Book excerpt: Ledyard's Siberian journals recount a harrowing journey through Russia under the rule of Catherine the Great, while his diary from Alexandria and Cairo provides a brilliant and rare account of Egypt before Napoleon's invasion. Finally, Ledyard's correspondence sheds light on pre-revolutionary Paris and on his friendships with the Marquis de Lafayette, Benjamin Franklin, and Sir Joseph Banks. In his short life, John Ledyard traveled farther than any American had before."--Jacket.
