We passed many negro log-cabins, built where the ground was tolerably firm; but they were wretched-looking habitations, damp and miserable, many of them being mere hovels of a most unhealthy character. Though the rice fields, cotton, sugar, and tobacco plantations may be benefited by a constant supply of moisture, the damp heat produced by the sun's scorching rays in summer, as they fall upon this marshy ground, is exceedingly unhealthy, and produces yellow fever, which is often most fatal in the Southern States. Upon our arrival at Savannah--a beautiful city with plantations of orange and lemon trees growing in winter in the open air, and adorned with geraniums, creeping plants and various choice flowers--we accepted an invitation to the house of Mr. Charles Green, a Christian merchant; and during our short stay were entertained at his mansion most hospitably. Whilst there, Mr. Müller preached at the Baptist, Independent, Presbyterian, and Methodist Episcopal Churches, gave addresses to the girls of the Episcopal Orphan Asylum, of Whitefield's Orphanage in Georgia, and spoke to the children of the Preventive Home. Before our departure from Savannah, we took drives to Buonaventura Cemetery, to Plantation, and to Thunderbolt, and particularly noticed the luxuriant, but peculiar-looking, Spanish moss which attaches itself to the trunks and branches of the trees, and grows in great profusion all through the Southern States. Being of a grey colour, it is unlike European moss, and forms a long, deep fringe, a kind of sweeping, mournful drapery, which, as it is waved about by the wind, has so melancholy an appearance that it seems appropriate for cemeteries, where it is found in great abundance.
