A mechanical drosky, invented by a Siberian peasant, has an apparatus which records the time and distance travelled, besides playing several tunes. Near Peter's sledge stand two or three diminutive carriages for the use of the royal children. In another room are kept the harnesses and trappings used for the imperial state carriages, with liveries for eight hundred men. In one set, each horse has to carry about one hundred and twenty pounds. The carriages are all in the second story of the building, and there is a kind of platform elevator, by which they are hoisted up. The state coaches are used at the coronation of the emperors, and this ceremonial always takes place at Moscow, whither they have to be transported, though, since the railroad was completed, this is not so difficult a matter as formerly. The students walked on the quay to the vast Admiralty building, and went into the Naval Museum, in which there are models of all kinds of boats and vessels, which were full of interest to the nautical young gentlemen. This completed the labors of the day, and the company returned to Cronstadt in the steamer. At the usual hour on the following morning they embarked again, and were soon landed at Peterhoff, which is sometimes called the Versailles of Russia, on account of the number and variety of the fountains in the palace grounds. The place is on the south side of the broad bay inside of Cronstadt, and about ten miles distant from it. It is a favorite summer resort of the people from the capital, steamers plying frequently between the two places. It has a great many attractions, the principal of which is the palace, erected in 1720, under the direction of Peter the Great, on an elevation of sixty feet,--a considerable hill in Russia,--and the magnificent grounds, laid off in parks, lawns, terraces, groves, and gardens. The buildings are extensive, but not very elegant outside. The apartments contain a great many paintings, including portraits of three hundred and sixty-eight beautiful young girls, from fifty different provinces. The rooms for use contain the usual gilded chairs, sofas, tables, and other furniture, which soon become very tiresome to the traveller in Europe, for they are about the same thing in all the palaces, and, to a republican, would have a cheap look, if it were not for the silks, velvets, and brocade with which they are upholstered.
