We were fairly after her now. The furnaces roared, and the powerful engines whizzed and clanked, like a great metallic heart. Her sharp, steep prow cut through the river-water and sent two rolling waves to right and to left of us. With every throb of the engines we sprang and quivered like a living thing.
