HAL.—Now for its anatomy. Its stomach is very thick, not unlike that of a char or gillaroo trout, and contains flies, gravel, and larvæ, with their cases. The liver and bowels do not differ much from those of a trout; and the ovaria or roe, with eggs as large as mustard seed, are on each side the air bladder. Though a thicker fish, the grayling does not weigh much more than the trout in proportion to his length: the greater breadth of back is compensated by the more rapid tapering of tail, and a trout in very high season will sometimes equal in weight a grayling of the same length. The ova in this fish, and in the species generally, are very small at this time of the year; but in the beginning of April, the season of their spawning, they become nearly as large as the ova of the trout—of the size of pepper-corns. But I see, Poietes, your rod is in order, and there are many fish rising in this deep pool, some of which are large grayling. The blue dun is on in quantity, and we have both cloud and wind, which half an hour ago we had no right to expect. Let me advise you to use three flies of different shades of the dun: the stretcher, a pale blue with yellow body; the first dropper, a winged fly with dun body; and the third, a similar fly with dark body. There, you see; he rose and refused your stretcher—and again he has a second time refused it. I think the colour of the dubbing is too bright: try a winged fly for the stretcher with a greenish body. Good—he has taken it, and ought to be a large fish. Now we have him: he is at least sixteen inches long, and in good season. Ornither, I advise you to use the same kind of fly, and to put up your tackle precisely in the same way as Poietes has done. POIET.—How well they rise! At that moment I had two on my line: one of them is gone, but I hope I shall land the other. HAL.—Fish with activity while the cloud lasts. I fear the sun is coming out, when it will be more difficult to take fish. I shall try the next pool, and I advise you to follow me and fish by turns,—passing each other, and taking different pools below, and so wend your way downwards, fishing wherever you see fish sporting. There is no better part of the river than that pool below you, and you cannot take a wrong direction. Immediately beyond Burrington Bridge you will find two excellent pools, and I advise you to go no farther down to-day. If you take a fish approaching 2lbs., keep him alive in the fish barrel for crimping; the smaller fish you can kill, and carry with some rushes in your basket; we shall at least be able to send a dish of grayling to the patron of our sport at Downton. NOON. HAL.—Well, gentlemen, I hope you have been successful.
