Plato Profile Directory 03The river was smooth for a little distance, when we proceeded once more with our navigation; but soon it became narrow--only 40 to 50 m. wide--with strong eddies in its deep channel between rocky sides. Some magnificent sand beaches 15 to 20 ft. high were observed, particularly on the right bank, not far from a tributary 3 m. wide which entered the main river on the left side. Lower down, the river described a sharp turn, and there we met another most dangerous rapid. It was entered by a passage 50 m. wide, after which a circular basin of rock--evidently an ancient crater--100 m. in diameter appeared; then the water flowed out with terrific force by a channel only 30 m. wide. The stream produced prodigious eddies in the circular basin. Waves of great height were dashed to and fro from one side to the other of the narrow channel, between high rocks on either side. The water flowed first in a direction E.S.E. for 500 m., then turned off suddenly to due east for a distance of 400 m. That spot was most difficult for us to go through. I dare say you notice that all the birds in this picture have long beaks. We may be sure from this that they live in places and seek for their food in ways in which long beaks are just what they want. The fact is they are all marsh birds, and the soil of marshes being wet and soft, and full of worms, these long beaks enable them to probe it, and so get at the worms. I think the beaks of birds afford a striking example of how good God is in adapting creatures to the mode of life He has appointed for them. The eagles and hawks, you know, are provided with strong, short bills to enable them to seize and tear flesh. Those of canaries and all the finches are just the very instruments to crack seeds with. Parrots, with their tremendous weapons, can crush the hardest nuts of the tropic forest. The crossbill is fitted with a wonderful tool for tearing fir-cones to pieces. Robins and the other warblers have soft bills, which are all they want for eating insects and grubs. | |
