Read it through once

On my re-entrance, I found Mr. Heathcliff below. He and Joseph were conversing about some farming business; he gave clear, minute directions concerning the matter discussed, but he spoke rapidly, and turned his head continually aside, and had the same excited expression, even more exaggerated. When Joseph quitted the room he took his seat in the place he generally chose, and I put a basin of coffee before him. He drew it nearer, and then rested his arms on the table, and looked at the opposite wall, as I supposed, surveying one particular portion, up and down, with glittering, restless eyes, and with such eager interest that he stopped breathing during half a minute together.
