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, circumstances, 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 class.
  b. A minor premise that states that the individual under consideration
        belongs to the class named.
  c. A conclusion that states that the affirmation made about the class
        applies to the individual.  These three statements constitute a
        syllogism.
