Would she not content herself with only surveying the coast, and stand out to sea again without landing her crew? They would know this in an hour. The colonists could do nothing but wait.

Cyrus Harding had not seen the suspected vessel hoist the black flag without deep anxiety. Was it not a direct menace against the work which he and his companions had till now conducted so successfully? Had these pirates--for the sailors of the brig could be nothing else--already visited the island, since on approaching it they had hoisted their colors. Had they formerly invaded it, so that certain unaccountable peculiarities might be explained in this way? Did there exist in the as yet unexplored parts some accomplice ready to enter into communication with them?

To all these questions which he mentally asked himself, Harding knew not what to reply; but he felt that the safety of the colony could not but be seriously threatened by the arrival of the brig.

However, he and his companions were determined to fight to the last gasp. It would have been very important to know if the pirates were numerous and better armed than the colonists. But how was this information to he obtained?

Night fell. The new moon had disappeared. Profound darkness enveloped the island and the sea. No light could pierce through the heavy piles of clouds on the horizon. The wind had died away completely with the twilight. Not a leaf rustled on the trees, not a ripple murmured on the shore. Nothing could be seen of the ship, all her lights being extinguished, and if she was still in sight of the island, her whereabouts could not be discovered.

"Well! who knows?" said Pencroft. "Perhaps that cursed craft will stand off during the night, and we shall see nothing of her at daybreak."

As if in reply to the sailor's observation, a bright light flashed in the darkness, and a cannon-shot was heard.

The vessel was still there and had guns on board.

Six seconds elapsed between the flash and the report.

Therefore the brig was about a mile and a quarter from the coast.

At the same time, the chains were heard rattling through the hawse-holes.

The vessel had just anchored in sight of Granite House!

Chapter 2

There was no longer any doubt as to the pirates' intentions. They had dropped anchor at a short distance from the island, and it was evident that the next day by means of their boats they purposed to land on the beach!

Cyrus Harding and his companions were ready to act, but, determined though they were, they must not forget to be prudent. Perhaps their presence might still be concealed in the event of the pirates contenting themselves with landing on the shore without examining the interior of the island. It might be, indeed, that their only intention was to obtain fresh water from the Mercy, and it was not impossible that the bridge, thrown across a mile and a half from the mouth, and the manufactory at the Chimneys might escape their notice.

But why was that flag hoisted at the brig's peak? What was that shot fired for? Pure bravado doubtless, unless it was a sign of the act of taking possession. Harding knew now that the vessel was well armed. And what had the colonists of Lincoln Island to reply to the pirates' guns? A few muskets only.

"However," observed Cyrus Harding, "here we are in an impregnable position. The enemy cannot discover the mouth of the outlet, now that it is hidden under reeds and grass, and consequently it would be impossible for them to penetrate into Granite House."

"But our plantations, our poultry-yard, our corral, all, everything!" exclaimed Pencroft, stamping his foot. "They may spoil everything, destroy everything in a few hours!"

"Everything, Pencroft," answered Harding, "and we have no means of preventing them."

"Are they numerous? that is the question," said the reporter. "If they are not more than a dozen, we shall be able to stop them, but forty, fifty, more perhaps!"

"Captain Harding," then said Ayrton, advancing towards the engineer, "will you give me leave?"

"For what, my friend?"

"To go to that vessel to find out the strength of her crew."

"But Ayrton--" answered the engineer, hesitating, "you will risk your life--"

"Why not, sir?"

"That is more than your duty."

"I have more than my duty to do," replied Ayrton.
