On May 4, 1818, he left Black River for England, and ten days later he was committed to a watery grave, having succumbed to yellow fever, which had broken out on board the _Sir Godfrey Webster_. He died in the arms of the faithful Tita who was afterwards present at Byron’s death. The following is Lewis’s description of Cornwall great house as it then was: The houses here are generally built and arranged to one and the same model. My own is of wood, partly raised upon pillars; it consists of a single floor: a long gallery, called a piazza, terminated at each end by a square room, runs the whole length of the house. On each side of the piazza is a range of bedrooms, and the porticoes of the two fronts form two more rooms, with balustrades, and flights of steps descending to the lawn. The whole house is virandoed with shifting Venetian blinds to admit air; except that one of the end rooms has sash-windows on account of the rains, which, when they arrive, are so heavy, and shift with the wind so suddenly from the one side to the other, that all the blinds are obliged to be kept closed; consequently the whole house is in total darkness during their continuance, except the single sash-windowed room. There is nothing underneath except a few store-rooms and a kind of waiting-hall; but none of the domestic negroes sleep in the house, all going home at night to their respective cottages and families. Cornwall House itself stands on a dead flat, and the works are built in its immediate neighbourhood, for the convenience of their being the more under the agent’s personal inspection (a point of material consequence with them all, but more particularly for the hospital). This dead flat is only ornamented with a few scattered bread-fruit and cotton trees, a grove of mangoes, and the branch of a small river, which turns the mill. Several of these buildings are ugly enough; but the shops of the cooper, carpenter and blacksmith, some of the trees in their vicinity, and the negro huts, embowered in shrubberies and groves of oranges, plantains, cocoas and pepper-trees, would be reckoned picturesque in the most ornamented grounds. A large spreading tamarind fronts me at this moment and overshadows the stables, which are formed of open wickerwork; and an orange tree, loaded with fruit, grows against the window at which I am writing.
