Cyrus Harding had clearly represented their situation, although he spoke in the calmest voice, as if it was a question of directing a piece of work and not ordering a battle.  His companions approved these arrangements without even uttering a word.  There was nothing more to be done but for each to take his place before the fog should be completely dissipated.  Neb and Pencroft immediately ascended to Granite House and brought back a sufficient quantity of ammunition.  Gideon Spilett and Ayrton, both very good marksmen, were armed with the two rifles, which carried nearly a mile.  The four other muskets were divided among Harding, Neb, Pencroft, and Herbert.

The posts were arranged in the following manner:—­

Cyrus Harding and Herbert remained in ambush at the Chimneys, thus commanding the shore to the foot of Granite House.

Gideon Spilett and Neb crouched among the rocks at the mouth of the Mercy, from which the drawbridges had been raised, so as to prevent any one from crossing in a boat or landing on the opposite shore.

As to Ayrton and Pencroft, they shoved off in the boat, and prepared to cross the channel and to take up two separate stations on the islet.  In this way, shots being fired from four different points at once, the convicts would be led to believe that the island was both largely peopled and strongly defended.

In the event of a landing being effected without their having been able to prevent it, and also if they saw that they were on the point of being cut off by the brig’s boat, Ayrton and Pencroft were to return in their boat to the shore and proceed towards the threatened spot.

Before starting to occupy their posts, the colonists for the last time wrung each other’s hands.

Pencroft succeeded in controlling himself sufficiently to suppress his emotion when he embraced Herbert, his boy! and then they separated.

In a few moments Harding and Herbert on one side, the reporter and Neb on the other, had disappeared behind the rocks, and five minutes later Ayrton and Pencroft, having without difficulty crossed the channel, disembarked on the islet and concealed themselves in the clefts of its eastern shore.

None of them could have been seen, for they themselves could scarcely distinguish the brig in the fog.

It was half-past six in the morning.

Soon the fog began to clear away, and the topmasts of the brig issued from the vapor.  For some minutes great masses rolled over the surface of the sea, then a breeze sprang up, which rapidly dispelled the mist.

The “Speedy” now appeared in full view, with a spring on her cable, her head to the north, presenting her larboard side to the island.  Just as Harding had calculated, she was not more than a mile and a quarter from the coast.

The sinister black flag floated from the peak.

The engineer, with his telescope, could see that the four guns on board were pointed at the island.  They were evidently ready to fire at a moment’s notice.
