Federal P,,iaeip5es.-There is a pe- culiar unity of principle, or rather want of principle, in the conduct of the differ ent portions and individuals of the fede- ral party. Look over the history of that party from its first organization down to the present time, and you will find in their acts in all parts of the coun- try, prominent instances of the most shameless disregard of law aad right a seltishness and dishonesty, that is not even attempted to. be concealed. They seem to consider the rights of the people and the public treasury fair and ligiti- mate objects of violation and plunder. But a few days since, the federal Sena- tors in Congress, taking advantage of the temporary absence of the republican members, voted to give Gales and Sea ton, their party editors at Washington, $6i, ,00O, more for printing certain do- cuments, than Gen. Green offered to do them for, and Sf5,000 more than three other respectable printers offered to perform the same work for. Webster and Silsbee, and>liolmes aud Sprague, and all the other federal memoers, voted for this extraordinary resolution, to give a gratuity of S6l,O00 of the peoples money to Gales and Seaton; in effect to make present of this sum to them from the public funds. To descend from this grave assembly-from the highest Le- gislatiye bodyin the nation to the lowest, the Common Council of Boston, we find the same principle governingth federal members-but few years since our predecessor was deprived of contract for printing in violation of the plighted faith of the city-beeause he di9ered from them in politics-and they preferred pay ling one quarter more to q political friend, plundering the amount from the people, rather than an opponent should jhave his rights-and strange as it may seem the men who openly and shame Ilessly avowed their intention to violate a contract to gratify party hatred, hava been prompted, as. reccmpease for their destitution of moral principle.
