"As for you, Snail Looper," continued Coach Lighton, giving the center the name he had earned from his habit of prowling about nights and moving at slow speed, "you are doing fairly well, but be a little quicker. Try to forget that you're a relative of the _Helix Mollusca_. You backs, get into plays on the jump, and take advantage of the momentum. That's the way to smash through the line. Now then, we'll try signals again. Clinton, keep a cool head. Nothing is worse than getting your signals mixed, and you fellows, if you don't understand exactly what the play is, call for the signal to be repeated. That will save costly fumbles. Now line up again."
