Read it through once

Mr. Pocket took me into the house and showed me my room: which was a pleasant one, and so furnished as that I could use it with comfort for my own private sitting-room. He then knocked at the doors of two other similar rooms, and introduced me to their occupants, by name Drummle and Startop. Drummle, an old-looking young man of a heavy order of architecture, was whistling. Startop, younger in years and appearance, was reading and holding his head, as if he thought himself in danger of exploding it with too strong a charge of knowledge.
