“But you will not fire another unless you are troubled with sharks?” queried the captain.
“I intend to fire a canister exactly beneath where we stand,” said Dutch, “so as to sweep away the growth and sand and shingle that have been accumulating for the last two hundred years. One of those charges will do more in an instant than the men could do under water in a week.”
He raised his eyes as he spoke, and found that the mulatto was listening intently to every word, but with his eyes half-closed and a bitter look upon his face.
By this time the water was fast growing clear, and the change beneath the schooner was remarkable. The canister of dynamite must have sunk nearly to the bottom before it was exploded, and so great was the lateral sweep of the concussion that the seaweed seemed to have been levelled down in one direction, like a plantation after the passage of a hurricane; and grim and stark stood up now a series of dark stumps, the relics of the timbers of the ill-fated Spanish galleon, if such it really proved to be. Some of these were black and nearly level with the sand; some were worn to a point by the attrition of the current; but there, plainly enough now, could be traced out in timbers the shape of the vessel; but not for long, since the weed began once more to float into its normal position; but enough was known now, and Oakum took a fresh plug of tobacco as he said to Rasp—
“There, old ’un, your work’s cut out for some time to come.”
No time was lost. A couple of dynamite canisters were lowered down in the most suitable spots where the sand and weed seemed to be thickest, and Mr Parkley held one thin coil of wire, and Dutch and another, at opposite sides of the schooner, the kedge hawsers were buoyed and slipped; and, as the vessel slowly went with the current, the wire was payed out till the schooner had swung right round, and was riding by the anchor from her bows, and eighty or ninety yards away from the sunken wreck. The wire was sufficiently long to render the use of the boat unnecessary, and all being ready the battery was once more brought into use, the wires being connected, and this time the water surged up as from some volcanic eruption, a great wave ran towards the schooner, which rode over it easily, and it passed on towards the shore, washing right up again amongst the trees.
The men went to work with a will, getting ropes to the buoys, hauling upon them, and gradually working the schooner back, and mooring her in her old position; but it was a good hour later before the water was once more clear, and they gazed down upon quite a different scene from that of the morning.
So effective had been the force of the explosion that sand, weeds, small rocks and shingles, had been completely swept away, and lay at a distance, while the interior of the old wreck seemed to have been scooped right out.
The most careful search with the eye, though, failed to show any traces of that which they sought, and as evening was now fast drawing on, any further investigations were left till the following day.
