Two letters to the boy himself are among Franklin's published writings. The first is couched in sweet, simple terms, suited to the age of his youthful correspondent, and the second is interesting only as evidencing how closely the grandfather scanned the drawings and handwriting of his grandson, and as emphasizing the importance that he always attached to arithmetic and accounts as elements of an useful education. Sally's reply to her father's rebuke, on account of the modish vanities, that she asked of him, was quite spirited. How could my dear papa [she said] give me so severe a reprimand for wishing a little finery. He would not, I am sure, if he knew how much I have felt it. Last winter (in consequence of the surrender of General Burgoyne) was a season of triumph to the Whigs, and they spent it gayly; you would not have had me, I am sure, stay away from the Embassadors' or Gerard's entertainments, nor when I was invited to spend a day with General Washington and his lady; and you would have been the last person, I am sure, to have wished to see me dressed with singularity: Though I never loved dress so much as to wish to be particularly fine, yet I never will go out when I cannot appear so as to do credit to my family and husband. Apparently, Sally was not always so unsuccessful as she was on this occasion in her efforts to secure something to wear, suitable to her situation as the daughter of a very distinguished citizen of Philadelphia in easy circumstances. Nothing, she once wrote to her father, was ever more admired than her new gown. It is obvious, however, that Franklin was resolved that his daughter at least should heed and profit by what Father Abraham had to say in his discourse about the effect of silks, satins, scarlet and velvets in putting out the kitchen fire. In his will, he bequeathed to her the picture of Louis XV., given to him by the King, which was set with four hundred and eight diamonds, "requesting, however, that she would not form any of those diamonds into ornaments either for herself or daughters, and thereby introduce or countenance the expensive, vain, and useless fashion of wearing jewels in this country." The outer circle of the diamonds was sold by Sally, and on the proceeds she and her husband made the tour of Europe.
