History The history of the Panama Canal goes back to 16th century. After realizing the riches of Peru, Ecuador, and Asia, and counting the time it took the gold to reach the ports of Spain, it was suggested c.1524 to Charles V, that by cutting out a piece of land somewhere in Panama, the trips would be made shorter and the risk of taking the treasures through the isthmus would justify such an enterprise. A survey of the isthmus was ordered and subsequently a working plan for a canal was drawn up in 1529. The wars in Europe and the thirsts for the control of kingdoms in the Mediterranean Sea simply put the project on permanent hold. In 1534 a Spanish official suggested a canal route close to that of the now present canal. Later, several other plans for a canal were suggested, but no action was taken. The Spanish government subsequently abandoned its interest in the canal. In the early 19th century the books of the German scientist Alexander von Humboldt revived interest in the project, and in 1819 the Spanish government formally authorized the construction of a canal and the creation of a company to build it. The discovery of gold in California in 1848 and the rush of would-be miners stimulated Americas interest in digging the canal Various surveys were made between 1850 and 1875 showed that only two routes were practical, the one across Panama and another across Nicaragua. In 1876 an international company was organized; two years later it obtained a concession from the Colombian government to dig a canal across the isthmus. The international company failed, and in 1880 a French company was organized by Ferdinand Marie de Lesseps, the builder of the Suez Canal. In 1879, de Lesseps proposed a sea level canal through Panama. With the success he had with the construction of the Suez Canal in Egypt just ten years earlier, de Lesseps was confident he would complete the water circle around the world. Time and mileage would be dramatically reduced when travelling from the Atlantic to the Pacific ocean or vice versa. For example, it would save a total of 18,000 miles on a trip from New York to San Francisco. Although de Lesseps was not an engineer, he was appointed chairman for the construction of the Panama Canal. Upon taking charge, he organized an International Congress to discuss several schemes for constructing a ship canal. De Lesseps opted for a sea-level canal based on the construction of the Suez Canal. He believed that if a sea-level canal worked when constructing the Suez Canal, it must work for the Panama Canal. In 1899 the US Congress created an Isthmian Canal Commission to examine the possibilities of a Central American canal and to recommend a route. The commission first decided on a route through Nicaragua, but later reversed its decision. The Lesseps company offered its assets to the United States at a price of $40 million. The United States and the new state of Panama signed the Hay-Bunau-Varilla treaty, by which the United States guaranteed the independence of Panama and secured a perpetual lease on a 10-mile strip for the canal. Panama was to be compensated by an initial payment of $10 million and an annuity of $250,000, beginning in 1913. This strip is now known as the Canal Zone. The length of the Panama Canal is approximately 51 miles. A trip along the canal from its Atlantic entrance would take you through a 7 mile dredged channel in Limón Bay. The canal then proceeds for a distance of 11.5 miles to the Gatun Locks. This series of three locks raise ships 26 metres to Gatun Lake. It continues south through a channel in Gatun Lake for 32 miles to Gamboa, where the Culebra Cut begins. This channel through the cut is 8 miles long and 150 metres wide. At the end of this cut are the locks at Pedro Miguel. The Pedro Miguel locks lower ships 9.4 metres to a lake which then takes you to the Miraflores Locks which lower ships 16 metres to sea level at the canals Pacific terminus in the bay of Panama.
