In the old town, which contains the government-house and Jesuits' College, the streets are not so regularly and_ well built as in the new . The Place d'Armes, a fine quadrangular space, lies between them . To the right of the governor's house is Mount Ceperon, on which stand Fort St Michel, the marine barracks, the signal station and the lighthouse . Here, too, are the capacious reservoirs for the water-supply of the town, the source of which is a lake to the south of the island . The harbour is shallow at its entrance, and craft drawing more than 14 ft. are obliged to anchor 6 m. from the town . There is no dock for the repair of vessels; but there are two quays at the town . The principal exports of Cayenne are gold, cocoa, phosphates, hides, woods and spices . The imports are French wines, spirits and liqueurs; silk and cotton stuffs, tobacco, hardware, glass, earthenware, clothing, preserved meat, fish, and vegetables, maize, flour, hay, bran, oils and cattle .

There is a

regular mail service between Cayenne and Martinique once a month . Cayenne is the seat of the government of French Guiana, and was formerly a penal settlement for political offenders . Food as well as clothing is exorbitantly dear, the only cheap articles of consumption being bread and French wines . The temperature of Cayenne is between 76° and 88° Fahr. throughout the year; but the heat is tempered by easterly winds . Between December and March a north wind blows, unfavourable to weak constitutions . Yellow and other fevers often attack the inhabitants of the town, but the climate, though moist, is as a whole healthy .
