How little we know the way which lies before us. We long for sunlight, and perchance have only storms. We love to be as children who must be carried over the swamps and rough places, not knowing that strength of manhood and womanhood comes generally through struggling. The "happy years" at Monticello were already numbered. Another little girl had come to gladden the heart of the man who so loved children, and had quickly taken her departure. And now Martha Jefferson, at thirty-four, the sweet, gentle woman who had lived with him only ten short years, was also going away. She talked with him calmly about the journey; she said she could not die content if she thought their children would have a stepmother. The young governor, without a moment's thought as to his future happiness, taking her hand, solemnly promised that he would never marry again, and he kept his word. It is not known that any person ever entered the place left vacant in his heart by Martha Jefferson's death. For four months he had watched by her bedside, or had his books so near her that he could work without being separated from her. When she died he fainted, and remained so long insensible that the attendants thought he could never be restored to consciousness. For three weeks he kept his room, ministered to by his little daughter Martha, who wound her arms about his neck, with that inexpressible consolation that only a pure, sweet child-nature can give. She said years later, "I was never a moment from his side. He walked almost incessantly, night and day, only lying down occasionally, when nature was completely exhausted.... When, at last, he left his room, he rode out, and from that time he was on horseback rambling about the mountain, in the least frequented roads, and just as often through the woods. In those melancholy rambles I was his constant companion, a solitary witness to many a burst of grief." He longed now for a change of scene; Monticello was no more a place of peace and rest. Being elected to Congress, he took his seat in November, 1783. To him we owe, after much heated discussion, the adoption of the present system of dollars and cents, instead of pounds and shillings. In May, 1784, he was appointed minister to France, to join Dr. Franklin and John Adams in negotiating commercial treaties. He sailed in July, taking with him his eldest child, Martha, leaving Mary and an infant daughter with an aunt.
