Mar. 7,
Mangarita is a station on the electric
railway (Son. Pac.) which runs from San Jose
to San Rafael and lies on the west side
of Richardson Bay. Widow Reed Cr. empties
into the marshes on which it lies. Here
salt marsh, Mangarita, Richardson Bay,
Marin Co., Calif. I set out 14 mouse
traps in low Salicornia and rushes; traps
set about 8 ft. apart and about 25 ft. from
automobile trestle over the marshes. At the
next morning I found:
1 Microtus, 2 Reethrodontomys and
2 Peromyscus. The second locality
trapped (salt marsh, 2 mi. ESE Costa
Madera) was on the marshes bordering S.F.
Bay proper and at the south end of
the region about the mouth of Costa
Madera Cr. The locality is adjacent to
the high, non-marsh land at the north
end of Tiburon Peninsula. Here where
I trapped the grassy hillsides bound the
salt marshes - separated only by the
roadway. I put out 31 traps in
sparse Salicornia and in rushes and
some wild oat (little, along the road)
Found Sun. AM: 1 Peromyscus, 1 Microtus,
and 6 Reithrodontomys. Microtus runs
