"Wal, Sir, it seems by the time Obed knowed them islanders they was all full o' fish blood from them deep water things. When they got old an' begun to shew it, they was kep' hid until they felt like takin' to the water an' quittin' the place. Some was more teched than others, an' some never did change quite enough to take to the water; but mosily they turned out jest the way them things said. Them as was born more like the things changed arly, but them as was nearly human sometimes stayed on the island till they was past seventy, though they'd usually go daown under for trial trips afore that. Folks as had took to the water gen'rally come back a good deal to visit, so's a man ud often be a'talkin' to his own five-times-great-grandfather who'd left the dry land a couple o' hundred years or so afore.
