And, again, although a fair amount of provisions had been set aside to victual the boat, nothing had yet been done to hide them in the cave. Neither had any of the people in the secret been able to obtain a receptacle of any description to carry water, and fresh water was indispensable for the voyage.

Nor had the cave been explored. Branscombe had collected enough rope to make a three-inch hawser of two hundred and fifty feet in length, more than sufficient to reach from the top of the cliff to the beach, but the actual descent had not yet been attempted.

Clearly a stupendous task confronted Burgoyne. Much had been accomplished, but more remained to be done in secrecy and with dispatch.

On the following morning Burgoyne rejoined his working-party. Fernando, the half-caste who had succeeded Black Strogoff as overseer-in-chief to the prisoners, nodded and made some remark. The words being Spanish, Alwyn failed to understand them, but evidently they were of a complimentary nature.

Before the working-party arrived upon the scene of operations, one of the men who had done a good deal of voyaging on the South American coast explained that Señor Fernando was delighted that Perez —Burgoyne's late opponent—had been vanquished. There was no love lost between Fernando and the late leading gun-layer of the Malfilio.

The work of unloading the Donibristle's cargo had been completed, but most of her stores were taken on board the Kittiwake. It was obviously the intention of the pirates to keep the latter vessel in a seaworthy condition, since she had not been stripped as in the case of the other prizes. In addition, a wireless operator, a German with a knowledge of four or five languages, was constantly on duty on board the Kittiwake. He merely "caught" and reported radios from vessels within range of the apparatus, making no attempt to transmit, lest the source of origin might be located.

Instead of being ordered to man the crane, Burgoyne's party were marched through the tunnel down to the beach. Here they "stood easy", while a number of the Malfilio's crew launched and loaded a boat, placing a number of explosive charges into the stern-sheets. The pirates then pushed off and made for the Donibristle.

Presently the reason for the unusual "stand easy" became apparent. Pablo Henriques, being unable to give intelligible orders in English, had reluctantly been compelled to bring Black Strogoff upon the scene.

For the next three hours the captives were kept hard at it, laying out anchors in the centre of the deep channel, until a continuous line of warping buoys was laid from the Donibristle's berth to the entrance to the enclosed harbour. It was heavy and exacting work handling those anchors, weighing anything between five and nine hundredweight. A hitch in the operations, or the slightest lubberly work, might easily result in the capsizing of one of the boats, and more than likely the loss of several of her crew.

This task completed, the men expected a respite. They got none. Instead, Black Strogoff ordered them to take other anchors and place them on either side of the narrow channel turning southward between the island and the long narrow mass of rock that protected the entrance to the harbour.
