous spots of a darker brown.

It would indeed be a pity, after an attack so happily begun, to be under the necessity of abandoning so rich a prey.

The pursuit, or rather the towing, had commenced. The whale-boat, whose oars had been raised, darted like an arrow while swinging on the tops of the waves.

Howik kept it steady, notwithstanding those rapid and frightful oscillations. Captain Hull, his eye on his prey, did not cease making his eternal refrain:

"Be watchful, Howik, be watchful!"

And they could be sure that the boatswain's vigilance would not be at fault for an instant.

Meanwhile, as the whale-boat did not fly nearly as fast as the whale, the line of the harpoon spun out with such rapidity that it was to be feared that it would take fire in rubbing against the edge of the whale-boat. So Captain Hull took care to keep it damp, by filling with water the pail at the bottom of which the line was coiled.

All this time the jubarte did not seem inclined to stop her flight, nor willing to moderate it. The second line was then lashed to the end of the first, and it was not long before it was played out with the same velocity.

At the end of five minutes it was necessary to join on the third line, which ran off under the water.

The jubarte did not stop. The harpoon had evidently not penetrated into any vital part of the body. They could even observe, by the increased obliquity of the line, that the animal, instead of returning to the surface, was sinking into lower depths.

"The devil!" cried Captain Hull, "but that rascal will use up our five lines!"

"And lead us to a good distance from the 'Pilgrim,'" replied the boatswain.

"Nevertheless, she must return to the surface to breathe," replied Captain Hull. "She is not a fish, and she must have the provision of air like a common individual."

"She has held her breath to run better," said one of the sailors, laughing.

In fact, the line was unrolling all the time with equal rapidity.

To the third line, it was soon necessary to join the fourth, and that was not done without making the sailors somewhat anxious touching their future part of the prize.

"The devil! the devil!" murmured Captain Hull. "I have never seen anything like that! Devilish jubarte!"

Finally the fifth line had to be let out, and it was already half unrolled when it seemed to slacken.

"Good! good!" cried Captain Hull. "The line is less stiff. The jubarte is getting tired."

At that moment, the "Pilgrim" was more than five miles to the leeward of the whale-boat. Captain Hull, hoisting a flag at the end of a boat-hook, gave the signal to come nearer.

And almost at once, he could see that d.i.c.k Sand, aided by Tom and his companions, commenced to brace the yards in such a manner as to trim them close to the wind.
