The third germinal stage was based on the draught of the Committee of Detail and extended from the 6th of August to the 12th of September. The draught of the Committee constituted the divide in the march of the framers. Behind them was the plain of philosophical disquisition on which there had been many contests, but exclusively as to what might be and might not be. Before them were many hills of difficulty to be surmounted in the practical application of abstract propositions by incorporating them in provisions and conditions to be written into the Constitution. But the work of the Convention and the debates of the members were in connection with the draughted Constitution of the Committee of Detail, or in connection with amendments thereof or additions thereto. There were indeed new provisions framed sometimes by grand committees, sometimes by special committees, sometimes by the Convention itself--provisions concerning which the Convention had not at first sufficiently instructed the Committee of Detail--provisions which the Convention had not then considered and determined even in the form of abstract propositions. The most difficult of the compromises, that between the large and the small States in the choosing of the President, was effected; and the method first proposed by Wilson and rejected by the Convention, June 2nd, that the choice should be made through the agency of electoral colleges was reconsidered and adopted. The power to try officers impeached by the House of Representatives was taken from the Supreme Court and given to the Senate; the power to appoint ambassadors, and judges of the Supreme Court, was taken from the Senate and given to the President; the power to appoint the Treasurer of the United States was taken from the Legislative branch and given to the Executive; and the important treaty-making power which at first was lodged exclusively in the Senate was transferred to the Executive subject to the ratification of the Senate. But all that was considered and agreed upon was attached to the draught of the Committee of Detail. The fourth stage began on the 12th of September with the revised Constitution reported by the Committee appointed "to revise the style of and arrange the articles" which had been agreed upon, commonly termed the "Committee of Style," but which more correctly might have been termed the Committee of Revision. During that and the next three days the Constitution was modified by a number of amendments chiefly of the nature of corrections. The Committee of Style made no changes other than those of arrangement and language. The correction of the language of the Constitution was masterly and is ascribed by Madison to Gouverneur Morris. On Saturday the 15th of September the labors of the Convention ended. On Monday the 17th, the engrossed Constitution was signed.
