"You wouldn’t have much chance if you drifted out here without oars," ’Possum remarked.  "The current joins the one that sweeps down the lakes from ever so far up, an’ don’t they just race out to sea!  There was a party of girls in a boat—visitors—got into that current last year, an’ went bobbin’ along towards the Entrance.  They’d been told it was risky, so they lost their heads an’ dropped an oar, an’ then, of course, they had no chance at all."
