It begins to rise in April and to fall in August. The confluence with the Amazon is strikingly marked by a line of drifting leaves, sods of water plants, and uprooted trees, but most strikingly by the contrast in color of the two streams. The Negro water is very dark, almost pure black, but in bucketfuls it appears to be coffee-colored, while that of the Amazon is tawny-colored, both in the mass and in small quantities.

Rubber makes nearly all the business of the Amazon and its great tributaries. In spits of fevers and debilitating heat, etc., thousands of men, young and old, rush half crazy, half merry, into the rubbery wilderness for fortunes.
