The happy husband now conveyed his wife to Oyapoc, and thence to Cayenne; whence they departed on their return to France, in company with the venerable Mr. De Grandmaison. Madame Godin remained, however, constantly sad, notwithstanding her present ample cause for joy; and every endeavor to raise her spirits was fruitless, so deep and inextinguishable an impression had the terrible sufferings she had undergone made upon her mind. She spoke unwillingly of all that she had suffered; and even her husband found out with difficulty, and by little and little, the circumstances which we have narrated, taken from accounts under his own hand. He thought he could thereby infer that she had kept to herself, to spare his feelings, many circumstances of a distressing nature, which she herself preferred to forget. Her heart, too, was, by reason of her sufferings, so attuned to pity and forbearance, that her compassion even extended to the base and wicked men who had treated her with such injustice. She would therefore add nothing to induce her husband to invoke the vengeance of the law against the faithless Tristan, the first cause of all her misfortunes, who had converted to his own use many thousand dollars' worth of property which had been intrusted to him. She had even allowed herself to be persuaded to take on board the boat from Omaguas down, for a second time, the mean-souled Mr. R. So true is it that adversity and suffering do fulfil the useful purpose of rendering the human heart tender, placable, and indulgent. CHAPTER XI. HERNDON'S EXPEDITION. In the month of August, 1850, Lieut. Herndon, of the United-States navy, being on board the frigate "Vandalia," then lying at anchor in the harbor of Valparaiso, received information that he was designated by the Secretary of the Navy to explore the Valley of the Amazon. On the 4th of April, being then at Lima, he received his orders, and, on the 21st of May, commenced his land journey to the highest point on the Amazon navigable for boats, which is about three hundred miles from its source; in which distance there are twenty-seven rapids, the last of which is called the Pongo (or falls) de Manseriche. Over these the water rushes with frightful rapidity; but they are passed, with great peril and difficulty, by means of rafts. From the Pongo de Manseriche, Lieut. Herndon states that an unbroken channel of eighteen feet in depth may be found to the Atlantic Ocean,--a distance of three thousand miles.
