"What gets me is the feeling of what might be round the next bend," said Hal.
This indeed, Ken thought, made the fascination of such travel. The water was swift and smooth and shallow. There was scarcely a wave or ripple. At times the boat stuck fast on the flat rock, and the boys would have to get out to shove off. As far ahead as Ken could see extended this wide slant of water. On the left rose a thick line of huge cypresses all festooned with gray moss that drooped to the water; on the right rose a bare bluff of crumbling rock. It looked like blue clay baked and cracked by the sun. A few palms fringed the top.
"Say, we can beat this," said Ken, as for the twentieth time the boys had to step out and shove off a flat, shallow place. "Two of you in the bow and Pepe with me in the stern, feet overboard."
The little channels ran every way, making it necessary often to turn the boat. Ken's idea was to drift along and keep the boat from grounding by an occasional kick.
"Ken manages to think of something once in a while," observed Hal.
Then the boat drifted down-stream, whirling round and round. Here Pepe would drop his brown foot in and kick his end clear of a shallow ledge; there George would make a great splash when his turn came to ward off from a rock; and again Hal would give a greater kick than was necessary to the righting of the boat. Probably Hal was much influenced by the fact that when he kicked hard he destroyed the lazy equilibrium of his companions.
It dawned upon Ken that here was a new and unique way to travel down a river. It was different from anything he had ever tried before. The water was swift and seldom more than a foot deep, except in diagonal cracks that ribbed the river-bed. This long, shut-in stretch appeared to be endless. But for the quick, gliding movement of the boat, which made a little breeze, the heat would have been intolerable. When one of Hal's kicks made Ken lurch overboard to sit down ludicrously, the cool water sent thrills over him. Instead of retaliating on Hal, he was glad to be wet. And the others, soon discovering the reason for Ken's remarkable good-nature, went overboard and lay flat in the cool ripples. Then little clouds of steam began to rise from their soaked clothes.
Ken began to have an idea that he had been wise in boiling the water which they drank. They all suffered from a parching thirst. Pepe scooped up water in his hand; George did likewise, and then Hal.
"You've all got to stop that," ordered Ken, sharply. "No drinking this water unless it's boiled."
The boys obeyed, for the hour, but they soon forgot, or deliberately allayed their thirst despite Ken's command. Ken himself found his thirst unbearable. He squeezed the juice of a wild lime into a cup of water and drank that. Then he insisted on giving the boys doses of quinine and anti-malaria pills, which treatment he meant to continue daily.
