Besides this, the port of St. Petersburg, during the lifetime of its founder, never was anything but a mere project. Peter's ships were moved from Kronslot to Kronstadt. Between St. Petersburg and Kronstadt the Neva was not, in those days, more than eight feet deep, and Manstein tells us that all ships built at Petersburg had to be dragged, by means of machines fitted with cables, to Kronstadt, where they received their guns. Once these had been taken on board, the vessels could not get upstream again. The port of Kronstadt was closed by ice for six months out of the twelve, and lay in such a position that no sailing-ship could leave it unless the wind blew from the east. There was so little salt in its waters that the ship timbers rotted in a very short time, and, besides, there were no oaks in the surrounding forests, and all such timber had to be brought from Kasan. Peter was so well aware of all these drawbacks that he sought and found a more convenient spot for his shipbuilding yards at Rogerwick, in Esthonia, four leagues from Revel. But here he found difficulty in protecting the anchorage from the effects of hurricanes and from the insults of his enemies. He hoped to insure this by means of two piers, built on wooden caissons filled with stones. He thinned the forests of Livonia and Esthonia to construct it, and finally, the winds and the waves having carried everything away twice over, the work was utterly abandoned. On the other hand, and from the very outset, the commercial activity of St. Petersburg was hampered by the fact that it was the Czar's capital. The presence of the court made living dear, and the consequent expense of labor was a heavy drawback to the export trade, which, by its nature, called for a good deal of manual exertion. According to a Dutch resident of that period, a wooden cottage, very inferior to that inhabited by a peasant in the Low Countries, cost from eight hundred to one thousand florins a year at St. Petersburg. A shopkeeper at Archangel could live comfortably on a quarter of that sum. The cost of transport, which amounted to between nine and ten copecks a pood (36.07 pounds), between Moscow and Archangel, five to six between Yaroslaff and Archangel, and three or four between Vologda and Archangel, came to eighteen, twenty, and thirty copecks a pood in the case of merchandise sent from any of these places to St. Petersburg. This accounts for the opposition of the foreign merchants at Archangel to the request that they should remove to St. Petersburg. Peter settled the matter in characteristic fashion, by forbidding any trade in hemp, flax, leather, or corn to pass through Archangel. This rule, though somewhat slackened, in 1714, at the request of the States-General of Holland, remained in force during the great Czar's reign. In 1718 hemp and some other articles of commerce were allowed free entrance into the port of Archangel, but only on condition that two-thirds of all exports should be sent to St.
