Now circumstances had so much manners (contrary to their custom) that they contrived to keep themselves continually in my favour. Not only did I fetch up and pile a noble heap of oysters and mussels just at the lowest of the ebb, but after that, when the tide was flowing, and my work grew brisker--as it took me by the calves, and my feet were not cut by the mussels more than I could walk upon--suddenly I found a thing beating all experience both of the past and future. This was, that the heat of the weather, and the soft south wind prevailing, had filled the deep salt-water pools among the rocks of Pool Tavan, and as far as Ffynnon wen, with the finest prawns ever seen or dreamed of; and also had peopled the shallow pools higher up the beach with shoals of silver mullet-fry--small indeed, and as quick as lightning, but well worth a little trouble to catch, being as fine eating as any lady in the land could long for. And here for a moment I stood in some doubt, whether first to be down on the prawns or the mullet; but soon I remembered the tide would come first into the pools that held the prawns. Now it did not take me very long to fill a great Holland bag with these noble fellows, rustling their whiskers, and rasping their long saws at one another. Four gallons I found, and a little over, when I came to measure them; and sixteen shillings I made of them, besides a good many which Bunny ate raw. Neither was my luck over yet, for being now in great heart and good feather, what did I do but fall very briskly upon the grey mullet in the pools: and fast as they scoured away down the shallows, fluting the surface with lines of light, and huddling the ripples all up in a curve, as they swung themselves round on their tails with a sweep, when they could swim no further--nevertheless it was all in vain, for I blocked them in with a mole of kelp, weighted with heavy pebbles, and then baled them out at my pleasure. Now the afternoon was wearing away, and the flood making strongly up channel by the time I came back from Ffynnon wen--whither the mullet had led me--to my headquarters opposite Sker farmhouse, at the basin of Pool Tavan. This pool is made by a ring of rocks sloping inward from the sea, and is dry altogether for two hours' ebb and two hours' flow of a good spring-tide, except so much as a little land-spring, sliding down the slippery sea-weed, may have power to keep it moist. A wonderful place here is for wild-fowl, the very choicest of all I know, both when the sluice of the tide runs out and when it comes swelling back again; for as the water ebbs away with a sulky wash in the hollow places, and the sand runs down in little crannies, and the bladder-weeds hang trickling, and the limpets close their valves, and the beautiful jelly-flowers look no better than chilblains,--all this void and glistening basin is at once alive with birds.
