This has been a bright pleasant day, quite a rarity for a month past. There is no particular news in the papers. I have been down onto the Ave this evening. Called upon Mr Daws M.C. who is sick at his rooms co[rne]r of 8th & Ave, bought some maps and two Flags in view of the Celebration of the 22nd. I must make arrangements tomorrow to illuminate on Saturday night. We hear tonight with much sorrow that our little friend Willie Lincoln died at 5 p.m. He had been sick for near three weeks with Typhoid fever. “Bud” has been to see him or to enquire about him almost every day. He and his Mother were there yesterday about noon. Willie was then thought to be better. He was an amiable good hearted boy, was here with our boys almost every day or our boys were there. We all got much attached to him & “Tad” his Brother. He had more judgment and foresight than any boy of his age that I have ever known, poor Willie we all lament.
