Mason felt that he was stultifying his country in condemning slavery.

Hence in roundabout language, "with such form of allusion to the _concession_ we held in reserve, as would make him necessarily comprehend it[1266]," and turning again and again to a supposed "latent, undisclosed obstacle[1267]" to British recognition, Mason yet made clear the object of his visit.

The word slavery was not mentioned by him, but Palmerston promptly denied that slavery in the South had ever been, or was now, a barrier to recognition; British objections to recognition were those which had long since been stated, and there was nothing "underlying" them.

On March 26, Mason called on the Earl of Donoughmore, a Tory friend of the South with whom he had long been in close touch, and asked whether he thought Palmerston's Government could be induced by a Southern abolition of slavery to recognize the Confederacy.

The reply was "that the time had gone by now...." This time the words "slavery" and "abolition" were spoken boldly[1268], and Donoughmore was positive that if, in the midsummer of 1863, when Lee was invading Pennsylvania, the South had made its present overture, nothing could have prevented British recognition.
