Sun shining hazily this forenoon. Left on 10:02 train for Las Flores, fare 50¢. At Las Flores, we started up the track, then crossed on a wagon road to the beach, then north up beach. Shells not abundant except Donax laevigata, which thickly strewed the beach. Good walking for first half, after which the beach became steep and of soft sand, the hard beaten sand being covered by the surf, but with a good cow trail for the last two miles at the foot of the cliff. Cliff nearly vertical, with hard sandstone unconformably overlaid by coarse conglomerate about 100 feet thick, with some deep gulches dissecting it. The last two miles Donax disappeared but Chione were fairly common. Found two colonies of rock boring pelecypoda. Reached San Onofre at 3:16 p.m., having left Las Flores Station at 10:30 a.m. and stopped about 45 minutes for lunch. Caught the 4:28 train from San Onofre to Oceanside, $1.10. Got a box to finish packing our specimens 5¢. We are also expressing some clothes, frying
