Of the many second-hand booksellers (or rather sellers of second-hand books) in American cities, the more notable have passed from the stage of action in the last quarter of a century. Old William Gowans, a quaint, intelligent Scotchman, in shabby clothes and a strong face deeply marked with small pox, was for many years the dean of this fraternity in New York. His extensive book-shop in Nassau street, with its dark cellar, was crowded and packed with books on shelves, on stairways and on the floors, heaped and piled in enormous masses, amid which the visitor could hardly find room to move. On one of the piles you might find the proprietor seated-- Books to the right of him, Books to the left of him, Books behind him, Volleyed and tumbled, while he answered inquiries for books from clergymen and students, or gruffly bargained with a boy or an old woman for a dilapidated lot of old books. He had a curious quizzical way with strangers, who at once set him down as an oddity, and his impatience with ignoramuses and bores gave him the repute of crustiness, which was redeemed by suavity enough whenever he met with people of intelligence. Gowans issued scores of catalogues of his stock, in which titles were often illustrated by notes, always curious and often amusing, credited to "Western Memorabilia," a work which no bookseller or man of letters had ever heard of, but which was shrewdly suspected to have been a projected scrap-book of the observations and opinions of William Gowans. There was another eccentric book-dealer's shop in Nassau street kept by one John Doyle, who aimed so high in his profession as to post over his door a sign reading "The Moral Centre of the Intellectual Universe." This establishment was notably full of old editions of books of English history and controversial theology.
