Maybe a place where it gets a little more light? I'm not an expert on that plant, but do know that gererally plants that are exposed to higher light levels tend to be a little bushier.

Or, try "Basketing". Its a propgation method that works for vines like that in containers. Try a google search for the how to.

Pothos?
It's a vine; I'd expect it to grow long.

I recently aquired a Pathos vine clipping, and I am having trouble getting it to grow roots. I had it in a glass of water for about a week, but no roots. So then I put it in some moist soil and the bottom leaf died. I would prefer not to use hormone to get it to root. Is there any other way? Any suggestions?

A glass of water should work fine. You may have to give it more than just a week for it to start rooting. Try stripping some of the bottom leaves to encourage root growth.
