"The trees are valueless without the Indians, who, besides getting rubber for them, do everything else these creatures need - feed them, build for them, run for them and carry for them and supply them with wives and concubines. They couldn't get this done by persuasion, so they slew and massacred and enslaved by terror, and that is the whole foundation. What we see today is merely the logical sequence of events - the cowed and entirely subdued Indians, greatly reduced in numbers, hopelessly obedient, with no refuge and no retreat, and no redress..."
