Flaked stone scrapers or scaling knives. Locality: North side Columbia R., Wash. opposite Umatilla, OR. Remarks: traded to CMNH.* According the Accession Record eighteen (18) scrapers were accessioned. Only fifteen (15) have been located. Perhaps it is the three missing ones that were traded to CMNH. Of the fifteen (15) chipped stone tools (scrapers) found in Burke collections, eleven of these were numbered 9071/1-8, 9071/10, 9071/11, and 9071/13. The numbers have worn off of four; we have assigned these four tools 9071/9, 9071/12, 9071/14, and 9071/15. We have assigned the three missing ones the numbers 9071/16, 9071/17, and 9071/18, although if they are found in our collections they may only have the number 9071 on them (these newly assigned numbers should be written on the artifacts if they are found). *Information is from the original accession ledger.
