"From the castle we went to the cathedral, which was built in the thirteenth century, and contains monuments to the memory of several of the kings and other great men of the country. It is proper to say here that the Catholic is the prevailing religion of Poland, and no doubt much of the hatred of Russians and Poles for each other is in consequence of their religious differences. By the latest figures of the population that we have at hand, Russian Poland contains about 3,800,000 Catholics, 300,000 Protestants, 700,000 Jews, and 250,000 members of the Greek Church and adherents of other religions, or a little more than 5,000,000 of inhabitants in all. Like all people who have been oppressed, the Catholics and Jews are exceedingly devout, and adhere unflinchingly to their religious faith. Churches and synagogues are numerous in Warsaw, as in the other Polish cities. In our ride through Warsaw we passed many shrines, and at nearly all of them the faithful were kneeling to repeat the prayers prescribed by their religious teachers. "From the cathedral we went to the citadel, which is on a hill in the centre of the city, and was built after the revolution of 1830. The expense of its construction was placed upon the people as a punishment for the revolution, and for the purpose of bombarding the city in case of another rebellion. From the walls of the citadel there is a fine view of considerable extent; but there is nothing in the place of special interest. The fort is constantly occupied by a garrison of Russian soldiers. It contains a prison for political offenders and a military court-house, where they are tried for their alleged offences. [Illustration: LAKE IN THE PARK.] "There are ten or twelve squares, or open places, in Warsaw, of which the finest is said to be the Saxon Square. It contains a handsome monument to the Poles who adhered to the Russian cause in the revolution of 1830. Some writers say it was all a mistake, and that the Poles whose memory is here preserved were really on their way to join the regiments which had declared in favor of the insurrection. "There are several handsome streets and avenues; and as for the public palaces and fine residences which once belonged to noble families of Poland, but are now mostly in Government hands, the list alone would be long and tedious. One of the finest palaces is in the Lazienki Park, and was built by King Stanislaus Poniatowski. It is the residence of the Emperor of Russia when he comes to Warsaw; but as his visits are rare, it is almost always accessible to travellers. We stopped a few minutes in front of the statue of King John Sobieski. There is an anecdote about this statue which the students of Russian and Polish history will appreciate. During a visit in 1850 the Emperor Nicholas paused in front of the statue, and remarked to those around him, 'The two kings of Poland who committed the greatest errors were John Sobieski and myself, for we both saved the Austrian monarchy.'
