We have thought proper to issue an Extra this morning, to inform our brethren and friends scattered abroad, of the ship Brooklyn leaving port last Wednesday, with about two hundred and thirty souls on board including men, women and children, together with three or four passengers. As it regards the getting up of this company of emigrants, we desire to give a brief and correct statement, for the benefit of all concerned. Some two months since, Elder S. Brannan was counselled by President O. Pratt, of this city, before leaving for the west, to charter a vessel, and take out a company of the saints to Oregon or California, and as soon as an opportunity offered, others would follow, and endeavor to get beyond the reach of persecution and oppression. Accordingly he obeyed the counsel. It is now about one month since he chartered the ship Brooklyn, Capt. Richardson, for twelve hundred dollars per month, besides paying the Port Charges. In this short space of time, by untiring assiduity, has he collected together the number heretofore stated, consisting of Farmers, Mechanics, &c., the greater part young and middle aged men and women.

The ship was expected to sail on the twenty fourth of twenty-sixth of January, but in order to have all things in readiness, and complete to make them comfortable she did not get off until last Wednesday. At two o'clock, P.M., she left her moorings and swung around the Pier into the stream. The Steamboat Sampson came along side, made fast to her, to pilot her down towards the narrows. As she left the wharf, it was a beautiful sight to behold. The noble ship with hundreds of ladies and gentlemen, lining her decks, friends, relations, &c., of the Emigrants. As she left the wharf, three hearty cheers were sent up, by the numerous crowd of gentlemen upon the Pier, which was as heartily returned, or responded to by those on board the ship. The day was propitious, the bright luminary of the heavens, had passed the zenith of his meridian glory, and was retiring in his stately robes toward the chamber of the West! Yet his oblique rays, as the noble ship passed down the bay, glistened with a propitious smile upon the bosom of the waves, which were now being parted asunder by the bow of the gallant ship. The order at length was given, for all those who did not belong to the ship's company, to get on board the steamboat preparatory to her casting off. Then there was a scene, we feel ourselves inadequate to describe. There you could behold the father bidding adieu to his only son perhaps forever. In another quarter you could see the mother embracing a daughter, and bidding each other farewell. While tears of parental and filial affection, trickled warmly down each other cheeks there, you could also behold the young man and young woman, without Father, Mother, Brother or Sister, (except those of their brothers and sisters endeared to them by the Gospel of the Son of God) willing to leave all behind, sacrificing all the comforts and enjoyments of the scenes of their childhood and former associations, for the father which they have embraced, and which they know is true, and are willing to die for the same. They have borne reproach, defamation, obloquy, and scorn, they have been persecuted (or at least the church they belong to,) mobbed, plundered, robbed, driven and murdered, and now they go as exiles, banished from the land of their nativity, the land that gave them birth, the land that is called the "asylum of the oppressed," the liberty that was obtained by the sweat, blood and tears of their fathers, and bequeathed to them as the greatest legacy they could have, has taken its flight and gone, when it comes to be exercised in their behalf. But to return from my digression after bidding a last farewell, the steamboat was disengaged, and as she rounded to return to the city, three hearty cheers were given by them on board, the steamboat consisting of ladies and gentlemen, (among whom were doctors, clergymen, merchants, ship owners, clerks, &c.,) which was immediately responded to, by three more, from those on board the ship; she then passed on in a beautiful and majestic style, with her topsails and jib spread to the breeze which was blowing direct from the N.N.W., amid the waving of handkerchiefs, hats, &c., until she was finally lost in the distance. Farewell our brethren and sisters in the Lord; we commit you to the care of him whose ye are, and whose name ye have confessed. You have our prayers and hearty wishes, that He who rules the destinies of Empires and Kingdoms, may send his Angel before you. Soothe the howling tempest, stay the rolling billows, vanquish the fell destroyer, and guide you safe to your destined haven. Go then noble ship, with thy noble crew, spread thy canvass to the winds of heaven, and bear them swiftly to their destined port, where no pious "(christian)" thirsts for gold nor seeks the blood of innocence. The prayers of the Saints of God shall be offered up, for those thou carryest, and that, ere long, thou mayest return and bear another company to the same desired spot. The ship is nearly new, of four hundred and fifty tons measurement; she is well loaded with Agricultural and Mechanical tools enough for eight hundred men, consisting of ploughs, hoes, forks, shovels, spades, plough irons, scythes, sickles, nails, glass, Blacksmith's tools, Carpenters, do. Millwrights, do. three Grain mills for grinding, grain, turning lathes, saw mill irons, grindstones, one printing press and type, paper, stationary, school books consisting of spelling books, sequels, history, arithmetic, astronomy, grammar, Morse's Atlas and Geography, Hebrew Grammar and Lexicon, Slates, &c., &c. Also, dry goods, twine, &c., brass, copper, iron, tin and crockery ware, with provisions and water enough for a six or seven months voyage. They have also on board two new milch cows, forty of fifty pigs, besides fowls, &c. They have every thing on board to make them comfortable; there is thirty-two state rooms on board, with decent births, where they can spread their mattress, and repose content. -- They went off joyful and in high spirits; although they have a long journey before them some fifteen thousand miles to perform, they purpose touching at the Sandwich Islands, and so on to Oregon or California.

The morning before the Ship's sailing, a gentleman of Brooklyn, J. M. Vancott, (a lawyer of great and noted celebrity I understand) presented the emigrants through Mr. Brannan, with one hundred and seventy nine volumes of Harper's Family Library: may the Lord reward him for his kindness, towards a persecuted and oppressed, yet upright and virtuous people. -- And not only him, but all those of our friends who have been kind in assisting us, and was not ashamed of us although as the Apostles were "every where spoken evil against," may our Heavenly Father bless such, as much as they do it with a desire to do good, and not from selfish motives is our desire.
