But would’st thou see thy negroe-train encrease, Free from disorders; and thine acres clad With groves of sugar
These two are inherently tied. The slave population as like the sugar cane: different varieties, prone to pests, requiring specific "care," etc. The slaves and the commodity produced by their labor become one. (Reminds me of how the Chinese workers on the transcontinental railroad were equated to the train itself to deny them housing and sustenance. As the laborer is alienated from both their labor and their humanity, they themselves become the commodity produced.)
