"Now on the hills I hear the thunder mutter... Nearer and nearer rolls the thunder-clap, - You can hear the quick heart of the tempest beat.... Look! look! that livid flash! And instantly follows the rattling thunder, As if some cloud-crag, split asunder, Fell, splintering with a ruinous crash, On the Earth, which crouches in silence under; And now a solid gray wall of rain Shuts off the landscape, mile by mile."
