The next scourge of the Spaniard in these seas was Pierre François, a native of Dunkirk, whose combinative, far-seeing genius and dauntless heart soon raised him above the level of the mere footpads of the ocean. His little brigantine, with a picked crew of twenty-six men--hunters by sea and land--cruised generally about the Cape de la Vela, waiting for merchant ships on their way from Maracaibo to Campeachy. Pierre had now been a long time afloat and taken no prize, the usual prelude to great enterprises amongst these men, who defied all dangers and all enemies. The provisions were running short, the boat was leaky, the captain moody and silent, and the crew half mutinous. To return empty-handed to Tortuga was to be a butt for every sneerer, a victim to unrelenting creditors; to the men beggary, to Pierre a loss of fame and all future promotion. But, there being a perfect equality in these boats, the crews seldom rose in open rebellion; and as every one had a voice in the proposal of a scheme, there was no one to rail at if the scheme failed. At last, amid this suspense, more tedious than a tropic calm, one more daring or more far-seeing than the rest stood up and suggested a visit to the pearl-fishings at the Rivière de la Hache. History, always drowsy at critical periods, does not say if François was the proposer of this scheme or not. We may be sure he was a sturdy seconder, and that the plan was carried amid wild cheering and waving of hats and guns and swords enough to scare the sharks floating hungrily round the boat, and frighten the glittering flying-fish back into the sea. These Rancheria fishings were at a rich bank of pearl to which the people of Carthagena sent annually twelve vessels, with a man-of-war convoy, generally a Spanish armadilla with a crew of 200 men, and carrying twenty-four pieces of cannon. Every vessel had two or three Negro slaves on board, who dived for the pearls. These men seldom lived long, and were frequently ruptured by the exertion of holding breath a quarter of an hour below the waves. The time for diving was from October till May, when the north winds were lulled and the sea calm.
