Key passages

  • Spilett took the box and opened it. It contained a white powder, which he tasted. Its extreme bitterness was unmistakable. It was indeed that precious alkaloid, the true anti-periodic.

    Spilett opened the box and tasted the white powder inside, recognizing its extreme bitterness as quinine, a valuable medicine for fevers.

    The mysterious arrival of quinine saves Herbert's life.

  • The colonists were familiar with all the eastern coast of the island between Claw Cape and the Mandibles; with Tadorn’s Fens; the neighborhood of Lake Grant; the portion of Jacamar Wood lying between the road to the corral and the Mercy; the courses of the Mercy and Red Creek, and those spurs of Mount Franklin where the corral was located.

    The colonists knew the eastern coast, Tadorn's Fens, Lake Grant, parts of Jacamar Wood, the rivers, and the area around the corral, but much of the island remained unexplored.

    The colonists review their knowledge of the island before the expedition.

  • The five convicts had evidently camped here; but⁠—and they made minute search⁠—they could not discover a sixth track, which would have been that of Ayrton.

    The colonists found evidence that five convicts had camped there, but a thorough search revealed no sixth set of footprints that would belong to Ayrton.

    The absence of Ayrton's tracks suggests he may have been killed.
