Nay， the very colours of caterpillars are， as one has observed， very elegant and beautiful I shall， for a taste of the rest， describe one of them； which I will， some time the next month， shew you feeding on a willow- tree； and you shall find him punctually to answer this very description： his lips and mouth somewhat yellow； his eyes black as jet； his forehead purple； his feet and hinder parts green； his tail two-forked and black； the whole body stained with a kind of red spots， which run along the neck and shoulder-blade， not unlike the form of St.Andrew's cross， or the letter X， made thus crosswise， and a white line drawn down his back to his tail； all which add much beauty to his whole body.And it is to me observable， that at a fixed age this caterpillar gives over to eat， and towards winter comes to be covered over with a strange shell or crust， called an aurelia； and solives a kind of dead life， without eating all the winter.And as others of several kinds turn to be several kinds of flies and vermin， the Spring following； so this caterpillar then turns to be a painted butterfly.
Come， come， my scholar， you see the river stops our morning walk： and I will also here stop my discourse： only as we sit down under this honeysuckle hedge， whilst I look a line to fit the rod that our brother Peter hath lent you， I shall， for a little confirmation of what I have said， repeat the observation of Du Bartas：
God， not contented to each kind to give And to infuse the virtue generative， Made， by his wisdom， many creatures breed Of lifeless bodies.without Venus' deed.
So， the cold humour breeds the Salamander， Who， in effect， like to her birth's commander， With child with hundred winters， with her touch Quencheth the fire， tho'glowing ne'er so much.
So of the fire， in burning furnace， springs The fly Pyrausta with the flaming wings： Without the fire， it dies： within it joys， Living in that which each shine else destroys.
So， slow Bo 魌 es underneath him sees In th' icy isles those goslingshatch'd of trees； Whose fruitful leaves， falling into the water， Are turn'd， they say， to living fowls soon after.
So， rotten sides of broken ships do change To barnacles.O transformation strange！ 'Twas first a green tree； then， a gallant hull； Lately a mushroom； now， a flying gull.
Venator.O my good master， this morning-walk has been spent to my great pleasure and wonder： but， I pray， when shall I have your direction how to make artificial flies， like to those that the Trout loves best； and， also， how to use them ？
Piscator.My honest scholar， it is now past five of the clock： we will fish till nine； and then go to breakfast.Go you to yonder sycamore-tree， and hide your bottle of drink under the hollow root of it； for about that time， and in that place， we will make a brave breakfast with a piece of powdered beef， and a radish or two， that I have in my fish bag： we shall， I warrant you， make a good， honest， wholesome hungry breakfast.And I will then give you direction for the ****** and using of your flies： and inthe meantime， there is your rod and line； and my advice is， that you fish as you see me do， and let's try which can catch the first fish.
Venator.I thank you， master.I will observe and practice your direction as far as I am able.
Piscator.Look you， scholar； you see I have hold of a good fish： I now see it is a Trout.I pray， put that net under him； and touch not my line， for if you do， then we break all.Well done， scholar： I thank you.
Now for another.Trust me， I have another bite.Come， scholar， come lay down your rod， and help me to land this as you did the other.So now we shall be sure to have a good dish of fish for supper.
Venator.I am glad of that： but I have no fortune： sure， master， yours is a better rod and better tackling.
Piscator.Nay， then， take mine； and I will fish with yours.Look you， scholar， I have another.Come， do as you did before.And now I have a bite at another.Oh me！ he has broke all： there's half a line and a good hook lost.
Venator.Ay， and a good Trout too.
Piscator.Nay， the Trout is not lost； for pray take notice， no man can lose what he never had.
Venator.Master， I can neither catch with the first nor second angle： I have no fortune.
Piscator.Look you， scholar， I have yet another.And now， having caught three brace of Trouts， I will tell you a short tale as we walk towards our breakfast.A scholar， a preacher I should say， that was to preach to procure the approbation of a parish that he might be their lecturer， had got from his fellow-pupil the copy of a sermon that was first preached with great commendation by him that composed it： and though the borrower of it preached it， word for word， as it was at first， yet it was utterly disliked as it was preached by the second to his congregation， which the sermon- borrower complained of to the lender of it： and was thus answered： " I lent you， indeed， my fiddle， but not my fiddle-stick； for you are to know， that every one cannot make musick with my words， which are fitted for my own mouth".And so， my scholar， you are to know， that as the ill pronunciation or ill accenting of words in a sermon spoils it， so the illcarriage of your line， or not fishing even to a foot in a right place， makes you lose your labour： and you are to know， that though you have my fiddle， that is， my very rod and tacklings with which you see I catch fish， yet you have not my fiddle-stick， that is， you yet have not skill to know how to carry your hand and line， nor how to guide it to a right place： and this must be taught you； for you are to remember， I told you Angling is an art， either by practice or a long observation， or both.But take this for a rule， When you fish for a Trout with a worm， let your line have so much， and not more lead than will fit the stream in which you fish； that is to say， more in a great troublesome stream than in a smaller that is quieter； as near as may be， so much as will sink the bait to the bottom， and keep it still in motion， and not more.
