"It is only that child we found at the stockade," he murmured, and stepped on among the older mounds and leaped the opposite boundary, to descend that dip of land which the tide invaded. Water yet shone there on the grass. Too impatient to wait until the tide ran low, he found the log, and moved carefully forward, through increasing dusk, on hands and knees within closer range of the fort. Remembering that his buckskin might make an inviting spot on the slope, he wrapped his dark blanket around him. The chorus of insect life and of water creatures, which had scarcely been tuned for the season, began to raise experimental notes. And now a splash like the leap of a fish came from the river. The moon would be late; he thought of that with satisfaction. There was a little mist blown aloft over the stars, yet the night did not promise to be cloudy.

The whole environment of Fort St. John was so familiar to the young soldier that he found no unusual stone in his way. That side toward the garden might be the side least exposed to D'Aulnay's forces at night. If he could reach the southwest bastion unseen, he could ask for a ladder. There was every likelihood of his being shot before the sentinels recognized him, yet he might be more fortunate. Balancing these chances, he moved toward that angle of shadow which the fortress lifted against the southern sky. Long rays of light within the walls were thrown up and moved on darkness like the pulsing motions of the aurora.

"Who goes there?" said a voice.

The soldier lay flat against the earth. He had imagined the browsing sound of cattle near him. But a standing figure now condensed itself from the general dusk, some distance up the slope betwixt him and the bastion. The challenger was entirely apart from the fort. As he flattened himself in breathless waiting for a shot which might follow, a clatter began at his very ears, some animal bounded over him with a glancing cut of its hoof, and galloped toward the trench below St. John's gate. He heard another exclamation,—this rapid traveler had probably startled another sentinel. The man who had challenged him laughed softly in the darkness. All the Sable Island ponies must be loose upon the slope. D'Aulnay's men had taken possession of the stable and cattle, and the wild and frightened ponies were scattered. As his ear lay so near the ground the soldier heard other little hoofs startled to action, and a snort or two from suspicious nostrils. He crept away from the sentinel without further challenge. It was evident that D'Aulnay had encompassed the fort with guards.

The young soldier crept slowly down the rocky hillock, avoided another sentinel, and, after long caution and self-restraint and polishing the earth with his buckskin, crawled into the empty trench. The Sable Island ponies continually helped him. They were so nervous and so agile that the sentinels ceased to watch moving shadows.

The soldier looked up at St. John and its tower, knowing that he must enter in some manner before the moon rose. He dreaded the red brightness of moon-dawn, when guards whom he could discern against the stony ascent might detect his forehead above the breastwork. Behind him stretched an alluvial flat to the river's sands. The tide was running swiftly out, and under starlight its swirls and long muscular sweeps could be followed by a practiced eye.

As the soldier glanced warily in every direction, two lights left D'Aulnay's camp and approached him, jerking and flaring in the hands of men who were evidently walking over irregular ground. They might be coming directly to take possession of the trench. But why should they proclaim their intention with torches to the batteries of Fort St. John? He looked around for some refuge from the advancing circle of smoky shine, and moved backwards along the bottom of the trench. The light stretched over and bridged him, leaving him in a stream of deep shadow, protected by the breastwork from sentinels above. He could therefore lift a cautious eye at the back of the trench, and scan the group now moving betwixt him and the river. There were seven persons, only one of whom strode the stones with reckless feet. This man's hands were tied behind his back, and a rope was noosed around his neck and held at the other end by a soldier.

"It is Klussman, our Swiss!" flashed through the soldier in the trench, with a mighty throb of rage and shame, and anxiety for the lady in the fort. If Klussman had been taken prisoner, the guns of St. John would surely speak in his behalf when he was about to be hanged before its very gate. Such a parade of the act must be discovered on the walls. It was plain that Klussman had deserted to D'Aulnay, and was now enjoying D'Aulnay's gratitude.

"The tree that doth best front the gates," said one of the men, pointing with his torch to an elm in the alluvial soil: "my lord said the tree that doth best front the gates."

"That hath no fit limbs," objected another.
