THE POLICE-OFFICE AT MENDOZA.

It was necessary to have a passport for the frontier between Chili and the Argentine Republic, and accordingly they paid a visit to the police-office, accompanied by their German friend. Frank presented the necessary papers, which he obtained at Buenos Ayres, and there could be no reason for his detention; but it took fully half an hour to convince the police-master that no harm would come to either country by allowing the youth and his servant to pass into Chili. Tourists are so rare in this part of the world that the authorities cannot easily believe a man will undertake the hardships of a journey over the Andes, when he has nothing to gain by it and considerable money to pay out. Looking upon travel as purely a matter of business, they are quite in sympathy with the Chinese merchant who was invited to an English dancing-party, and wonderingly asked his host, "Can't you get your servants to do that for you?"

In a light wagon, hired for the ride to the foot of the mountains, where the mules were waiting, Frank set out, accompanied by Manuel, who was seated at the driver's side and had a special eye for the baggage, that lay below him. The wagon was the property of an enterprising citizen, who had imported it from the United States since the opening of the railway, and he was contemplating a purchase of half a dozen similar vehicles during the following year. It had stout springs, and was well adapted to the roads around Mendoza, which are none of the best. Frank was given the choice of this wagon or a birlocha, and immediately chose the former. And what do you suppose a birlocha is?

THE BIRLOCHA.

It resembles an old-fashioned chaise, and is drawn by two horses, one between the shafts and one outside (on the left side), and fastened by a single trace of rawhide or half-tanned leather. The driver is mounted on the outside horse, and there are seats over the wheels for two passengers. In hilly country a man follows with a third horse, which is attached to the right side of the vehicle when a steep slope is to be ascended. Frank took a ride through the streets of Mendoza in one of these vehicles, enough to satisfy himself that the wagon was preferable for the drive across the plain between the city and the foot of the mountains. Had he been in the hilly region he would have chosen the birlocha, for its greater facility in turning sharp corners.
