Of a black cloud diffused o'er half the sky:[GH]

Or as a fruitful palm-tree towering high

O'er the parched waste beside an Arab's tent;

Or the Indian tree whose branches, downward bent,

Take root again, a boundless canopy.

How sweet were leisure! could it yield no more

Than 'mid that wave-washed Church-yard to recline,

From pastoral graves extracting thoughts divine;

Or there to pace, and mark the summits hoar

Of distant moon-lit mountains faintly shine,
