There. Now we have the larvae of the four great trout-fly families, Phryganeae, Ephemerae, Sialidae, Perlidae; so you have no excuse for telling–as not only Cockneys, but really good sportsmen who write on fishing, have done–such fibs as that the green drake comes out of a caddis-bait, or giving such vague generalities as, ‘this fly comes from a water-larva.’
These are, surely, in their imperfect and perfect states, food enough to fatten many a good trout: but they are not all. See these transparent brown snails, Limneae and Succinae, climbing about the posts; and these other pretty ones, coil laid within coil as flat as a shilling, Planorbis. Many a million of these do the trout pick off the weed day by day; and no food, not even the leech, which swarms here, is more fattening. The finest trout of the high Snowdon lakes feed almost entirely on leech and snail–baits they have none–and fatten till they cut as red as a salmon.
Look here too, once more. You see a grey moving cloud about that pebble bed, and underneath that bank. It is a countless swarm of ‘sug,’ or water-shrimp; a bad food, but devoured greedily by the great trout in certain overstocked preserves.
Add to these plenty of minnow, stone-loach, and miller’s thumbs, a second course of young crayfish, and for one gormandizing week of bliss, thousands of the great green-drake fly: and you have food enough for a stock of trout which surprise, by their size and number, an angler fresh from the mountain districts of the north and west. To such a fisherman, the tale of Mr. ** *, of Ramsbury, who is said to have killed in one day in his own streams on Kennet, seventy-six trout, all above a pound, sounds like a traveller’s imagination: yet the fact is, I believe, accurately true.
This, however, is an extraordinary case upon an extraordinary stream. In general, if a man shall bring home (beside small fish) a couple of brace of from one to three pounds apiece, he may consider himself as a happy man, and that the heavens have not shone, but frowned, upon him very propitiously.
And now comes another and an important question. For which of all these dainty eatables, if for any, do the trout take our flies? and from that arises another. Why are the flies with which we have been fishing this morning so large–of the size which is usually employed on a Scotch lake? You are a North-country fisher, and are wont, upon your clear streams, to fish with nothing but the smallest gnats. And yet our streams are as clear as yours: what can be clearer?
Whether fish really mistake our artificial flies for different species of natural ones, as Englishmen hold; or merely for something good to eat, the colour whereof strikes their fancy, as Scotchmen think–a theory which has been stated in detail, and with great semblance of truth, in Mr. Stewart’s admirable ‘Practical Angler,’– is a matter about which much good sense has been written on both sides.
Whosoever will, may find the great controversy fully discussed in the pages of Ephemera. Perhaps (as in most cases) the truth lies between the two extremes; at least, in a chalk-stream.
Ephemera’s list of flies may be very excellent, but it is about ten times as long as would be required for any of our southern streams. Six or seven sort of flies ought to suffice for any fisherman; if they will not kill, the thing which will kill is yet to seek.
To name them:-
1. The caperer.
2. The March-brown.
3. The governor.
4. The black alder.
And two or three large palmers, red, grizzled, and coch-a-bonddhu, each with a tuft of red floss silk at the tail. These are enough to show sport from March to October; and also like enough to certain natural flies to satisfy the somewhat dull memory of a trout.
