We have been here now three days and will leave tomorrow. It is very hot, myriads of fleas annoy us and pests of ants invaded our beds one night. North of the marsh that skirts the bay for some miles is a very rich agricultural region, teeming with grain.
Specimens collected: Pickeringia montana var. montana; Quercus wislizeni.
