Notice the refutation in the following argument:--

In no respect is the difference of opinion as to the methods of fishing so p.r.o.nounced and disturbing among anglers as the diverse ones of fishing "up" and "down" stream.

"Fishing up stream" has many advocates who a.s.sert that as trout always lie with their heads up current, they are less likely to see the fisherman or the glint of his rod when the casts are made; that the discomfort and fatigue accompanying wading against strong rapids is amply repaid by the increased scores secured; that the flies deftly thrown a foot or two above the head of a feeding trout float more life-like down the current than those drawn against it by the line, when they are apt to exhibit a muscular power which in the live insect would be exaggerated and unnatural.

On the other hand, the "down stream" fisherman is equally a.s.sertive as to the value of his method. He feels the charm of gurgling waters around his limbs, a down current that aids rather than r.e.t.a.r.ds or fatigues him in each successive step of enjoyment in his pastime; as he casts his fifty or more feet of line adown the stream, he is a.s.sured that he is beyond the ken of the most keen-sighted and wary trout; that his artificial bugs, under the tension of the current seaming it from right to left, reaches every square inch of the "swim," as English rodsters term a likely water, and coming naturally down stream, just the direction from whence a hungry trout is awaiting it, are much more likely to be taken, than those thrown against the current, with, doubtless, a foot or more of the leader drooping and bagging before the nose of a trout, with a dead bug, soaked and bedraggled, following slowly behind.

By wading "down stream" its advocates do not mean splashing and lifting the feet above the surface, sending the water hither and yon on to the banks, into the pools, with the soil of silt or mud or fine gravel from the bottom, polluting the stream many yards ahead, and causing every fish to scurry to the shelter of a hole in the bank or under a shelving rock.

They intend that the rodster shall enter the water quietly, and, after a few preliminary casts to get the water gear in good working order to proceed down stream by sliding rather than lifting his feet from the bottom, noiselessly and cautiously approaching the most likely pools or eddies behind the roots in mid stream, or still stretches close to the banks, where the quiet reaches broaden down stream, where nine chances in ten, on a good trout water, one or more fish will be seen lazily rising and feeding.

Again, the down-stream angler contends that when a fish is fastened on a hook, taking the lure in a current, that he is more likely to be well hooked, hence more certain of capture when the line is tense, than when rising to a floating bug at the end of a looping line and leader.

Certainly it is very difficult when casting against the current to keep the line sufficiently taut to strike quickly and effectively a rising trout, which as a rule ejects the artificial lure the instant he feels the gritty impact of the steel.

In fishing down stream, the advocate of the principle that the greater the surface commotion made by the flies used, the surer the rise and catch, has an advantage over his brother who always fishes "fine" and with flies that do not make a ripple. Drawing the artificial bugs across and slightly up stream over the mirrored bosom of a pool is apt to leave a wake behind them which may not inaptly be compared with the one created by a small stern-wheel steamer; an unnatural condition of things, but of such is a trout's make-up.

SUMMARY

1. Argument is that form of discourse which attempts to prove the truth of a proposition.

2. Inductive reasoning is that process by which from many individual cases we establish the probable truth of a general proposition.

3. The establishing of a general truth by induction requires-- _a._ That there be a large number of facts, circ.u.mstances, or specific instances supporting it.

_b._ That these facts be true.

_c._ That they be pertinent.

_d._ That there be no facts proving the truth of the contrary proposition.

4. Deductive reasoning is that process which attempts to prove the truth of a specific proposition by showing that a general theory applies to it.

5. The establishing of the truth of a specific proposition by deductive reasoning requires-- _a._ A major premise that makes an affirmation about _all_ the members of a cla.s.s.

_b._ A minor premise that states that the individual under consideration belongs to the cla.s.s named.

_c._ A conclusion that states that the affirmation made about the cla.s.s applies to the individual. These three statements const.i.tute a syllogism.

6. An enthymeme is a syllogism with but one premise expressed.

7. Errors of deduction arise-- _a._ If terms are not used throughout with the same meaning.

_b._ If the major premise does not make a statement about every member of the cla.s.s denoted by the middle term.

_c._ If either premise is false.

8. Belief in a specific proposition may arise-- _a._ Because of the presentation of evidence which is true and pertinent.

_b._ Because of a belief in some general principle or theory which applies to it.

In arguing therefore we-- _a._ Present true and pertinent facts, or evidence; or _b._ Appeal directly to general theories, or by means of facts, maxims, allusions, inferences, or the quoting of authorities, seek to call up such theories.

9. Cla.s.ses of arguments:-- _a._ Arguments from cause.

_b._ Arguments from sign and attendant circ.u.mstances.

_c._ Arguments from example and a.n.a.logy.

10. Arrangement.

_a._ Arguments from cause should precede arguments from sign, and arguments from sign should precede arguments from example.

_b._ Inductive arguments usually precede deductive arguments.

_c._ Arguments should be arranged with reference to climax.

_d._ Arguments should be arranged, when possible, in a coherent order.

11. In making a brief the above principles of arrangement should be observed. Attention should be given to unity so that the trivial and false may be excluded.

12. Persuasion is argument that aims to establish the wisdom of a course of action.

13. Persuasion appeals largely to the feelings.

_a._ Those feelings of satisfaction resulting from approval, commendation, or praise, or the desire to avoid blame, disaster, or loss of self-esteem.

_b._ Those feelings resulting from the proper and legitimate use of one's powers.

_c._ Those feelings which arise from possession, either actual or antic.i.p.ated.

14. Persuasion is concerned with-- _a._ Questions of right.

_b._ Questions of expediency.

I. ELEMENTS OF FORM

+1. Importance of Form.+--The suggestions which have been made for the correction of the Themes have laid emphasis upon the thought. Though the thought side is the more important, yet careful attention must also be given to the form in which it is stated. If we wish to express our thoughts so that they will be understood by others, we shall be surer to succeed if we use the forms to which our hearers are accustomed. The great purpose of composition is the clear expression of thought, and this is aided by the use of the forms which are conventional and customary.
