Assonans

The trees are undressing, and fling in many places --
On the gray road, the roof, the window-sill --
Their radiant robes and ribbons and yellow laces;
A leaf each second so is flung at will,
Here, there, another and another, still and still.
A spider’s web has caught one while downcoming,
That stays there dangling when the rest pass on;
Like a suspended criminal hangs he, mumming
In golden garb, while one yet green, high yon,
Trembles, as fearing such a fate for himself anon.

- jeg kan simpelthen ikke finde assonans i dette digt, er der nogen der kan hjælpe mig??
