>7. **Nothing to look at, delightful to hold.  
The key to my nature is written on gold.**

 - **Solution/Explanation:**  
 >! The solution to this is **The One Ring**.  The ring referred to in *The Hobbit* renders the wearer invisible ("nothing to look at").  Once someone possesses it, it is very hard for them to give it up ("delightful to hold").  The ring is golden, and contains an inscription describing its nature.

>8. **I might be applied to a tally of years,  
A steed or a horseman or, yes, even beers.  
I may well be named as the cause of ho-hos  
As he who examines the calendar knows.**

 - **Solution/Explanation:**  
 >! The solution to this is **Dark**.  The Dark *Ages* are a "tally of years". A "dark *steed*" a "dark *horseman*" and "dark *beer*" are common phrases. Dark *humour* might be the cause of "ho-hos" (laughs).  One who "examines the calendar" may be overly preoccupied with death, a common subject of dark humour.

>9. **I write my name to rule the song.  
Go back, give out. I say how long.  
I may be called, I may be cut.  
I may be done when bars are shut.**
