The incident led to a conversation upon the Russian tariff system, which is based upon the most emphatic ideas in favor of protection to home industries. As it is no part of our intention to discuss the tariff in this volume, we will omit what was said upon the subject, particularly as no notes were taken by either Frank or Fred. In due time the train on the Russian side of the station was ready to receive the travellers, and they took their places in one of the carriages. It needed only a glance to show they had crossed the frontier. The Austrian uniform disappeared, and the Russian took its place; the Russian language was spoken instead of German; the carriages were lettered in Russian; posts painted in alternate stripes of white and black (the invention of the Emperor Paul about the beginning of the present century), denoted the sovereignty of the Czar; and the dress of many of the passengers indicated a change of nationality. [Illustration: SCENE ON THE RAILWAY.] The train rolled away from Granitsa in the direction of Warsaw, which was the next point of destination of our friends. The country through which they travelled was not particularly interesting; it was fairly though not thickly settled, and contained no important towns on the line of the railway, or any other object of especial interest. Their English acquaintance said there were mines of coal, iron, and zinc in the neighborhood of Zombkowitse, where the railway from Austria unites with that from eastern Germany. It is about one hundred and eighty miles from Warsaw; about forty miles farther on there was a town with an unpronounceable name, with about ten thousand inhabitants, and a convent, which is an object of pilgrimage to many pious Catholics of Poland and Silesia. A hundred miles from Warsaw they passed Petrikau, which was the seat of the ancient tribunals of Poland; and then, if the truth must be told, they slept for the greater part of the way till the train stopped at the station in the Praga suburb of Warsaw, on the opposite bank of the Vistula. [Illustration: SHUTES FOR LOADING COAL ON THE RAILWAY.] As they neared the station they had a good view of Warsaw, on the heights above the river, and commanded by a fortress which occupies the centre of the city itself. Alighting from the train, they surrendered their passports to an official, who said the documents would be returned to them at the Hôtel de l'Europe, where they proposed to stop during their sojourn within the gates of Warsaw. Tickets permitting them to go into the city were given in exchange for the passports, and then they entered a rickety omnibus and were driven to the hotel. It was late in the afternoon when they climbed the sloping road leading into Warsaw, and looked down upon the Vistula and the stretch of low land on the Praga side. Fred repeated the lines of the old verse from which we have already quoted, and observed how well the scene is described in a single couplet:
