316 TRIP UP AN IGARAPE. 



ally a porpoise emerges from the water, showing himself for a 

 moment, and then disappearing. Sometimes a herd of 

 capybaras, resting on the water's edge, are startled at our 

 approach. 



There sits, on the branch of an imbauba, rolled up in its 

 peculiar attitude, a sloth, the very picture of indolence, with 

 its head sunk between its arms. The banks, covered in many 

 places with the beautiful capim-grass, afford excellent pastur- 

 age for cattle. 



Now we turn into an inner stream, or igarape, often having 

 to make our way with difficulty amid islands of capim-grass. 

 Now we pass through a magnificent forest of the beautiful 

 fan-palm the miriti overshadowing many smaller trees 

 and innumerable shrubs, bearing light conspicuous flowers. 

 Among them are numerous Leguminosse one of the most

 The capim is bright with the blossoms of the mallow grow-

The sedgy grasses on either side are full of water birds. 

 One of the most -common is a small chestnut-brown wading

 them up usually in pairs. Their flat, open nests generally
