The Death of a Toad, Richard Wilbur
1. A toad the power mower caught,
2. Chewed and clipped of a leg, with a hobbling hop has got
3. To the garden verge, and sanctuaried him
4. Under the cineraria leaves, in the shade
5. Of the ashen and heartshaped leaves, in a dim,
6. Low, and a final glade.
7. The rare original heartsblood goes,
8. Spends in the earthen hide, in the folds and wizenings, flows
9. In the gutters of the banked and staring eyes. He lies
10. As still as if he would return to stone,
11. And soundlessly attending, dies
12. Toward some deep monotone,
13. Toward misted and ebullient seas
14. And cooling shores, toward lost Amphibia's emperies.
15. Day dwindles, drowning and at length is gone
16. In the wide and antique eyes, which still appear
17. To watch, across the castrate lawn,
18. The haggard daylight steer.
