The prisoners, (Gibbs and Wansley,) were brought to trial at the February term of the United States Court, holden in the city of New York; when the foregoing facts being satisfactorily proved, they were pronounced guilty, and on the 11th March last, the awful sentence of the law was passed upon them in the following affecting and impressive manner:--The Court opened at 11 o'clock, Judge Betts presiding. A few minutes after that hour, Mr. Hamilton, District Attorney, rose and said--May it please the Court, Thomas J. Wansley, the prisoner at the bar, having been tried by a jury of his country, and found guilty of the murder of Captain Thornby, I now move that the sentence of the Court be pronounced upon that verdict. [Illustration: _Gibbs and Wansley burying the Money._] _By the Court_. Thomas J. Wansley, you have heard what has been said by the District Attorney--by the Grand Jury of the South District of New York, you have been arraigned for the wilful murder of Captain Thornby, of the brig Vineyard; you have been put upon your trial, and after a patient and impartial hearing, you have been found Guilty. The public prosecutor now moves for judgment on that verdict; have you any thing to say, why the sentence of the law should not be passed upon you? _Thomas J. Wansley_. I will say a few words, but it is perhaps of no use. I have often understood that there is a great deal of difference in respect of color, and I have seen it in this Court. Dawes and Brownrigg were as guilty as I am, and these witnesses have tried to fasten upon me greater guilt than is just, for their life has been given to them. You have taken the blacks from their own country, to bring them here to treat them ill. I have seen this. The witnesses, the jury, and the prosecuting Attorney consider me more guilty than Dawes, to condemn me--for otherwise the law must have punished him; he should have had the same verdict, for he was a perpetrator in the conspiracy. Notwithstanding my participating, they have sworn falsely for the purpose of taking my life; they would not even inform the Court, how I gave information of money being on board; they had the biggest part of the money, and have sworn falsely. I have said enough. I will say no more. _By the Court_. The Court will wait patiently and hear all you have to say; if you have any thing further to add, proceed.
