Also a trail like this seen leading into driftwood drift beside a pool about high tide mark. Big enough trail for Rottis Many of the smaller shore birds seen but no predators noticed. Also no birds that would seem to prey on mice more except possibly guils have been seen here to date. APRIL Bayshore Highway & Buchanan Street, Albany, Alameda Co., Calif. Set out 50 Mts.

May have been old microtus or old Thomomys feeding holes. Did not appear to be in use now tho. Some
