It was only a coyote, and afterwards she could never recall the episode without a blush, but the fact remains that while the grizzled apparition crowned a roll, she threw dignity overboard and clung to Carter. It was well, too, that she did, for more from deviltry than fear of the gray shadow the ponies just then bolted.

Ensued a minute of dust, wind, bumpings; then, without any attempt to check their speed, Carter got the mad little brutes back to the trail. Several furious miles had passed before, answering a gasping question as to whether he couldn't stop them, that imperturbable driver said:

"I ain't trying very hard. They're going our way, and we've got to hit this trail some licks to make Flynn's by noon. He's the first settler north of the valley."

They did hit it some "licks." One after another the yellow miles slid beneath the buck-board, deadly in their sameness. With the exception of that lone coyote, they saw no life. Right and left the tawny prairies reached out to the indefinite horizon; neither cabin nor farmstead broke their sweep; save where the dark growths of the Assiniboin Valley drew a dull line to the north, no spot of color marred that great monochrome. Just before they came to the valley Carter dashed around the Red River cart of a Cree squaw. Shortly after they came on her lord driving industrious heels into the ribs of a ragged pony. Then the trail shot through a bluff—rugged, riven, buttressed with tall headlands to whose scarred sides dark woods clung, the mile-wide valley lay before them. Up from its depths rose the cry of a bell. Clear, silvery, resonant, it flowed with the stream, echoed in dark ravines, filled the air with its rippling music.

"Catholic mission," Carter said, and as he spoke the ponies plunged after the trail which fell at an angle of forty-five into a black ravine. The girl felt as though the earth had dropped from under, then, bump! the wheels struck and went slithering and ricochetting among the ruts and bowlders. A furious burst down the last slopes and they were galloping out on the bottom-lands.

"Oh!" she exclaimed, regaining breath. "What recklessness!"

"Now do you really call that reckless?" His mild surprise would have been convincing but for the wicked twinkle.

"Of course—I do," she said, choking with fright and indignation. "I believe—you did it on purpose."

"Well, well." He shook a sorrowful head. "And to think I shouldn't have knowed it! Look out!"

They had swung by the log mission with the black-robed priest in the door, circled the ruins of a Hudson Bay fort, and now the Assiniboin Ford had suddenly opened before them. Fed fat by mountain streams, the river poured, a yeasty flood, over the ford, a roaring terror of swift waters. While the girl caught her breath they were in to the hubs, the thills; then the green waters licked up through the buck-board staves. Half wading, half swimming, the ponies were held to the narrow passage by that master-hand. On either side smooth, sucking mouths drew down to dangerous currents, and, reaching, Carter flicked one with his whip.
