It was at the end of the second month when Aaron took another step in advance—a perilous step. Sometimes on evenings he still went on with his drawing for an hour or so; but during three or four evenings he never asked any one to look at what he was doing. On one Friday he sat over his work till late, without any reading or talking at all; so late that at last Mrs. Bell said, "If you're going to sit much longer, Mr. Dunn, I'll get you to put out the candles."
