It is plain to me that another fit is coming on, similar to the one he had in the pavilion of Healthful House on the night we were abducted. He will have to be seized and carried down to his cabin, and I shall perhaps be summoned to attend to him.

Meanwhile Engineer Serko and Captain Spade do not lose sight of him for a moment. They are evidently curious to see what he will do.

After walking towards the mainmast and assuring himself that the sails are not set, he goes up to it and flinging his arms around it, tries with all his might to shake it, as though seeking to pull it down.

Finding his efforts futile, he quits it and goes to the foremast, where the same performance is gone through. He waxes more and more excited. His vague utterances are followed by inarticulate cries.

Suddenly he rushes to the port stays and clings to them, and I begin to fear that he will leap into the rigging and climb to the cross-tree, where he might be precipitated into the sea by a lurch of the ship.

On a sign from Captain Spade, some sailors run up and try to make him relinquish his grasp of the stays, but are unable to do so. I know that during his fits he is endowed with the strength of ten men, and many a time I have been compelled to summon assistance in order to overpower him.

Other members of the crew, however, come up, and the unhappy madman is borne to the deck, where two big sailors hold him down, despite his extraordinary strength.

The only thing to do is to convey him to his cabin, and let him lie there till he gets over his fit. This is what will be done in conformity with orders given by a new-comer whose voice seems familiar to me.

I turn and recognize him.

He is the Count d’Artigas, with a frown on his face and an imperious manner, just as I had seen him at Healthful House.
