When Marco came in, he found that his hour for arithmetic was so nearly expired, that he should not have time to finish another sum, if he should begin it; so he put his arithmetical apparatus away, and took out his writing-book.
Marco went through the whole forenoon pretty much in the same way.

He spent a large part of his time in looking out of the window and about the room.

He went out at the time for the recess, but he stayed out twenty minutes instead of ten.

He was astonished, when he came in, to see how rapidly the time had passed.

He then took down a volume of the Encyclopedia, and read until twelve o'clock, and then, leaving the volume of the Encyclopedia and his writing-book on his desk, he told Forester that the study hours were over, and went away.
The next morning, at nine, Forester asked him how he had got along the day before.
