The second voyage across the Atlantic was pleasant and speedy, but just after entering the Caribbean Sea a new danger threatened the adventurers, for early one morning they encountered a large Spanish frigate, which at once started in chase of them. Captain Phipps addressed his crew, telling them that if they permitted their ship to be captured they would be sent into the interior of the country as slaves, to drag out their lives in the silver-mines. He bade them fight bravely if they wished to enjoy home and freedom ever again. The superior speed of the Spaniard soon enabled that vessel to open fire on the _Algier Rose_, which so heartily returned the compliment that some of the foreigner’s spars were shot away, making her fall astern of her saucy enemy, who now succeeded in escaping. Without further trouble the treasure-hunters reached the island on whose treacherous coral reefs the silver-ship had been wrecked. Here the _Algier Rose_ was safely moored, and search commenced for the sunken wealth. The small boats were used to explore the reefs, and served as platforms from which the best swimmers in the crew would dive into the channels between the walls of coral on the lee side of the island, endeavoring to locate the spot where the galleon had been carried before she struck. As the water in these places seldom exceeded twenty feet in depth, the bottom would have been plainly visible from the boat had it not been for the continuous rippling and foaming of the surface water. Several weeks were passed in a vain pursuit, and at last, worn out and discouraged, the men positively refused to continue the work. By agreeing to abandon the enterprise and set sail for England at the end of another week, unless some success was met with, the Captain prevailed upon several of his seamen to aid him for that length of time.
