The hostility of the President to all measures which the Republican party deemed necessary for the proper reconstruction of the Southern States, had made a deep impression upon certain members of his Cabinet, and before midsummer it was known that a crisis was impeding.

On the 11th of July Mr.William Dennison, the Postmaster-general, tendered his resignation, alleging as the chief cause the difference of opinion between himself and the President in regard to the proposed Fourteenth Amendment to the Constitution.

He had for some months felt that it would be impossible for him to co-operate with the President, and the relations between them were no longer cordial, if they were not indeed positively hostile.

Alexander W.Randall of Wisconsin, the first assistant Postmaster-general, was an outspoken supporter of the measures of the Administration, and was using every effort to prejudice Mr.Johnson's mind against Mr.Dennison, whom he was ambitious to succeed.

Mr.Dennison felt that he was seriously compromising his position at home by remaining in the Cabinet, though he had been urged to that course by some zealous opponents of the Administration, who desired, as long as possible, to restrain the President from using the patronage of the Government in aid of his policy.
