In 1778, the fortitude of Mrs. Adams received a new trial. Her husband was appointed one of the commissioners at the court of France. The sea was covered with the enemy's ships; and, should he escape these and all the natural dangers of the seas, and arrive at the place of his destination in safety, rumor said that he would there be exposed to one of a more terrific character, "to the dark assassin, to the secret murderer, and the bloody emissary of as cruel a tyrant as God, in his righteous judgments, ever suffered to disgrace the throne of Britain. I have," continues Mrs. Adams, writing soon after her husband's departure, "travelled with you across the Atlantic, and could have landed you safe, with humble confidence, at your desired haven, and then have set myself down to enjoy a negative kind of happiness, in the painful part which it has pleased Heaven to allot me; but the intelligence with regard to that great philosopher, able statesman, and unshaken friend of his country,"--alluding to a report of Dr. Franklin's assassination in Paris,--"has planted a dagger in my breast, and I feel with a double edge the weapon that pierced his bosom. * * * To my dear son remember me in the most affectionate terms. Enjoin it upon him never to disgrace his mother, and to behave worthily of his father. I console myself with the hopes of his reaping advantages under the careful eye of a tender parent, which it was not in my power to bestow." Mr. Adams was accompanied by his eldest son, John Quincy Adams, and, after incurring various hazards from lightning, storm, and the enemy, arrived in France. The maternal solicitude of Mrs. Adams relieved itself in part by writing letters to her son filled with the warmest affection and the most wise counsel. She urges it upon him "to adhere to those religious sentiments and principles which were early instilled into your mind, and remember that you are accountable to your Maker for all your words and actions. Great learning and superior abilities, should you ever possess them, will be of little value and small estimation, unless virtue, honor, truth, and integrity, are added to them. Dear as you are to me, I would much rather you should have found a grave in the ocean you have crossed, than see you an immoral, profligate, or graceless child."
