These letters are old type letters so I could not read completely, but I translated it as follows.
Yuubin Houchi Shimbun No.491
Ohta Hachiemon, a Farmer in sough village, Bushu-Tachibana district, Kanagawa prefecture, answered to the military conscription to his son Fusajiro. He has so delighted and moved about the conscription that he cut his pinky finger and gave it to his son as a going-away gift at the moment of departure. He said his son that you must prepare to die for the good of the nation, and do not long for your home. Then Fusajiro also cut his pinky finger and gave it to his father, and said he will sure to comply his father's order, and will prepare for death.
(After this, I could not read well, but as an outline, it says Fusajiro has bravely left his home.)
