While in Savannah, I paid a visit to Bonaventure, formerly a country seat of Governor Tatnall, but now abandoned. A pleasant drive of a mile or two, through a budding forest, took us to the place, which is now itself almost grown up into forest. Cedars and other shrubs hide the old terraces of the garden, which is finely situated on the high bank of a river. Trees of various kinds have also nearly filled the space between the noble avenues of live-oaks which were planted around the mansion. But these oaks—never saw finer trees—certainly I never saw so many majestic and venerable trees together. I looked far down the immense arches that overshadowed the broad passages, as high as the nave of a Gothic cathedral, apparently as old, and stretching to a greater distance. The huge boughs were clothed with gray moss, yards in length, which clung to them like mist, or hung in still festoons on every side, and gave them the appearance of the vault of a vast vapory cavern. The cawing of the crow and the scream of the jay, however, reminded us that we were in the forest. Of the mansion there are no remains; but in the thicket of magnolias and other trees, among rosebushes and creeping plants, we found a burial-place with monuments of some persons to whom the seat had belonged. Savannah is more healthy of late years than it formerly was. An arrangement has been made with the owners of the plantations in the immediate vicinity by which the culture of rice has been abandoned, and the lands are no longer allowed to be overflowed within a mile from the city. The place has since become much less subject to fevers than in former years. I left, with a feeling of regret, the agreeable society of Savannah. The steamboat took us to St. Mary's, through passages between the sea-islands and the main-land, similar to those by which we had arrived at Savannah. In the course of the day, we passed a channel in which we saw several huge alligators basking on the bank. The grim creatures slid slowly into the water at our approach. We passed St. Mary's in the night, and in the morning we were in the main ocean, approaching the St. John's, where we saw a row of pelicans standing, like creatures who had nothing to do, on the sand. We entered the majestic river, the vast current of which is dark with the infusion of the swamp turf, from which it is drained. We passed Jacksonville, a little town of great activity, which has sprung up on the sandy bank within two or three years. Beyond, we swept by the mouth of the Black Creek, the water of which, probably from the color of the mud which forms the bed of its channel, has to the eye an ebony blackness, and reflects objects with all the distinctness of the kind of looking-glass called a black mirror. A few hours brought us to Picolata, lately a military station, but now a place with only two houses. Letter XIII. St. Augustine. St. Augustine, East Florida, _April 2, 1843._
