THE great ship trembled to the recoil of the cannon; the rattle of musketry.
The roar of the guns aboard her sister ships and the roar of her own were deafening. Below decks the air was acrid with the fumes of burnt powder. Tanar of Pellucidar, chained below with other prisoners, heard these sounds and smelled the smoke. He heard the rattle of the anchor chain; he felt the straining of the mast to which his shackles were bent and the altered motion of the hull told him that the ship was under way.
