On the confines of Livonia and Esthonia, and to the eastward of the province of Novogorod, lies the great lake Peipus, which receives the waters of the river Velika, from out of the middle of Livonia, and gives rise in its northern part to the river Naiova, that washes the walls of the town of Narva, near which the Swedes gained their famous victory. This lake is upwards of thirty leagues in length, and from twelve to fifteen in breadth. It was necessary to keep a fleet there, to prevent the Swedish ships from insulting the province of Novogorod; to be ready to make a descent upon their coasts, and above all, to be a nursery for seamen. Peter employed the greatest part of the year 1701, in building on this lake an hundred half gallies, to carry about fifty men each; and other armed barks were fitted out on the lake Ladoga. He directed all these operations in person, and set his new sailors to work: those who had been employed in 1697, at the Palus Mæotis were then stationed near the Baltic. He frequently quitted those occupations to go to Moscow, and the rest of the provinces, in order to enforce the observance of the late customs he had introduced, or to establish new ones. Those princes who have employed the leisure moments of peace in raising public works, have acquired to themselves a name: but that Peter, just after his misfortune at Narva, should apply himself to the junction of the Baltic, Caspian, and the Black seas, by canals, has crowned him with more real glory than the most signal victory. It was in the year 1702, that he began to dig that deep canal, intended to join the Tanais and the Wolga. Other communications were likewise to be made, by means of lakes between the Tanais and the Duna; whose waters empty themselves into the Baltic, in the neighbourhood of Riga. But this latter project seemed to be still at a great distance, as Peter was far from having Riga in his possession. While Charles was laying all Poland waste, Peter caused to be brought from that kingdom, and from Saxony, a number of shepherds, with their flocks, in order to have wool fit for making good cloth; he likewise erected manufactories of linen and paper: gave orders for collecting a number of artificers; such as smiths, braziers, armourers, and founders, and the mines of Siberia were ransacked for ore. Thus was he continually labouring for the embellishment and defence of his dominions. Charles pursued the course of his victories, and left a sufficient body of troops, as he imagined, on the frontiers of the czar's dominions, to secure all the possessions of Sweden. He had already formed a design to dethrone Augustus, and afterwards to pursue the czar with his victorious army to the very gates of Moscow.
