Empty treasure chests dumped from departed ships
And jettisoned slaves washed
Into an arc from Jamaica to Guiana.
Islands aborted from the belly of the sea
Forever unborn in rock and swamp.
Other fragments rot in the sun
Like cane chewed and spat
From coolie mouth.
Haiti is a crab with broken claw.
Cuba droops in fear at the foot of America.
This line is a  form of symbolism as it depicts something that is only used for flavor, when a person is done succumbing all the juices and good flavor, it is spited out and tossed for garbage. Dabydeen depicts this picture in the readers mind to show the symbolism of these islands being used.After taking their “sweet juices” their resources, they are no longer cared for or given importance. Below is a picture of fresh canes, which can symbolize how the islands appear before they are chewed up. 
 
  the next photo is the beginning of what happens when a sugar cane is cut. It is evident that it begins to loose its form and it’s sweetness furthermore, its taste is stripped down.
