Green Castle lies about three miles south-east from St. John's, and contains 940 acres. The mansion stands on a rocky cliff; overlooking the estate, and commanding a wide view of the island. In one direction spreads a valley, interspersed with fields of sugar-cane and provisions. In another stretches a range of hills, with their sides clad in culture, and their tops covered with clouds. At the base of the rock are the sugar Houses. On a neighboring upland lies the negro village, in the rear of which are the provision grounds. Samuel Bernard, Esq., the manager, received us kindly. He said, he had been on the island forty-four years, most of the time engaged in the management of estates. He is now the manager of two estates, and the attorney for six, and has lately purchased an estate himself. Mr. B. is now an aged man, grown old in the practice of slave holding. He has survived the wreck of slavery, and now stripped of a tyrant's power, he still lives among the people, who were lately his slaves, and manages an estate which was once his empire. The testimony of such a man is invaluable. Hear him. 1. Mr. B. said, that the negroes throughout the island were very peaceable when they received their freedom. 2. He said he had found no difficulty in getting his people to work after they had received their freedom. Some estates had suffered for a short time; there was a pretty general fluctuation for a month or two, the people leaving one estate and going to another. But this, said Mr. B., was chargeable to the _folly_ of the planters, who _overbid_ each other in order to secure the best hands and enough of them. The negroes had a _strong attachment to their homes_, and they would rarely abandon them unless harshly treated. 3. He thought that the assembly acted very wisely in rejecting the apprenticeship. He considered it absurd. It took the chains partly from off the slave, and fastened them on the master, _and enslaved them both_. It withdrew from the latter the power of compelling labor, and it supplied to the former no incentive to industry. He was opposed to the measures which many had adopted for further securing the benefits of emancipation.--He referred particularly to the system of education which now prevailed. He thought that the education of the emancipated negroes should combine industry with study even in childhood, so as not to disqualify the taught for cultivating the ground. It will be readily seen that this prejudice against education, evidently the remains of his attachment to slavery, gives additional weight to his testimony.
