JOSEPH BLANCHET. - The farm of twelve hundred and eighty acres of fenced and improved land, belonging to Mr. Blanchet, is a sight rare even for this region of big farms. Its proprietor has been so successful in multiplying his flocks and droves, that he has been obliged to remove a part of them to Idaho. He came to Vinson in 1880; and his acquisitions have thus been the work of but a few years. He was born in Canada in 1846, and was occupied, until his removal to this coast, in draying in the cities. He has three fine boys, Nicholas, John and Eugene. His wife, Hermine du Puis, whom he married at Vancouver, Washington, died in 1886. Joseph Blanchet is known throughout Eastern Oregon as a man of great practical intelligence, of rigid honesty, whose word is a good as his bond, and he is respected accordingly.
