In *L'isthme de Panama*, Michel Chevalier presents a comprehensive geographical and historical examination of the feasibility of piercing the Isthmus of Panama to create a maritime passage between the Atlantic and Pacific Oceans. The work begins by establishing the immense scale of the American landmass, noting that the isthmus stretches over 2,300 kilometers, yet possesses five specific points where the mountain chain breaks or narrows significantly. These locations include the Isthmus of Tehuantepec, the Bay of Honduras, Lake Nicaragua, the Isthmus of Panama proper, and the Isthmus of Darien. Chevalier contrasts the formidable, continuous barrier of the Andes and Rocky Mountains elsewhere with the more manageable topography of the Panamanian isthmus. He argues that while the region is mountainous, the specific points of interest do not reach heights insurmountable by engineering, particularly near the Bay of Mandinga and the Boca del Toro. The text reviews historical attempts, from Columbus's initial voyages to the failed efforts of the Spanish crown, which neglected these vital transport routes due to a mix of policy and negligence. Chevalier highlights the existing infrastructure, such as the old road paved by Francisco Pizarro and the navigable Chagres River, which facilitated travel between the oceans via mule trains and pirogues. He critiques the Spanish government's failure to develop these routes, leading to inefficient trade routes that circumvented the isthmus entirely. The author also discusses the hydrological differences between the two oceans, noting the significant tidal variations at Panama compared to the minimal tides at Chagres. Through detailed leveling operations conducted by engineers like Lloyd and Falmarc, Chevalier refutes earlier pessimistic assessments, demonstrating that a canal or railway could be constructed with manageable gradients. The book serves as both a geographical guide and a persuasive argument for the strategic and economic necessity of connecting the two oceans, anticipating the eventual realization of the Panama Canal project.
