From a single cloud the lightening flashes,
Whilst a thousand isles are illumined around,
Earthquake is trampling one city to ashes,
An hundred are shuddering and tottering; the sound
Is bellowing underground.
3.
But keener thy gaze than the lightening's glare,
And swifter thy step than the earthquake's tramp;
Thou deafenest the rage of the ocean; thy stare
Makes blind the volcanoes; the sun's bright lamp
To thine is a fen-fire damp.
4.
From billow and mountain and exhalation
The sunlight is darted through vapour and blast;
From spirit to spirit, from nation to nation,
From city to hamlet thy dawning is cast,—
The world ‘billow’, the first in this triplet, could be a verb or a noun, and may refer to ‘billowing’ clouds, while ‘exhalation’ probably refers to wind. There are two conjunctions, so this is a  syndetic  list, The repetition of ‘and’ gives emphasis.
