How, indeed, was the question. Mr. Macrae had many things to engross his attention, and Mrs. Macrae was so used to Hector's roaming about on his own account, that she would not be apt to miss him until sundown. As it fell out, it was from a most unlooked-for source that the clue came. Having made the best arrangements they could for shelter, and these were very scant at best, the settlers gathered together for their evening meal. Then did the mother-heart of Mrs. Macrae begin to feel concerned for her son. 'Where is Hector?' she asked her husband. 'I have na seen him these many hours. Was he no with you?'

'He was no with me at all,' answered Mr. Macrae, turning his keen glance in every direction. 'He went aff with the twa dogs a gude while ago, and I didna see just which way he went.'

'God grant he's na got into any harm!' sighed Mrs. Macrae. ''Tis a strange place this, and there's na tellin' what may happen to the laddie.'

'Oh, he's a' richt,' responded her husband, cheerfully. 'He'll be wanting his bannocks, and that'll bring him back soon.'

But when night fell, and still no sign of Hector, the Macraes grew very anxious. Andrew set out to make enquiries, and went through the party of settlers, asking if any of them had seen the boy since mid-day. Several of them had noticed him strolling about, accompanied by the dogs, but no one could say definitely in what direction he had gone.

When the mystery was at its height, and the whole party was aroused to concern for the missing boy, suddenly Dour appeared, and rushed up to Mr. Macrae, barking joyfully. The remains of a raw-hide thong, which he had bitten through close to his body, hung about his neck, and, with all the means of expression at the command of the most sagacious of his kind, he strove to tell his story.

'Gude dog! Gude dog!' murmured Mr. Macrae, patting the clever creature fondly. 'There's been ill wark, nae doot. Come with me, friends, an' we'll sift it to the verra bottom.'

Slipping pistols into their pockets, for there was no telling what might happen, half-a-dozen of the men signified their readiness to accompany Mr. Macrae in the search for his son. They were stalwart, stern-looking men, with shaggy faces, and piercing, fearless eyes—not the men to be trifled with by any one, and now deeply intent upon their purpose, for their hearts beat in sympathy for the anxious father and mother.

'Lead on, Dour, gude dog,' said Andrew; 'ye dootless ken the way. We'll keep close ahind ye.'

The intelligent animal, fully grasping his master's meaning, set off at once straight for the fort, the men following at a rapid jog-trot, in order not to be left behind. When they arrived at the fort they found the gate closed, but, as Dour was insistent about entering, Mr. Macrae did not hesitate to rap loud and long upon the stout timber with the butt of his pistol.
