How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
to run along, to follow
Sou is from Old Japanese 沿ふ (sopu), used in the Man'yōshū.
