In 1889 the Post was given an oak log from the actual Acton cabin where five members of the Jones family became the first settlers killed in the Dakota Indian War of 1862, previously called the Sioux Uprising. It was taken to a sawmill in Forest City and made into lumber from which an altar, in the center of the room, and a gavel, which were both used during the meetings, were made. The altar is 32 ½ inches square and 36 inches high. It has a cushioned top covered with heavy leather. In the northwest corner of the meeting room is a miniature model of the Jones cabin and it was also made from wood from that log.
