I m told it in essays from é.c. Powell 1919 (3 essays on flyfishing) book is not available anywhere.
Indeed, I got my copy from Walton Powell (authors' son) himself when the Powell company was still alive. His grand son Press Powell published the "Essays on fly fishing" in 1989, it gathers texts from 1910, 1919 and 1937, including the following document which I bought from an English book specialist many years ago.

Now I think it is time to press the Pause button Michael, since our discussion is going nowhere. I shall wait and see if your theory substanciate in the future.

Let's assume that the line attached to the rod is the ground, that the wave is the c that forms and the line above is the back of the wave, raising the line below, the wave should increase in height, because it has the opposite behavior ? or is it just my impression of ignorance on the subject?
Thanks for your patience.
I'm sorry Ivan. I think I'm losing the essence of your question in the translation to English. Can you ask again with different phrasing?

Cheers,

The rod launches the line, a wave is formed, the same runs on the line, because by varying the position in which the rod stops or the speed, the wave does not progress, because when it reaches the end of the line there is less space between the part below and the one above does not open upwards? thanks for your patience.

As James neatly pointed out in his FP “the Big Spring”
Hi Paul

A link please?

Is there a page where one can find archive FP's?

Cheers,
Dirk

Archived pages link can be found under the daily cast Mon-Sun on the FP, which leads to this page, Dirk: https://www.sexyloops.com/index.php/daily-cast-archive/ which can ultimately take you back to 2006.

The Search function is ok otherwise Googling a search with Sexyloops.com often finds pages as well.

Cheers, Paul

@merlin

Awesome and what does it say on this book? Can you tell me that pls? Or copy the relevant passages?
Why are u telling me to pause?
I think it's only getting interesting now....
Plus we are going somewhere... We discuss and we think. And I know exactly where I m going.

Now pls look into these booklets and show me the part where the loop is mentioned for the first time in terms of casting.... So it's there. And I hope it's not only saying : it's called a loop...

That would be hollow and dissapointing

Cheers and TL

Michael

The booklet ‘Essays on fly fishing’ contains a reprint of ‘The mechanics of fly casting’

The relevant text is in post #148, and Powell said “The tip bend produces what is generally termed a narrow loop or U in the line as it unfurls”.

The term loop was thus already popular by 1937. Is there a document written by another author allowing finding when that term was coined, nobody knows I think. It is just a popular term, existing since about a century, final point.

I really can’t understand why you are after a supposed to be written proof which may not exist; that will not change the accepted use of that term in the fly fishing world (improper for you, and maybe only you).

@merlin
Is that all it says? That's hard to believe.

How did the transfer from 1885 s technical tackle définition (where there is no word about casting) make it in the line picture till 1937?

If so it's just indeed a generalisation. A thoughtless one. Saying that when did science learn about wave physics? An interesting question in thus context I think.

I totally get that you don't like where I m drilling and looking behind the facts and sources.

So I m sure there is more (especially between the lines) and I also know that u will be well able to interpret this. And you will find. the written origin of the misconception of the loop in there with very high probability. And I consider it as your duty as a proper sportsman to do so. Or lay it open.

I disprove the loop anyway. With 3 casts in 3 three minutes. I have done this before and I m also not alone despite u think it is the case. And if I was the only 1 I d still do it.

And I have a source that is older than yours. It's only a matter of time. I d suggest u better get behind it and find it first.... Or somebody else will. I m very jealous of you owning this book.

It's about the big picture. And it will help future flyfishers and the future of flyfishing. It's a bit in a sore state right now.

Cheers and TL

Merlin, I m also very happy to discuss this further with you by private message, if u can handle it. Pls work with me.

I think I understand the question.

The line is falling while the wave rises through it so there is no opening up of the wave.
