My tongue, every atom of my blood, form'd from this soil, this air, Born here of parents born here from parents the same, and their parents the same, I, now thirty-seven years old in perfect health begin, Hoping to cease not till death. Creeds and schools in abeyance, Retiring back a while sufficed at what they are, but never forgotten, I harbor for good or bad, I permit to speak at every hazard, Nature without check with original energy. I am satisfied--I see, dance, laugh, sing; As the hugging and loving bed-fellow sleeps at my side through the night, and withdraws at the peep of the day with stealthy tread, Leaving me baskets cover'd with white towels swelling the house with their plenty, Shall I postpone my acceptation and realization and scream at my eyes, That they turn from gazing after and down the road, And forthwith cipher and show me to a cent, Exactly the value of one and exactly the value of two, and which is ahead? Backward I see in my own days where I sweated through fog with linguists and contenders, I have no mockings or arguments, I witness and wait.
