Having planted himself one day in front of a bookseller's shop with great care, to avoid being broken, he began to talk to the owner, and said, "This trade would please me greatly, were it not for one fault that it has." The bookseller inquiring what that might be, Rodaja replied, "It is the tricks you play on the writers when you purchase the copyright of a book, and the sport you make of the author if, perchance, he desire to print at his own cost. For what is your method of proceeding? Instead of the one thousand five hundred copies which you agree to print for him, you print three thousand; and when the author supposes that you are selling his books, you are but disposing of your own." One of those men who carry sedan-chairs, once standing by while Rodaja was enumerating the faults committed by various trades and occupations, remarked to the latter, "Of us, Señor Doctor, you can find nothing amiss to say." "Nothing," replied Rodaja, "except that you are made acquainted with more sins than are known to the confessor; but with this difference, that the confessor learns them to keep all secret, but you to make them the public talk of the taverns." A muleteer who heard this, for all kinds of people were continually listening to him, said aloud, "There is little or nothing that you can say of us, Señor Phial, for we are people of great worth, and very useful servants to the commonwealth." To which the man of glass replied, "The honour of the master exalts the honour of the servant. You, therefore, who call those who hire your mules your masters, see whom you serve, and what honour you may borrow from them; for your employers are some of the dirtiest rubbish that this earth endures. "Once, when I was not a man of glass, I was travelling on a mule which I had hired, and I counted in her master one hundred and twenty-one defects, all capital ones, and all enemies to the human kind. All muleteers have a touch of the ruffian, a spice of the thief, and a dash of the mountebank. If their masters, as they call those they take on their mules, be of the butter-mouthed kind, they play more pranks with them than all the rogues of this city could perform in a year. If they be strangers, the muleteers rob them; if students, they malign them; if monks, they blaspheme them; but if soldiers, they tremble before them. These men, with the sailors, the carters, and the arrieros or pack carriers, lead a sort of life which is truly singular, and belongs to themselves alone. "The carter passes the greater part of his days in a space not more than a yard and a half long, for there cannot be much more between the yoke of his mules and the mouth of his cart. He is singing for one half of his time, and blaspheming the other; and if he have to drag one of his wheels out of a hole in the mire, he is more aided, as it might seem, by two great oaths than by three strong mules.
