 In this excerpt from the poem "Thanatopsis" by William Cullen Bryant, the writer tells us that when we die, we will "sleep" with all kinds of elegant and important people. There will be "patriarchs" (meaning parents, heads of families or male leaders) long since when the Earth was young ("the infant world"). This section of the poem deals precisely with the idea that when we die we all lie down together in a large grave, the writer making it sound like something good.
  The answer to the meaning of the word infant has to do with the letter B) past.
