sand rips are like this. The layers are at rest up right each in middle. Outside of Hialeas, Fulger, Notice and Sand- dollars me sees almost nothing otherwise on the beach. I saw only one piece of crab. It is the same living fauna - buried in the sand - that me sees here! The 60 feet depth line is here near 25 miles off shore and it is justifiable that the sand fauna goes out from shore several miles. The just amount of sand in northern Florida must come from the streams south of St. Augustine. All of these streams are loaded with fine sand derived from the Oreognic deposits and as much from some of the Tertiary knights. The southerly winds plus the return current flows south along the shore of Florida transport it farther and farther south. In the salt marshes I did not go, in one place I saw the mud crabs with (Cassia) smily trinitata. Where the saw grass arounds the crab is full of holes hollowed there of crabs.
