Answer:
My first is second in line; I send shivers up your spine; not quite shining bright I glitter in the light.
I'm tall when I'm young and short when I'm old. What am I?
I am what brings things together. Without me everything you see would be a total mass or debris everywhere. What am I?
I move without wings Between silken string I leave as you find My substance behind.
I am flora not fauna. I am foliage not trees. I am shrubbery not grass.
I fly to any foreign parts assisted by my spreading wings. My body holds an hundred hearts Nay I will tell you stranger things when I am not in haste I ride and then I mend my pace anon.
