At this time he wrote several essays, which are esteemed among the best of his writings. He was awaiting permission from Congress to return to America. His son, the governor, who was receiving a pension of eight hundred pounds from the British Government, came over from England to his illustrious father, soliciting reconciliation. This was after the separation of many years. Franklin responded kindly, though he said that nothing had ever wounded him so keenly as to find himself deserted in his old age, by his only son; and to see him taking up arms against a cause, upon which he had staked life, fortune and honor. A year passed before Franklin was recalled. He was then so feeble that he could not walk, and could only ride in a litter. Mr. Jefferson succeeded him. Upon his arrival in Paris, the Count de Vergennes said, "You replace Dr. Franklin, I understand." "No!" Mr. Jefferson replied, "I _succeed_ him. No man can _replace_ him." Franklin's infirmities were such that he could not call upon the king or the minister for an audience of leave. He, however, wrote to Count de Vergennes a very grateful and affectionate letter, in which he said, "May I beg the favor of you, sir, to express respectfully for me, to his majesty, the deep sense I have of all the inestimable benefits his goodness has conferred on my country; a sentiment that it will be the business of the little remainder of the life now left me, to impress equally on the minds of all my countrymen. My sincere prayers are that God may shower down his blessings on the king, the queen, their children and all the royal family, to the latest generations." The reply was equally cordial and affectionate. As a parting gift the king sent Franklin his portrait, decorated with four hundred and eight diamonds. Its estimated value was ten thousand dollars. On the 12th of July, 1785, Franklin, accompanied by many admiring friends in carriages, commenced his slow journey in a litter, from Passy to Havre. It was four o'clock in the afternoon. The litter was borne by two mules. The first night they stopped at St. Germain. Thence the journey was continued at the rate of about eighteen miles a day. The motion of the litter did not seriously incommode him. The cardinal of Rochefoucald, archbishop of Rouen, insisted upon his accepting the hospitality of his mansion at Gaillon. It was a superb chateau, commanding a magnificent prospect, with galleries crowded with paintings and the most valuable works of art. "The cardinal," writes Franklin, "is much respected, and beloved by the people of this country; bearing in all respects, a most excellent character."
