"On the last day of this month. Until then you must not leave this camp; and after the army marches you must not go outside this fort. Amochol's arm is long. His acolytes are watching. And now I think you understand at last."
She nodded. Presently she rested her pale cheek on her arms and looked at the reddening edges of the woods. Northwest lay Catharines-town, so Mayaro said. And into the northwest her grey eyes now gazed, calmly and steadily, while the sun went out behind the forest and the high heavens were plumed with fire.
Under us the river ran, all pink and primrose, save where deep, glassy shadows bounded it under either bank. The tips of the trees glowed with rosy flame, faded to ashes, then, burnt out, stood once more dark and serrated against the evening sky.
Suddenly an unearthly cry rang out from somewhere close to the river bank up stream. Instantly a sentry on the parapet near us fired his piece.
"Oh, God! What is it!" faltered Lois, grasping my arm. But I sprang for the ladder and ran down it; and the scattered soldiers and officers below on the parade were already running some grasping their muskets, others drawing pistols and hangers.
We could hear musketry firing ahead, and drums beating to arms in our camp behind us.
"The cattle-guard!" panted an officer at my elbow as we ran up stream along the river-bank. "The Senecas have made their kill again, God curse them!"
It was so. Out of the woods came running our frightened cattle, with the guard plodding heavily on their flanks; and in the rear two of our soldiers urged them on with kicks and blow; two more retreated backward, facing the dusky forest with levelled muskets, and a third staggered beside them, half carrying, half trailing a man whose head hung down crimsoning the leaves as it dragged over them.
He had been smoking a cob pipe when the silent assassin's hatchet struck him, and the pipe now remained clenched between his set teeth. At first, for the dead leaves stuck to him, we could not see that he had been scalped, but when we turned him over the loose and horrible features, all wrinkled where the severed brow-muscles had released the skin, left us in no doubt.
"This man never uttered that abominable cry," I said, shuddering. "Is there yet another missing from the guard?"
