Key passages

  • The mightiest river in the world is the Amazon. It runs from west to east, from the sunset to the sunrise, from the Andes to the Atlantic.

    The Amazon is the world's greatest river, flowing westward to eastward from the Andes to the Atlantic.

    Sets the geographic context for the unknown river they are descending.

  • This river flowed northward toward the equator, but whither it would go, whether it would turn one way or another, the length of its course, where it would come out, the character of the stream itself, and the character of the dwellers along its banks⁠—all these things were yet to be discovered.

    The river's course, length, outlet, and the nature of its people were all unknown.

    Emphasizes the uncertainty and exploratory nature of the journey.

  • The head, feet, tail, skin, and entrails were boiled for the gaunt and ravenous dogs. The flesh gave each of us a few mouthfuls; and how good those mouthfuls tasted!

    Even the scraps were fed to the hungry dogs, and the small amount of meat was savored by the men.

    Illustrates the scarcity of food and the value of fresh meat.

  • It was a view well worth seeing; but, beautiful although the country ahead of us was, its character was such as to promise further hardships, difficulty, and exhausting labor, and especially further delay; and delay was a serious matter to men whose food supply was beginning to run short...

    The scenic view ahead foreshadowed more difficult work and delays, which threatened the dwindling food supply.

    Highlights the tension between beauty and the practical dangers of the expedition.
