CHAPTER XXI.
-- and wither'd Murder, Alarum'd by his sentinel, the wolf, Whose howl's his watch, thus with his stealthy pace, With Tarquin's ravishing strides, towards his design Moves like a ghost.
MACBETH.
For the space of a quarter of an hour, or longer, after the incident related, all remained perfectly quiet in the front of the royal habitation.

The King read and mused in the entrance of his pavilion; behind, and with his back turned to the same entrance, the Nubian slave still burnished the ample pavesse; in front of all, at a hundred paces distant, the yeomen of the guard stood, sat, or lay extended on the grass, attentive to their own sports, but pursuing them in silence, while on the esplanade betwixt them and the front of the tent lay, scarcely to be distinguished from a bundle of rags, the senseless form of the marabout.
But the Nubian had the advantage of a mirror from the brilliant reflection which the surface of the highly-polished shield now afforded, by means of which he beheld, to his alarm and surprise, that the marabout raised his head gently from the ground, so as to survey all around him, moving with a well-adjusted precaution which seemed entirely inconsistent with a state of ebriety.

He couched his head instantly, as if satisfied he was unobserved, and began, with the slightest possible appearance of voluntary effort, to drag himself, as if by chance, ever nearer and nearer to the King, but stopping and remaining fixed at intervals, like the spider, which, moving towards her object, collapses into apparent lifelessness when she thinks she is the subject of observation.

This species of movement appeared suspicious to the Ethiopian, who, on his part, prepared himself, as quietly as possible, to interfere, the instant that interference should seem to be necessary.
The marabout, meanwhile, glided on gradually and imperceptibly, serpent-like, or rather snail-like, till he was about ten yards distant from Richard's person, when, starting on his feet, he sprung forward with the bound of a tiger, stood at the King's back in less than an instant, and brandished aloft the cangiar, or poniard, which he had hidden in his sleeve.

Not the presence of his whole army could have saved their heroic Monarch; but the motions of the Nubian had been as well calculated as those of the enthusiast, and ere the latter could strike, the former caught his uplifted arm.
