But if liberty has very little claim on the advertising columns of a newspaper in Buenos Ayres, there is a large set-off in favor of slavery. The papers teem with notices concerning that portion of the people who have the misfortune not to belong to themselves. And here it may be desirable to advert to a feature which is essential to the success of an advertisement in South America; it must be pictorial. Our own country newspapers, and most of the continental ones,--those of our Parisian friends in particular,--show us what can be done in this way; but they do not elaborate their subject after the manner of the Buenos-Ayreans. With them the advertisement must have a double chance; they who can read may enjoy the advantages of a liberal education in plain type;--they who have not been introduced to the schoolmaster may gather the meaning of the "noticia" from the greater or less striking resemblance of the object advertised to the woodcut which illustrates it. It is true, a difficulty may sometimes arise in the latter case, owing to an economical employment of the same block to represent a great variety of actions; the same slave is always in the attitude of a fugitive, whether he be described as running away with all his might, or quietly standing still to be sold; the same horse is always in a high trotting condition, whether he be supposed to career across the plain, or hold up a foot to be shod; the same bull has always his head bent down, with the same mischievous poke of the horns, whether he be advertised for slaughter or recommended for sport. A cook who might make a pudding with quick-lime instead of flour, and instead of a bath-brick send in a real one, would not accord with the notions of an English housewife. Female slaves who are to be sold, are represented as like to Atalanta, as the males are to Hippomenes. They, too, attired in a long night-gown, which has very much the look of impeding their flight, are always bolting with a bundle, which probably contains the bonnet they never appear in, or the shoes they are not supposed to wear. In like manner, if you wish to buy (_se desca comprar_) a slave, of either sex, you do so with your eyes open; for the great probability that the new purchase will vanish on the first favorable opportunity, is vividly get forth in the woodcut that speaks for all. The prices are tolerably high,--a boy, as we have seen, fetches nine hundred dollars; a woman-servant (_una criada_), fifteen hundred; and a man in the prime of his age,--for manual labor,--eighteen hundred, or two thousand. What a fortune Louis Napoleon might make, if he could establish a market-value for those whom he proscribes! M. Thiers would then be worth four hundred pounds!
