browns, particularly when the water was a little stained after a small flood, afforded the angler good sport. In Herefordshire and Derbyshire, where trout and grayling are often found together, the same periods are generally best for angling; but in the Dove, Lathkill, and Wye, with the natural May-fly, many fish may be taken; and in old times, in peculiarly windy days, or high and troubled water, even the artificial May-fly, according to Cotton, was very killing. POIET.—I have heard various accounts of the excellent fishing in some of the great lakes in Ireland. Can you tell us any thing on the subject, and if the same flies may be used in that island? HAL.—I have been several times in Ireland, but never at this season, which is considered as best for lake-fishing. I have heard that in some of the lakes in Westmeath, very large trout, and great quantities may be taken in the beginning of June, with the very flies we have been using this day. Wind is necessary; and a good angler sometimes takes in a day, or rather formerly took, from ten to twelve fish, which weighed from 3 to 10lbs., and which occasionally were even larger. In the summer after June, and in the autumn, the only seasons when I have fished in Ireland, I have seldom taken any large trout; but in the river Boyle, late in October, after a flood, I once had some sport with these fish, that were running up the river from Lock Key to spawn. I caught one day two above 3lbs. that took a large reddish-brown fly of the same kind as a salmon fly; and I saw some taken that weighed 5lbs., and heard of one that equalled 9lbs. These fish were in good season, even at this late period, and had no spots, but were coloured red and brown—mottled like tortoise-shell, only with smaller bars. I have in July, likewise, fished in Loch Con, near Ballina, and Loch Melvin, near Ballyshannon. In Loch Con, the party caught many small good trout, that cut red; and in the other I caught a very few trout only, but as many of them were gillaroo or gizzard trout as common trout. POIET.—This must have been an interesting kind of fishing. In what does the gillaroo differ from the trout? HAL.—In appearance very little, except that they have more red spots, and a yellow or golden-coloured belly and fins, and are generally a broader and thicker fish; but internally they have a different organization, possessing a large thick muscular stomach, which has been improperly compared to a fowl’s, and which generally contains a quantity of small shell-fish of three or four kinds: and though in those I caught the stomachs were full of these shell-fish, yet they rose greedily at the fly. POIET.—Are they not common trout which have gained the habit of feeding on shell-fish?
