As soon as the other ship perceived this change in direction, she veered off her course closer to the wind, and almost immediately the boys could see the white flutter of some extra canvas being spread at her bows. As this new piece filled out, it proved to be a great balloon jib, which increased her sail area by nearly half. Her head came off the wind again and she went bowing along over the swells to the southward faster than one would have imagined possible. Bonnet had figured on crossing her at close range, but as she swept onward he realized that he would go by too far astern to hail her if he kept his present direction. Herriot himself took the tiller. As quickly as he could, without loss of headway, he eased the _Royal James_ over till she was running nearly parallel with the fleeing ship. His orders came quick and fast, while the men trimmed the main and fore sheets to the last hair's breadth of perfection. It was to be a race, and a hard one.
For nearly half an hour the sloops ran along almost neck and neck and perhaps half a mile apart. The pirates dared not risk pointing closer to the wind in order to get into cannon range. They would have lost so much speed that it would have developed into a stern chase--useless since they possessed only broadside batteries. The best they could do was to hold their position, hoping for luck in the wind.
Bonnet scowled awhile at the British Jack that still flew from the _James's_ top, then went below and brought up the black pirate flag. The buccaneers, now all assembled on deck, gave it a cheerful howl of greeting as it fluttered up to the main truck. "Now we'll catch 'em, lads!" roared Herriot, and they answered him with a second cheer.
For once, however, the Jolly Roger seemed to bring bad fortune instead of good. The wind had hardly swept it easily to leeward once when it fell back against the shrouds, hardly stirring. The pirate sloop's deck righted slowly and her limp sails drooped from the gaffs. A sudden flaw in the breeze had settled about her, without interrupting her rival's progress in the least. A glum despair came over the crew. They lolled, for the most part silent or grumbling curses, against the rails, with here and there one trying to whistle up a wind. The other sloop rapidly drew away to the south.
