After that, neither spoke during many minutes. The _Andromeda_ jogged along steadily south by west, and the threshing of the propeller beat time to the placid hum of her engines. The sturdy old ship could seemingly go on in that humdrum way forever, forging ahead through the living waters, marking her track with a golden furrow. "That is a very serious thing you have told me, Miss Yorke," muttered Hozier at last, not without a backward glance at the sailor in the wheel-house to assure himself that the man could not, by any chance, overhear their conversation. "But it is true--dreadfully true," said Iris, clasping her hands together and resting them on the high railing of the bridge. "It is all the more serious inasmuch as we are helpless," he went on. "Don't you see how impossible it is even to hint at it in any discussion with the man principally concerned? I want to say this, though--you are in no danger. There is no ship so safe as one that is picked out for wilful destruction. Men will not sacrifice their own lives even to make good an insurance policy, and I suppose that is what is intended. So you can sleep sound o' nights--at any rate until we near the coast of Brazil. I can only promise you if any watchfulness on my part can stop this piece of villainy---- Hello, there! What's up? Why is the ship falling away from her course?" The sudden change in his voice startled the girl so greatly that she uttered a slight shriek. It took her an appreciable time to understand that he was speaking to the man at the wheel. But the sailor knew what he meant. "Something's gone wrong with the wheel, sir," he bawled. "I wasn't certain at first, so I tried to put her over a bit to s'uth'ard. Then she jammed for sure." Hozier leaped to the telegraph and signaled "slow" to the engine-room. Already the golden pathway behind the _Andromeda_ had changed from a wavering yet generally straight line to a well-defined curve. There was a hiss and snort of escaping steam as the sailor inside the chart-house endeavored to force the machinery into action. "Steady there!" bellowed Hozier. "Wait until we have examined the gear-boxes. There may be a kink in a chain." A loud order brought the watch scurrying along the deck. Some of the men ran to examine the bearings of the huge fan-shaped casting that governed the movements of the rudder, while others began to tap the wooden shields which protected the steering rods and chains. In the midst of the hammering and excitement, Captain Coke swung himself up to the bridge. "Well, I'm blowed! _You_ here?" he said, looking at Iris. "Wot is it now?" he asked, turning sharply to Hozier. "Wheel stuck again?" "Yes, sir. Has it happened before?"
