From Twenty Years Before the Mast, by Charles Erskine (Fossil, 2016), Kindle p. 186:
I found stowing cotton in a ship’s hold to be the most exhausting labor I had ever performed. We wore nothing but trousers, with a bandana handkerchief tied over our heads. The hold was a damp, dark place. The thermometer stood at nearly one hundred, not a breath of air stirred, and our bodies were reeking with perspiration. This was more than my frail body could endure. When I was paid, Saturday evening, with eight silver Spanish dollars for my four days’ labor, I came to the conclusion that they were the hardest eight dollars I had ever earned, and that there would be no more screwing cotton by the day for me.
The following Monday I went to work at painting ships and steamboats for an old Portuguese, by the name of Desimees, in Algiers, a town situated on the opposite side of the river. A party of five, one an old shipmate of mine, hired a small shanty and kept bachelor’s hall. We employed an old colored woman as housekeeper. On Saturdays we used to quit work early and go across the river to New Orleans and purchase our weekly supply of provisions. Although there was a United States mint in the city, there were at this time no cents in circulation. The smallest pieces of money were a five-cent piece, and a picayune, — six and a quarter cents, — and a Spanish coin called fourpence. It used to confuse Jack before the mast very much, that in Boston it was six shillings to the dollar, and in New York eight; that an eighth of a dollar, or twelve and a half cents, should be called ninepence in Boston, a shilling in New York, a long bit in New Orleans, and a levy in the Western States.
