THE GAPO. 313 



the rustling of leaves overhead tells us that monkeys are near, 

 and we soon see them peeping down from among the thick 

 foliage, and then bounding rapidly away. Presently we come 

 out into the sunshine, on a lake filled with lilies and beauti- 

 ful water-plants, little bladder-worts, and the bright blue 

 flowers and curious leaves with swollen stalks of the ponte- 

 derias. Again we are in the gloom of the forest, among the 

 lofty cylindrical trunks rising like columns out of the deep 

 water ; and now there is a splash of fruit falling around us, 

 announcing that birds are feeding overhead, and we discover

 tribes, who, spending most of their time in their canoes, in 

 the dry season build small huts on its .sandy shores ; and 

 when the waters overflow it, form rafts, which they secure 

 between the trees, sleeping in rude huts suspended from the 

 stems over the deep water, and lighting their fires on masses

Several species of trogons are peculiar to this submerged 

 region. The curious black umbrella-bird is -entirely confined 

 to it, as is also the little bristle-tailed manakin. Several 

 monkeys visit it during the wet season, for the sake of its 

 peculiar fruits ; and here the scarlet-faced urikari has its home. 



For miles and miles together the native traverses this
