In the midst of her public cares and anxieties, she did not neglect her sacred duties as a mother. The care of the education of her four children devolved entirely upon her, and "Johnny" was at an age to require much attention. This subject occupied much of her thoughts; and, indeed, the greatest value of her published correspondence consists in the hints which it gives us of the course of culture pursued in producing those glorious fruits of which other generations have had the enjoyment. She carefully guarded against the contagion of vice at that period when the mind and heart are most susceptible to impressions. "I have always thought it," she says to her husband, "of very great importance that children should, in the early part of life, be unaccustomed to such examples as would tend to corrupt the purity of their words and actions, that they may chill with horror at the sound of an oath, and blush with indignation at an obscene expression. These first principles, which grow with their growth and strengthen with their strength, neither time nor custom can totally eradicate." By precept, and much more by example, she sought to instil principles, and to form habits, which should lead to the practice of every virtue. Can we be surprised at the abhorrence which her "illustrious son of an illustrious mother" has ever exhibited to oppression, when we find her thus expressing her sentiments in behalf of the oppressed, at a time when the subject of which she speaks had not excited any attention either in Europe or America?--"I wish sincerely there was not a slave in the province; it always appeared to me a most iniquitous scheme to fight ourselves for what we are daily robbing and plundering from those who have as good a right to freedom as we have." During the recess of Congress, Mr. Adams was at home, but left it again for Philadelphia on the 14th April, 1775. Four days afterwards the expedition to Lexington and Concord took place. The news of this event reached Mr. A. at Hartford; he, did not, however, yield to his anxieties and return, but contented himself by sending home encouragement and advice. After saying that he never feels any personal fear, he adds, "I am often concerned for you and our dear babes, surrounded as you are by people who are too timorous, and too much susceptible of alarm. Many fears and imaginary evils will be suggested to you, but I hope you will not be impressed by them. In case of real danger, fly to the woods with my children."
