In the streets there is a constant movement. Carriages with liveried drivers, high-wheeled carts loaded with freight, curious little Japanese “kiosks,” in which walks a vendor of _dulces_, and _carigadores_ with loads upon their heads pass along in endless procession. I have seen pianos thus borne upon the heads of four men pass along the Avenida. Other heavy articles of furniture, and large panes of plate glass are carried in the same way. The old-fashioned, two-wheeled tilbury, so common here, whisks along at as lively a rate as the horse can go. Only one passenger dares ride in one of them, or a great commotion will be raised among the other tilbury drivers. The “fon-fon” of the automobile is constantly heard. A line of auto omnibuses is run along this avenue, and then some of the four hundred or more private autos will be in view at any time. Ice is delivered by automobile, for quick delivery is important in a hot climate when the price is three cents a pound. The automobile ambulance is sure to pass along, as it is always on the go, and then there are a number of auto deliveries, police hurry-up wagons, fire trucks, and even a street sprinkler propelled by gasoline. [Illustration: THE TREASURY BUILDING, RIO DE JANEIRO.] The police are omnipresent, and are to be found everywhere. There are three classes of these guardians of the public peace: the civil, the military and the mounted police. The former are under the prefect, and the military police, who wear a different uniform, are under the authority of the minister of war. The military police may be seen several times a day, marching along in large or small squads with a bugler to announce their coming. The civil police are more numerous but less conspicuous. It is said that there are oftentimes more or less serious conflicts of authority between the two police organizations. The military police department has a number of auto patrol wagons which are frequently seen on the streets. Whenever a call is sent to headquarters a wagon is loaded up with ten or a dozen officers, and is then sent pell-mell through the streets to the point of call, and frequently two wagons thus loaded will appear. Perhaps the occasion of the call is some harmless drunk (although drunkenness is not common), and it seems a joke to see such a formidable force appear upon such an occasion. At night, a policeman may be found upon almost any corner, and, if there is safety in numbers, then Rio de Janeiro is a very secure place in which to live.
