I don't think I've seen this system on here or Stenophile. Imperial Business Shorthand was published by the interestingly named Nuel Minstrel Clark in 1919. It appears on Butler's Chronological List and a copy can be found in the British Library.

This just a brief outline that I noted from a copy I viewed in the Bodleian Library some decades ago. The dots show where the characters start - they are not part of the system :-) (I don't know what happened to "ow").

Can anyone please tell me whether the double clove hitch is documented anywhere? I mean tying the standard hitch, but with an extra turn before passing the running end under both turns, much in the way a constrictor knot can be doubled. 

It seems more secure than the original clove hitch. I have used it to form a kind of Taut-line Hitch or jamming loop depending on its orientation. I discovered this knot for myself many years ago and it would be nice to know if any of these versions has an official name. 

There are undoubtedly better knots around for these purposes, but it does look quite neat!

​Method of Tying

1. Tie a loose overhand knot with the leading end on top and facing right - Step 1
2. Place the leading end over itself and the standing part - Step 2
3. Loop the leading end round twice - Step 3
4. Pass the leading end through the two loops - Step 4
5. Work the knot neatly together - Step 5

I look forward to any comments or information.
