I have received, little reference is made to any other emigrants than agricultural labourers, which is of course the class chiefly, if not exclusively wanted; I allude to this circumstance, because there are some classes at Sierra Leone which would supply no agricultural labourers, but only mechanics, schoolmasters, traders, boatmen, &c. The population of Sierra Leone, which in round numbers I take to be about 60,000, consists of about 1,200 Nova Scotia settlers, 1,200 Maroons, 50,000 liberated Africans, 7,600 Kroomen and strangers: 60,000. The Nova Scotians, or settlers, as we generally term them, would yield no field labourers, nor do I think that you would obtain any from the Maroons, though a large number of the latter would be very glad to be re-conveyed to their friends and relations at Jamaica, free of expense; a fair supply of mechanics, &c., might however be obtained from both classes. Of the liberated Africans, none of the more prosperous would, in my opinion, be inclined to emigrate, and at any rate they would not add to the number of the field labourers in the colonies. The people to whom I refer are hawkers, traders, and mechanics, and are generally drawn together and settled in Freetown and its neighbourhood, where they live in comfort and even luxury. It is to the remaining portion of this valuable body that we must principally look for emigrants, if we are to obtain them at all at Sierra Leone; and, if prudence and caution be used, I see no reason to doubt that a large number of them (quite as many as it will be proper for the colonies where they are now located to lose) may eventually be induced to remove to the West Indies. I would beg to propose that the four or five principal tribes of liberated Africans should be called upon, by means of influential persons of those tribes resident in Freetown, to select each two men in whom they have confidence; and those eight or ten delegates should be furnished with a passage to the West Indies and back, free of expense, in order that they may examine and ascertain for themselves the prospect which emigration offers. They should be used well on the voyage, should receive 2_l._ a month during their short absence, and their wives and families should be supported (a very trifling expense) during the same period. Let this plan be adopted and properly carried out, and I have no doubt whatever that it will be completely successful. The Kroomen, amongst whom I include the Fishmen, are so peculiar a race that they must always be considered by themselves. Their national peculiarities are very remarkable, and distinguish them almost as much from every other African tribe as they do from the Europeans. But it will be only necessary to notice those which affect them as emigrants. In the midst of a slaving district, they are never enslaved, and they navigate and work on board the Spanish and Portuguese slavers with perfect confidence and safety.
