By mount and fort they thread to swamp the sluggard plains.
Shines his gold-laurel sun, or cloak connivent rains.
They press to where the hosts in line and square throng mute;
He watchful of their form, the Audacious, the Astute;
Eagle to grip the field; to work his craftiest, fox.
From his brief signal, straight the stroke of the leveller falls;
From him those opal puffs, those arcs with the clouded balls:
He waves and the voluble scene is a quagmire shifting blocks;
