That act of severe but just vengeance consummated, the negotiations for the ratification of the treaty were resumed. The Hall of Ceremonies was selected as the place in which the ratifying act should be performed, while, as some punishment for the hostile part he had played, the palace of Prince Tsai was appropriated as the temporary official residence of Lord Elgin and Baron Gros. The formal act of ratification was performed in this building on October 24. Lord Elgin proceeded in a chair of state, accompanied by his suite, and also by Sir Hope Grant with an escort of 100 officers and 500 troops, through the streets from the Anting Gate to the Hall of Ceremonies. Prince Kung, attended by a large body of civil and military mandarins, was there in readiness to produce the imperial edict authorizing him to attach the emperor's seal to the treaty, and to accept the responsibility for his country of conforming with its terms and carrying out its stipulations. Some further delay was caused by the necessity of waiting until the edict should be received from the emperor at Jehol authorizing the publication of the treaty, not the least important point in connection with its conclusion if the millions of China were to understand and perform what their rulers had promised for them. That closing act was successfully achieved, and more rapidly than had been expected. The Pekinese beheld English troops and officers in residence in their midst for the first time, and when the army was withdrawn and the plenipotentiary, Lord Elgin, transferred to his brother, Mr. Frederick Bruce, the charge of affairs in China as Resident Minister, the ice had been broken in the relations between the officials of the two countries, and the greatest, if not the last, barrier of Chinese exclusiveness had been removed. The last of the allied troops turned their backs upon Pekin on November 9, and the greater portion of the expedition departed for India and Europe just before the cold weather set in. A few days later the rivers were frozen and navigation had become impossible, which showed how narrow was the margin left for the completion of the operations of war.
