This is done two days after the coating. In a week, the shoes are taken from the last. The coating occupies about twenty-five minutes. The tree is tall, straight, and has a smooth bark. It sometimes reaches a diameter of thirteen inches or more. Each incision makes a rough wound on the tree, which, although it does not kill it, renders it useless, because a smooth place is wanted to which to attach the cups. The milk is white and tasteless, and may be taken into the stomach with impunity. Our travellers arrived at Pará on the 12th of April, 1852, and were most hospitably and kindly received by Mr. Norris, the American consul. The journey of our travellers ends here. Lieut. Herndon's book is full of instruction, conveyed in a pleasant style. He seems to have manifested throughout good judgment, good temper, energy, and industry. He had no collisions with the authorities or with individuals, and, on his part, seems to have met friendly feelings and good offices throughout his whole route. William Lewis Herndon was born in Fredericksburg, Va., on the 25th of October, 1813. He entered the navy at the age of fifteen; served in the Mexican war; and was afterwards engaged for three years, with his brother-in-law, Lieut. Maury, in the National Observatory at Washington. In 1851-2, he explored the Amazon River, under commission of the United-States Government. In 1857, he was commander of the steamer "Central America," which left Havana for New York on Sept. 8, having on board four hundred and seventy-four passengers and a crew of one hundred and five men, and about two million dollars of gold. On Sept. 11, during a violent gale from the north-east and a heavy sea, she sprung a leak, and sunk, on the evening of Sept. 12, near the outer edge of the Gulf Stream, in lat. 31° 44´ N. Only one hundred and fifty of the persons on board were saved, including the women and children. The gallant commander of the steamer was seen standing upon the wheel-house at the time of her sinking. In a former chapter, we have told the fate of Sir Humphrey Gilbert. How fair a counterpart of that heroic death is this of the gallant Herndon! CHAPTER XV. LATEST EXPLORATIONS.
