Now he tilted his head a little and looked down at the bluff beneath him. The game was beginning. He must get down that bluff and overtake those specks and drive them somewhere. He glanced up and down the bluff to see if a better trail offered. Billy Louise laughed understandingly.

"It's this or nothing, Blue. Looks pretty fierce, all right, doesn't it? Of course, if you're going to make a perfect lady get off and walk—"

Blue snuffed at the ledge with his neck craned. The rim-rock had crumbled and sunk low into the bluff, like a too rich pie-crust when the oven is not quite hot enough. From a ten- or fifteen-foot wall it shrunk here to a three-foot ledge. And below the rocks and bowlders were not actually piled on top of one another; there were clear spaces where a wary, wise, old cow-horse might possibly pick his way.

Blue chose his trail and crumpled at the knees with his hoofs on the very edge of the ledge; went down with a cat-jump and landed with all four feet planted close together. He had no mind to go on sliding in spite of himself, and the bluff was certainly steep enough to excuse a bungle.

"So far so good." Billy Louise glanced ruefully back at the ledge. "We're down; but how the deuce do you reckon we'll get up again?"

Blue was not worrying about that part. He went on, picking his way carefully among the bowlders, with his nose close to earth, setting his hindlegs stiffly and tobogganing down loose, shale slopes. Billy Louise sat easily in the saddle and enjoyed it all. She was making up in big doses for the drab dullness of those hospital weeks. She ought to walk down the bluff, for this was dangerous play; but she craved danger as an antidote to that shut-in life of petty rules and regulations.

It was with a distinct air of triumph that Blue reached the bottom, even though he slid the last forty feet on his haunches and landed belly-deep in a soft snow-bank. It was with triumph to match his perky ears that Billy Louise leaned and slapped him on the neck. "We made it!" she cried, "and I didn't have to walk a step, did I, Blue? You're there with the goods, all right!"

Blue scrambled out of the bank to firm footing on the ripened grass of the bottom, and with a toss of his head set off in a swinging lope, swerving now and then to avoid a badger hole or a half-sunken rock. They had done something new, those two; they had reached a place where neither had ever been before, and Blue acted as if he knew it and gloried in the escapade quite as much as did his lady.

The cattle spied them and went trotting away up the river, and Blue quickened his stride a little and followed after. Billy Louise left the reins loose upon his neck. Blue could handle cattle alone quite as skillfully as with a rider, if he chose.

The cattle dodged into a fringe of bushes close to the river and disappeared, which was queer, since the bluff curved in close to the bank at that point. Blue pricked up his ears and went clattering after, slowed a little at the willow-fringe, stuck his nose straight out before him, and went in confidently. The cattle were just ahead. He could smell them, and his listening ears caught their heavy breathing. It was very rocky there in the willows, and he must pick his way with much care. But when he crashed through on the far side, and Billy Louise straightened from leaning low along his neck to avoid the stinging branches, the cattle gave a snort and went lumbering away, still following the river.
