Just a few of the words of presidential wisdom found in Dear Young Friend:I rejoice that you have learnt to write,for as this is done with a goosequill, you know the value of a goose. Thomas Jefferson, to his granddaughter, Cornelia RandolphAs to the whiskers, having never worn any, do you not think people would call it a bit of silly affection if were to begin now? Abraham Lincoln to Grace BedellIf we are successful [in the election], it will not be handsome behavior for any of my family to exhibit exultation or talk boastingly, or be in vain about it. Rutherford B. Hayes, to his son RuddyThe other sixty cents are for my other six grandchildren. They are not born yet. Theodore Roosevelt, to Marjorie Sterrett, who was collecting dimes to fund a battleshipThe John Birchers are just Ku Klux without the nightshirts. Harry Truman to David S. McCrackenIf you really believe, you will see them. My [Irish] little people are very small, wear tall black stovepipe hats, green coats and pants, and have long, white beards. John Kennedy to Mark Aaron PerduePresidents since Washington have written to children. Chief executives prior to the overwhelmingly busy present even went through the White House mail themselves, choosing what to answera task in the e-mail age now impossible.

The letters range in subject form the monumental to the immaterialalthough almost nothing is insignificant to a child.
