Roderick Hardinge remained on guard from ten till twelve. As we have seen, he was sharply observant of everything that lay before him. But there was one point of the horizon to which his eye more assiduously turned. It was the high road leading from Levis over the table-land of the Beauce back to the forests. It was evidently from this direction that the object of his watch was to appear. And he was not disappointed. Just as the first stroke of twelve sounded from the turret of Notre-Dame Cathedral, a blue light shot into the air from a point on this road, not more than a hundred yards from the river bank. Roused by the sight, Roderick straightened himself up, snatched his carbine from his left side, threw it up on his right shoulder and presented arms. The sixth stroke of midnight was just heard, when a second blue light darted skyward, but this time fully fifty yards nearer. The man who fired it was evidently running toward the river. Roderick made a step forward and uttered a low cry. The last stroke of the twelve had hardly been heard, when a third light whizzed up from the very brink of the river. Roderick turned briskly round and gave a shrill whistle. The faithful soldier, whose watch he had assumed, immediately rushed forward, had his musket thrust back into his hands, with an injunction from Hardinge to keep silence. The latter had barely time to recede into the darkness when the relief-guard, consisting of a corporal and two privates, came to the spot and the usual formality of changing sentries was gone through. II. BEYOND THE RIVER. With a throbbing heart, Roderick Hardinge walked rapidly over the brow of the citadel into Upper Town. He glanced up at the Chateau as he passed, but the lights which were visible there two hours before, were now extinguished, and the Governor was sleeping without a dream of the mischief that was riding out upon the city that night. He passed through the Square and overhead the wassail of the officers over their wine and cards. He answered the challenge of the sentinel at the gate which guarded the heights of Mountain Hill, and doubled his pace down that winding declivity. The old hill has been the scene of many an historic incident, but surely of none more momentous than this midnight walk of Roderick Hardinge. Along the dark, narrow streets of Lower Town, stumbling over stones and sinking into cavities. Not a soul on the way. Not a sign of life in the square, black warehouses, with their barricades of sheet-iron doors and windows.
