“We must not throw things on the floor.”

“We must keep things in their places.”

“We must not mark the desks.”

“Nor the wall.”

How is it with the steps, or piazzas, or the halls?

“We must take the same care of them as of the inside.”

What of the yard?

“We must not throw papers or anything else in it.”

“Nor trample down the grass.”

“Except on the playground.”
