 In 1858 , Louis Faidherbe , the governor of Senegal , inaugurated the <unk> boat that was capable of transporting 150 passengers , animals and all kinds of goods . The boat made ten crosses every day and the fares differed : five centimes for a person , 50 centimes for a horse , cow or camel , and two francs for a carriage . In less than a year it was obvious that this system was overrun and a second boat was introduced but with no success .
