The flower-scented breeze and the rumbling of the river persisted long after the valley lay behind and above, but these failed at length in the close air of the huge abutting walls. The light grew thick, the stones cracked like deep bell-strokes; the voices of man and girl had a hollow sound and echo. Silvermane clattered down the easy trail at a gait which urged Hare now and then from walk to run. Soon the gully opened out upon a plateau through the centre of which, in a black gulf, wound the red Colorado, sullen-voiced, booming, never silent nor restful. Here were distances by which Hare could begin to comprehend the immensity of the canyon, and he felt lost among the great terraces leading up to mesas that dwarfed the Echo Cliffs. All was bare rock of many hues burning under the sun.
"Jack, this is mescal," said the girl, pointing to some towering plants.
All over the sunny slopes cacti lifted slender shafts, unfolding in spiral leaves as they shot upward and bursting at the top into plumes of yellow flowers. The blossoming stalks waved in the wind, and black bees circled round them.
"Mescal, I've always wanted to see the Flower of the Desert from which you're named. It's beautiful."Hare broke a dead stalk of the cactus and was put to instant flight by a stream of bees pouring with angry buzz from the hollow centre. Two big fellows were so persistent that he had to beat them off with his hat.
"You shouldn't despoil their homes," said Mescal, with a peal of laughter.
"I'll break another stalk and get stung, if you'll laugh again," replied Hare.
They traversed the remaining slope of the plateau, and entering the head of a ravine, descended a steep cleft of flinty rock, rock so hard that Silvermane's iron hoofs not so much as scratched it. Then reaching a level, they passed out to rounded sand and the river.
"It's a little high," said Hare dubiously. "Mescal, I don't like the looks of those rapids."Only a few hundred rods of the river could be seen. In front of Hare the current was swift but not broken. Above, where the canyon turned, the river sheered out with a majestic roll and falling in a wide smooth curve suddenly narrowed into a leaping crest of reddish waves. Below Hare was a smaller rapid where the broken water turned toward the nearer side of the river, but with an accompaniment of twisting swirls and vicious waves.
"I guess we'd better risk it," said Hare, grimly recalling the hot rock, the sand, and lava of the desert.
"It's safe, if Silvermane is a good swimmer," replied Mescal. "We can take the river above and cut across so the current will help.""Silvermane loves the water. He'll make this crossing easily. But he can't carry us both, and it's impossible to make two trips. I'll have to swim."Without wasting more words and time over a task which would only grow more formidable with every look and thought, Hare led Silvermane up the sand-bar to its limit. He removed his coat and strapped it behind the saddle; his belt and revolver and boots he hung over the pommel.
"How about Wolf? I'd forgotten him."
"Never fear for him! He'll stick close to me.""Now, Mescal, there's the point we want to make, that bar; see it?""Surely we can land above that."
"I'll be satisfied if we get even there. You guide him for it. And, Mescal, here's my gun. Try to keep it from getting wet. Balance it on the pommel--so. Come, Silver; come, Wolf.""Keep up-stream," called Mescal as Hare plunged in. "Don't drift below us."In two steps Silvermane went in to his saddle, and he rolled with a splash and a snort, sinking Mescal to her hips. His nose level with the water, mane and tail floating, he swam powerfully with the current.
For Hare the water was just cold enough to be delightful after the long hot descent, but its quality was strange. Keeping up-stream of the horse and even with Mescal, he swam with long regular strokes for perhaps one-quarter of the distance. But when they reached the swirling eddies he found that he was tiring. The water was thick and heavy; it compressed his lungs and dragged at his feet. He whirled round and round in the eddies and saw Silvermane doing the same. Only by main force could he breast his way out of these whirlpools. When a wave slapped his face he tasted sand, and then he knew what the strange feeling meant.
There was sand here as on the desert. Even in the depths of the canyon he could not escape it. As the current grew rougher he began to feel that he could scarcely spread his arms in the wide stroke. Changing the stroke he discovered that he could not keep up with Silvermane, and he changed back again. Gradually his feet sank lower and lower, the water pressed tighter round him, his arms seemed to grow useless. Then he remembered a saying of August Naab that the Navajos did not attempt to swim the river when it was in flood and full of sand. He ceased to struggle, and drifting with the current, soon was close to Silvermane, and grasped a saddle strap.
"Not there!" called Mescal." He might strike you. Hang to his tail!"Hare dropped behind, and catching Silvermane's tail held on firmly. The stallion towed him easily. The waves dashed over him and lapped at Mescal's waist. The current grew stronger, sweeping Silvermane down out of line with The black wall which had frowned closer and closer. Mescal lifted the rifle, and resting the stock on the saddle, held it upright. The roar of the rapids seemed to lose its volume, and presently it died in the splashing and slapping of broken water closer at hand. Mescal turned to him with bright eyes; curving her hand about her lips she shouted:
"Can't make the bar! We've got to go through this side of the rapids.
Hang on!"
