Where did they come from and what gave rise to the ocean nuisances? About the time named Spain was the mistress of most of the South American countries. When she discovered America through Columbus, and for a long period afterward, she was one of the greatest maritime nations in the world. Like England at the present time, she had colonies in all parts of the globe, and had she not been so cruel and unwise in the treatment of her dependencies, would still have retained a great deal of her former greatness and power; but she is one of the few nations that never learn from experience, and a short time after our second war with Great Britain her South American colonies began revolting against her, and one by one they gained their independence. Among the most powerful of the rebelling provinces were Buenos Ayres and Venezuela; and, taking lesson from the success of our privateers, they sent out many swift sailing, well-armed vessels to prey upon Spanish commerce. They did their work so effectively that by and by they extended their attacks to the vessels of all nations. Nothing being done for a time to check them, they grew rapidly in numbers and audacity, until, as has been stated, the West Indies swarmed with the pests. The men living along the coast found buccaneering so profitable that they gave up their peaceful pursuits and became free-booters of the sea. Like the Spaniards themselves, they were ferocious, and generally murdered the crews of the captured vessels and then divided the plunder among themselves. Seeing that something must be done to check these intolerable outrages, our Government gave the task, in 1819, to Oliver Hazard Perry, the hero of Lake Erie. His work was more difficult than would be supposed, for, in addition to destroying the pirates, he had to avoid offending the countries named, with whom we wished to maintain friendly relations. They sent out regular cruisers that had the same right to prey upon Spanish commerce that our privateers had to attack English ships when we were at war with their country. Some of these cruisers secretly engaged in piracy; many that flew the black flag, in the presence of those who could not defend themselves, claimed to be authorized privateers at other times and carried forged commissions. They were treacherous, cruel and merciless to the last degree. It will be seen, therefore, that the task assigned to Captain Perry required quick decision, courage and discretion. He possessed all those qualities in a high degree, and, in the performance of his duty, reached the mouth of the Orinoco in July, 1815, in command of three powerful ships. The following extract from his journal will give a vivid idea of the discomforts which he and his men underwent in the performance of their work:
