At the age of twenty-six (May 11, 1769), he took his seat in the House of Burgesses, of which Washington was a member. On the threshold of his public career, he made the resolution which was not once violated during his life, "never to engage, while in public office, in any kind of enterprise for the improvement of my fortune, nor to wear any other character than that of a farmer." Thus, during his career of nearly half a century, he was impartial in his consideration of questions of public interest.

His first important speech was in favor of the repeal of the law that compelled a master when he freed his slaves to send them out of the colony. The measure was overwhelmingly defeated, and its mover denounced as an enemy of his country.

It was about this time that Jefferson became interested in Mrs. Martha Wayles Skelton, a childless widow, beautiful and accomplished and a daughter of John Wayles, a prominent member of the Williamsburg bar. She was under twenty years of age, when she lost her first husband, rather tall, with luxuriant auburn hair and an exceedingly graceful manner.

She had many suitors, but showed no haste to lay aside her weeds. The aspirants indeed were so numerous that she might well hesitate whom to choose, and more than one was hopeful of winning the prize.

It so happened that one evening, two of the gentlemen called at the same time at her father's house. They were friends, and were about to pass from the hall into the drawing-room, when they paused at the sound of music. Some one was playing a violin with exquisite skill, accompanied by the harpsicord, and a lady and gentleman were singing.

There was no mistaking the violinist, for there was only one in the neighborhood capable of so artistic work, while Mrs. Skelton had no superior as a player upon the harpsicord, the fashionable instrument of those days. Besides, it was easy to identify the rich, musical voice of Jefferson and the sweet tones of the young widow.

The gentlemen looked significantly at each other. Their feelings were the same.

"We are wasting our time," said one; "we may as well go home."

They quietly donned their hats and departed, leaving the ground to him who had manifestly already pre-empted it.

On New Year's day, 1772, Jefferson and Mrs. Skelton were married and no union was more happy. His affection was tender and romantic and they were devoted lovers throughout her life. Her health and wishes were his first consideration, and he resolved to accept no post or honor that would involve their separation, while she proved one of the truest wives with which any man was ever blessed of heaven. The death of his father-in-law doubled Jefferson's estate, a year after his marriage. His life as a gentleman farmer was an ideal one, and it is said that as a result of experimentation, Jefferson domesticated nearly every tree and shrub, native and foreign, that was able to stand the Virginia winters.
