"Might be that. Men do in this country a lot. We don't know what a tough time he's been through."

"I'll bet he's bucked blizzards aplenty in the last two months. Notice one thing. West's trailin' after the guide like a lamb. He's makin' a sure-enough drunk track. See how the point of his shoe caught the snow there an' flung him down. The Cree stopped the sled right away so West could get up. Why did he do that? And why don't West ever stray a foot outa the path that's broke? That's not like him. He's always boss o' the outfit—always leadin'."

Beresford was puzzled, too. "I don't get the situation. It's been pretty nearly a thousand miles that we've been following this trail—eight hundred, anyhow. All the way Bully West has stamped his big foot on it as boss. Now he takes second place. The reason's beyond me."

His friend's mind jumped at a conclusion. "I reckon I know why he's followin' the straight and narrow path. The guide's got a line round his waist and West's tied to it."

"Why?"

The sun's rays, reflected from the snow in a blinding, brilliant glare, smote Morse full in the eyes. For days the white fields had been very trying to the sight. There had been moments when black spots had flickered before him, when red-hot sand had been flung against his eyeballs if he could judge by the burning sensation.

He knew now, in a flash, what was wrong with West.

To Beresford he told it in two words.

The constable slapped his thigh. "Of course. That's the answer."

Night fell, the fugitives still not in sight. The country was so rough that they might be within a mile or two and yet not be seen.
