In most years these seasonal freshets have caused the river to cut through the bar across its mouth, occasionally in the past rather violently, and with loss of life (MacGinitie, 1935), providing for a time an outlet to the sea. In recent years it has been the practice to excavate a channel through the barrier of sand in order to release the swollen river before flooding of farmlands oc- 1 Judging from the account given by Scott, Harrison and Macnae (1952), the Klein River Estuary in South Africa bears a close general resemblance to the Salinas Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
