'Then we'll put it in action,' decided the Professor. 'Not that I want to damage any more of those rascals; but there might be some accident to our rigging. Or, in a fresher breeze, which I fancy is coming, this vessel might prove slower than the other. We'll make the most of fairly smooth water and of our new possession; perhaps it will scare them.'
Once more the handy and invaluable Alphonse was in request. The natty little Frenchman seemed to have had a hand in almost everything. He could cook, as all knew, particularly his employer, while he was the tidiest of valets. Moreover, Alphonse could fight, and with a spirit that matched the Professor's. Now he showed his capacity as a gunner. He led the search for shot and powder, and then ranged himself behind the gun.
'Once I was a soldier, monsieur,' he said, 'and though I did not belong to the artillery, still I had to do with a gun; for I was in garrison where a mid-day gun was fired, and to me that duty fell. Oui, vraiment, we shall be able to manage. We must guess the charge of powder. Not too much at first, monsieur David; else there will perhaps be only pieces of us left for the pirates. We will watch where the ball strikes the water, and add more if necessary. You shall see; Alphonse will send those men a pill which will make them ill at ease and cause them to go elsewhere in search of a doctor. Ah, there is the powder; we have rammed it home. Now a piece of the sacking as a wad. Now the ball. Push with me on the rod and we will soon send it home.'
The practical little fellow slewed the muzzle of the gun round, and used the screw as he squinted along the sights. Already he had sprinkled powder on the touch hole, and presently announced that all was in readiness.
'I have laid it to be fired as we rise to the top of the swell,' he said. 'Now for a match with which to fire it.'
David had thoughtfully prepared a match, consisting of a candle end tied to a stick, and shaded by a paper hood which kept the wind from it. It was a makeshift affair, and the flame blew out twice in succession. Then the gun splashed out a stream of flame, followed by a dense volume of smoke, which, however, blew away instantly. Their ears were still tingling after the loud report when a jet of water was seen to rise a hundred yards in front of the pursuer. Instantly Alphonse tossed his hat into the air and shouted.
'Bon! Bon! The next time we will do it, yes,' he said. 'Now to sponge the gun clean, and then for a fresh charge.'
That second shot proved far more encouraging. The ball struck the surface just to one side of the vessel that was following them, and ricochetted some three or four times before it finally sank to the bottom. But the third shot plumped clear on to the deck of the enemy, causing considerable commotion.
'Bien, we have the charge at last, and with this long swivel the aim is easy,' cried the Frenchman. 'Let us try again.'
A roar of applause greeted the fifth shot, for though fired by amateurs it struck the mast of the pursuer, and as they watched, the Professor and his friends saw the rigging sway and come tottering over.
