Neva
Neva, the river of St. Petersburg, flows from Lake Ladoga into the Gulf of Finland, its whole course being only about 40 miles. It is about two-thirds of a mile wide in the broadest part, and carries an immense volume of water. It is frozen over throughout the winter. The Ladoga Canal connects it with the Volga.
