The Rumble

Now I hear it,

Now I don’t,

A certain rumble distant.

It neither ceases,

Nor it grows,

It proceeds, it goes.

Like the looming thunder,

Over grey clouds,

Anon the raindrops,

Like the lightning,

Bright and blinding,

I see it, then I don’t.

I wonder what it is,

Nay, where is it,

Out, or within.
