THE DESCENT OF THE RIO GY-PARANA 253 



faintly outlined against the dim background of merging 

 shadows and sombre green; somehow they seemed to fit 

 into the picture and to complete the impression of primality 

 conveyed by the vast wilderness of the Brazilian hinter- 

 land. Our captain held up bunches of bright-red beads 

 and started to wade into the stream toward them ; but they 

 immediately withdrew into the thick cover, so he came 

 back. A moment later they reappeared and again began 

 talking and waving their arms; by signs we tried to induce

 that we shall never forget. Assuming a rigid pose, he 

 pointed straight in front of him with one hand, as if tak- 

 ing aim; then with a sudden "pong" he clutched at his 

 breast and fell upon his knees, gradually sinking to the 

 ground, where he lay moaning. We understood the ac-
