"That has been arranged for," said the captain. "Directly the arc of fire on one pair of guns is exceeded, that turret remains locked till the other guns are trained backward sufficiently for that pair to be automatically linked up, so that damage to our own ship from that cause is impossible. Of course, if necessary, each turret can be worked independently, and in that case the captains of the guns would have the control of the firing arrangements." Further conversation was interrupted by the arrival of a signalman. "Wireless message just received, sir," he reported, handing a sealed envelope to the captain with a salute. Captain Brookes broke open the envelope, and read and reread its contents without moving a muscle; then he beckoned to those of the officers who happened to be on the quarter-deck. "Gentlemen," he exclaimed, "a wireless of extreme importance has just been handed to me. The captain of the _Afrika_ has reported an outrage by a ship flying the White Ensign, and representations have been made by the German Ambassador in London. The British Government has rightly repudiated the suggestion that the delinquent was a British man-of-war, and has asserted that, from the description given, it can only be the ex-Brazilian cruiser _Almirante Constant_. Consequently the British and German Governments have issued a joint note branding that vessel as a pirate, and have stated their intention of hounding her down at all costs, and invite the navies of all nations to join them in their task. So, gentlemen, the _Olive Branch_ is a modern buccaneer. Every port and harbour is closed against her. However, I'll stick to my purpose, but, rest assured, I will never fire a shot against a British ship--I'll trust to the _Olive Branch's_ speed to shake off pursuit. But"--here his face clouded ominously--"should a vessel of any other nationality attempt to interfere with us, I'll give her a fair warning. If she persist, by Jove, I'll blow her sky high!" [Illustration: chapter XI] CHAPTER XI WIPED OUT ALMOST without further incident the _Olive Branch_ arrived off the coast of Chili. Hostilities had broken out between that State and her old rival, Peru, but beyond a few encounters between outposts on the frontier, no serious fighting had yet taken place. Both republics were unwilling to undertake the risk of sending an army into hostile territory until the safety of their respective seaboards was assured, and every day news of a decisive engagement between the rival fleets was expected. Directly the _Olive Branch_ was in touch with Captain Brookes's agent at Antofagasta a wireless message was despatched in the form of an ultimatum to the Presidents of Chili and Peru, stating that unless the two fleets returned to their respective ports and peace were declared within three days, the _Olive Branch_ would be compelled to intervene.
