Amid the signs of the breaking down of barriers, we may mention the Emperor Nicholas letting his daughter pass from the Greek to the Roman church, for the sake of marrying her to the Austrian prince. Again, similarity between him and us: he, too, is shameless; for while he signs this marriage contract with one hand, he holds the knout in the other to drive the Roman Catholic Poles into the Greek church. But it is a fatal sign for his empire. 'Tis but the first step that costs, and the Russians may look back to the marriage of the Grand Duchess Olga, as the Chinese will to the cannonading of the English, as the first sign of dissolution in the present form of national life. A similar token is given by the violation of etiquette of which Mr. Polk is accused in his message. He, at the head of a government, speaks of governments and their doings straightforward, as he would of persons, and the tower, stronghold of the idea of a former age, now propped up by etiquettes and civilities only, trembles to its foundation. Another sign of the times is the general panic which the decay of the potato causes. We believe this is not without a providential meaning, and will call attention still more to the wants of the people at large. New and more provident regulations must be brought out, that they may not again be left with only a potato between them and starvation. By another of these whimsical coincidences between the histories of Aristocracy and Democracy, the supply of _truffles_ is also failing. The land is losing the "nice things" that the queen (truly a young queen) thought might be eaten in place of bread. Does not this indicate a period in which it will be felt that there must be provision for all--the rich shall not have their truffles if the poor are driven to eat nettles, as the French and Irish have in bygone ages? The poem of which we here give a prose translation lately appeared in Germany. It is written by Moritz Hartmann, and contains the _gist_ of the matter. MISTRESS POTATO. There was a great stately house full of people, who have been running in and out of its lofty gates ever since the gray times of Olympus. There they wept, laughed, shouted, mourned, and, like day and night, came the usual changes of joys with plagues and sorrows. Haunting that great house up and down, making, baking, and roasting, covering and waiting on the table, has there lived a vast number of years a loyal serving maid of the olden time--her name was Mrs. Potato. She was a still, little, old mother, who wore no bawbles or laces, but always had to be satisfied with her plain, every-day clothes; and unheeded, unhonored, oftentimes jeered at and forgotten, she served all day at the kitchen fire, and slept at night in the worst room. When she brought the dishes to table she got rarely a thankful glance; only at times some very poor man would in secret shake kindly her hand.
