Such are some of the favorable influences of the Colonization Society on the general interests of the colored population. We might enumerate many more, and say many things to obviate the objections which some have urged against the Society, but time will not permit. We conclude the argument, therefore, by urging all the friends of colonization diligently to consider the testimony concerning this enterprise, and to prepare themselves to vindicate it against the attacks of its enemies, and to commend it to the confidence and support of the community. The state of feeling at the present time towards the Colonization Society requires that something should be done. Its enemies, though feeble, are clamorous, and if nothing is done to check their influence, may deceive some portion of the people. Let, then, the friends of colonization awake and prepare themselves for a discussion, from which they have everything to hope. The enterprise will go forward--the colony at Liberia will be sustained, and the society will receive, as it deserves, the universal and cordial gratitude and support of every portion of the community. PRESENT STATE OF THE COLONY. The following letters from a respectable emigrant, will farther show the present condition of the settlements: FROM LIBERIA.--We are happy to announce the arrival at Liberia of the ship Jupiter, Captain Peters, which vessel sailed from Norfolk at the close of October last, and for whose safety serious apprehensions were entertained. Capt. Peters called at the Cape de Verds, and at several places on the African coast, before he touched at Monrovia, at which port he arrived on the 7th of March. The Rev. Melvin B. Cox, the gentleman sent out by the Missionary Society of the Methodist Episcopal Church, was a passenger in this ship, and was in good health on the 8th of March, the date of our last advices. Some of our readers will probably recollect that in December last we noticed the departure from Norfolk of the brig Roanoke, Capt. Hatch, for Monrovia. In this vessel an interesting colored family, named Reynolds, from Onondaga county, were passengers. The Onondaga Standard, of the 20th May, contains two letters from Mr. Reynolds, which are subjoined. The letters corroborate the favorable accounts which have been given of Liberia. MONROVIA, LIBERIA, MARCH 1, 1833. MR. COPP:--SIR: Mindful of your request that I should inform you of my safe arrival, and how I am pleased with the country, I improve the opportunity presented by return of Roanoke to write a short letter. We had a pleasant passage of 42 days from land to land, and by the attention of Capt. Hatch, were rendered quite comfortable. Not one of my family were sea-sick a day; and by the favor of God our health still continues, though we do not expect to escape a visit of the fever-and-ague, which scarcely ever passes by new comers without a call.
