In due time the train rolled out of Nuevo Laredo, and our friends were contemplating the scenery of northern Mexico. For the first fifty or sixty miles there was not much to contemplate, as the country consists of a plain covered with chaparral, and one mile of it is very much like any other. "A little of it goes a great ways," said Frank to Fred; and after a brief study of the cactus and mesquite landscape, the youths turned to their books or to observations upon the train and the passengers accompanying them.

As stated elsewhere, the National Railway is of three feet gauge, and therefore it was to be expected that the cars would be narrow and possibly inconvenient. But our friends found them roomy and comfortable; there was a parlor-car with reclining-chairs, for which an extra price was charged, and sleeping-cars all the way from Laredo to the City of Mexico, just as sleeping-cars are run on other lines.

WATCHING THE FRONTIER.

The passengers included several tourists like themselves, a few railway agents, some mysterious characters who could not be "placed," and six or eight men of business who cared nothing for scenery, politics, or anything else pertaining to Mexico, except the facilities for commerce and the duties upon imported goods. One of these individuals loudly denounced the protective duties in the Mexican tariff system, and declared that the country would never amount to anything until it abolished its restrictions upon importations and opened its markets to the world. In the discussion that followed, the fact was revealed that he was a citizen of the United States, and interested in manufactures; concerning the tariff system of his own country, he favored protection, as it encouraged American industries and was the only system under which the people who worked with their hands could make a living. Frank wanted to ask him why he favored one system for Mexico and another for the United States, but he modestly refrained from so doing; another passenger asked the question, but it remained unanswered; and to this day the youth has not been enlightened on the subject.

LANDSCAPE NEAR THE BORDER.

Among the passengers were several Mexicans, whose nationality was readily shown by their swarthy complexions and the peculiarities of their dress. They wore the sombrero, or wide-brimmed hat of the country, but it may here be remarked that of late years the American hat has come somewhat into fashion and is less unpopular than of yore. Some of them proved to be naturalized Mexicans rather than native born; one in particular was a jolly Irishman who had been thirty years in Mexico, spoke its language fluently, and had been so browned by the sun that his complexion was fully up to the national standard. He joined Doctor Bronson and the youths in conversation, and cordially invited them to make a break in their journey and visit his hacienda.
