From the ample information recently furnished by the missionaries to the Directors, we learn that these two colonies of the British Crown contain together a population of Negro extraction amounting to half a million individuals; viz.: BRITISH GUIANA, 100,000; JAMAICA, 400,000. Besides these there are Indian Coolies, 28,800 in number, of whom GUIANA has 25,000. That province also contains 7,000 Indians, while Jamaica has its thousands of heathen Maroons. The ruling population of whites is 13,816 in Jamaica, and 2,000 in Guiana, or about 16,000 in all. This native population of half a million, just equal in number to the population of the single city of Calcutta or Canton, spread over an occupied territory of twelve thousand square miles, and situated only four thousand miles from England, enjoys the services of three hundred professed ministers of the Gospel; of whom a hundred and forty are supplied by Missionary Societies not connected with the established churches and supported by voluntary funds. The bulk of the population is nominally Christian, and has been for some years as well instructed in Christianity as an equal number of persons in the country parts of England. And doubtless it has been thus christianized the more fully because of the large supply of religious teachers furnished by the different sections of the Church of Christ. It is evident that the converts in Jamaica occupy a much higher position of physical and social comfort than those in GUIANA, and that the latter are not so well off as they were five-and-twenty years ago. While wages have fallen and prices have increased, it is evident that the moral influence of the 25,000 Coolies from India, with all their heathen vices, on the 100,000 Creoles has been exceedingly injurious. In neither colony has there been that thorough spiritual growth, that self-control, that self-reliance among the christian converts generally, which their best friends hoped for and thought they were able to find. This cannot be deemed unnatural, when it is considered that only thirty years have passed since the Act of Emancipation, and that ages of training will be needed before the moral taint of slavery is purified away.
