Stanley has trapped for the U.S. Reclamation Service for 22 years. Traps gophers and muskrats from the drainage canals. Caught 4,000 muskrats last year. These are a great problem here, but not at Bark in the area Perry worked. Stanley told us that in a high school gopher-trapping contest in this area last year, 37,000 gophers were caught. Contest winner caught 800+. Spent rest of day looking for a camp site and settled at a point: 4 mi. SE Goldsen, 120'; Yuma to., Ariz.
