>brought up thro' another string!

you know, I was going to point out that (over here, at least) these are known as 'threads'; but it occurs to me that 'strings' might indeed be more apposite to our little corner of the universe -- bear with me here....

thread - something continuous or drawn out, as a) a train of thought b) a continuing element

but, in particle physics,
string - a hypothetical one-dimensional object that is infinitely thin

anyway, that's my theory.
