as regards practical effect, the transit described by the ball ought to be as extended as possible, and this tension could only be obtained under the condition that the projectile should be impelled with a very great initial velocity.
“Now,” said Harding to his companions, “the initial velocity is in proportion to the quantity of powder used. In the fabrication of these pieces, everything depends on employing a metal with the highest possible power of resistance, and steel is incontestably that metal of all others which resists the best. I have, therefore, reason to believe that our guns will bear without risk the expansion of the pyroxile gas, and will give excellent results.”
“We shall be a great deal more certain of that when we have tried them!” answered Pencroft.
It is unnecessary to say that the four cannons were in perfect order. Since they had been taken from the water, the sailor had bestowed great care upon them. How many hours he had spent, in rubbing, greasing, and polishing them, and in cleaning the mechanism! And now the pieces were as brilliant as if they had been on board a frigate of the United States’ Navy.
On this day, therefore, in presence of all the members of the colony, including Master Jup and Top, the four cannon were successively tried. They were charged with pyroxile, taking into consideration its explosive power, which, as has been said, is four times that of ordinary powder: the projectile to be fired was cylindro-conic.
Pencroft, holding the end of the quick-match, stood ready to fire.
At Harding’s signal, he fired. The shot, passing over the islet, fell into the sea at a distance which could not be calculated with exactitude.
The second gun was pointed at the rocks at the end of Flotsam Point, and the shot, striking a sharp rock nearly three miles from Granite House, made it fly into splinters. It was Herbert who had pointed this gun and fired it, and very proud he was of his first shot. Pencroft only was prouder than he! Such a shot, the honour of which belonged to his dear boy.
The third shot, aimed this time at the downs forming the upper side of Union Bay, struck the sand at a distance of four miles, then having ricocheted, was lost in the sea in a cloud of spray.
For the fourth piece Cyrus Harding slightly increased the charge, so as to try its extreme range. Then, all standing aside for fear of its bursting, the match was lighted by means of a long cord.
A tremendous report was heard, but the piece had held good, and the colonists rushing to the windows, saw the shot graze the rocks of Mandible Cape, nearly five miles from Granite House, and disappear in Shark Gulf.
“Well, captain,” exclaimed Pencroft, whose cheers might have rivalled the reports themselves, “what do you say of our battery? All the pirates in the Pacific have only to present themselves before Granite House! Not one can land there now without our permission!”
“Believe me, Pencroft,” replied the engineer, “it would be better not to have to make the experiment.”
“Well,” said the sailor, “what ought to be done with regard to those six villains who are roaming about the island? Are we to leave them to overrun our forests, our fields, our plantations. These pirates are regular jaguars, and it seems to me we ought not to hesitate to treat them as such! What do you think, Ayrton?” added Pencroft, turning to his companion.
Ayrton hesitated at first to reply, and Cyrus Harding regretted that Pencroft had so thoughtlessly put this question. And he was much moved when Ayrton replied in a humble tone—
“I have been one of those jaguars, Mr Pencroft. I have no right to speak.”
And with a slow step he walked away.
Pencroft understood.
“What a brute I am!” he exclaimed. “Poor Ayrton! He has as much right to speak here as any one!”
“Yes,” said Gideon Spilett, “but his reserve does him honour, and it is right to respect the feeling which he has about his sad past.”
“Certainly, Mr Spilett,” answered the sailor, “and there is no fear of my doing so again. I would rather bite my tongue off than cause Ayrton any pain! But to return to the question. It seems to me that these ruffians have no right to any pity, and that we ought to rid the island of them as soon as possible.”
“Is that your opinion, Pencroft?” asked the engineer.
“Quite my opinion.”
“And before hunting them mercilessly, you would not wait until they had committed some fresh act of hostility against us?”
“Isn’t what they have done already enough?” asked Pencroft, who did not understand these scruples.
“They may adopt other sentiments!” said Harding, “and perhaps repent.”
“They repent!” exclaimed the sailor, shrugging his shoulders.
“Pencroft, think of Ayrton!” said Herbert, taking the sailor’s hand. “He became an honest man again!”
Pencroft looked at his companions one after the other. He had never thought of his proposal being met with any objection. His rough nature could not allow that they ought to come to terms with the rascals who had landed on the island with Bob Harvey’s accomplices, the murderers of the crew of the Speedy; and he looked upon them as wild beasts which ought to be destroyed without delay and without remorse.
“Come!” said he. “Everybody is against me! You wish to be generous to those villains! Very well; I hope we mayn’t repent it!”
“What danger shall we run,” said Herbert, “if we take care to be always on our guard!”
“Hum!” observed the reporter, who had not given any decided opinion. “They are six and well-armed. If they each lay hid in a corner, and each fired at one of us, they would soon be masters of the colony!”
“Why have they not done so?” said Herbert. “No doubt because it was not their interest to do it. Besides, we are six also.”
“Well, well!” replied Pencroft, whom no reasoning could have convinced. “Let us leave these good people to do what they like, and don’t think anything more about them!”
“Come, Pencroft,” said Neb, “don’t make yourself out so bad as all that! Suppose one of these unfortunate men were here before you, within good range of your gun, you would not fire.”
“I would fire on him as I would on a mad dog, Neb,” replied Pencroft coldly.
“Pencroft,” said the engineer, “you have always shown much deference to my advice; will you, in this matter, yield to me?”
“I will do as you please, Captain Harding,” answered the sailor, who was not at all convinced.
“Very well, wait, and we will not attack them unless we are attacked first.”
Thus their behaviour towards the pirates was agreed upon, although Pencroft augured nothing good from it. They were not to attack them, but were to be on their guard. After all, the island
