His captive was, however, soon safe in the large basket, and he had hardly closed the lid and placed a boulder used as ballast upon it before a tug at his other line made the thole-pin rattle, and after a little hauling he dragged in a gloriously-coloured gurnard, whose outspread fins looked like the wings of some lovely butterfly.  Then he drew in, one after the other, a couple of wrasse, all grey and green and gold, with their protuberant mouths and curious teeth, after which there was a pause, and, drawing up one of his lines, Harry placed thereon a much larger hook, bound with wire right up the cord that held it.  Upon this he placed quite half a mackerel, secured it well to the hook with a piece of string, and then, throwing it over the side, he waited, after feeling the lead touch the rock below, and wondered whether he should capture what he believed to be lurking amongst the ledges of the piece of rock.
