Part 26 (1/2)

”Then sit tight, and we'll rush her up on the top gear.”

The dust whirled behind them, and the cropped hedgerows spun past; they swung giddily round a curve at a bridge, and the throb of the engine grew louder as they breasted the hill. Dark firs streamed down to meet them; here and there a leafless birch and an oak that gleamed like burnished copper swept by. There was a tinkle of running water in the wood; and, now that they were out of the suns.h.i.+ne, the air felt keen. Ahead, the ascending road unrolled like a white riband through faint, s.h.i.+fting lights and lilac shadow.

Soon the glen ran out into a wide hollow that led westward across a tableland. Low, green hills with gently rounded tops shut off the rugged moors beyond; the shallow vale was cultivated and tame, but the road was good, and Andrew felt the thrill of speed. Long fields and stone d.y.k.es swept behind into the trail of dust. The sun sank toward a bank of slate-colored cloud; its rays raked the valley, throwing the black shadows of the scattered ash-trees far across the fields.

Andrew kept his eyes fixed steadily upon the road. This ran, for the most part, straight and level; but, though they were traveling very fast, there was no speeding streak of dust ahead.

After a time a long white village rose from the rolling pasture; and when they ran in among the low houses Whitney pulled up. There was a smith's shop by the roadside, and a man stood outside, holding a cartwheel, while another moved a glowing iron hoop amid the flame of a circular fire.

”You have been watching that tire heat for a while, I guess,” said Whitney.

”Lang enough,” the other answered. ”She's no' stretching weel.”

”Then have you seen a small, black motorcycle pa.s.s?”

”No; there was a big gray yin, an' anither with a side-car.”

”How long have you been outside?”

”Maybe twenty minutes; maybe a few mair.”

”Thanks,” said Whitney; and started the motorcycle.

”It's curious. He's traveling light, but I don't think a single-cylinder engine could beat the machine I'm driving by a quarter of an hour. Anyhow, I'll try to speed her up.”

The sunlight faded off the gra.s.s as they raced away; the slaty clouds rolled higher up the sky; and the wind that whipped their faces bit keen. Andrew was swung to and fro in the rocking car, and sometimes felt uneasy when his comrade dashed furiously round the bends; but for most of the way the road ran straight, and they could see nothing on the long, white streak ahead. After a time they came to a narrow loch, ruffled by the wind, that lay in a lonely, gra.s.sy waste, and as they ran past the thin wood on its edge Andrew asked Whitney to stop.

”A motor scout,” he said, indicating a man in uniform who rode leisurely toward them on a bicycle.

The scout dismounted when they called to him, and said he had left Castle Douglas an hour before and had kept to the main road, but had not seen a single-cylinder motorcycle. They let him go and Whitney lighted a cigarette.

”Now,” he said, ”we have to think. Our man pulled out for Castle Douglas, but hasn't gone there; my notion is that he didn't mean to.

Where's he likely to have headed?”

”It's hard to tell. A road runs northwest to New Galloway, but I can't see what would take him there. It's a small place on the edge of the moors.”

”And right away from the Eskdale road!” Whitney e.j.a.c.u.l.a.t.ed, looking hard at him.

”Well,” said Andrew quietly, ”I'll admit I thought of that.”

”As a matter of fact, you've been thinking of something like it for quite a time.”

Andrew was silent for a moment or two.

”There was a chance of my being mistaken,” he said slowly. ”However, I now feel that it's my duty to get upon the fellow's track, if I can.”

”Would you rather I dropped out?”

Andrew knew that the suggestion was prompted by delicacy, but he made a negative sign.
