The cause of African colonization never was more prosperous or more promising than at the present moment. In all its departments this is the case; it is so abroad, and it is so at home. In regard to the Colony,--which, after all, is at once the best evidence of the progress of the Parent Institution, and the surest test of its principles,--the authentic and indisputable accounts which reach us from every quarter, must be admitted as sufficient to satisfy all reasonable and candid minds, not only of the actual prosperity of the present settlements, but of the practicableness of the colonial scheme on the larger and nobler scale always anticipated, more or less, by the advocates of the cause. Instances of mismanagement, as well as misfortune, doubtless have occurred; it would be indeed a new thing in the history of colonization, as well as in the conduct of all other systems whose progress depends on the labor of men, if there had not been such instances. But, not to mention that these misfortunes were mostly in their nature such as cannot be repeated, and such as, in all events, only past experience has been necessary to prevent for the future,--and not to insist on the credit fairly due to the Society, for frankly acknowledging the mistakes we allude to, and for always manifesting a readiness to submit to instruction, and to act vigorously and promptly in the correction of errors,--who, among the foes of the Institution, will at the worst, undertake to deny that a degree of success has, on the whole, attended its efforts on the African coast, to which, in the language of Mr. Cresson, “the annals of Colonization may be triumphantly challenged for a parallel?” Since the date of this declaration of our able friend in England, the population of the Colony has been increased by more than one half, nearly eight hundred emigrants having been carried out during the year immediately preceding the first of January last. Other accessions to its establishments, during the same period, are among the most important which have taken place. Very satisfactory arrangements have been effected by the Colonial Agent for the settlement of Grand Bassa, a tract of country which, in regard to its climate, soil, situation, and productions of all kinds, is proved to be inferior to no other district on the whole coast: a valuable territory on the western banks of the St. John’s river, with four large islands within the river, additional to the immense tract purchased by Mr. Ashmun, have not only been peaceably obtained of the natives, but the latter have pledged themselves,--such seems to be their anxiety to trade and associate with the Liberians,--to erect suitable buildings, at their own expense, for the accommodation of the first emigrants. At the time we are writing, this promising settlement is doubtless already commenced.
