JOHN COULTAS , now one of the most solid and substantial farmers now living upon North Prairie, was the third son of RICHARD and SARAH COULTAS, and was born on the 20th day of October, 1815, in Yorkshire, England. He emigrated to the United States with his father and brothers, in August, 1830, landed at Quebec, and from there they went to Buffalo, New York, from there to Wellsville, on the Ohio river. There they rook a boat for Louisville, Kentucky, and from there to St. Louis, Missouri, and from there to Naples, Illinois, where they arrived in the summer of 1830, and settled on section 3, township 14, range 12, where they moved into a log cabin, built originally by a Mrs. KIRKPATRICK. They then opened up a farm of 240 acres. Mr. COULTAS's father died, and additional duties and responsibilities developed upon him. He continued to work upon the farm, and he was married to Miss MARY PICKERING, a native who came to this country with her stepfather, WILLIAM HAXBY, and they had born to them six children, two daughters and four sons, five of whom are now living and all comfortably settled around their parents. Mr. COULTAS had the misfortune to loose his wife. She died, and he was again married to Miss MARY DEAN, a native of Cheshire, England. They have had a family of nine children, four sons and five daughters, eight of whom are still living, and all at home. Mr. COULTAS has always preferred farming, which he has been very successful in. He is a man who never sought office, but upon the contrary has been tendered time and again, positions of honor and trust by his political friends, and no man in Scott county wields a greater influence, politically, than does Mr. C. He has been a staunch supporter of the democratic party for many years, and is to-day a very active worker in the party.

He was one of Mr. DOUGLAS' warmest supporters. His first acquaintance with Mr. DOUGLAS was when DOUGLAS was on the road to Winchester, Illinois. He met Mr. DOUGLAS in the public road, and a conversation arose as to the size of the village and distance. DOUGLAS carrying his few clothes which he possessed in a small cotton hankerchief under his arm. He was forcibly struck with the appearance of Mr. DOUGLAS, and ever from that time he entertained a warm friendship for him, and was supporter of the great measures presented by him up to the time of his death.

Mr. C. resides on the old farm where he has raised his large family, which have proved to be a comfort and blessing to him and his wife. He has a farm well stocked with the finest of horses, cattle, hogs, and sheep, and it contains several hundred acres of the richest and most productive land in Scott county. Mr. and Mrs. COULTAS both bid fair to live many years to enjoy the fruits of their labor.
