Now and then, too, we read of a drive or walk or tea-drinking "with my wife"; but that is all. As a rule, John felt no more need of mentioning her, than the air he breathed, or the food that nourished him. She was there, and that was enough. By and by, however, Abigail began to speak, or rather to write for herself, and from now on her letters must be our best guide. Be it remembered that, in 1767, by the so-called Townshend Acts, a tax had been levied on glass, lead, paper, painters' colors, and tea. Three years later all these taxes had been repealed, except that on tea, which was retained as the sign and token of Great Britain's right to tax her colonies when and how she pleased. This fact, borne in mind, explains the following letter, written by Mrs. Adams on December 5th, 1773, to her friend, Mercy Warren, wife of General James Warren of Plymouth and sister of James Otis: "Do not, my worthy friend, tax me with either breach of promise or neglect towards you; the only reason why I did not write to you immediately upon your leaving town was my being seized with a fever, which has confined me almost ever since. I have not for these many years known so severe a fit of sickness. I am now, through the favor of Heaven, so far returned as to be able to leave my chamber some part of the day. I will not make any other apology for my past neglect, being fully sensible that I alone have been the sufferer. My pen, which I once loved and delighted in, has for a long time been out of credit with me. Could I borrow the powers and faculties of my much valued friend, I should then hope to use it with advantage to myself and delight to others. Incorrect and unpolished as it is, I will not suffer a mistaken pride so far to lead me astray as to omit the present opportunity of improvement. And should I prove a tractable scholar, you will not find me tardy. "You, madam, are so sincere a lover of your country, and so hearty a mourner in all her misfortunes, that it will greatly aggravate your anxiety to hear how much she is now oppressed and insulted. To you, who have so thoroughly looked through the deeds of men, and developed the dark designs of a rapacious soul, no action however base or sordid, no measure, however cruel and villanous, will be matter of any surprise.
