FARMER FINDS GRAVES OF ANCIENT RACE IN OREGON
Albany, Oregon, March 22 - A burial ground of what is pronounced to be an ancient group of mound builders has been unearthed directly across the river from Albany by Clyde Peacock, a farmer. Mr. Peacock made the discovery while plowing in a field which has been under cultivation for many years. The plowshare was caught by a rock which investigation showed was a fine specimen of a mortar.
Digging further, Peaccok unearthed skulls, knives, skeletons and more mortars and pestles. An area of about 50 feet long and about 20 feet wide has been excavated to a depth of one half to 2 1/2 feet.
J.C. Crawford, local authority on prehistoric specimens, held the theory that the skeletons were buried shortly after 500 B.C.,Mr. Crawford says that the pestles and mortars were buried with their dead, by mound builders. Upon examining some of the best specimens of bones, Mr. Crawford declared that the race had been one of great size and strength.
