It would not come regularly, but once, twice, thrice, a pause, and then once, twice and another pause.
"Who's making a noise ?" Dead silence.

A very long pause, and then it would begin again.
"That noise must cease, I say.

Jeremy, what are you doing ?" He would lift to her then eyes full of meekness and love.
"Nothing, Miss Jones." Soon it would begin again.

Miss Jones would be silent this time, and then Mary would speak.
"Please, would you ask Jeremy not to rub his boots together?
I can't learn my verse--" "I didn't know I was," says Jeremy.
Then it would begin again.

Jeremy would say: "Please, may I take my boots off ?" "Take your boots off?
Why ?" "They will rub together, and I can't stop them, because I don't know when I do it, and it is hard for Mary--" "Of course not! I never heard of such a thing! Next time you do it you must stand on your chair." Soon Jeremy is standing on his chair.
