STONE, Delos S. (d. 1896)
On Saturday, June 20th, 1896, the community was shocked and startled by the sudden death of Delos S. Stone, of this city. Mr. Stone had been suffering for a long time, but has kept on his feet and been able to attend to his personal affairs, and could have been seen upon our streets almost any day up to the time of his death. He was a victim of that dreaded disease known as paralysis, that comes with the rush and weep of a cyclone, and invariably leaves a prostrated and helpless form or corpse in its wake.
Mr. Stone was born in Jamestown, in the now noted and historical county of Chautauqua, in the state of New York, on Aug. 12th, 1833. He afterwards moved to Ohio, and in the early days of the rebellion enlisted as a private soldier for three years in company B, 12th regiment, Ohio Infantry. He was honorably discharged at Nashville, Tenn., on May 1st, 1863. At the age of 17 he became a member of the church, and since that time has been a zealous and consistent Christian. The deceased came to Blaine in 1889. After viewing the country around about, he decided to locate on a tract of government land near Langley, B. C. He and his family settled there and remained until about three years ago, when they returned to Blaine. Mr. Stone came to Blaine from Marshalltown, Iowa. Prior to his residence in Iowa, he had lived in Jackson county, Kan. Part of his allotted years were spent as a school teacher. He was a regularly ordained United Brethren minister, and spent several years in church work.
His father died when he was eleven years of age. A brother, who has not been heard from for four years is the only blood relative who survives. To Mrs. Alice Stone, the widow of the deceased, the sympathy of the whole community is extended. Mr. Stone was an upright, conscientious, pure minded, whole souled citizen, and we venture to say that he had not an enemy in the world. Funeral exercises were conducted at the Methodist Episcopal church on Sunday last, Rev. J. W. White preaching the funeral sermon from II. Timothy iv., 6-8. The deceased being a member of Reynolds Post G. A. R. of Blaine during his lifetime, the exercises at the Blaine cemetery were conducted under the auspices of the post. A large concourse of our people attended the exercises at the church and at the cemetery.
