As to the success of the Missions in the two colonies, accurate statistics are not at hand; but from what has been stated, it appears that for the first 30 years of their existence, the increase in Liberia has been more than double that in Sierra Leone. With these facts before us, it becomes a matter of great moment to determine what has been the cause of the difference in the prosperity of the two Colonies. It can not be attributed to any great inequality between their emigrants, as, mostly, they had an identity of origin; nor to any great difference among the natives, as the diversity of languages in the one, would be balanced by the greater degradation of the other.[40] Then, as there was, originally, no material difference in their populations, the greater success of the citizens of Liberia, in maintaining their civil and religious institutions, can not be a result of their attainments under the slavery of the United States, but must be a consequence of their intellectual advancement after reaching the Colony. Neither can the cause of the difference be found in the educational and religious institutions of the two Colonies, as these are identical in both. The difference, therefore, can exist, only, in the greater extent of the social and civil privileges which the Liberians have enjoyed in their form of government. Look at the facts. From the time Sierra Leone passed out of the hands of Granville Sharp, the colored people have been excluded from participating in the government. The offices have been filled with white men, who reside among the negroes, in the position and attitude of a superior race, born to command; while the colonists are made to feel that their destiny is to obey: hence, in prosecuting their education, the youth of that Colony have had their mental powers dwarfed, by the absence of the stimulants which the hope of social and political advancement afford. In Liberia the policy has been the reverse. From the beginning, the minor offices were held by the colored men; and for the past twelve years, no white man has held any office, civil or military, in the Colony. Thus, the posts of honor have been open to the competition of every Liberian; and, catching the progressive spirit of the age, the colonists have aspired to the dignity of Nationality; have established an Independent Republic; and have progressed, in their civil and religious relations, with a rapidity doubly as great as Sierra Leone.[41]
